I want to scan an area of 50 x 50 mm at 4800 dpi in full-colour 16 bits.
This should be possible with Canon Lide 210 but my system won't.
I confirmed the specifications of the scanner that it should indeed be
optically capable of 4800dpi.
I have one of these scanners and I just tried it out. Indeed, in Sane
1.0.28, 4800dpi is not currently supported and scanning is dropped down
to 2400dpi.
Looking at the code of the Genesys backend, I see this:
model.resolutions = {
{
{ ScanMethod::FLATBED },
// BUG: 4800 resolution crashes
{ /*4800,*/ 2400, 1200, 600, /* 400,*/ 300, 150, 100, 75 },
{ /*4800,*/ 2400, 1200, 600, /* 400,*/ 300, 150, 100, 75 },
}
};
That suggests that it should be supported but is buggy at the moment.
If I have time this weekend, I will look into it.
Cheers,
Ralph
