I work with code that handles data in a particular way. Instead of using
the top-left corner as the origin, it uses the bottom left. It treats the
data as if it's sitting in quadrant 1 on an X-Y plane with the bottom left
corner sitting on the origin. The code expects me to read in the data
from the file starting with the 'first' row (the bottom row) to the top
row (the 'last' row) from left to right. If my image has n rows and m
columns, could I do something like this...?
RasterIO( GF_Read, 0, n, m, n, ...)
and would GDAL be smart enough to know that since I'm placing my origin at
the bottom left corner, it needs to read backwards or 'up' the image? If
it can't, that's ok - I'll just have to do some post processing on the
output buffer after the read. Changing the code around so it treats the
top left corner as the origin isn't an option. I don't have that kind of
authority and it'd be a massive change.
Thanks,
Todd
