Image Grabber

The script grabs a very small portion of screen (8px X 8px) around the current position of the mouse, through the OpenGL buffer, and save it.

import Blender

from Blender.BGL import *
import Image

coords = Blender.Window.GetMouseCoords()

imX = 8
imY = 8

depth = 3 # 3 channels RGB

buf = Buffer(GL_BYTE, imX * imY * depth)

glReadPixels(coords[0], coords[1], imX, imY, GL_RGB, GL_BYTE, buf)

image = Image.new('RGB', (imX, imY))

for i in range(imX):
	for j in range(imY):
		pos = (i * imY + j) * depth
		image.putpixel((i, j), ( buf.list[pos], buf.list[pos + 1], buf.list[pos + 2]))

image = image.transpose(2) #rotate 90 degre
image.save('test.png')

print 'Image saved'
