COMMAND SUMMARY Commands for PC-KEY-DRAW are divided into two pri- mary types. Type 1 are those that can be issued in the CURSOR MODE (any time the cursor can be moved about on the screen) and type 2 are the commands that are called from within a particular function. Basically type 1 commands pertain to general oper- ation, while type 2 commands pertain to a specific drawing function. The help file in PC-KEY-DRAW and the Command Summary sheet (available from OEDWARE) are similar to the contents of this chapter, which is arranged by command. See Chapter 9 DEFINITIONS & ADDITIONAL INFORMATION for additional detail of the commands. COMMAND SUMMARY 4-1 SHORT FORM: Cursor Mode Cursor keys <1-9> move cursor around on screen at speed set by F9. Shft-Cursor keys <Shft>-<1-9> move the fixed corner of a box or center of a circle. <Ctrl-Home> sets the display to Screen 1 if screen is not 1. Allows panning or paging through pages and layers if screen is already set to 1. <Home> sets screen 1 to Page 00 or layer 0. <End> sets screen 1 to last page or layer created. <PgUp> moves through pages and layers one page or layer up. <PgDn> moves through pages and layers one page or layer down. <Cursor keys> Pan in page mode by 1/2 screen. <Ctrl-End> sets screen to Screen 2. <Ctrl-PgUp> Moves up through screens. <Ctrl-PgDn> Moves down through screens. <Esc> Stops current operation. <Shft-Tab> Switches between high resolution and medium resolution mode. <Backspace> backsteps during b-spline and line/dot/parallel/spoke drawing in F6. <Alt-0 to 9> jumps to screen location previously set with <Ctrl-j>. <$> Sets screen aspect ratio. <*> Controls prompt display during macro playback. <+> increases cursor step by one. <-> decreases cursor step by one. <(> shifts entire display to the left. <)> shifts entire display to the right. <[> rotates polygon or rose counterclockwise. <]> rotates polygon or rose clockwise. <{> rotates polygon or rose counterclockwise in 90 degree increments. <}> rotates polygon or rose clockwise in 90 degree increments.

Picture is brought in to the animation mode. <O> retrieves drawing and places it to lower right of current cursor position. <a> animate allows a previously copied or erased area to be moved around the screen with the cursor. <m>,<M>,<Ctrl-m> and <Alt-m> move area previously erased or copied to lower right of cursor, each with a different syntax. <s>,<S>,<Ctrl-s> and <Alt-s> smear the copied object with each step of the cursor using dif- ferent syntax. <r>,<R>,<Ctrl-r> and <Alt-r> replicates object with each cursor step. <l> inserts a single horizontal line at the cursor position. <Alt-l> deletes a single horizontal line at the cursor position. <x> sets x and y coordinates of cursor. <n> or </> or < > or <Esc> exits function. COMMAND SUMMARY 4-12 F8 Files & Exit <d> directory of selected disk. <s> saves the current drawing. <o> old-retrieves a stored drawing from disk. <O> old-displays screen files on disk and loads them for sequential display using Pg-Dn. <Ctrl-o> template-allows a template screen to be called up. Disables updating of disk. Retrieve working screen with F10 <w> or <W>. <Alt-o> brings in screens using different display methods for slide shows. <f> fresh-clears screen and starts again. If the current drawing has not been saved on disk it will be lost. <F> fresh-clears screen and layers or pages from workspace disk. prints graphics screen on line printer #1 <Ctrl-p> zoom prints partial screen. Enclose area to be printed in box.

User must specify full name including drive. <K> rename file on disk. <e> exits program completely and returns to DOS. <x> sets x and y coordinates of cursor. <n> or </> or < > or <Esc> exits function. COMMAND SUMMARY 4-13 LONG FORM: Cursor Mode Cursor keys <1-9> move cursor around on screen at speed set by <F9> or <+> and <->. Shft-Cursor Keys <Shft>-<1-9> use during drawing of circles, rectangles, polygons, ellipses and several others to adjust the starting point of the object being drawn. For example when draw- ing a circle the Cursor Keys adjust the size of circle while the Shft-Cursor Keys move the circle around on the screen. With a rectangle the Cursor keys move one corner while the Shft- Cursor keys move the opposite corner. <Ctrl-Home> sets the display to Screen 1 if screen is not 1. Allows panning or paging through pages and layers if screen is already set to 1. <Home> sets screen 1 to Page 00 or layer 0 <Ctrl-Home> returns to Page 00 or layer 0 with- out saving screen you are currently on. <End> sets screen 1 to last page or layer created. <PgUp> moves through pages and layers one page/layer up. <PgDn> moves through pages and layers one page/layer down. <Cursor keys> Pan in page mode by 1/2 screen. <Ctrl-End> sets screen to Screen 2 no matter what the screen is to begin with. Screen 2 is used for the visual layer when layers are active. Screen 2 is ideal for a temporary work space when layers are not in use. <Ctrl-PgUp> Moves up through screens. Screen 1 is the top screen. COMMAND SUMMARY 4-14 <Ctrl-PgDn> Moves down through screens. Screen F7 is below Screen 2. Screen Title is below Screen F7. <Esc> Stops current operation and refreshes screen to what it was before the last action was started. <Shft-Tab> Switches between high and medium resolu- tion. Use <Alt-r> to switch to high resolu- tion. The current drawing mode will be saved as the default mode is <Ctrl-s>tatus is selected and saved. <ENTER> The Enter/Return key is used to complete functions, mark points, take default values. The first mouse button is used as the <ENTER> key. During line drawing the <ENTER> key is used to mark line end points and continue draw- ing. References to marking or ending usually refer to using the <ENTER> key. <Space Bar> brings up the Function selection menu if no functions are currently active. <Space Bar> is active during line drawing with F6 <l> or <c> to temporarily suspend line drawing and display the cursor. <$> Sets screen aspect ratio. The aspect ratio is the ratio between the horizontal