Sometimes you need to generate variants of the same image to present it in different colors.

PHP provides a good set of functions that you can use to manipulate images in any way you need. However some kinds of image processing can be very slow to run as PHP scripts.

This class provides a solution to create variants of a PNG image with a different background color, just by reading the PNG file contents and replacing a few bytes in the image file data directly.
