[sane-devel] snapscan os/2 mods
Sun, 05 Aug 2001 11:46:00 +0200
I've just uploaded the modifications that I've made to the snapscan
source to get it to work with OS/2.
A few points about the changes. I've added an extra stub file with empty
function definitions for USB. That could be meged into the existing USB
source, if appropriate #ifdefs are used.
The other changes impact the reading of the calibration data. The
release 1.0.5 code tries to read 244K in one go, whilst the OS/2 buffer
is only 32K. To get around this, I hard coded a smaller buffer, which I
read 30K at a time, 8 times, each time copying the part that was read
into the main buffer.
Clearly it'll take a bit more effort to get that to work (probably again
The resulting binary generally works OK, but I've had some troubles
reading the images that it generates. xv seems to accept them, but not
the shareware OS/2 application I use - this applies both to tiff and
pnm. I'll look into this when I have some more time.

If more is better, are double standards better than single ones?
