Pillow composite

Pillow composite Image module of the image processing library Pillow PIL of Python provides composite for compositing two images according to a mask image. Note that composite is a function to composite two images of the same size. Use the paste to composite images of different sizes, pillow composite.

If you have two images A and B, you alpha-composite A over B, it will create an effect that you can see both image A and B in the resulting image, as if A has transparency and you can see through A and also see B. Suppose a is the src image, b is the destination image, we composite a over b. The equation for alpha value and pixel value of the generated image are:. So it is easy to see that the resulting pixel value is a linear combination of pixel value from a and b. To test the correctness of the above equations, use the above script.

The Image module of the image processing library Pillow PIL of Python provides composite for compositing two images according to a mask image. Note that composite is a function to composite two images of the same size. Use the paste to composite images of different sizes. There are three parameters for composite. All three must be Image objects, all of the same size.

Since PIL is no longer under development, Pillow is now widely used. Although advanced image processing face recognition, optical flow, etc. Because Pillow is simpler and easier to understand than OpenCV, it is better to use it depending on the purpose. See the following link for individual articles that explain various processes such as resizing and trimming. Pillow and PIL cannot coexist. If you have installed both, you should uninstall both and reinstall only one. Note that if you are using Python 3, you may have to use pip3 instead of pip depending on your environment. Read the image file. Note that the name of the package to import is PIL , not Pillow.

Otherwise, you will get a opaque look for those regions. Importing Image module from PIL package. Draw mask draw. The transparency decreases as we increase the value of alpha. This will not affect the region in A that do not have overlap with image B. This article is being improved by another user right now. The larger alpha gets, the less you will see the underlying part of image A. If you want to show partial A and B, you can set alpha to a value between 0 and For RGB images, this is done for per-channel per-pixel. So if we have a large image A and we want to overlay a small image B onto it. Improved By :.
