- The issue, one I'd like to see addresses about "improved WYSIWYG" is
- that Apple's "one inch of screen equals one inch of output" is based
- on 72dpi. This may have been chosen because of 72points=1 inch but
- has no necessary relationship.
-
- Improving the DPI for WYSIWYG, though, is very difficult. Fonts
- could handle it if they were rendered from outlines, like with ATM
- and TrueType. Object graphics could handle it. Ask for a 2-inch
- circle and it will put down a 2-inch circle. But what of bitmaps?
- Icons? Etc. They would all appear shrunken since they store a series
- of a distinct number of dots only. If a 64-pixel icon is shown on a
- normal Mac screen, it appears to be almost an inch in length. If
- it's shown on a 120dpi monitor from Sigma, it looks much smaller.
-
- If you improve the WYSIWYG dpi, you can't fix that problem without
- redrawing all the bitmapped graphics (yikes!). Unless, that is, you
- go to 144dpi. That would provide backward compatibility. (Identify
- it as a first generation bitmap and draw it with clumps of 4 pixels
- for every one). It would also make the Mac sharper than the 91 (I
- think) dpi next. Windows WYSIWYG dpi appears to be better than 80 as
- well. Of course, you'd need a 144dpi monitor, which doesn't really
- exist, but ....
