Pixel Manipulations

[PyPK]

Does anyone know of a simple implementation for detecting straight line
..So something like if we have a 2D arary of pixel elements representing
a particular Image. How can we identify lines in this Image.
for example:

ary =
[[1,1,1,1,1],
[1,1,0,0,0],
[1,0,1,0,0],
[1,0,0,1,0],
[1,0,0,0,1]]
So if 'ary' represents pxl of an image which has a horizontal line(row
0),a vertical line(col 0) and a diagonal line(diagonal of ary). then
basically I want identify any horizontal or vertical or diagonal line
anywhere in the pxl array and return true if its composed of only lines
else false...

Thanks.

Please do no post the same message twice, especially not with two different