pixels and vertical pixels. An aspect ratio of 1.0 in color or 2.0 in high res gives good results. Adjust the screen ratio as desired to display circles as circles and not ellipses. You may want to match to your printer rather than to the screen. The screen aspect ratio can also be varied as desired for a number effects, ie. adjusting spray paint or rotating in an ellipse. COMMAND SUMMARY 4-15 <+> increases cursor step by one. The new cursor step is retained and can be toggled with <F9>. <-> decreases cursor step by one. The new cursor step is retained and can be toggled with <F9>. <(> shifts entire display to the left for use with graphics boards that need to be centered. <)> shifts entire display to the right. Use <(> and <)> with some graphics cards to properly center screen. <[> rotates polygon or rose counterclockwise at steps set by <F9>. <]> rotates polygon or rose clockwise in steps set by <F9>. <{> rotates polygon or rose counterclockwise in 90 degree increments. <}> rotates polygon or rose clockwise in 90 degree increments. Polygons are rotated as you watch, but to rotate a rose you must first start the rose (which resets the rotated angle to zero) and then with the circle displayed rotate to the desired angle. </> works the same as <Space Bar> <?> displays help information. Works like <H>. COMMAND SUMMARY 4-16 <*> toggles prompt line display for playback. When writing macros that will be used as slide shows or demos it is often desirable to turn of the prompt line and the cursor. Use <*> once to turn off the prompt line and twice to also turn off the cursor. It may be best to add the appropriate line to the macro after it is writ- ten, since seeing the prompt and cursor can aid in debugging. The macros will run much faster if the prompt is turned off. <Alt-1> sets cursor to 0,0 (top left corner). <Alt-0 to Alt-9> jumps to the screen position pre- viously assigned to that key. These must first be defined with <Ctrl-j>, which will create a small file KD-DRAW.JMP. If a particular key is not assigned the cursor will jump to 0,0. <5> displays color value that cursor is over. This lets you know what color you are over when working on a black and white screen in the color mode of the program. sets background value. The background value is used for a number of functions, including removing the lines during rubberbanding of circle, box, polygon. The current setting of the background is displayed in column 40 of the prompt line. Reverse video operations change the setting of the background value. <Alt-F10> also sets the color of the background. Nor- mally the background color is set to the pre- dominate color of screen, but there are many times when it is desirable to set it to another value. COMMAND SUMMARY 4-17 <C> switches cursor to last center of a circle or centers animated area horizontally on screen. <Alt-c> toggles through three cursor types. A double dot, arrow, or full screen cross hairs are available. Which cursor you use depends on what you prefer and will vary with the type of drawing you are working on. Your favorite cur- sor type can be saved as the default from the Status screen. <Alt-d> displays the DOS date at the specified screen location. <g> sets grid to display as dots. You must specify the spacing of the grid in the units of the scale being used. <g> will also turn the grid off if it is on as dots of lines. The current color set by <F10> will be used as the grid color, until the grid is turned off. <Alt-g> sets grid to display as lines. Use <g> to turn it off. The current color set by <F10> will be used as the grid color, until the grid is turned off. <h> selects help menus. The first time brings in the menu in the top left corner of the screen (if it is currently off). Selecting it a sec- ond time displays the help file for the CURSOR MODE. <H> toggles help menus as above or turns off the menu if is on. toggles isometric drawing mode. A 1 indicates that the isometric mode is off, while a 2 means the mode is on. The isometric mode changes the cursor key movements so that instead of moving at 45 degree angles the cursor moves at 30 and 60 degree angles. COMMAND SUMMARY 4-18 <Ctrl-j> or <Ctrl-ENTER> allow screen positions to be set and remembered and assigned to <Alt-0 thru Alt-9>. KD-DRAW.JMP will be created the first time this function is called. This fea- ture works best if the program is run from a RAM disk. <k> keeps the screen in memory as it currently appears. Use this with functions like <F7 a>nimate and <F7 s>mear and with functions like <F2 r>ectangle, <F3 c>ircle, and <F2 p>olygon when the ackground color is set to something other than the background of the screen. <Alt-k> activates key macro for <r>un, <c>reate, or <e>nd. See Key Macro for details on operation. Both <r>un and <c>reate will ask for a file name to use. Entering a single drive letter only will display the files on the drive with appropriate extension. <l> turns display of visual layers on and off. Once layers are on they can only be turned off with <Alt-l>. <L> sets active and visual layers as desired. <Ctrl-l> combines Screen 1 with the visual layers of Screen 2 to create a new visual layer and starts next layer with a fresh screen in Screen 1. This is the primary method of initializing the use of layers. <Alt-l> turns layers off and pages back on. This differs from <l> which simply stops displaying the visual layers when turned off. COMMAND SUMMARY 4-19 <m> mark measure point. Measure read out on prompt line is set to zero. Use at any time. Some functions will set <m>ark measure for their own use. <M> switches cursor to last marked point. Some operations will mark a point for measure, such as <F2 r> and <F3 c>. <Alt-m> sets screen scale based on measured dis- tance. Use <m> first. <Ctrl-p> plays music using the BASICA PLAY state- ment syntax. For use primarily in macros. See your BASICA manual for details on using the play command. <Alt-p> sets pause length for macro playback in seconds. <Alt-p> has no effect except in a macro