PC-ART Version 4.0 Copyright (c) 1987,1988 by Paul Michael Stone 201 Heyden Dr. Eureka, Mo. 63025 Introduction ------------ PC-ART is a graphics drawing program that allows you to create color pictures and designs utilizing the standard color graphics adapter on the IBM PC. The following is a brief summary of its main features: * Crayon function for freehand drawing in any color with varying line boldness and shape. * Paint brush function that paints in any one of 15 different paint patterns in any combination of colors. * Pattern editor to create and save your own paint patterns. * Spray paint function which sprays random dot pattern in any color and varying spray size. * Line and Box functions with 4 different line patterns. * Circle function with concentric repeat feature. * Text function in one of two different fonts in any color and 10 character sizes. * Save or retrieve entire screen for later processing. * Snapshot function to take a picture of a portion of the screen and store it in an internal buffer. * Image library to store and later retrieve saved snapshots. * Easy to use, pop-up menu panels for selection of functions, colors, etc. * Keyboard, joystick or mouse operation. Page 1 PC-ART PC-ART was originally written to satisfy my own needs for a multi-function graphics drawing system. The current version has gradually evolved out of that original program over the years. The objective of PC-ART is to provide a full- function drawing capability without need of a joystick or mouse. Although the current version supports a joystick or a mouse, it can be run entirely from the keyboard with little difficulty. Another main feature is the use of pop- up menu panels, allowing the entire screen area to remain open for drawing. System requirements ------------------- * IBM PC/XT/AT or true PC Compatible * IBM Color Graphics Adapter or equivalent * IBM Color Display or equivalent * 256K RAM Memory * PC-DOS or MS-DOS version 2.0 or later * IBM or Epson compatible graphics printer capable of 120 dots per inch print resolution (includes IBM Proprinter) * Joystick and adapter (optional) * Microsoft compatible mouse (optional) Note: This software is tested to run on a true IBM PC with an IBM CGA adapter or equivalent. Although it should run successfully on most true PC clones, unpredictable results may be obtained on non-IBM equipment. No guarantee of any sort is made as to the performance of this software on your particular equipment. If you are a registered user (see section on distribution), I will attempt to rectify any problem of this nature that you have. However, I cannot promise that any particular problem can or will be fixed. Page 2 PC-ART Version 2.0 changes ------------------- The following is a summary of the changes and enhancements made in version 2.0 over earlier versions: * Crayon function now has varying stroke shapes when drawing bold lines (larger than 1 pixel wide). Six different shapes are provided. * The 'U' and 'P' keys no longer function with the crayon. The crayon is now moved without drawing by holding either shift key while using the arrow key. * The speed option now affects the crayon while drawing. In other words, the crayon will move and draw the number of pixels set by speed each time a direction key is pressed. * The spray can function is entirely new. This sprays a pattern of random dots on the screen. The size of the spray can be varied. * The circle and box functions have changed the way they work. They both now have a preview feature which lets you see where the shape will be drawn, before it actually is. The size, shape and position of the figure can be changed and then fixed in place. * The snapshot and partial screen erase functions are now controlled from within the box function instead of from separate function keys. * The text function now displays a box shaped cursor the exact size and shape of the current font. The arrow keys move the cursor in proportion to the character size. Holding either shift key while using the arrow keys moves the cursor one pixel at a time, allowing for fine adjustments. * An undo feature that allows you to back up if you make a mistake. * A full-function screen print utility is now provided. Page 3 PC-ART Version 3.0 changes ------------------- The following is a summary of the changes and enhancements made in version 3.0 over earlier versions: * The paint color selection menu has now been eliminated and its function merged into the pattern selection menu. The selected pattern now dictates the color to be painted, including mixed colors in the same pattern. * A pattern editor has been added allowing you to modify the standard patterns supplied with PC-ART. Modified patterns are then stored to disk and used each time you run PC-ART. * A zoom feature has been added allowing you to select any portion of the screen and enlarge it to four times its original size. Individual pixels can then be changed as desired. Any changes made to the enlarged view will be reflected when you return to the full view. * Full mouse support has been added for any Microsoft compatible mouse. To facilitate the mouse interface the function