rnnlib process image

My confusion was, why Alex Graves do such processing to image, as his codes in arabic_offline.py:

image = Image.open(filename).transpose(Image.FLIP_TOP_BOTTOM).transpose(Image.ROTATE_270)

That’s because PIL Image object store data row-by-row, and Alex wants to read the data from column-wise from left to right.
So, after flip and rotate the reading order is the same as:
rnnlib process image_第1张图片
