Hello,
switching to 64-bit Python and OS might help. I can display 8bit images
up to 8459x8459 with imshow on Windows 7 64-bit with 8GB RAM. Python
then uses about 5.5 GB RAM according to task manager. A 8460x8460 or
larger 8bit images crash Python (definitely a bug). The 32-bit
interpreter st

Hi Perry,
to clarify what I am doing - maybe the error lies in here:
* First I am building up a list of the corrected+rotated images
* After that is done I am creating the figure
* Then looping over every image, creating proper axes for each
individual image and finally:

Dear all,
I am trying to write a script to be used with our microscope, stitching
images of various magnifications together to yield a big picture of a
sample. The preprocessing involves operations like rotating the picture
etc., and finally those pictures are being plotted using imshow.
