- Hi,
-
- I've experimented a little with the PS-Level II colorspaces.
- Normal drawing is OK (once the color space is set up, which
- takes a while).
-
- However, images are incredibly slow: Over five seconds for
- a 256x256 image. This comes out to about 75 microseconds
- per pixel! What are they doing, interpreting the PostScript
- procedures for each pixel? I thought there would be lookup
- tables, but apparently not.
-
- Has anybody tried this, and possibly gotten better results?
-
- Grateful for any info,
-
- Marcel