playback. <Q> controls cursor movement quality. Quality off allows faster motion. Quality on ensures equal cursor steps. Key macro automatically sets quality on. Do not turn the quality off in a macro since cursor movement will not be faith- fully recorded. <R> Refresh the screen with current picture. <Alt-r> forces the screen to high resolution mode. Use in macros that must start in high resolu- tion. <Shft-Tab> toggles between high and medium resolution. High resolution is 640X200 with 2 colors, while medium resolution is 320X200 with 4 colors. Which resolution used depends on final output desired. COMMAND SUMMARY 4-20 <s> Show only active screen, without cursor or prompt line, useful for taking slides from screen. During macro play back the macro will stop and wait for any key to be hit. <S> Same as <s>, but shows both active and visual layers. <Ctrl-s> Switch to the status/configuration screen. A number of parameters can be set and kept as the default to be used by the program each time the program is run. This is the same screen that is displayed the first time the program is run or when ever KD-DRAW.DFT is removed from the disk. <Alt-t> displays the current time on the screen at the specified position. Useful for macros that will be run continuously in a show or store environment. updates workspace #1 and declares that current screen is Screen 1. The previous contents of Screen 1 will be lost. Retrieve with <F8 w>. updates workspace #2 and declares that current screen is Screen 2. The Previous contents of Screen 2 will be lost. Retrieve with <F8 W>. <Alt-v> sets visual horizon of screen. This is the point where animated objects will disappear when moved below the set level. The visual horizon setting is provided primarily for spe- cial effects during macro playback. COMMAND SUMMARY 4-21 <w> sets line width from 1 to 32. <w>idth also controls the width of circles, rectangles, polygons and b-spline curves. Width can be set greater than 32 for circles, polygons, b-spline, and rectangles. SCNSHOW.MCR uses a very large width setting with circle to fade out the screen showing the girl and the sheep in the meadow. <x> allows direct coordinate entry. Enter the scaled x and y coordinates. The cursor will jump to the new point. COMMAND SUMMARY 4-22 F1 Modification <r> allows rotation about a point in the plane of the screen. First select center of rotation, next define object. Follow prompts. *C*-<r> will rotate only the current color as selected by <F10>. <Alt-r> to rotate all three colors of an object. A screen aspect ratio of 1.0 in medium resolution or 2.0 in high resolution provides the cleanest rotation, while other aspect ratios can be used for interesting effects. Rotation can either be used to replace the object with the rotated form of the object or used to give multiple steps of the object about the center point. COMMAND SUMMARY 4-23 <R> revolves an object about a horizontal or verti- cal axis. Use like <r> by marking axis center, and any two opposite corners. <Ctrl-r> rotates left half of screen 90 degrees. Part of the right side of the screen may be lost so you may want to store the screen first. <a> again-allows the same object to be rotated or zoomed again with a new angle/size. <a>gain can be particularly useful when you are not sure of the exact angle or zoom amount needed. If this is the case try the following to rotate an object: 1. Select <F1>. 2. Select <r> or <Alt-r> and enclose the object. 3. Hit <ENTER>. 4. Specify a 0 rotation angle and a 0 step amount. (The object will disappear!) 5. Enter <y> when asked if Correct?. 6. Select <F1>. 7. Select <a> and specify the desired angle and a step of 1. 8. If the position is correct respond <y> if not respond <n> and repeat from step 6 until it is correct. <Alt-a> again-allows a previously rotated object to be zoomed and vice versa. COMMAND SUMMARY 4-24 <z> zooms an object either up or down. Does not change drawing scale. Use like <r> by marking center, and any two opposite corners. The cen- ter location is particulary important when using multiple steps to produce 3-D effects. Placing the center far away from object results in a stretche 3-D effect when using step. *C*-will zoom only current color as selected by <F10>. <Alt-z> to zoom entire object. (all colors) <Alt-z> is identical to <z> in all aspects except how colors are handled. Both <z> and <Alt-z> allow a step to be set for zooming. This allows you to create 3-D effects, that work especially well with certain text fonts. COMMAND SUMMARY 4-25 <Z> zooms the entire screen up or down, changing scaling accordingly. A screen aspect ratio of 1.0 in color or 2.0 in high resolution gives the best results for zooming. When zooming with <z>, <Z>, or <Alt-Z> you will be asked to Enter Scale Factor. The number entered multiplies the current screen scale, thus scale factors greater than one shrink the object relative to the screen while scale fac- - tors less than one expand the object on the screen. Use <Space Bar> or </> to enter the Zoom Factor instead of the Scale Factor. The Zoom Factor multiplies the object size, thus factors greater than one expand the object, while factors less than one shrink the object. COMMAND SUMMARY 4-26 <Ctrl-z> zooms portion of screen for editing on a pixel by pixel basis. Selecting <Ctrl-z> a sec- ond time will allow work on 8 screens at one time. The size of the pixel screen corresponds to the size of the patterns used in <F5 f>ill. While in the pixel (FATBITS) mode the colors of the pixels are entered directly as 0,1,2, or 3. To draw with a color use <t>race followed by the color number, then move the cursor to leave the line behind. Use <t> a second time to turn off the trace. Exit pixel editing with <Esc>. While in the pixel editing mode, text mode files can be brought in. This is designed for macro play back and has little use in drawing edit- ing. The text screens should be saved in a BSAVE format. <o>ld prompts for a file name to load. If multiple screens are loaded when entering the FATBITS mode