of the shift key has been modified on any PC- ART functions that use it. In each case, the effect of pressing the shift key is exactly the opposite as with earlier versions. For instance, using the arrow keys on the crayon function moves the crayon without drawing. Pressing the shift key causes the crayon to draw. Page 4 PC-ART Version 3.1 changes ------------------- The following is a summary of the changes and enhancements made in version 3.1 over earlier versions: * A new method is being utilized to save and restore drawn screens. This reduces compatibility problems with some models of non-IBM PC's. Note that screens created with previous versions of PC-ART cannot be used directly by this version. Registered users can obtain, free of charge, a conversion utility to convert older screens to the new format. * The keyboard interface has been modified to reduce compatibility problems with various keyboard layouts. * Both the zoom mode and the pattern editor have been modified to allow continuous drawing while holding the shift key, just as when using the crayon tool. * An online help facility has been added to allow the user to review the key functions while drawing. * An additional function has been added to allow snapshots taken within PC-ART to be saved as external image files rather than in the image library. This provides programmers the ability to use saved snapshots in their own programs. Page 5 PC-ART Version 4.0 changes ------------------- The following is a summary of the changes and enhancements made in version 4.0 over earlier versions: * The text drawing tool has been completely rewritten to use a different technique for creating text characters to allow more and varied text fonts. Five text fonts are supplied at this time with more to come later. As a consequence of this, the text function no longer supports the variable size feature. * The box tool now provides a flip and a reverse feature that allows any image outlined by the box to be flipped vertically or reversed horizontally. * The box tool now provides an expand feature that allows any image outlined by the box to be stretched either vertically, horizontally or both. * The box tool has been modified so that any commands affecting the box (such as erase) now include the outline of the box itself and not just the interior of the box. Prior to this the box could not be made to affect any pixels along the outer edge of the screen.

Page 7 PC-ART The distribution diskettes -------------------------- Below is a brief summary of the files contained on the PC-ART distribution diskette: PC-ART.EXE The main program execution file. PC-ART.IDX The index file to the snapshot library. PC-ART.PAT Paint pattern data file. PC-ART.SCR Image file for PC-ART logo screen. PC-ART.CFG PC-ART system configuration data. PC-ART.Fx PC-ART text font files. PC-ART.DOC The file this documentation is contained in. ARTPRINT.EXE The PC-ART screen print utility. ARTPRINT.SCR Image file for the print utility screen. ARTCONFG.EXE PC-ART system configuration utility. Page 8 PC-ART Getting started --------------- To run PC-ART on a floppy based system, simply place the program diskette in disk drive A. To run on a hard disk, copy all files on the program diskette into any directory of your choice. The only restriction is that they must all reside in the same directory and that directory must be the current directory during execution. As supplied on the distribution diskette, PC-ART is configured to run on a one floppy disk system with the program disk in drive A. Drive A is also designated as the location where saved screen images will be stored. PC-ART is also initially configured with the joystick and mouse options turned off. In order to change the location where PC-ART will store screen images to other than drive A (i.e. drive B or a hard disk directory), you must run the ARTCONFG utility. In addition this utility is also used to turn on the joystick option and configure the joystick parameters to your particular joystick, or to turn on the mouse option. The ARTCONFG utility -------------------- To run the ARTCONFG utility simply type ARTCONFG from DOS. Once the utility begins running you will be prompted to enter the drive and/or path name where you want PC-ART to store saved screen images. You can enter either a drive identifier in the case of a floppy disk drive (don't forget the colon), or a full path name for a hard disk directory (don't forget the trailing backslash). If you designate a floppy drive, a floppy diskette must be in that drive and the drive must be ready. If you enter a hard disk path name, the sub-directory that you specify must already exist. The second function of ARTCONFG is to configure your joystick if you have one. You will be prompted to indicate if you have a joystick attached to the system. If so you will be given several instructions to move the joystick which will allow the utility to adjust the proper parameters to fit your joystick. Next you will be asked if you have a mouse attached to your system. Simply respond according to your hardware setup. Page 9 PC-ART Last of all, you will be presented with a