i trying convert array image ( tif ) compression (it undone @ other end). however, i'm falling @ first hurdle... i have following: pillow_image = image.fromarray(image_data) which gives me error: file "/users/workspace/test-app/env/lib/python2.7/site-packages/pil/image.py", line 2155, in fromarray arr = obj. array_interface attributeerror: 'tuple' object has no attribute ' array_interface ' what i'm doing wrong here? image_data tuple of 4 numpy arrays, each (probably) of shape (h, w). need image_data single array of shape (h, w, 4). therefore, use np.dstack combine channels. at least 1 of arrays has dtype int32. use 8-bit color channel, arrays needs of dtype uint8 (so maximum value 255). can convert array dtype uint8 using astype . data not contain values greater 255. if does, astype('uint8') keep least significant bits (i.e. return number modulo 256). image_data = np.dstack(image_dat...
