[sane-devel] test backend: 1 bit RGB data for grid pattern

2002-09-25 Thread abel deuring
Hi all, while playing with the test backend, I noticed that the scan data produced for the grid pattern in 1 bit RGB mode differs from the output for 1 bit grayscale mode. The data for gray scale mode is like: ... 00 00 00 0f ff ff ff f0 00 00 00 ... while the data for 1 bit RGB mode
