These slides are intended for use in product demonstrations. I started by adding 14 layers to the standard layer set of PC-CAPS and PC- CARDS. Each of these layers was then assigned a different color and named after that color. The layers (and their color numbers) are: GREEN 1 RED 2 YELLOW 3 BLUE 4 CYAN 5 MAGENT 6 GRAY 7 LGREEN 8 ----| LRED 9 | LYELLW 10 | LBLUE 11 | these are the "LIGHT" colors LCYAN 12 | LMAGEN 13 | LGRAY 14 ----| The best color combinations seem to YELLOW-BLUE, RED-YELLOW, BLUE-CYAN. The effect of RED-WHITE-BLUE can be achieved with RED-CYAN-BLUE. The "light" colors (e.g. light-yellow) can be used to de-emphasize one piece of text from other text which is the main color (e.g. yellow). A filled rectangle of a "light" color, overlaid with a normal colored text, can be used to create "block" diagrams and to emphasize a particular piece of text. PC-CAPS and PC-CARDS paint the layers in the following manner. When in DETAIL mode, any included parts or symbols are painted in their entirety one after the other. Next, all DRAWN items (lines, rectangles, etc.) are painted, followed by any WIRES. Colors within a symbol or part and drawn items (ie items created with the DRAW command) are painted in the same order that the first item of that color (on any layer) is encountered in the database. e.g. If the first item drawn on a blank screen is a RED rectangle, all RED items regardless of which layer they're on or when they were drawn, will be drawn before any items of any other color. If all red items are deleted at some later point and then a new red item is drawn, RED will acquire a new painting order relative to any previously drawn items. Wires are a special case in that they are drawn in the order they were entered, regardless of the the layer they are on. A trick that I have used to keep the colors in a consistent order is to draw on a default sheets (called INIT-PCB.PCB and INIT-SCH.SCH) that have the correct color layers and a small rectangle on each layer in both SYMBOL and DETAIL modes. These rectangles were drawn in the correct order and will (unless you delete them) preserve the color drawing order. A further idiosyncrasy of our software is that when items are MOVED, the system may temporarily change the order the layers are drawn; the REDRAW command will correct this situation. Furthermore, the color order isn't preserved when you are initially DRAWing items. You will have to choose another command (e.g. MOVE, COPY, SYS, etc.) and then REDRAW the screen to see the DRAWn items in their correct color order. The order in which the various colored layers are painted on the screen can have an effect on the appearance of the overall picture. For instance, a filled rectangle can either highlight a piece of text (if the rectangle is drawn first) or hide the text (if the text is drawn first). An interesting effect that can be applied to text is created by copying a piece of text at a 45 degree angle on very small increments (e.g. a 200 dbu height text copied on 2,2 dbu increments). The resulting text will appear to have thick and thin lines, as opposed to the uniform skinny lines of standard text. It will also look something like an "OLD-ENGLISH" font. This isn't entirely coincidental in that part of the distinctive look of calligraphic fonts is due to the varying line widths produced by a broad flat pen tip. The line width varys according to the direction of a stroke relative to the flat surface of the pen tip. Copying texts at 45 degree angles produces the same effect, because horizontal and vertical lines in a font appear broad, while 45 degree lines are either very broad or very thin. A further effect that can be applied to this wide text is to change the layers (and hence the colors) of some of the contiguous pieces of text. Because each color is drawn in a particular order, the upper layer will hide anything directly beneath it on a lower layer. This results in a 3-dimensional effect. The text will appear to be popping out of the screen at 45 degree angle in a direction from the background color to the foreground color. Therefore, depending on: 1. which 45 degree angle you copied your text, and 2. the relative positions of the background and foreground colors, the text will appear to be leaving the screen from either the UPPER-LEFT, UPPER-RIGHT, LOWER-LEFT, or LOWER-RIGHT. You must be careful if you have several pieces of multi-colored text on the screen, because each piece of text may appear to leave the screen at a different angle - which can be quite unsettling to see. If the screen is going to be placed above the heads of the audience (as at a