IM.js checks all your images using canvas pixel by pixel in record time.
One month ago I needed to test the rendering url results in different browsers, and make it automatic and use it with Jenkins (C.I. server).
I found some desktop tools to compare images but that are not for use with Jenkins.
I want to check different images seeking for different pixel info, because different compression returns different image file info.
Compare images pixel by pixel is a slow and heavy work to our computer!
IM.js has come to solve this problem!
- Compare images pixel by pixel in a fast and not blocking way.
- Be used in environments to automatize testing of web url snapshots.
- Be framework agnostic.
