A front end question ! As far as I understand from the SANE spec, a backend may send colour image data as either an R, G & B sample per pixel, what TWAIN refers to as chunky, or as three separate images, one of R, one of G and one of B, what TWAIN refers to as planar.
Is there any way of forcing a backend to go one way or another ? And secondly, is there any way of determining if the data will be planar or chunky before calling sane_start() ? Cheers Guy
