PIL(low) and multi-page TIFFS

问题 This should be relatively easy, but who knows... Is there a way to retrieve the number of frames in a multi-page TIFF file using PIL/Pillow, without iterating through the whole stack until seek raises an error? 回答1: Try using n_frames : from PIL import Image tiffstack = Image.open('my_img.tiff') tiffstack.load() print(tiffstack.n_frames) 来源： https://stackoverflow.com/questions/26660415/pillow-and-multi-page-tiffs
