Data Fields
uint8_t	width
	Bitmap width in pixels.
uint8_t	height
	Bitmap heigth in pixels.
int8_t	bearing_x
	An X offset to be applied before we start drawing.
int8_t	bearing_y
	An Y offset from baseline to the top of the bitmap.
uint8_t	advance_x
	An offset to be applied after drawing.
uint8_t	bitmap []
	A character bitmap.

Detailed Description

A data describing single Glyph.

Note that glyph do not necessarily correspond to one character (for example ligature is a glyph but corresponds to at least two characters).

The glyphs are rendered to horizontal baseline, vertical rendering is not supported.

The structure could contain glyphs of different BPP and information about the bitmap format is stored in the font structure. The bitmap lines are byte aligned.

Field Documentation

advance_x

uint8_t gp_glyph::advance_x

An offset to be applied after drawing.

This defines a basepoint for next glyph.

Definition at line 51 of file gp_font.h.

bitmap

uint8_t gp_glyph::bitmap[]

A character bitmap.

This is width * height * depth bits rounded up to closest whole byte.
