Is the a way to make hp-scan or scanimage to automatically select de right area to scan?

Question

I'm trying to make an non network scanner to work with linux running via command line and hiding it with php/html. The commands to scan hp-scan and scanimage are working well but they don't automatically select the non blank are to scan. For example if I scan a business card (85mm x 58mm) it scans the entire scanner area. Does sane have an utility to fix that? I am using ubuntu 13 and mint 16.

scanimage --mode Color --resolution 100 --progress --compression JPEG --jpeg-quality 80 --format=tiff | convert tiff:- teste.jpg

Solution

I am also using X*Y coordinates when using scanimage. For your use case, I would have used the following command:

scanimage --progress  --format tiff --mode Color --resolution 300 -l 0mm -t 0mm -x 85mm -y 58mm | convert - -resize 50% -quality 75 teste.jpg

which commands are you using?

This is one: sudo scanimage -p --mode=Color --compression=JPEG --jpeg-quality=80 --resolution=100 --format=tiff | convert tiff:- test.jpg

where did you find the "--jpeg-quality" option document? My man page does not list it!

Thank you. I've already set sane as server for remote scan.
