I just wrote this bit (coming from Pascal) and am wondering how seasoned Python
programmers would have done the same? Anything terribly non-python?
As always, thanks for all input.

Last week some readers have kindly supplied ideas and code for a question I had
asked around a form of image data compression required for specialized display
hardware.
I was able to solve my issues for all but one:
The black & white only device (1024 (X) x 1280 (Y)) expects the compressed dat

I create an image as per:
img = Image.new('1', (1024, 1280), 1)
I then draw on it and do:
imagedata = list(img.getdata())
print len(imagedata)
This gives me 1228800 instead of the expected 1310720 (1024 * 1280)
- any ideas what I am missing?
As always, any help much

Judging from the message archive, the image-sig list is (just about) dead?
Disclaimer: Am a newbie - so anything is possible
using 'RGB' works fine
img = Image.new('RGB', (inktile[0], inktile[1]), bgcolor)
using '1' or 'L' does not (see trace below)
img = Image.new('L', (inktile[0]

Given
data = '{[][]}'
How can I efficiently get dictionaries for each of the data blocks framed by <>
?
Thanks for any help
