|

* directly.
|
|
|
|
*
|
|
|
|
* The scanner sends the colors by rasters (B then G then R), whereas
|
|
|
|
* sane is waiting for a group of 3 bytes per color. To make things
|
|
|
|
* funnier, the rasters are shifted. As a result, color planes appear to be shifted be a few pixels.
|
|
|
|
*
|
|
|
|
* The order of the color is dependant on each scanners. Also the same
|
|
|
|
* scanner can change the order depending on the resolution.
|
|
|
|
*
|
|
|
|
* For instance, the VM6586 at 300dpi has a color shift of 2 lines. The rasters sent are:
|
|
|
|
* starts with two blue rasters - BB,
|
|
|
|
* then red in added - BRBR
|
|
|
|
* then green - BRG ... (most of the picture)
|
|
|
|
* then blue is removed - RGRG
|
|
|
|
* and finaly only green stays - GG
|
|
|
|
*
|
|
|
|
* Overall there is the same number of RGB rasters.
|
|
|
|
* The VM3575 is a variant (when factor_x is 0). It does not keep the same order,
|
|
|
|
* but reverses it, eg:
|
|
|
|
* BB RBRB GRB... GRGR GG
|
|
|
|
* (ie it adds the new color in front of the previous one, instead of after).
|
|
|
|
*
|
|
|
|
* So this function reorders all that mess. It gets the input from
|
|
|
|
* dev->buffer and write the output in dev->image. size_in the the
|
|
|
|
* length of the valid data in dev->buffer. */
