Thanks, Michael. That looks like a smart way of doing it!
It works but the crop parameters are actually (x0, y0, x1, y1) so the code should read:
small(x,y) = I.get_crop(B*x,B*y,B*(x+1)-1,B*(y+1)-1).mean();.

I am trying to pixelate an image such that each region of the image corresponds to the average of a certain number of surrounding pixels. For example, I would like to take a 256x256 grayscale image and produce another 256x256 grayscale image that only contains 16x16 blocks. Sometimes this is also called image binning.
I figured that one way of doing this would be to downsample the 256x256...

Okay I got this to compile for Windows CE in a bit of a hackish way. Just please let me know if you think this will break anything. Windows CE does not support system(), getenv(), or remove(). I started by changing cimg_OS to 0, then:
_____________________________________________
LINE 4539:
Removed
return cimg_std::system(command);

And here is the list of errors when setting cimg_OS = 2 and cimg_display = 0:

It looks like some of my problems stem from the same place at this forum:
https://sourceforge.net/forum/forum.php?thread_id=3312623&forum_id=334630
That should get me started I think.

I made a little progress. I discovered that the file winnetwk.h is included in the OS if the following option is included in the catalog from platform builder: "Windows Networking API/Redirector (SMB/CIFS)"
After adding that and recompiling the OS, I no longer get the include error. Here is a list of errors I get when compiling with cimg_OS = 2 (Windows):
CImg.h(4526) : error...

The first major roadblock is at line 138 of CImg.h version 1.3.1.
It tries to include "shlobj.h" but this header itself throws an error because it can't find winnetwk.h of its own includes. This only happens when trying to compile for the embedded device and no problem for a standard Win32 application. Do you know exactly what shlobj and winnetwk are doing and why that would be a...

I would love to compile CImg into an embedded platform application but I get dozens of errors when compiling the main header file. I have tried setting the defines to both Windows and Unknown operating systems, but both have major problems. Has anyone successfully compiled CImg for Windows CE or any other embedded OS for an ARM processor? (I am using TI's OMAP processor) I thought I would ask...