use <Ctrl-PgDn> and <Ctrl-PgUp> to move through the pages. COMMAND SUMMARY 4-27 <m> mirrors image of an object defined in box. Select mirror line orientation. The original image remains intact as a duplicate mirror image is made. Mirroring of an object is one of the most useful functions available in any drawing/paint pro- gram. Many objects are symmetrical, but when drawing by conventional means, ie. paper and pencil, you must draw both sides of an object independently. With PC-KEY-DRAW you can draw one side of the object and then use <m>irror to make it symmetrical. <M> mirrors entire screen either horizontally or vertically. Mirroring of the entire screen can be a necessity in creating certain special effects. For example when using <F1 S> or <F1 Ctrl-s>lide to create a bowl effect (see Library disk #2 for several macros) the screen must be mirrored because slide only works from left to right. COMMAND SUMMARY 4-28 <f> flips/rotates object through desired view angle, thus compressing it. <F> flips/rotates full screen through desired view angle. Think of <f>lip and <F>lip as follows: Draw a circle on a piece of paper. Hold the piece of paper in your hands so that it is perpendicular to your line of sight, ie the circle and paper are in full view. Rotate the paper and notice how the circle turns to an ellipse. <f> and <F> perform the same function on the screen. COMMAND SUMMARY 4-29 <v> reverse video - switches colors 0 to 3; 1 to 2; 2 to 1; 3 to 0. Works on the entire screen. The ackground value is changed accordingly. <V> reverse video - switches colors 0 to 1; 1 to 0; 2 to 3; 3 to 2. Works on the entire screen. The ackground valve is changed accordingly. <Ctrl-v> reverse video - switches colors 0 to 2; 1 to 3; 2 to 0; 3 to 1. Works on the entire screen. The ackground value is changed accordingly. <Alt-v> XORs screen with set value. An XOR with 255 is equivalent to <v>. A random value is assigned each time <Alt-V> is accessed. You can use the default random value or enter your own number. Works on the entire screen. Reverse video works on a full screen only. To reverse only an object is necessary to copy the object and move it to an unused screen, perform the reverse video, recopy only the object and return it to the original screen. COMMAND SUMMARY 4-30 <s> slides object either horizontally or vertically by a given number of steps. Use slide to dis- tort a drawing. It is ideal for creating italic letters. <s> uses a slide factor of 1. <S> slides entire screen. In the same fashion as <s>. <S> uses a linear slide factor of 1. <Ctrl-s> slides entire screen as above only to a power (slide factor) from 2 to 4. Slide distorts the screen by shifting it line by line. The amount each line is shifted is cal- culated based on the step size (default=10) and the power factor. The direction of the slide is either vertically up or down, or horizon- tally left and right. A number of macros are included on Library Disk #2 that make use of slide to create a bowl effect with what is on the screen. COMMAND SUMMARY 4-31 <c> calculates area and center of area for object. By looking for the color set with F10. The area calculation is based on the screen scale and lit pixels. To get the area of a circle the circle must be completely filled in with the same color, otherwise calculate will return a value closer to the perimeter of the object. <Alt-c> calculates mass and center of mass for object. Operates much the same as <c> only all colors are calculated for and weighted based on user supplied density factors. <x> allows direct coordinate entry. Enter the scaled x and y coordinates. The cursor will jump to the new point. <n> or </> or < > or <Esc> exits function. COMMAND SUMMARY 4-32 F2 Box & Figure <r> rectangle -displays box as cursor is moved. The <Shift> key can be used with the cursor keys to adjust the first corner of the box. The diag- onal length of the rectangle is displayed on the prompt line. F2 |1 Creates square r |1 RIGHT |6 DOWN |6 ENTER |2 <R> same as <r> only box is copied for use with <F7 a>nimate, move, etc. The line width setting effects the rectangle width. A width setting of 1 draws a rectangle one pixel wide, while a width setting of 5 draws a rectangle five pixels wide, and so on. For lines the maximum width is 32, for rectangles the maximum width is 32,000 pixels. Macro spe- cial effects using <r>ectangle with <w>idth allow the screen to be erased from some line outward. <Alt-r> produces a rectangle filled with the color set by <F10>. To draw a square, use the 45 degree keys (Cursor Pad Keys 1, 3, 7, and 9) to move vertically and horizontally an equal amount. To draw a rectangle with known length on both sides move the cursor first horizontally the desired distance, select <m>ark measure and then move vertically the desired position. COMMAND SUMMARY 4-33 <s> produces shaded box with choice of <l>ight, <m>edium, and <h>eavy shade Use <F10> to set color. Mark any two opposite corners. F2 |1 Creates shaded square s |1 with medium shade density. RIGHT |6 DOWN |6 ENTER |1 m |1 ENTER |1 <S> same as <s> only box is copied for use with <F7 a>nimate, move, etc. An outline of the area to be shaded is displayed as the cursor is moved to set the size. When <ENTER> is selected the user is prompted for the shade density and the area is drawn. COMMAND SUMMARY 4-34 polygon inscribed in circle. Enter number of any number of sides. The polygon is displayed as it is sized and positioned with the cursor. Use <[> and <]> to rotate the polygon as you position it. <F9> controls the amount the poly- gon is rotated with each step. F2 |1 Creates seven sided polygon p |1 7 |1 RIGHT |6 ENTER |2 <a> arrow-places arrow head at cursor location either pointing p, <d>own, <l>eft, <r>ight, <e> up-right, <f> down-right, <g> down-left, <h> up-left. Use u or d to upsize or downsize the arrow. The arrow size is remembered and used the next time arrow is called. Selecting <ENTER> from Cursor Mode will continue to place the last arrow drawn at the cursor position, until