Below is some code to get you started.
To simplify testing I wrote a small program that uses PIL to generate colored squares and saves them to a folder. I tested these programs using Python 2.6.6 on Linux. They should work on Python 3, (assuming Tkinter & PIL are installed properly on your system) but you will need to change import Tkinter as tk to
import tkinter as tk in tk_frame_grid.py.
This program generates 30 colored squares, saving them to the 'squares' folder in the current directory. You need to create 'squares' before running the program.
PIL_2colorsquares.py
#! /usr/bin/env python
''' Create squares that fade from one color to another & save
Written by PM 2Ring 2015.07.18
'''
from PIL import Image
from itertools import permutations
def color_squares(size, colorpairs, basename, ftype):
#Make the composition mask
m = 255.0 / (2 * size - 2)
r = range(size)
mask = Image.new('L', (size, size))
mask.putdata([int(m * (x + y)) for y in r for x in r])
for count, (c0, c1) in enumerate(colorpairs):
im0 = Image.new('RGB', (size, size), color=c0)
im1 = Image.new('RGB', (size, size), color=c1)
im = Image.composite(im0, im1, mask)
im.save('%s%03d%s' % (basename, count, ftype))
def main():
size = 64
colors = ('red', 'yellow', 'green', 'cyan', 'blue', 'magenta')
colorpairs = permutations(colors, 2)
basename = 'squares/sq'
ftype = '.png'
color_squares(size, colorpairs, basename, ftype)
if __name__ == '__main__':
main()
This program first fills a list with PIL images, using image files from a named directory; these images can be in any file format that PIL can read. It then creates a Tkinter window containing a Frame that holds a grid of Buttons using the images. There is no error checking, so don't put non-image files into the 'squares' folder.
You need to specify the grid dimensions. If there aren't enough images to fill the grid you will get a StopIteration error.
