- Here are some ideas on the refresh buffer that I want to throw out
- onto the table. We have to keep in mind the current max limit on the
- refresh buffer is currently at 768K, and will possibly go as high as
- 1.2MB for the newer 1280x1024 images that the XGA standard will support.
- I would like to get your input; I know Archie has already done a lot of
- work with it.
-
- o Store refresh buffer into a disk file (current implementation).
-
- o Store refresh buffer into expanded/extended memory. Using the SWAP
- code as a baseline, I think that this is feasible. Archie, you
- used the SWAP code, so what do you think? If there is not enough
- expanded or extended memory, then we can always go back to putting
- the refresh buffer in a file.
-
- o Compress refresh buffer before storing in memory. Maybe DECOMP.C
- can be used, or another algorithm, but it should be as fast as
- possible, and give at least a 3:1 compression ratio. Of course,
- any operations done on the image will be done as the image is
- decompressed on-the-fly, so we would have to be able do access the
- image on a line-by-line basis, and possibly even pixel-by-pixel.
-
- o Split the refresh buffer between available memory and a disk file.
-
- o Any combination of the above.
