|
|
# duplicate scanning. The transforms seems to work fine (if I try to save the image after
|
|
# the transform, we see that the image has been correctly flipped and rotated), but the
|
|
# analysis part yields wrong blocks. I spent enought time with this feature, so I'll leave
|
|
# like that for now. (by the way, orientations 5 and 7 work fine under Cocoa)
