Member Function Documentation

◆ Create()

void FontPlan::Create	(	unsigned	width,
		unsigned	height,
		char32_t	firstch,
		char32_t	numch
	)

Initializes a background process (thread) for preparing information to be used by LoadGlyph.

Parameters

width	Width of font in pixels
height	Height of font in pixels
firstch	First unicode codepoint to initialize
numch	Number of unicode codepoints to initialize

Attempts to find the best representation for each glyph in this range, using information in share/fonts/preferences.txt . If a font by the exact requested size is not found, attempts to find closest match.

If the parameters are identical to when the function was last called, does nothing.

◆ LoadGlyph()

FontPlan::Glyph FontPlan::LoadGlyph	(	char32_t	ch,
		unsigned	scanline,
		unsigned	render_width
	)		const

Loads glyph for the given codepoint. Waits until the background process started by Create() has finished, if necessary.