list of graphics printers supported by PC-ART. Simply enter the number next to the type of printer you have. If your printer is not on this list, try the Epson printer configuration as many models of printers support the Epson control codes. If you printer will not work, contact the author. If your printer supports 120 bit per inch graphics, PC-ART can be modified to add your printer to the list of supported printers. After you have followed all the directions, ARTCONFG will update the PC-ART.CFG file to reflect the new configuration. Note that if you are using a floppy based system, you may wish to delete the file ARTCONFG.EXE from the program diskette after you have completed the configuration process. This will free more space for use by other functions of the program. Make sure that you make a backup copy of it before you delete it in case you should need to run it again at a later date. Running PC-ART -------------- If you are running from a floppy system, make sure the PC-ART program diskette is in drive A. If you are running PC-ART from a hard disk, then make sure its sub-directory is the current DOS directory. Once you have properly prepared your system, PC-ART can be executed by simply typing PC-ART directly from DOS. The program is quite large and will take several seconds to load and begin executing, especially on a floppy disk. When the program begins executing you will see the PC-ART logo screen appear. Pressing any key at this point will erase the logo and you will see a blank screen with the crayon at its center. You are now ready to begin drawing. Most of the functions and options in PC-ART are selected by using pop-up menu panels. There are seven such panels in PC-ART, each with its own function. The various menus and their uses are described in later sections. Page 10 PC-ART Selecting a drawing tool ------------------------ There are seven different drawing tools available to you. To select a particular tool, press the F1 key. This will cause the drawing tool menu to pop-up at the top of the screen. The seven available tools will be displayed with a hi-lited box around the currently selected tool. By pressing the left and right cursor keys, move the box to the desired tool. Then press the escape key to exit the menu and return to the drawing screen. Note that the escape key is used to exit from all of the selection menus in PC-ART. For those of you who have used earlier versions of PC-ART the F10 key also still works for this purpose. The crayon tool --------------- The crayon tool is selected automatically when PC-ART first begins executing. When the crayon tool is selected a small crayon will appear on the screen. The crayon can be moved across the screen by using the arrow keys. Note that the Home, PgUp, PgDn and End keys also work by moving the crayon diagonally in that direction. The crayon can also be caused to draw a line as it moves by holding down either shift key while using the arrow keys. As long as the shift key is held down, a continuous line will be drawn wherever the crayon is moved. One additional function of the crayon allows you to draw a single point on the screen without moving the crayon. This is done by pressing the 'P' key at any time. Changing the crayon speed ------------------------- Initially the crayon will move one pixel on the screen each time an arrow key is pressed. This can be changed by pressing any of the number keys 1 thru 0 across the top of the keyboard. This number represents the number of pixels the crayon will move for each key pressed. The number 0 represents a 10. Page 11 PC-ART Note that this speed option is in effect whether or not the shift key is being used. Changing the crayon size ------------------------ Similar to the speed option, the crayon will initially draw a line that is a single pixel wide. This can be changed by holding down the Alt key and pressing any of the number keys from 1 to 5. The number 1 causes the crayon to draw a line one pixel wide, which is the default. Each number greater than 1 causes the crayon to expand one pixel on either side. In other words, a value of 2 results in a line 3 pixels wide, up to a value of 5 which is 11 pixels wide. Changing the crayon shape ------------------------- The default crayon shape is a circle. This causes the crayon to draw a circular shape as it moves, leaving both ends and corners of a line round. This can be changed by pressing the F2 key to select the crayon shape menu. As with the drawing tool menu, a pop-up panel will appear showing the six different shape options. They are a circle, square, left slanting line, vertical line, right slanting line and finally a horizontal line. Use the arrow keys to select the desired shape and press Esc to return to the drawing screen. Changing the drawing color -------------------------- The crayon can draw in any of the four colors available on the current color palette. To select a drawing color, press the F3 key. This will pop-up the color menu at the upper left side of the screen. The four available colors will be displayed. Use the up and down arrow keys to move to the desired color. Then press Esc to return