another function is selected. <o> outlines area. The program will search the enclosed area for the background color (set with <Alt-F10> bordering on the other three colors and produce an outline using the color set with <F10>. <x> allows direct coordinate entry. Enter the scaled x and y coordinates. The cursor will jump to the new point. <n> or </> or < > or <Esc> exits function. COMMAND SUMMARY 4-35 F3 Curve Draw <c> circle-draws a full circle. The location of the cursor when <c> is selected will be the center of the circle. After marking the center, move the cursor to the desired radius. The length of the radius is shown on the prompt line and the circle is displayed. The center can be shifted with the numeric keys corresponding to the cur- sor keys. Select <F3> again or <ENTER> to mark the radius and draw the circle. If circle is not of desired roundness, select <$> and change screen aspect ratio. F3 |1 Creates circle c |1 RIGHT |5 ENTER |2 The width of a circle is controlled with <w>idth from the Cursor Mode. As with rectangles there is effectively no limit on the width a circle can have. SCNSHOW.MCR uses a very wide circle of color 0 to perform a screen wipe of the GIRL screen. Ctrl-c> draws the center line for a circle. Start in the center of the circle and use just like <c>. The properly sized center lines will be drawn after an <ENTER> or selecting <F3> a sec- ond time. COMMAND SUMMARY 4-36 <a> arc-draws an arc using cursor position as start and end. As with the circle, the current cursor position is the center of the arc. The second position is the radius and one end of the arc. The third position is the other end of the arc. Arcs are always drawn counterclockwise. <A> draws arc with lines from center to end points (pie shaped). Use it exactly like <a>rc. Arcs are easier to draw in color because a dot cor- responding the cursor position is visible. COMMAND SUMMARY 4-37 <e> ellipse-draws a full ellipse. Use as with circle, but use up and right arrow to properly shape ellipse before hitting a <ENTER>. F3 |1 Creates ellipse e |1 RIGHT |3 UP |2 ENTER |2 The width of an ellipse is controlled with <w>idth from the Cursor Mode. As with circles there is effectively no limit on the width an ellipse can have. <Ctrl-e> draws the center line for an ellipse. Use just like <Ctrl-c>. COMMAND SUMMARY 4-38 <f> fillet or round for 90 degree corners. Start with the cursor at the corner. After selecting <F3 f> move at a 45 degree angle towards what will be the center of the fillet/round. F2 |1 Creates rectangle with two r |1 rounded corners. PGDN |7 ENTER |2 F3 |1 f |1 HOME |2 ENTER |2 RIGHT |2 UP |5 F3 |1 f |1 END |2 ENTER |2 COMMAND SUMMARY 4-39 <r> rose curves inscribed in circle. The circle is displayed allowing you to adjust the size with the Cursor Keys. Use <Enter> when the size is correct. Enter number of leaves. As with most functions the color of the resulting rose is set by <F10> while the inscribing circle size is set. <s> spiral from center outward. Move only a small distance from the center point to leave room for multiple arms if so desired. An interesting special effect can be obtained while the spiral is being drawn by holding down the <F10> key. This effect can not be recorded in a macro. <t> trig(sine)-produces sine curve. Set desired amplitude and period with cursor keys. Don't move the cursor too quickly when using <t> because it is slow. b-spline curves can be created by entering a number of points and letting the program draw a smooth curve between the entered points using a B-Spline routine. Use <ENTER> to mark the points or <Backspace> to back up and remove entered points. When all points are entered select a Function Key <F1-F8> to stop editing and to draw curve. <x> allows direct coordinate entry. Enter the scaled x and y coordinates. The cursor will jump to the new point. <n> or </> or < > or <Esc> exits function. COMMAND SUMMARY 4-40 F4 Shade & Fade <l> lightly shades enclosed area. <m> medium shading of enclosed area. <d> dark/heavy shading of enclosed area. The shade densities match those of <F2 s>hade. Use <F10> to determine color of shading. If area to be shaded is complex, it may require several tries to completely shade. COMMAND SUMMARY 4-41 <s> Spray paints area. Use on painted circle to give a 3-D effect. Affects active color only. First draw item and paint with <F5>. Current cursor location sets the position of light source (generally on the object). Next mark any corner of box containing object and select <F4> again. Mark opposite corner of box and select <F4> to spray paint. <Alt-s> as above but effects all colors. Set screen aspect ratio to 0 to shade columns. Spray paint works by looking for the foreground colors and replacing them with the background color. The setting of the ackground is thus very important. Spray painting is normally set to shade circular objects. To shade other objects you may want to adjust the spray pattern using the screen aspect ratio. Set the a$pect ratio to zero for columns. Remember to return the aspect ratio to its normal value after spray painting is complete. COMMAND SUMMARY 4-42 <f> fades enclosed area with color set by ackground. Fading is done on a pixel by pixel basis and is therefore somewhat slow. <Alt-f> fades all colors to color set by ackground. <x> allows direct coordinate entry. Enter the scaled x and y coordinates. The cursor will jump to the new point. <n> or </> or < > or <Esc> exits function. COMMAND SUMMARY 4-43 F5 Paint & Pattern paints the enclosed area with the specified fill color. You must also specify the border color by number. Gaps in the area to be painted will allow the paint to leak out. SHFT-F10 |1 Creates blue ellipse painted F3 |1 blue. e |1 RIGHT |3 UP |2 ENTER |2 C |1 F5 |1 p |1 1 |2 ENTER |1 paint-same as only remains active until next function is selected. Use <ENTER> to paint next area. <Alt-p> paints enclosed area with one of 29 color combinations. Use </> to select color set. The second color set, when used with the appropri- ate palette, provides 16 distinct colors on a composite monitor. The and <Alt-p> work differently and thus the ultimate result may be different. You may want to experiment with each to get the desired effect. COMMAND SUMMARY 4-44 background(*C*)-sets the color of the entire screen. 