Hi all, I'm using the below code to extract colors, but now, I need to extract colours with the alpha channel.
I've read the PIL Doc and googling a lot, and I didn't find any information of how to load a RGBA palette, so the extractcolours method can couple with image alpha sections. def load_palette(colour_map): mapim = Image.open(colour_map) palette = [color[:3] for _, color in mapim.getcolors()] # Flatten colors to be accepted by PIL palette = tuple(reduce(lambda a, b: a+b, palette)) # create palette self.impalette = Image.new("P", (1, 1)) self.impalette.putpalette(palette) def extractcolours(filename): pilimage = Image.open(filename) im_quantized = pilimage.convert("RGB").quantize(palette=self.impalette) im_in_rgba = im_quantized.convert("RGBA", dither=self.dither) return im_in_rgba.getcolors() What I've get with this code for images with transparency is the list of colours, and the one colour : (0,0,0,255) (and all the ohters colors with alpha = 255) The convert tool from Imagemagick, return me the list of colours with all the non-(0,0,0) colours with alpha channel = 255 and (0,0,0,0). So with this list, I can couple with the aplha sections removed from my results. It's possible to do this with PIL? Thanks a lot.
