How to detect color from PDF Python

Question

Is there any way, in Python, of automatically detect the colors in a certain area of a PDF and either translate them to RGB or compare them to the legend and then get the color?

Answer 1

Felipe's approach didn't work for me, but I came up with this:

#!/usr/bin/env python
# -*- Encoding: UTF-8 -*-

import minecart

colors = set()

with open("file.pdf", "rb") as file:
    document = minecart.Document(file)
    page = document.get_page(0)
    for shape in page.shapes:
        if shape.fill:
            colors.add(shape.fill.color.as_rgb())

for color in colors: print color

This will print a neat list of all unique RGB values in the first page of your document (you could extend it to all pages, of course).
