Webb30 maj 2024 · PIL is the Python Imaging Library which provides the python interpreter with image editing capabilities. It was developed by Fredrik Lundh and several other contributors. Pillow is the friendly PIL fork and an easy to use library developed by Alex Clark and other contributors. We’ll be working with Pillow. Installation: WebbWe'll use the Pillow library that we used to load the image also to resize the image. img = Image.open('../../doc/_static/stinkbug.png') img.thumbnail( (64, 64)) # resizes image in-place imgplot = plt.imshow(img) Here we use the default interpolation ("nearest"), since we did not give imshow () any interpolation argument. Let's try some others.
WebbAll images are stored inside Shape nodes in a Document . To extract all images or images having specific type from the document, follow these steps: Use the Document.get_child_nodes method to select all Shape nodes. Iterate through resulting node collections. Check the Shape.has_image boolean property.
