synopsis: "Library implementing parsing of image formats such as PNG, BMP, PPM"

description:

"""
4
+
The imagelib library implements image formats such as PNG, BMP, and PPM in
5
+
OCaml, relying on only one external dependency: 'decompress'.
6
+
7
+
Unix-dependent functionality such as reading or writing to files in the
8
+
filesystem are packaged in the `imagelib.unix` findlib module inside this
9
+
OPAM package; to use it you need to include `imagelib.unix` specifically
10
+
in your project's dependencies, for instance `(libraries imagelib.unix)`
11
+
in your Dune file.
12
+
13
+
Supported 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
+
26
+
As imagelib only requires `decompress`, it is suitable (excluding operations
27
+
requiring the `imagemagick` `convert` binary) for compilation to javascript
28
+
using `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`
