NAME


pngcomp - PNG (Portable Network Graphics) comparison tool

SYNOPSIS


pngcomp [-vVh] image1.png image2.png

DESCRIPTION


pngcomp gives some basic statistics about the difference between two images. It was
created as a measure of various color quantization methods.

OPTIONS


-v Verbose, does nothing as yet.

-V Version, prints version information.

-h Help, prints this message.

NOTES


The stats created by this program are purely based on the Euclidean distance in RGBA space
between the pixels of the images. Later versions will include different measures such as
CIE color space measurements and filters for perception models.

The error calculation used reflects the perceived quality of images only roughly.

To determine what image is better nothing can surpass having a look for yourself!
