kzsError kzuBitmapFontCreate	(	struct KzuBitmapFontSystem *	bitmapSystem,
		kanzi::Domain *	domain,
		struct KzuBitmapFont **	out_bitmapFont
	)

		kanzi::Domain *	domain,
		kzString	fntFileContent,
		struct KzuBitmapFont **	out_bitmapFont
	)

		kzUnicodeChar	character
	)

Returns the glyph index in the font for the given unicode code point.

void kzuBitmapFontGetCharacterMetrics	(	const struct KzuBitmapFont *	bitmapFont,
		kzUint	glyphIndex,
		kzFloat *	out_advance,
		struct KzcRectangle *	out_boundingBox
	)

Returns the advance of given character using bitmap font.

kzFloat kzuBitmapFontGetKerning	(	const struct KzuBitmapFont *	bitmapFont,
		kzUint	previousGlyphIndex,
		kzUint	glyphIndex

		kanzi::Renderer *	renderer,
		kzUint	glyphIndex,
		kzFloat	x,
		kzFloat	y
	)

Draws a character at given coordinates.

The coordinates indicate the character left point on the baseline. This function is meant for debugging purposes only. For real text rendering, use KzcTextLayouter.

kzsError kzuBitmapFontPrepareTextLayout	(	struct KzuTextLayout *	textLayout,
		kanzi::Renderer *	renderer
	)

Prepares the given pre-layouted text for fast rendering using bitmap font.

kzsError kzuBitmapFontDrawTextLayout	(	struct KzuTextLayout *	textLayout,
		kanzi::Renderer *	renderer,
		kzFloat	x,
		kzFloat	y
	)

Draw the given pre-layouted text using bitmap font.

kzsError kzuBitmapFontDrawTextLayout3D	(	struct KzuTextLayout *	textLayout,
		kanzi::Renderer *	renderer
	)

Draw the given pre-layouted text in 3D space using bitmap font.

kzsError kzuBitmapFontFreeTextLayoutData ( struct KzuTextLayout * textLayout )

Frees the data and resources created by the prepare function.
