Detailed Description

Ipe Painter using Cairo and Freetype as a backend.

This painter draws to a Cairo surface.

Constructor & Destructor Documentation

CairoPainter()

CairoPainter::CairoPainter	(	const Cascade *	sheet,
		Fonts *	fonts,
		cairo_t *	cc,
		double	zoom,
		bool	pretty,
		bool	filterBest
	)

Construct a painter.

zoom one means 72 pixels per inch. Set pretty to true to avoid drawing text without Latex.
