imageproc

crates.io doc-badge License Dependency status

An image processing library, based on the image library.

API documentation

Goals

A performant, well-tested, well-documented library with a consistent API, suitable for use as the basis of computer vision applications or graphics editors.

Non-goals

Maximum genericity over image storages or formats, or support for higher-dimensional images.

Color Space

Functions in this library implicitly assume that pixels colors are stored in a linear color space like RGB as opposed to a non-linear color space such as sRGB.

If you are not familiar with gamma correction then this article contains an introduction and examples of color artefacts resulting from not using linear color spaces.

Parallelism

This library provides both single-threaded and multi-threaded variations of several functions by using rayon.

Depending on image size and the amount of work performed per pixel the parallel versions may not always be faster - we recommend benchmarking for your specific use-case.

Crate Features

Default Features

  • rayon: enables multi-threaded versions of several functions

Optional Features

  • katexit: enables latex in documentation via katexit
  • property-testing: enables quickcheck
  • quickcheck: exposes helper types and methods to enable property testing via quickcheck
  • display-window: enables sdl2
  • sdl2: enables the displaying of images (using imageproc::window) with sdl2
