Converting images
Convert image from one scheme to another
Using getinverse()
it's possible to convert an image from one colorscheme to another.
convert_to_scheme(cscheme, img)
returns a new image in which each pixel from the provided image is mapped to its closest matching color in the provided scheme.
using FileIO
# image created in the ColorSchemes documentation
img = load("ColorSchemeTools/docs/src/assets/figures/heatmap1.png")
Here, the original image is converted to use the GnBu_9
scheme.
img1 = save("/tmp/t.png", convert_to_scheme(ColorSchemes.GnBu_9, img))
ColorSchemeTools.convert_to_scheme
— Function.convert_to_scheme(cscheme, img)
Converts img from its current color values to use only the colors defined in cscheme.
image = nonTransparentImg
convert_to_scheme(ColorSchemes.leonardo, image)
convert_to_scheme(ColorSchemes.Paired_12, image)
