bimage — Image processing library

v0.5.0

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, i32 or i64

  • 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/.

Build status

Results of building bimage-unix with each compiler on check.ci.ocaml.org, run of against opam-repository 8a77e58. All results for this package.

Each result links to its build log. To keep crawlers from overloading the site, build logs require a GitHub sign-in (see ocurrent/opam-health-check). On your first log, GitHub asks you to “Authorize opam-health-check”, the OCurrent app that runs these checks; it sees only your public profile, not your repositories. The sign-in lasts 30 days.