to the drawing screen. Page 12 PC-ART The paintbrush tool ------------------- When the paintbrush is selected from the tool menu, a small paintbrush will appear on the screen. The brush can be moved across the screen by using the arrow keys just as with the crayon. Unlike the crayon, nothing happens to the screen when the paintbrush moves. To actually cause painting to occur, move the brush to the desired spot and press the 'P' key. The screen will then be painted starting at the exact tip of the paintbrush. Note that the paint will expand until it hits a boundary of some sort. This will either be the edge of the screen or a solid line drawn in the current drawing color. For example if you draw a white circle on the screen, then use the paintbrush at any point inside that circle, the paint will expand to fill the entire circle and then stop. Selecting a paint pattern ------------------------- The paintbrush can paint in any of fifteen different patterns. This pattern can be a solid color or any pattern of colors. To select a paint pattern, press the F7 key to see the paint pattern menu. Select the desired pattern and return to the drawing screen, just as with any other menu. The pattern editor ------------------ PC-ART is supplied with fifteen standard painting patterns. The pattern editor lets you change any of these patterns to suit your own needs. To edit a pattern, select the pattern menu by pressing the F7 key, and use the arrow keys to select the pattern to be edited. Then press the 'E' key to select the editor. The screen will be erased and the pattern edit screen will appear. The area at the center of the screen will contain a large box on the left which is an enlarged view of the pattern to be edited. The small box to the right labeled 'Current color' displays the currently selected color to be used in editing the pattern. Page 13 PC-ART The edit color can be changed at any time by pressing the 'C' key. Each press of the 'C' key toggles the current color thru each of the four colors in the current palette. When the edit screen first appears, a flashing cursor will appear in the upper left corner of the pattern box. This cursor can be moved to any position in the pattern using the arrow keys. Pressing the 'Return' key will change the color of the spot under the cursor to the current edit color. In this way any spot in the entire pattern can be changed to any color desired. Holding down the shift key while moving the cursor causes the editor to drawn the current color continuously just as with crayon tool. When you are done editing the pattern, press the 'Esc' key to return to the drawing screen. Any changes made to the pattern will be reflected in the pattern selection menu. Any changes made are also stored in the pattern file on the disk so that PC-ART remembers all changes you make. The spraycan tool ----------------- When the spraycan is selected, a small circle will appear on the screen. This circle can be moved around on the screen by using the arrow keys as before. Pressing the 'S' key at any time causes a spray of random dots to be put on the screen. The circle on the screen indicates the size of the spray pattern. The spraycan sprays in the currently selected paint color which can be changed just as with the paintbrush. The size of the spray can also be changed, just as with the size of the crayon, by holding down the Alt key and pressing a number key 1 thru 5. The circle tool --------------- When the circle tool is selected a small circle will be drawn on the screen. Just as with the other tools, the circle can be moved anywhere on the screen by using the arrow keys. Page 14 PC-ART The shape and size of the circle can also be changed by holding down the shift key when using the arrow keys. When the shift key is pressed, the left and right arrow keys affect the size of the circle. Pressing the left arrow shrinks the circle and pressing the right arrow expands it. The up and down arrows work slightly different. Pressing the up and down arrows causes the circles shape to change. The up arrow causes the circle to shrink from top to bottom while the down arrow causes it to stretch in this direction. When the circle is in the desired position, pressing the 'C' key causes the circle to be permanently glued in position. Additional circles can then be drawn starting from that point. Note that the circle will draw in the currently selected drawing color and that the speed option is also in effect (see the crayon function for details on the speed option). The box tool ------------ When the box tool is selected, a small box is drawn on the screen. This function works very similar to the circle function with a few minor differences. Like the circle, pressing the arrow keys moves the box anywhere on the drawing screen. When the shift key is pressed, pressing the left or right arrow keys causes right side of the box to move in that direction, shrinking or expanding the box horizontally. Pressing the up or down arrow keys causes bottom of the box to move, shrinking or expanding the box vertically. The diagonal keys also work, adjusting both the right and bottom of the box at