This is a library written in C to render text from fonts generated by BMFont. The name of the library (LibDSF) comes from "DS Font library".

In order to use this library, download the Bitmap Font Generator tool (or any other compatible tool), export the font image to PNG, and export the font data in binary format.

This library can load font data from RAM or from the filesystem. It won't load textures for you, you're in charge of converting the PNG files to a DS-compatible format and loading them to RAM (and VRAM).

Currently, only fonts with one single PNG file are supported.

It supports drawing text as a bunch of quads, or generating a texture with the text rendered by software so that it can be loaded as a texture and drawn as one quad.

The software rendering routines support all NDS texture formats except for Tex4x4 compressed textures.

Important: Your source code files (or text data files) need to be encoded as UTF-8.

Note: If the replacement character � (U+FFFD) codepoint is included in the font, it will be used to print missing characters in the font, or when the UTF-8 string has encoding errors.

You can install this library with wf-pacman directly:

wf-pacman -Sy blocksds-libdsf

If you want to build the library from source, simply run this to build and install the library in your BlocksDS environment:

make install

Once you have installed the library, go to the folder of the example and run:

make

This will generate a NDS file that you can test with flashcards or emulators.

This library is released under the Zlib license.
