There's a histogram method allowing you to pull some statistics out of an image. The library also supports image resizing, rotation and arbitrary affine transforms. This can be used for automatic contrast enhancement, and for global statistical analysis. This library provides extensive file format support, an efficient internal representation, and fairly powerful image processing capabilities. Qt works very well with graphics. You can find versions in other formats, as well as earlier versions, in dead link.

To save a file, use the save method of the Image class. It should provide a solid foundation for a general image processing tool. Image Processing The library contains basic image processing functionality, including point operations, filtering with a set of built-in convolution kernels, and colour space conversions. If the image was not read from a file, it is set to None. This is done by reconfiguring the image decoder.

Enhancement For more advanced image enhancement, use the classes in the ImageEnhance module. This edition covers release 1. Also, the underlying data structures are from Numpy and Scipy, which makes its code incredibly interoperable. I got it to compile ok, but it didn't actually work. Colour Transforms The Python Imaging Library allows you to convert images between different pixel representations using the convert function.

As of March 30, 2012, I have tried and failed to get the sloonz fork on GitHub to open images. I tried doing sudo apt-get install python-imaging but now when i run python selftest. A more general form of image transformations can be carried out via the transform method.

Values in-between indicate different levels of transparency. To load an image from a file, use the open function in the Image module. In this mask, the value 255 indicates that the pasted image is opaque in that position that is, the pasted image should be used as is. The current version identifies and reads a large number of formats. The library also supports image resizing, rotation and arbitrary affine transforms.

Write support is intentionally restricted to the most commonly used interchange and presentation formats. To rewind the file, you may have to reopen it. In most cases, a function object expecting one argument can be passed to the this method. Once created from an image, an enhancement object can be used to quickly try out different settings. The library automatically determines the format based on the contents of the file.

This library provides extensive file format support, an efficient internal representation, and fairly powerful image processing capabilities. Using the Image Class The most important class in the Python Imaging Library is the Image class, defined in the module with the same name. Last updated January 8, 2018. In short is a convenient and becoming a standard way of installing python libraries. Once you have an instance of the Image class, you can use the methods defined by this class to process and manipulate the image. It should provide a solid foundation for a general image processing tool. For debugging, there's also a show method which saves an image to disk, and calls an external display utility.
