ImagePalette_v100

[hh]

>>> The stack needs LC 9. It also runs in LC 8 but
>>> up to 10 times slower.

The stack creates a color palette from any image.
You set the number of colors (2-256) of the palette.

Such palettes are often used to create "harmonic" designs
of drawings/posters or for creating web pages.

You can see the "quantized" image with that palette, see
https://en.wikipedia.org/wiki/Color_quantization

The quantized image is computed built-in or by using
LC's "export image with palette" with the computed palette.

The stack uses the excellent javaScript library rgbQuant
https://github.com/leeoniya/RgbQuant.js/
via a browser widget. The library is included in the stack.

Download "ImagePalette" from "Sample Stacks" or from

If you have a decent GPU then around 1-2 seconds are
needed for images of medium screen size (1920x1080).