trade show booth), then I recommend that you have the text leave the screen to either the LOWER-LEFT or LOWER-RIGHT. I prefer to copy my text to the UPPER-RIGHT, but have the foreground color to the LOWER-LEFT. When changing the layers of the text, it is easiest to use the CHANGE-LAYER-WINDOW command. Be aware that the lower boundary of a piece of text extends below the base line of capital letters. A short cut to use when creating the text is to initially write and copy the text in the background color. Then change to the foreground color and use the CHANGE-LAYER (non-window) command on the text. The software will change the text one copy at a time starting with the original piece of text, and continuing in the order they were copied. This short cut only works once; after that, you will need to use the CHANGE-LAYER-WINDOW command. Another item that I considered in creating these slides was the variation caused by the viewing them on different monitors. Each monitor has a different number of colors and pixels and a different aspect ratio. Our software provides a finite number of zoom levels. The difference in size between two consecutive zoom levels is proportional to the resolution of the monitor. The minimum window that can be viewed (zoom level #1) is also proportional to the resolution of the monitor. Therefore, the HR-25 monitor, which has higher resolution than the EGA, has larger increments between consecutive zoom levels and also has a larger window for zoom level #1. The minimum difference in size between two zoom levels can be as high as a factor of two for low zoom level numbers. A small "slide" or piece of text may be fine on one monitor but either too big or too small on another monitor. When viewing large items, the software can change the window size by much smaller factors (e.g. 1.05). By drawing all of my slides quite large, I was able to choose sizes that would just fill the screens (in one dimension or the other) of either monitor. Here are my suggestions (in DBU's) for different COMMON WINDOWS in which to create your slides: For a window that can be recalled on either monitor with the RCL command and see the entire COMMON WINDOW: EGA 6256w X 4488h HR25 6120w X 5336h COMMON WINDOW 6120w X 4480h For a window that will have the same full-screen height when viewed on either monitor with a VWIN command on the common-window: EGA 8563h X 6128w HR25 6992h X 6096w COMMON WINDOW 6990h X 6090w For a window that will have the same full-screen width when viewed on either monitor with a VWIN command on the common-window: EGA 7908h X 5714w HR25 7866h X 6858w COMMON WINDOW 7860h X 5710w A precautionary note is that PC-CAPS and PC-CARDS store the initial view of a schematic as a center point and a zoom number (see the PDIF manual for further detail). Since the zoom numbers of different monitors represent very different window sizes, an initial full-screen view of a schematic saved on a EGA will look very small when loaded on an HR25. The 10 stored views of a schematic, however, are specified as lower-left and upper-right corners of each view. These views when recalled (using the RCL command) will appear roughly similar on different monitors. I therefore recommend that you save the schematic while looking at a blank area of the screen and use the RCL command (or the VWIN) command to recall the view you want. For the slides I created, I decided to only support the EGA and HR-25 monitors. The CONOGRAPHIC and PGA monitors will probably work well, but the CGA monitor will have problems with some of the slides. Supporting the CGA monitor would have limited me to 4 colors and very big pieces of text. The viewports for the different monitors can be graphically viewed in VIEWPORT.SCH and VIEWPORT.PCB. Their sizes are approximately as follows: The EGA monitor has the following The HR-25 monitor has the following view-port sizes (approximately) view-port sizes (approximately) in PC-CARDS and PC-CAPS: in PC-CARDS and PC-CAPS: ZOOM # X (WIDTH) Y (HEIGHT) ZOOM # X (WIDTH) Y (HEIGHT) -------------------------------- ------------------------------------ 1. 112 80 1. 176 152 2. 140 100 2. 218 190 3. 188 136 3. 290 252 4. 284 202 4. 436 380 5. 568 406 5. 874 760 6. 1136 814 6. 1748 1520 7. 1704 1218 7. 2622 2280 8. 2272 1624 8. 3496 3040 9. 2834 2036 9 4380 3800 10. 3396 2446 10. 5240 4560 11. 3984 2856 11. 6120 5336 12. 4534 3258 12. 6992 6096 13. 5120 3672 13. 7866 6858 14. 5688 4066 14. 8750 7630 15. 6256 4488 15. 9592 8382 16. 6816 4894 16. 10496 9144 17. 7396 5282 17. 11322 9906 18. 7908 5714 18. 12236 10676 19. 8563 6128 19. 20. 9084 6510 20. 13984 12192 21. 9670 6912 21.
