Overview

Scanpic allows you to scan images of a specified size from the command line without use of a GUI and without needing to crop the image afterward. I wrote this script when I had hundreds of old pics of various sizes to scan, and I didn’t want to have to crop them all individually.

By default, scanpic will scan the entire size of the scanbed. If a pic size is specified with “–opt” or with “–dims”, it will can only the region specified, which speeds up scanning.

Examples:

# scan a grayscale 8.5x11" page scanpic --opt page myscan.jpg # scan a 24bit color 8.5x11" page scanpic --opt page,col myscan.jpg # scan a B&W 8.5x11" page, rotate 90 degrees, and reduce to 1024x768 scanpic --opt page,bw --rotate 90 --size 1024x768 myscan.jpg # scan a 3.5x5inch vertical color photo at 300dpi scanpic --opt 3.5x5v,col --res 300 myscan.jpg

By default, scanpic uses very high quality settings for the scan, which produces a relatively large file, but these can be reduced using the command line arguments, or by editing the User Defaults section at the top of the script.

scanpic will attempt to determine the device name of your scanner. You can also set the device name in the User Defaults section (which will also speed up scanning). You can lookup the scanner device using:

scanimage --list device `brother2:bus4;dev1' is a Brother MFC-7420 USB scanner

In the above example, you would use “brother2″ as the device name.

Some scanners will not scan to the very edge of the scanbed. To compensate for this, you can shift the photo away from the very corner and specify an offset to scanpic. On my Brother MFC-7420, I taped an L-shaped piece of cardboard into the corner of the scanbed to create an offset, then determined that the offset I needed in scanpic was 12×4.5 (mm). If you notice the photo is shifted out of place, you may need to use a similar method to move the photo away from the corner of the scanbed, then scan a few times experimenting with offsets. Once you get it calibrated, scanning almost perfectly cropped photos is very fast.
