Flood fill with Graphicsmagick or pgmagick

Question

Question

What is a good way to use flood fill with the Graphicsmagick command line or its pgmagick wrapper for python?

Background

So far this is what I have, but its saying that the signatures do not match:

Code:

from pgmagick import Image, ColorRGB

img = Image('C:\\test.png')
cRGB = ColorRGB(256.0, 256.0, 256.0)
geo = Geometry(1,1)
img.floodFillColor(geo, cRGB, cRGB)

Error:

  File "C:/Dropbox/COC/automate/coc_automate/python/__init__.py", line 62, in take_main_screen_shot
    img.floodFillColor(geo, cRGB, cRGB)
Boost.Python.ArgumentError: Python argument types in
    Image.floodFillColor(Image, Geometry, ColorRGB, ColorRGB)
did not match C++ signature:
    floodFillColor(class Magick::Image {lvalue}, class Magick::Geometry, class Magick::Color, class Magick::Color)
    floodFillColor(class Magick::Image {lvalue}, class Magick::Geometry, class Magick::Color)

Extra

Also, if you know of a better way that I can manipulate graphics from a Python application or the windows command line, I'm all ears. I'm starting to feel like I may be using the wrong tool for this with the state of the documentation.

Answer 1

I would recommend taking a look at the Python Imaging Library (PIL)

e.g. draw a gray cross over an image

import Image, ImageDraw

im = Image.open("lena.pgm")

draw = ImageDraw.Draw(im)
draw.line((0, 0) + im.size, fill=128)
draw.line((0, im.size[1], im.size[0], 0), fill=128)
del draw 

# write to stdout
im.save(sys.stdout, "PNG")
