A simple library to render Haiku Vector Icons

⚠️ Do not use this library. It is not ready yet.

The Haiku operating system uses a custom format to represent vector icons. The Haiku Vector Icon Format (hvif) is optimized to create tiny files that can be saved with the file metadata. For a good technical overview of the format see this blog post by Leah Hanson. The goal of this library is to allow the usage of this format outside the Haiku context.

It is written in modern standard C. As a goal it should feature a parser and rasterizer without any dependencies beyond libc.

Furthermore, a toy tool to convert hvif files into png files is included.

The author is not associated with the Haiku project.

Current State

The library is currently under heavy development. The current parser should be able to parse hvif files created with current Haiku builds, but is mostly untested. There is no standalone rasterizer yet, but an experimental rasterizer based on cairo is included. The purpose of this rasterizer is testing. It is not feature complete, but renders most real world icons reasonably well.

The next step is the preparation of a testing infrastructure. This should be done before work on the rasterizer begins.

Compiling

The build system is standard auto tools. To compile on a fresh clone run:

$ autoreconf -i
$ ./configure
$ make -j

HTML documentation can be generated with make html if Doxygen is installed.