the same time. Unlike the circle, the box can be drawn in solid lines or in any of three different dashed or dotted lines by changing the line pattern. This is done by pressing the F6 key to select the line pattern menu. As with any menu, select the desired option and press Esc to return to the screen. The box tool also has two additional functions that are performed by pressing either the 'F' or the 'R' keys while the box is on the screen. The 'F' key causes the contents of the box to be flipped vertically, while the 'R' key reverses the box contents horizontally. Page 15 PC-ART Another additional function of the box tool is the expand feature. This allows you to stretch the contents of the box either vertically, horizontally or both. Simply position the box around the area to be expanded and press the 'X' key. Now use the direction arrows to change the shape of the box. Note however that only the right hand and bottom sides of the box will move and the box can only be made bigger, not smaller. Finally press the return key and the contents of the original box will be expanded to fill the new box. On last feature of the box tool is the erase feature which will be explained in a later section. The line tool ------------- When the line tool is selected, a short line will be drawn on the screen. Pressing any of the arrow keys will move one end of the line in that direction while the other remains fixed. Pressing the 'L' key at any time fixes the line in its current position and the fixed end of the line is moved to the new end. In this way a series of continuous lines can be drawn from one point to the next. By holding the Alt key and pressing 'L', the same line will be drawn, but the fixed end will remain at its original point. In this way a ray pattern can be drawn from a fixed point. Last of all, the fixed end of the line can be moved to the point at the other end of the line, without drawing a line, by pressing the 'P' key. As with the box, the drawing color, speed, and line pattern options are all in effect for the line tool. The text tool ------------- When the text tool is selected a small box will be drawn on the screen. Pressing any of the regular typewriter keys on the keyboard will cause the corresponding character to be printed in the exact location of the box. The box will then skip one space to the right. Page 16 PC-ART The text box can be moved on the screen, without typing characters, in two ways. By pressing any of the arrow keys, the box will skip across the screen in direct proportion to the size of the characters. In other words, very similar to the way the cursor moves on a text editor. Holding down either shift key while pressing the arrow keys moves the box a single pixel at a time, allowing for fine adjustments. Changing the text font ---------------------- Five different text fonts (designs) are available. The current text font can be changed at any time by pressing the F4 key to display the font menu. Simply select the desired font and press Esc to return. The zoom function ----------------- PC-ART provides the ability to select a portion of the screen and enlarge it so that very fine modifications can be made to the picture at that point. The zoom function is selected at any time from the main drawing screen by holding down the 'Alt' key and pressing the 'Z' key. A large box will appear on the drawing screen. This box can be moved around on the screen, just as with the box tool. Move the box to the area of the screen to be enlarged and press the 'Return' key. The screen will clear and the area of the screen contained in the box will be enlarged to four times its original size and displayed on the screen. Each pixel or dot on the original screen area will be displayed as a small square on the zoom screen. Once the zoom screen has been drawn, a flashing cursor will appear in the upper left corner. As with the pattern editor, the cursor can be moved with the arrow keys. Pressing the 'Return' key changes the pixel under the cursor to the current drawing color. As before, the cursor can be made to draw continuously while moving by holding down the shift key. While in zoom mode, the current drawing color can be changed at any time by pressing the F3 just as you would in any other PC-ART function. Page 17 PC-ART When all changes have been made to the zoom screen, pressing 'Esc' will exit the zoom function. The original drawing screen will be returned and any changes made to the zoom screen will be made on the drawing screen. Saving an entire screen image ----------------------------- When you have completed drawing a screen you can save the entire contents of the screen for later retrieval or for use in the print utility. To save a screen, hold down the Alt key and press F2. You will be prompted for the name of the file you wish to save the screen under. You can type up to an eight character name. Do not type a file extension, as an extension of 'PIC' is automatically added to the file name. Retrieving a saved screen image ------------------------------- A previously saved screen image can be retrieved onto the screen for further editing by pressing the F1 