bimage — Image processing library

v0.3.1

bimage is an image processing library for OCaml.

Features

  • Simple image type based on bigarrays

  • Supports u8, u16, i32, i64, f32, f64 datatypes

  • Composable image operations

  • Image I/O using OpenImageIO (bimage-io)

  • Image I/O using ImageMagick/GraphicsMagick and stb_image (bimage-unix)

  • GLFW window support (bimage-display)

bimage is distributed under the ISC license.

Installation

bimage can be installed with opam:

$ opam install bimage

bimage-io can be installed by running:

$ opam install bimage-io

Additionally, bimage-unix, which provides stb-image and ImageMagick bindings, can be installed by running:

$ opam install bimage-unix

If you don't use opam consult the opam file for build instructions.

Getting started

  • Type.t: Defines the type of an image: u8, u16, f32, f64, i32ori64`

  • Color.t: Defines the color of an image: gray, rgb, rgba, xyz and yuv

    • It's possible to extend the color type by implementing COLOR

  • Image.t: Image type

  • Kernel.t: Convolution kernels

  • Transform.t: Image transformations

  • Expr.t: Expression combinator

    • Building blocks for image processing filters

  • Filter.t: Executable image filter

    • Makes Expr.t executable

There is a corresponding file for each of these types in src/.
