Pixel by Pixel compare

[dbdg]

Hi Guys, question from one of my mates.

Looking for a peice of software that compares two or more images pixel by pixel to see if they are same. I suppose the sort of test that appear in the Pro version of CrapMark 2003 etc.

Any ideas??

Well, Paint Shop Pro has Image Arithmetic functions..

You can use Photoshop to get the difference of two layers. Not hard.

Yeah but what if you have a large number of images that you want to do this too.

What's the format of those images, you can easely compare tiffs.

BMP's at the moment but just as easily tiff, format isn't an issue, he just wants to be be able to quickly compare a batch.

BMPs are even easier. just go to the command prompt and type:

fc /b file1 file2

This will compare file1 with file2. You can of course add paths in front of the files.

EDIT: You can actually do this with any file, since it is a binary comparison. But it's most transparent for BMPs, as that is a rather simple format.

Cheers Dude, works like a charm.

Or you can use Total Commander.
Files -> Compare by content (important: check Binary).

Can be even faster.
