Function Documentation

sp_generate_internal_bitmap()

Inkscape::Pixbuf * sp_generate_internal_bitmap	(	SPDocument *	document,
		Geom::Rect const &	area,
		double	dpi,
		std::vector< SPItem const * >	items,
		bool	opaque,
		uint32_t const *	checkerboard_color,
		double	device_scale,
		std::optional< Antialiasing >	antialias
	)

Generates a bitmap from given items.

The bitmap is stored in RAM and not written to file.

Parameters

document	Inkscape document.
area	Export area in document units.
dpi	Resolution.
items	Vector of pointers to SPItems to export. Export all items if empty.
opaque	Set items opacity to 1 (used by Cairo renderer for filtered objects rendered as bitmaps).

Returns

The created GdkPixbuf structure or nullptr if rendering failed.
