Features

Quantization

• Quantize using K-Means algorithm.
• Quantize using Median-Cut algorithm.
• Quantize using Octree algorithm.
• Quantize using RGB collapse algorithm.

Misc.

• Search using a set of colors (from an open image) and a target images count.
• Crop.
• Upscale and downscale using linear and nearest filters
• Display colors' amounts per image
• Display RGB color graphs.

FLT format

An indexed images format that saves each color in the colormap's repeatition, the format's standard is provided in Encoder's code.