key. Once again you will be prompted for the file name. As before, do not include the file extension. Note that screen images saved with versions of PC-ART prior to version 3.1 are not compatible with version 3.1 or later. A conversion utility which will convert older screen images to the new format used by version 3.1 is available free of charge to registered users who request it. Taking a snapshot ----------------- PC-ART provides the ability to take, and store, a snapshot of any portion of the drawn screen. This feature allows you to outline any portion of the screen and store that image for later use. To take a snapshot, start by selected the box tool. Move and adjust the box as you normally would until the box exactly outlines the area of the screen that you wish to take a snapshot of. This area can be of any size. Page 18 PC-ART Now press the 'S' key. A frozen image of just that piece of the screen will then be stored in memory for use as described below. Retrieving a snapshot --------------------- Once the box tool has been used to take a snapshot of a portion of the screen, this snapshot can be retrieved any number of times and redrawn on the screen. To retrieve a snapshot, hold down the Alt key and press F3. The image currently in the snapshot buffer will appear in the upper left corner of the screen. You can then use the arrow keys to move the image around on the screen until it is in the desired location. Pressing the 'G' key will then glue the image in place. This operation can be repeated any number of times with the same image. By using this feature with the erase (see the section 'Erasing a portion of the screen') and snapshot options of the box tool you can take a snapshot of a shape, erase it and then redraw it in a different place. This provides a simple way to move drawn images on the screen. Saving a snapshot to an external file ------------------------------------- PC-ART provides the ability to save snapshots to an external file in the same format as when saving entire screens. This allows BASIC programmers to use snapshot images in their own programs. To use this feature you must have already taken a snapshot using the box tool. To save a snapshot, hold down the Ctrl key and press F2. You will be asked for a file name to save the image in. The rules for entering the file name are the same as those for saving an entire screen, except that the extension '.IMG' is automatically added to the file name. Saving a snapshot to the library -------------------------------- PC-ART includes a special image library which can store snapshot images from the screen. To use this function you must have already made a snapshot using the box tool. Page 19 PC-ART To save a snapshot, hold down the Alt key and press F6. You will then be prompted for the name to store the image under. As with a screen image you can type in up to eight characters in the name. Then press enter to store the image in the library. Note that doing so does not erase the snapshot from the internal buffer. Retrieving a snapshot from the library -------------------------------------- You can retrieve a snapshot from the library at any time by holding down the Alt key and pressing F5. A pop-up panel will appear which will list up to nine snapshots currently stored in the library. If there are more library entries than will fit on the screen, you can page through the library by using the PgUp or PgDn keys. Once the desired entry is displayed on the screen, use the up and down arrows to position the lit box around it. Pressing the return key then retrieves the snapshot image. Two things happen at this point. First of all the image is stored in the internal snapshot buffer, just as if you had made a snapshot from the screen. Secondly the retrieved image is displayed in the upper left corner of the screen. You should proceed at this point exactly as if you had pressed Alt-F3 to retrieve a snapshot. Tips for BASIC programmers -------------------------- Saved screen images as well as snapshots saved to disk can be used and displayed in your own BASIC programs quite easily. All screen images and snapshots saved with PC-ART are saved from an integer table array using the BSAVE command. They can therefore be loaded into any other BASIC program using the reverse process. The images can be loaded into an integer array using the BLOAD command and then the PUT command can be used to display them on the screen. Saved snapshots, because they are only a piece of the screen, can be displayed anywhere on the screen. Page 20 PC-ART Below is a sample BASIC program that loads and displays a screen named ART: 100 DIM ARRAY(8224) 110 OFFSET = VARPTR(ARRAY(0)) 120 BLOAD "ART.PIC",OFFSET 130 SCREEN 1 140 PUT (0,0),ARRAY,PSET Erasing a portion of the screen ------------------------------- You can erase a portion of the screen by using the erase feature of the box tool. Start by selecting the box tool from the tool menu. Then use the arrow keys to move and adjust the box until it exactly outlines the area you wish to erase. This area can be of any size. Then simply press the 'E' key and the area within the box will be erased. Erasing