-
- In my mind, there are two separate cases that should be handled.
-
- 1: If one would like small pictures in the document, these would
- have to be uncompressed bitmaps, since waiting for a single
- page to show is unacceptable. These would be contained within
- the document for maximum speed in my view.
-
- 2: Larger pictures with more colors would be better off in
- an external picture file, and handled by an external
- viewing program. For example one could have a system
- variable called GIF_VIWER and another called JPEG_VIEWER
- containing the path for the preferred viewing program
- on each system. Then it's up to each user to set these
- to their program of choice.
-
-
- This has several advantages.
-
- - Since no graphics compression standard is completely
- flawless each picture could use the optimum standard.
-
- - You can always use the fastest decompression program
- for the standard.
-
- - The documents won't grow so large.
-
- - Only bitmaps will have to be decoded by the guide-
- program itself.
-
- - If new and better compression standards evolve,
- we won't be in a corner.
-
- So, there. Now I got that off my mind...