32 colors are available: 0-Black 8-Dark Gray 1-Blue 9-Light Blue 2-Green 10-Light Green 3-Cyan 11-Light Cyan 4-Red 12-Light Red 5-Magenta 13-Light Magenta 6-Brown 14-Yellow 7-Light Gray 15-White Select the color of the background by using the <Space Bar>. Fix the color with <ENTER>. The second set of 16 is similar, but with different intensity. <c> color (*C*)-sets the active color palette. col- or-turns on color and toggles it in high reso- lution. <C> (*C*)-selects unichrome palette ( sets uni- chrome color). Selects background color active in high resolution. <Alt-c> toggles multicolor mode in high resolution on a composite monitor. Colors are obtained by combining various dot patterns. Take a look at some of the pattern screens while in this mode to see a few of the possibilities. COMMAND SUMMARY 4-45 <m> modifies color (as set with <F10>) of object to one of 29 color combinations. <M> modifies color (as set with <F10>) of screen to one of 29 color combinations. <Ctrl-m> modifies one of 29 colors of screen to another one of 29 color combinations. <Alt-m> modifies one of 29 colors of object to another one of 29 color combinations. Modify searches for the desired color and replaces it with the new color. If the new color is zero then the color being searched for is erased. COMMAND SUMMARY 4-46 <f> fills area with one of 64 patterns. In order to properly fill an area it must be fully enclosed just as with paint or the fill will leak out. The basic 64 patterns can be modified as desired using <F7 o> to load the file KD- PTRN.PIC into one of the screens and then changing the desired pattern(s). Be sure to save the patterns with <F7 C>. <Alt-f> fills area with pattern from user specified file. File must have a PIC extension. Library Disk #2 contains 640+ patterns for inclusion in your drawings. Once a particular file has been called it is remembered and used as the default for <f>. While viewing the pattern screen it is possible to change that color combinations of the pattern screens using <v>, <V>, and <Ctrl-v> to perform a reverse video using the conventions of F1 Modifications. <S>hift is also available while viewing the pattern screen. These four com- mands effectively increase the number of pat- terns by a factor of 12, thus each 64 patterns on a screen are actually 768 patterns. 640 patterns are supplied with PC-KEY-DRAW version 3.30 making for a total of 7680 effective pat- terns. If this is not enough you can always create your own. COMMAND SUMMARY 4-47 <s> strips (*C*) all colors on screen except to one set with <F10>. This can be useful for produc- ing color viewgraphs without a color printer as discussed in Appendix F. It can also be used to turn all of the foreground colors to the same color by setting the desired color with <Alt-F10> and then setting <F10> to the back- ground color (0). <S> shifts (*C*) screen foreground colors by one. The background color is not effected. Thus color 1 becomes 2, color 2 becomes 3, and color 3 becomes 1. <x> allows direct coordinate entry. Enter the scaled x and y coordinates. The cursor will jump to the new point. <n> or </> or < > or <Esc> exits function. COMMAND SUMMARY 4-48 F6 Draw & Text Line width and dot size can be set in the CURSOR MODE with a <w>idth. All functions under <F6> except text, must be ended by entering <F6> as second time and selecting <e> or <E>. <d> dot-places dot at cursor location. An <ENTER> will mark dot and added it to the vector array. <D> continues vector array from last point entered. <l> line-connects cursor points with a line and adds it to the vector array. A <ENTER> will mark next point and continue drawing. All points must be marked with an <ENTER> or they will not be saved. Select <F6> a second time and <e> or <E> to end line drawing. You can temporarily suspend line drawing with a <Space Bar> and continue it again with the an <ENTER>. <Back Space> backs up one point. <L> continues vector array from last point entered. COMMAND SUMMARY 4-49 parallel-draws parallel lines and adds it to the vector array. Mark the first point of the first line, the cursor will be left behind. Mark the second end point of the first line with <ENTER>. Move to the second end point of the each subsequent lines that you want and select <ENTER>. continues vector array from last point entered. <s> spoke-draws lines from common center point and adds it to the vector array. Spoke works very similar to arallel. <S> continues vector array from last point entered. COMMAND SUMMARY 4-50 <e> exit-ends current mode. Required after any of the above. <E> ends current mode and saves line drawing to disk using user specified name. These are saved as vectors and are ideal for commonly used sym- bols. The default extension is VCT. <Ctrl-e> allows the last drawn vector symbol to be saved to disk, even after other operations. Line, dot, parallel line, and spoke line must be ended. When the line is ended the screen is first refreshed and then the line redrawn. COMMAND SUMMARY 4-51 <o> old line drawing from disk. A single drive let- ter will display appropriate files on disk. Must specify rotation angle(any angle) and scale factor. When asked for the scale factor select </> to enter the zoom factor instead. <O> old, last drawing selected from disk or last vector drawn. Allows alternate rotation and scale. COMMAND SUMMARY 4-52 <c> cursor-draws continuous lines as the cursor is moved. Use this function for freehand drawing with the cursor or with a mouse. Line drawing can be suspended by hitting a <Space Bar> (the second mouse button) and restarted with the <ENTER> key. Unlike most other drawing operations in PC-KEY- DRAW, <c>ursor drawing is absolute and once down is not redrawn on ending. As a result the displayed grid and visual layers