the entire screen ------------------------- At any time you can erase the entire screen by holding down the Alt key and pressing F7. You will be prompted to make sure that you do indeed wish to erase the screen. Answering 'Y' will then erase the screen. Answering 'N' will cancel the erase and return to the screen. The undo function ----------------- At any time you can undo the latest changes to the screen by holding down the Alt key and pressing the 'U' key. This will erase all changes made since the current tool was selected from the tool menu. Changing tools permanently freezes the screen contents. An example would be if you had drawn a circle on the screen with the circle tool, and then switched to the paintbrush. After painting the circle, you decide that you wished to use a different pattern. Pressing Alt-U will remove the paint but leave the circle intact. Page 21 PC-ART Changing background color and palette ------------------------------------- The current background color displayed on the screen can be changed by pressing the F8 key. Each time you press the key the color will cycle through one of its sixteen different options until finally arriving back at the original black background. The current palette represents which three colors are available to you for drawing or painting at any one time. Pressing the F9 key flips between the two available color palettes. The colors available in the two palettes are shown below: Palette 1 - Green, Red, and Brown Palette 2 - Cyan, Magenta and White Using a joystick ---------------- When a joystick is attached to a standard game adapter port on the PC you can make use of the joystick to help you draw with PC-ART. In all functions of PC-ART, the joystick acts exactly as if you had pressed the directional arrow keys. Moving the joystick to the left is just like pressing the left arrow key and so on. The left button (red on some models) on the joystick behaves exactly like either shift key on the keyboard. In other words if you move the joystick while holding down the button, PC-ART will perform as if you had pressed an arrow key while holding either shift key. In addition, the right button will perform a number of functions depending on which tool is currently being used: Spraycan - same as pressing 'S' Circle - same as pressing 'C' Box - same as pressing 'B' Line - same as pressing 'L' All others - same as pressing 'Return' Page 22 PC-ART Using a mouse ------------- When a mouse is attached to your system you can make use of the mouse to help you draw with PC-ART. The mouse is used in a very similar manner to the joystick. As with the joystick, moving the mouse in various directions is the same as pressing the direction arrow keys on the keyboard. Likewise the left and right mouse buttons behave exactly like the same buttons on the joystick. Getting help ------------ PC-ART provides an online help facility that can let use review the various key commands and the function while drawing in PC-ART. You can invoke the help feature at any time by holding down the Alt key and pressing the H key. This will cause the first help screen to appear. Press the return key to obtain additional screens. Pressing Esc at any time will restore the screen as it was prior to requesting help and you will be returned to whatever you were doing at the time. The ARTPRINT utility -------------------- Once a graphics screen image has been created using PC-ART, the ARTPRINT utility can be used to print a hardcopy of the screen. Prior to using ARTPRINT you must have saved the screen you wish to print using the Alt-F2 function of PC- ART. To use the print utility simply type ARTPRINT from DOS. The print option screen will then appear. When it does, you will see a place to enter a screen name and three option selection windows across the bottom. To print a saved screen you must first select the desired print options, if the displayed default options do not meet your needs. Any of the options in the option windows can be selected by holding down the Alt key and pressing the first letter of that option. Page 23 PC-ART The first option is the print mode. There are two print modes; portrait and landscape. In portrait mode the screen will be reduced in size to print upright on the paper just as it appears on the screen. In landscape mode the screen will be rotated 90 degrees and printed on its side, allowing the entire 8 1/2 by 11 sheet of paper to be used. The second option is the print position. In portrait mode the printed screen will use only half of an 8 1/2 by 11 inch sheet of paper. Selecting top or bottom indicates where on the sheet of paper the screen will print. Since landscape mode uses the entire sheet of paper, the print position option is ignored when landscape is selected. The last option is print type. In normal print, any shapes drawn on the screen will appear as dark lines on a white background with colors being printed in shades of gray. In reverse print, all images are printed as white on a black background. Note that reverse print should be used sparingly as printing a solid black background is hard on both your printer and the ribbon.
