1synopsis: "Library implementing parsing of image formats such as PNG, BMP, PPM"
2description:
3"""
4The imagelib library implements image formats such as PNG, BMP, and PPM in
5OCaml, relying on only one external dependency: 'decompress'.
6
7Unix-dependent functionality such as reading or writing to files in the
8filesystem are packaged in the `imagelib.unix` findlib module inside this
9OPAM package; to use it you need to include `imagelib.unix` specifically
10in your project's dependencies, for instance `(libraries imagelib.unix)`
11in your Dune file.
12
13Supported image formats:
14 - PNG (full implementation of RFC 2083),
15 - PPM, PGM, PBM, ... (fully supported),
16 - BMP (read-only)
17 - JPG (only image size natively),
18 - GIF (only image size natively),
19 - There is an experimental native implementation available in the pure `ImageLib` module.
20 - XCF (only image size natively),
21 - Utility functions for handling unimplemented formats are available in
22 the 'imagelib.unix' findlib package and handle conversion from unsupported
23 image formats like JPG, GIF, XCF by converting them to PNG using the
24 `convert` commandline utility from `imagemagick`.
25
26As imagelib only requires `decompress`, it is suitable (excluding operations
27requiring the `imagemagick` `convert` binary) for compilation to javascript
28using `js_of_ocaml`, or inclusion in MirageOS unikernels.
29
30`app/imagetool.ml` contains an example binary that acts as a command-line interface to many of the functions in the library. It will be installed as `imagetool` or `imagetool.exe` if you use **opam** to install the library, and otherwise it will be in `_build/default/app/imagetool.exe`
