Description

Gpmatrix2GimpPalette saves a matrix into a Gimp palette file (gpl) Gpmatrix2palette save a palette from matrix data with optional palette indeces and the option to modify the palette for solid colors GpcreateIndexFromMatrixAndPalette from a matrix with RGB colors (decimal 24bit) from an image file and its palette as a vector, create a matrix with indices GpcreatePaletteFromMatrix from a matrix with RGB colors (decimal 24bit) from an image file create a palette of 256 colors (decimal 24bit), as a vector GpgimpPalette2matrix reads a Gimp palette into a matrix, optionally the index can be returned too GppalettePlot plots a palette from an indexed PNG file GpshowPaletteColornames get gnuplot's RGB color names as a dataframe - 'ColorName','ColorHex','R','G','B'

Usage

Gpmatrix2GimpPalette(paletteMatrix, gplFileName, GimpColumns=16)