are not avail- able as they would otherwise become part of the drawing. Cursor drawing must be ended to actually save it to the current screen. COMMAND SUMMARY 4-53 <t> text-enters text at cursor location. (Location when <F6 t> is selected) The size of the text is determined by the mode the program is in. In high resolution 80 column text is available, while in medium resolution only 40 column text is available. The text will not be exactly at the cursor location, but will be placed as near as possible on the standard text screen. <T> text-allows text to be <c>entered or justified <r>ight or <l>eft. <T> also allows text to scroll up (good for macro slide shows), to be printed vertically p or <d>own, allows <a> ASCII file import to the current line the cursor is on, filling to the end of the file or end of the screen and <A> provides continuous inputof text until <Esc> is selected. The same conventions of text size for <t> apply to <T>. Scrolling takes place when a capital letter is used for a particular command. <Ctrl-t> text-is copied into <F7> so it can be moved to position required. As with <t> and <T> the text size is determined by the mode. <Ctrl-t> is useful for a number of operations where it is necessary to exactly place the text. COMMAND SUMMARY 4-54 <Alt-t> text-allows use of alternate fonts as stored on disk. Font file default extension is FNT and can be created with any and all program features and saved with <F7 C>. The program disk contains two font files, KD-FONT1.FNT and KD-FONT2.FNT. Library Disk #3 contains addi- tional font files. See Appendix H. Font text is brought into animation so that it can be place as desired. Use <x> to left justify by setting the x coordinate to zero, use <C>enter to center the text on the screen. To fix the text use <F7 M>. <x> allows direct coordinate entry. Enter the scaled x and y coordinates. The cursor will jump to the new point. <n> or </> or < > or <Esc> exits function. COMMAND SUMMARY 4-55 F7 Copy & Move <e> erases the enclosed area and copies it for use with <a>, <s>, <r>, and/or <m>. The erased area is held in the F7 screen buffer until replaced with a subsequent operation using F7. If after erasing an area you decide to save it to disk, use <Ctrl-PgDn> until you reach Screen F7 and save with <F8 s>ave. The file will be saved as a PIC file. <E> erase and animate-allows an area to be picked up and moved quickly. After erasing the area the screen is updated. <F7 E> is equivalent to <F7 e ENTER F7 a>. <Ctrl-e> erases area enclosed in circle. The erased area is not saved and is therefore lost. <Alt-e> erases enclosed area but does not copy it to the F7 screen buffer. Any object in the buffer is not effected. COMMAND SUMMARY 4-56 <c> copies area to be moved, but does not erase it. The area is saved in the F7 screen buffer. <C> copies the portion of the screen to disk for later use. No extension on the user supplied name creates a file that can be retrieved with <F7 o>. A FIG extension saves portion of screen in an ASCII format. A BAS extension will save the screen as a basic subroutine for use in user written programs. A FNT saves the object as part of a font library for use with <F6 Alt-t>. <Ctrl-c> copies the same size object as previously copied without remarking. COMMAND SUMMARY 4-57 <o> retrieves drawings saved with <C>. The object is brought into animation and can be positioned as desired. If the object looks jumbled, it may be because it is partially off the right side of the screen. Try moving to the left to see the object. <O> retrieves drawings saved with <C> and immedi- ately places them on the screen as would occur with <F7 Alt-m>, thus replace anything under the rectangle defining the object. <a> animate allows a previously copied or erased area to be moved around the screen with the cursor. As the object is moved vertically off the screen it will slowly disappear until the cursor wraps. As the object is moved horizon- tally off the screen it will distort until wrapping occurs. COMMAND SUMMARY 4-58 <m>, <M>, <Ctrl-m> and <Alt-m> move area previously erased or copied to lower right of cursor, each with a different syntax. (different result). The sample demo provides a good example of the different results obtained with the four syn- taxes of move. Basically <m> XORs the copied area with what is on the screen. If a copied object is XORed twice the original screen image is restored intact. <M> performs an OR with the object and screen, thus superimposing the copied image onto the screen. <Alt-m> uses the PSET action to replace a portion of the screen with the copied image. <Ctrl-M> uses AND to transfer an image only if an image already exists. <s>, <S>, <Ctrl-s> and <Alt-s> smear the copied object with each step of the cursor using dif- ferent syntax. Use this as a paint brush. Copied size determine number of bristles in brush. The syntax of smear is the same as move. <r>, <R>, Ctrl-r> and <Alt-r> replicates object with each cursor step. The syntax of replicate is the same as move and smear. COMMAND SUMMARY 4-59 <l> inserts a horizontal line at the cursor posi- tion. The number of lines inserted is deter- mined by the cursor speed setting. <Alt-l> deletes a horizontal line at the cursor position. The number of lines deleted is deter- mined by the current cursor speed setting (<F10>). <x> allows direct coordinate entry. Enter the scaled x and y coordinates. The cursor will jump to the new point. <n> or </> or < > or <Esc> exits function. Note that when a very large or complex object is rotated or zoomed using <F1>, the last copied area maybe lost. The last screen copied or erased can be view and further manipulated by selecting <Ctrl-End> <Ctrl-PgDn>. It is pos- sible to copy the entire screen as follows. Alt-1 |1 Jump to Top-Left-Corner (0,0) F7 |1 c |1 Start copy HOME |1 Move to Bottom-Right-Corner ENTER |1 Complete Copy COMMAND SUMMARY 4-60 F8 Files & Exit <d> directory of selected disk. Any disk drive A-Z can be accessed. The entire directory is shown. Partial directories