1. doxygen generated API reference

The automatically generated class reference can be read at this location. It has been generated with the nice doxygen tool.

2. Object Model

3. Using Font Primitives

nrec uses a special bitmap file format (.bmf) for fonts. There is a command line tool called ttf2bmf that can be used to convert ttf font files into bmf files. The font size specified defines the file size and the resolution of the font bitmaps and defaults to 12.

Usage: 

./ttf2bmf fontfile outputfile [fontsize]

Examples: 

$ ./ttf2bmf LucidaTypewriterRegular.ttf default.bmf 24
./ttf2bmf: Wrote default.bmf, 256 by 256 pixels.
$ ./ttf2bmf LucidaTypewriterRegular.ttf default.bmf 10
./ttf2bmf: Wrote default.bmf, 256 by 64 pixels.
$ ./ttf2bmf LucidaTypewriterRegular.ttf default.bmf 48
./ttf2bmf: Wrote default.bmf, 256 by 1024 pixels.
$ ./ttf2bmf LucidaTypewriterRegular.ttf default.bmf
./ttf2bmf: Wrote default.bmf, 256 by 128 pixels.
