A built-in parameter for saving JPEGs and PNGs is optimize. from PIL import Image foo = Image.open(‘path/to/image.jpg’) # My image is a 200×374 jpeg that is 102kb large foo.size # (200, 374) # downsize the image with an ANTIALIAS filter (gives the highest quality) foo = foo.resize((160,300),Image.ANTIALIAS) foo.save(‘path/to/save/image_scaled.jpg’, quality=95) # The saved downsized image size … Read more
You can use the BytesIO class to get a wrapper around strings that behaves like a file. The BytesIO object provides the same interface as a file, but saves the contents just in memory: import io with io.BytesIO() as output: image.save(output, format=”GIF”) contents = output.getvalue() You have to explicitly specify the output format with the … Read more
Yes, this way: im = Image.open(‘image.gif’) rgb_im = im.convert(‘RGB’) r, g, b = rgb_im.getpixel((1, 1)) print(r, g, b) (65, 100, 137) The reason you were getting a single value before with pix[1, 1] is because GIF pixels refer to one of the 256 values in the GIF color palette.

I think ImageFont module available in PIL should be helpful in solving text font size problem. Just check what font type and size is appropriate for you and use following function to change font values. # font = ImageFont.truetype(<font-file>, <font-size>) # font-file should be present in provided path. font = ImageFont.truetype(“sans-serif.ttf”, 16) So your code … Read more
First, I downloaded a test TIFF image from this page called a_image.tif. Then I opened with PIL like this: >>> from PIL import Image >>> im = Image.open(‘a_image.tif’) >>> im.show() This showed the rainbow image. To convert to a numpy array, it’s as simple as: >>> import numpy >>> imarray = numpy.array(im) We can see … Read more
Following worked for me: ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/System/Library/Frameworks/Tk.framework/Versions/8.5/Headers/X11 /usr/local/include/X11 sudo pip install pil UPDATE: But there is more correct solution below, provided by Will. open your terminal and execute: xcode-select –install
Here’s a version that’s much simpler – not sure how performant it is. Heavily based on some django snippet I found while building RGBA -> JPG + BG support for sorl thumbnails. from PIL import Image png = Image.open(object.logo.path) png.load() # required for png.split() background = Image.new(“RGB”, png.size, (255, 255, 255)) background.paste(png, mask=png.split()[3]) # 3 … Read more
The error regarding the file extension has been handled, you either use BMP (without the dot) or pass the output name with the extension already. Now to handle the error you need to properly modify your data in the frequency domain to be saved as an integer image, PIL is telling you that it doesn’t … Read more
use this: pil_image = PIL.Image.open(‘Image.jpg’).convert(‘RGB’) open_cv_image = numpy.array(pil_image) # Convert RGB to BGR open_cv_image = open_cv_image[:, :, ::-1].copy()
The “friendly PIL fork” Pillow works on Python 2 and 3. Check out the Github project for support matrix and so on.
