I have tried the official Canon Scanner Driver for Windows have the feature of auto cropping an image (to be more precise a photograph), what this software do that whenever you scan an photograph or group of photographs it just crop the image accurately and then save it, just like we do with manually in GIMP or other image cropping software. Is there is alternative software in linux which have similar functioning.

I have tried Imagemagick (trim/fuzz) but the scanner image background is not such white as expected by the software.

You should also try reading the documentation on Imagemagick, which would tell you that you can set the background image to be whatever color you want. Even covered on their forums:

https://legacy.imagemagick.org/disco...ic.php?t=34661
https://imagemagick.org/discourse-se...ic.php?t=36443

...and this sounds familiar, where you asked about trimming things with images:

Since you seem to have a lot of problems with your printers, scanners, and now software (and everything seems to work for you in Windows), why aren't you using Windows to get your work done???

Hey jiteshpandey,

To build on TB0ne's response, scanning in Linux can be a challenge. Device support really depends on the internal chips of any given scanner. For example, certain models of Canon scanners are supported but others, even of the same product line, are not, because the chips they use are different.

Also, what we often refer to as "scanner drivers", are in reality, applications (programs) in and of themselves. So for example, even if your scanner IS supported by Linux, the Linux "driver" may not offer the same options as the Windows version.

From experience, I can say that HP (Hewlett Packard) scanners are fairly well supported by Linux, and you are more likely to find similar functionality.

In the end, you may (or not) have to supplement driver functionality in Linux with post-scanning use of imaging applications like Gimp, Rawtherapee and others.

Hope this helps - Cheers.
