Hello Guilers,
I'm pleased to announce Guile-PNG 0.4.0, Portable Network Graphics
(PNG)[1] library for GNU Guile, implemented in pure scheme:
https://github.com/artyom-poptsov/guile-png/releases/tag/v0.4.0
This release fixes a bug in implementation of <rectangle> class and
another bug in tests. Also Guile-PNG updated to work with Guile-SMC
0.6.
The library uses Guile-ZLIB[2] to compress/decompress the PNG data.
Also this is the third project of mine that uses Guile State Machine
Compiler (Guile-SMC)[3].