are available any time you are asked for a FILE NAME by entering a single drive letter only, then <ENTER>. Use the SUBST command with DOS 3* to replace path names with single drive letters. PC-KEY-DRAW does not otherwise recognize paths. <s> saves the current drawing - must be room on disk. For best results save drawings on B:. Two files will be saved. The first is the screen file saved with a SCN extension. The second is the data file for scale information. Multiple pages/layers must be saved independently if they are to be used again. A single drive let- ter displays the screen files on that drive. COMMAND SUMMARY 4-61 <o> old-retrieves a stored drawing from disk Screens previously created with this program should have an associated data file with scale information. A directory of files available for loading are available by entering a single drive letter at the request for FILE NAME. <O> old-displays screen files on disk and loads then for sequential display using <PgDn>. The ause command can be used to temporarily pause if the <O> option is used as part of a key macro. <Ctrl-o> template-allows a template screen to be called up. Disables updating of disk. Retrieve working screen with <F8> <w> or <W>. Screen 2 can be used for a template screen without invoking template. This keeps your template files handy. <Alt-o> displays screen files using one of five display methods. This is primarily for use with slide show macros as a special effect. The files are first loaded into the memory space normally reserved for Screen F7 so anything in that buffer will be lost. The five display types are: 1 Fade In 2 Pull Down 3 Pull Up 4 Pull Right 5 Pull Left COMMAND SUMMARY 4-62 <f> fresh-clears screen and starts again. If the current drawing has not been saved on disk it will be lost. <F> fresh-clears screen and layers or pages from workspace disk. Be sure you have saved any and all of the pages and layers that you want for later use or they will be lost. <F>resh will delete all files on the workspace disk named PAGE.??? so do not name other files by that name or they will be lost. COMMAND SUMMARY 4-63 prints graphics screen on line printer #1. The last screen title is displayed and you are asked if it is OK. <y>es will print the title with the screen. <n>o allows you to enter a new title on the prompt line. Most printers require that you load GRAPHICS.COM (from your DOS disk, see DOS manual for more information) to print properly. <Ctrl-p> zoom prints partial screen. Enclose area to be printed in box. Zoom prints entire screen. With partial and full screen zoom printing you must specify the characters to use and one of three sizes.(1 is the smallest and 3 is the largest) COMMAND SUMMARY 4-64 <w> restores old workspace #1 to any screen along with scale information saved with the work- space. The drive for workspace is set as part of the general program configuration and should be a RAM disk if available. <W> restores old workspace #2 to any screen. The two workspaces are stored as screen files with an SCN extension. If <O>ld sequential is used on a disk with a workspace, the workspace will be included in the sequential file display. Use workspace as a quick save method (see Update) or as a place to hold a drawing while you make temporary changes to it. COMMAND SUMMARY 4-65 <k> kills a file on the disk. User must specify full name including drive. This works the same as the DOS DEL function. For wide card deletes use ? instead of *. To delete all files with a SCN extension on drive B: enter the following name when prompted: B:????????.SCN <K> renames a file on disk. <e> exits program completely and returns to DOS. Since PC-KEY-DRAW offers so many different ways of saving a drawing, it is up to you to be sure you have properly saved what you were working on and in the form you wanted. <e>xit does ask you to confirm your desire to exit. <x> allows direct coordinate entry. Enter the scaled x and y coordinates. The cursor will jump to the new point. <n> or </> or < > or <Esc> exits function. COMMAND SUMMARY 4-66 Zoom Printing with F8: Print sizes range from 1 to 41 Size 1 corresponds to 17 cpi Size 2 corresponds to 12 cpi Size 3 corresponds to 10 cpi Some printers do not support all three character pitches and will not be available for use. Size 4 through 41 are multiples of the first three sizes. Some experimentation maybe necessary to find the correct size to print with. Start small!!!! 1X 2X 3X 4X 5X 6X 7X 8X etc. 17 CPI 1 4 7 10 13 16 19 22 12 CPI 2 5 8 11 14 17 20 23 10 CPI 3 6 9 12 15 18 21 24 Several printer configurations have been include on the disk. Any printer can be configured to work with the zoom printing option. To select a printer or to configure a printer select <Ctrl-s> from the CURSOR MODE. Set desired printer number and the screen will switch to the configure printer sec- tion. Select one of the available printers or using your printers owners manual enter in the configura- tion for your printer. Note that printer number one "1" is reserved for an Okidata 92. Please send any printer configurations so that oth- ers can use them. See LIBRARIES. COMMAND SUMMARY 4-67 F9 Speed <F9> Cursor speed is controlled with <F9>, <+>, and <->. <F9> toggles between setting the cursor speed to 1 and to the last speed set with the <+> and <-> keys. This allows rapid movement or fine movement. <Shft-F9> forces the cursor speed to 1. This is intended for use with a key macro. F10 Color <F10> controls the color that many of the functions work with. Lines, rectangles, circles etc. will be drawn to the color set by <F10>. Other com- mands such as paint, spray paint, rotate, etc. use the color to work with. If a particular function does not appear to work, it may be that the color was not set correctly. <Shft-F10> forces the color to color 1. This com- mand can be useful in creating certain types of key macros. <Alt-F10> temporarily sets the background color used by the program. The color in use is dis- played in column 40 of the screen. COMMAND SUMMARY 4-68
