Detailed Description

Header file for font rendering functions.

This file contains declarations for rendering text on a screen. It defines glyph data structures and functions for drawing both small and large text.

Function Documentation

drawBigText()

void drawBigText	(	Screen *	base,
		char *	str,
		u16	x,
		u16	y,

x	X-coordinate of the text position.
y	Y-coordinate of the text position.
drawMode	Drawing mode to be applied.

drawBigTextUnderline()

void drawBigTextUnderline	(	Screen *	base,
		u8	pos )

Draw a underline under a character when draw at the bottom of the screen.

Parameters

base	Pointer to the screen buffer.
pos	index of the char to underline

drawSmallText()

void drawSmallText	(	Screen *	base,
		char *	str,
		u16	x,
		u16	y,
		BitMapDrawMode	drawMode )

Renders small-sized text on the screen.

Variable Documentation

depixel

const BitMap depixel[]

extern

Predefined bitmap representations of glyphs.

This array contains bitmap structures for rendering font characters in a larger size.

glyphs

const u32 glyphs[128][4]

extern

Glyph data for ASCII characters 0-127.

This array stores 4x32-bit values per character, representing bitmap data for rendering small font glyphs.
