Detailed Description

Class XMLGlyphPrinter is an abstract glyph printing interface.

A glyph is an atomic part of printed data, e.g. a letter or an UTF character. More complex glyphs are extensible glyphs. Glyphs are also atomic (leafs) within the resulting block structure of the layout.

An XMLGlyphPrinter implementation provides a library independent way to draw glyphs on some initialized device. You pass the printer to the layouter to draw your output.

Member Function Documentation

virtual void crp::XMLGlyphPrinter::get_size	(	const std::string &	character,
		double &	width,
		double &	height
	)		[inline, virtual]

Returns the size of the given unicode character.

Parameters:

character	Unicode character
width	This value is overwritten with the width
height	This value is overwritten with the height

virtual void crp::XMLGlyphPrinter::print_character	(	int	x,
		int	y,
		const std::string &	character
	)		[inline, virtual]

Prints a single unicode character at the given position.

A glyph is printed by calling this method several times a the glyphs positions. The glyph is printed into the rectangle, which starts at (x,y) and extends into the ascending coordinate directions. The width and height of the rectangle for a character can be queried by calling the get_size method.

Parameters:

x	X-Coordinate of the drawing point
y	Y-Coordinate of the drawing point
character	Unicode character to print
