- If I understand you correctly you are saying that (with the exception of
- Postscript devices where one can use PictComments to output a setlinewidth
- command) one must use bit maps to achieve 1 pixel wide lines on hi-res devices.
-
-
- If this is the case I can see the following drawbacks with this approach for
- the HP Paintjet:
-
- 1. Increased complexity - overriding the Standard Print Handler is something I
- would rather avoid.
- 2. Huge memory requirement for the bit map.
- 3. All dithering to produce simulated 256 or more colors from the 4 inkjet
- colors would be done by me? or Quickdraw? instead of by the Painjet driver.
- 4. The same would apply to the font substitution that that driver can apply.
-
- It seems that I have not flushed out anyone at Apple or MADA who has actually
- implemented a solution to this problem. Everyone else has just read the tech
- notes and the description of FracApp300.
