Description Author

This class can create an image with color of another image dominant color.

It can take a given image and resizes it to a small size using ImageMagick extension to apply a gaussian filter during resizing and then use the quantize filter to reduce the colors and find out the dominant color.

The class can generate a new image using the dominant color and returns it as a data URL string for a GIF image with one pixel of that color.

Some applications need to display an image in a background that matches the most common color of the image.

This package can find the dominant color of an image and creates a new image in the GIF format with one pixel using that dominant color.
