BINS clj

median-cut clj

(median-cut l)

Takes a list and sorts it by the elements with the greatest range and splits it at the median.

quantize clj

(quantize img n-colors)

Quantize an image to n colors. The underlying filter builds an octree to determine a set of colors that will produce minimal distortion, but these will be different colors for each image.

quantize-px-range clj

(quantize-px-range px range)

Quantize 32-bit ARGB(8888) pixels to RGB(222) format. On a little-endian machine this means we use the right most 6 bits

quantize-range-pixels clj

(quantize-range-pixels pixels quant-range)

quantized-palette clj

(quantized-palette img)

(quantized-palette img n)

Takes an image and returns a pallette of colors that could be used to quantize the image using the median-cut algorithm. Note that n must be a power of 2.

range-quantize clj

(range-quantize img range)

quantize the image so that each channel only has range integer precision. So if range is 4, you are only using 2 bits per channel. If range is 8, you are using 3 bits per channel

rough-quantize-color clj

(rough-quantize-color c range)
