virtual void Facade::IDigitalPublishingRasterizerFacade::GetBoundingBoxForItemsInSpreadCoords	(	UIDList const &	items,
		PMRect &	bounds
	)		const

pure virtual

Calculates the bounding box for a list of UIDs, in spread coordinates, using the same method used internally by RasterizePageitemToStream. This ensures that bounding boxes can be calculated consistently.

Parameters

items	The page items to rasterize
bounds	Out param to receive the calculated bounds, in spread coordinates

virtual ErrorCode Facade::IDigitalPublishingRasterizerFacade::RasterizePageitemsToStream	(	UIDList const &	items,
		uint32	width,
		uint32	height,
		PMRect const *	explicitBounds,
		id_digpub::ObjectPtr const &	settings,
		IPMStream *	out
	)

pure virtual

Rasterizes the given page items to a specified width and height, scaling contents to fit, then saves the results to the specified stream.

settings is an optional dictionary which may include the following values (case-sensitive):

Compression: string, one of 'png', 'jpeg', or 'auto'. Default is 'auto' Downsampling: string, one of 'bicubic' or 'antialiased'. Default is 'bicubic' JPEGQuality: string, one of 'max', 'high', 'med', 'low', 'min'. Default is 'high' RasterizationScale: real, the scale at which to rasterize. Default is 1. IncludeAlpha: bool, if true the raster will have an alpha channel. Default is true ClipItems: bool, if true page items are clipped to their parent's bounds. Default is true FilterToSpread: bool, if true page items outside the spread bounds are omitted. Default is true ImageResolution: uint, the resolution at which to rasterize. Must be between 18 and 600. Default is 72

explicitBounds can be used to override the default bounding box calculation that would normally be used (the plug-in normally uses GetBoundingBoxForItemsInSpreadCoords to make this determination). It is the caller's responsibility to ensure that the bounding box is correct; the plug-in will not attempt to validate it.

Parameters

items	The page items to rasterize
width	The width of the resulting raster
height	The height of the resulting raster
explicitBounds	Optional bounding box for page items, in spread coordinates
settings	Settings to use during the export
out	The stream to which the raster is written

Returns: an ErrorCode describing success or failure of the operation
