Description Author

This class can be used to compare two images to check if they are identical.

It can traverse two given images in the PNG format of the same size to determine which pixels are different.

The class can circle or fill the areas that are different with a given color. The resulting image is displayed as the current output in the PNG format.

Number 8		 Sometimes it is necessary to evaluate whether two images are identical in order to figure if one may be at least a partial copy of the other.

This class provides a pure PHP solution to compare two images and shows graphically how similar the images can be.
