Hello Guilers,
I'm pleased to announce Guile-PNG 0.2.0, Portable Network Graphics
(PNG)[1] library for GNU Guile, implemented in pure scheme:
https://github.com/artyom-poptsov/guile-png/releases/tag/v0.2.0
This version adds ability to draw graphical primitives over PNG images.
Please see the Texinfo documentation for the new API description.
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].
