Obtained result is [253 130 0], instead of expected [0, 130, 253]. It seems that color format is twisted (RGB -> BGR) during loading of PNG. The reason for that is a fact that big endian was not detected right in FreeImage.h. Patch that improves big endian detection in freeimage is attached. Using freeimage, that conatins these changes I was able to build skimage successfully on mips, with all tests passing. Could you please consider including this patch? The same test is failing on sparc and s390s (BE archs), I suppose that this fix could solve this issue on those architectures as well. Best Regards, Dejan
