- Let me suggest PICT format for maps and various graphics as a good choice.
- Among its advantages are
-
- (a) it is standard on all Macs, and available on MSWindows.
-
- (b) it is an editable format with the right software
- (again common to Macs and available on MSWindows). That will
- be very important to biologists who want to fetch Flybase maps
- and do something with them. This option isn't available for GIF
- or Postscript.
-
- (c) it is a vector method like Postscript, and retains unlimited
- resolution. Printed PICT maps are indistiguishable from printed
- Postscript maps.
-
- (d) it is a binary, small format compared to Postscript. Expect
- PICT format files to be 1/10 the size of Postscript.
-
- (e) it can include bitmap images, and includes compression of these,
- though not as great as GIF format.
-
- (f) it is not encumbered by patent restrictions as the GIF compression
- algorithm is.
-
- (e) the GopherPup network browser will display
- PICT format, on XWindows and MSWIndows as well as mac, and
- can easily include network links as in Mosaic GIFs. I've timed
- the access of this low-weight PICT versus GIF for maps, and
- using PICT is about 5 times faster (as well as having the above
- advantages (b) and (c) that GIF lacks).
-
- PICT format is fully defined and an open, well known standard graphic
- format. You can find specifications in various "Inside Macintosh" books
- available at local bookstores. I can also help you write any PICT
- drawing routines. It will look similar to your postscript drawing
- methods, but substitute various keywords here and there.
-
- The only advantage I can see to having GIF-format maps as well is that
- is the Mosaic-class network browsers know how to display.
