Hi
I am looking for a way that I could extract each segment of a grid
into a separate file.
Say I have a scanned image of a piece of maths paper with numbers
and letters in it. Could GIMP either:
a. Extract each segment based on the colour of the grid on the
maths sheet (a speciic colour)
or
b. Once the grid has been deleted (select the maths paper grid
colour using the colour area picker in GIMP) create a new grid that
is the same size as the maths paper grid and export each segment of
that grid into different images.
Is this possible to do? I have Gimp 2.0 installed on a Windows xp
machine. I understand that it may require the use of command
lines... if so, I am willing to learn how to do use them to get
this done.

William
The nearest thing you will find are scripts to cut and save a image
along guides (teh ones you drag from the rulers on the sides of the
image).
The guillotine plug-in just chops a image along the lines, creating
various open images in teh GIMP - you then have to save them by hand.
However, both the PERL-FU and PYTHON-FU extensions have plug-ins that
will both cut along the lines _and_ save an image to disk as part of
an HTML table (the image files are separate.
The matter is, none of this is available for windows. (Python-fu is,
but hjust for the development version of the GIMP - 2.3.6 and newer)
