Using this program, you can compare images files, and print contact sheets. The program works on all PICT and JPEG files, including Quicktime compressed pictures. Version 1.5 and up require at least Quicktime 3.0.
PiXcompare also identifies two pictures if
* one of them is grayscale
* they don't have the same size / aspect ratio
* they have a different intensity
* they have a different pixel-depth
* and when one of them is blurred
PiXcompare works best on digital photos.
