Member Function Documentation

void tb::TBFontFace::DrawString	(	int	x,
		int	y,
		const TBColor &	color,
		const char *	str,
		int	len = `TB_ALL_TO_TERMINATION`
	)

Draw string at position x, y (marks the upper left corner of the text).

int tb::TBFontFace::GetAscent ( ) const

inline

Get the vertical distance (positive) from the horizontal baseline to the highest character coordinate in a font face.

int tb::TBFontFace::GetDescent ( ) const

inline

Get the vertical distance (positive) from the horizontal baseline to the lowest character coordinate in the font face.

TBFontEffect* tb::TBFontFace::GetEffect ( )

inline

Get the effect object, so the effect can be changed.

Note: No glyphs are re-rendered. Only new glyphs are affected.

TBFontDescription tb::TBFontFace::GetFontDescription ( ) const

inline

Get the font description that was used to create this font.

int tb::TBFontFace::GetHeight ( ) const

inline

Get height of the font in pixels.

int tb::TBFontFace::GetStringWidth	(	const char *	str,
		int	len = `TB_ALL_TO_TERMINATION`
	)

Measure the width of the given string.

Should measure len characters or to the null termination (whatever comes first).

bool tb::TBFontFace::RenderGlyphs	(	const char *	glyph_str,
		int	glyph_str_len = `TB_ALL_TO_TERMINATION`
	)

Render all glyphs needed to display the string.

void tb::TBFontFace::SetBackgroundFont	(	TBFontFace *	font,
		const TBColor &	col,
		int	xofs,
		int	yofs
	)

Set a background font which will always be rendered behind this one when calling DrawString.

Very usefull to add a shadow effect to a font.
