APNG extension to PNG plugin¶
Animated Portable Network Graphics (APNG) images are not fully supported but can be opened via the PNG plugin to get some basic info:
im = Image.open("image.apng") print(im.mode) # "RGBA" print(im.size) # (245, 245) im.show() # Shows a single frame
Check for libjpeg-turbo¶
You can check if Pillow has been built against the libjpeg-turbo version of the libjpeg library:
from PIL import features features.check_feature("libjpeg_turbo") # True or False
Negative indexes in pixel access¶
When accessing individual image pixels, negative indexes are now also accepted. For example, to get or set the farthest pixel in the lower right of an image:
px = im.load() print(px[-1, -1]) px[-1, -1] = (0, 0, 0)
Now uses one resize operation with
box parameter internally
instead of a crop and scale operations sequence.
This improves the performance and accuracy of cropping since
box parameter accepts float values.
