I found no image compression support is added in SANE. When scanning with high
resolutions such 600 x 600 dpi and uses color scan, the result image will be
very large!
So many scanners support compress transfer:scanner compress the image data
and transfer compressed data to driver. In SANE the images transfered between
backend and frontend are strict limited.I think it' better if SANE add some
file transfer type like TWAIN.

Most scanners do not support compression anyway. Such features are
only found in 5000 EUR and above devices. If you just want to save
files in a compressed format just use a decent application such as
xsane and not the example programs such as xscanimage ,-)
