NAME
librifunktionsteckensnittsglyfrasteriseringsprogrambiblioteket - Font rasterisation library
DESCRIPTION
librifunktionsteckensnittsglyfrasteriseringsprogrambiblioteket is a C library
for converting shape outlines to filled shapes, with a focus on fonts, which
that it only supports filled, closed shapes and that the direction of the
outline determines whether a shape adds or subtracts to the image (the absolute
values of the result is used in the image). Furthermore this means that the
library only supports curve types that are used for drawing glyphs; specifically
this means that lines and quadratic Bézier curves are supported by cause this
is what is requied to draw vectorised bitmap fonts and TrueType fonts, but also
cubic Bézier curves as this is required for OpenType fonts and elliptical arcs
(elliptical rather than circular because it may be need required to strech the
circle to support outputs with different vertical and horizontal dot density and
to support subpixel antialiasing) as this is commonly used for corners when
stroking the outline of a glyph.
NOTES
Rifunktionsteckensnittsglyfrasteriseringsprogrambiblioteket (hyphenation:
ri|funk¦tions-tec¦ken|snit¦ts-glyf-ras¦ter¦iser¦ings-prog¦ram|bib¦lio¦te¦ket)
is Swedish for "the library for rasterising glyphs from spline fonts".
Because of the length of the library name, and length limitation on function
names, the functions in this library are namespaced with the prefix "rtgrpblib_".
