Function Documentation

int DoThinRaster	(	INT32	numcols,
		INT32	numlins,
		int(*)(INT32, UINT8 *, void *)	,
		int(*)(INT32, UINT8 *, void *)	,
		void *	Clientdata,
		int	polyflag
	)

Perform line thinning on binary raster data.

Parameters:

numcols	Number of columns in raster
numlins	Number of lines in raster
Clientdata	Function to write line to raster To be passed to ReadFunc and WriteFunc
polyflag	Something to do with polygons?

int MfComputeRasterByQuery	(	const RVC::OBJITEM &	SrcItem,
		const MISTRING &	QueryString,
		RVC::OBJITEM &	DestItem
	)

Compute raster cell values by query.

Parameters:

SrcItem	Source raster
QueryString	Query string
DestItem	Destination instance to pass to RVC::RASTER::Make()

int MfConvert24bittoComposite	(	const RVC::OBJITEM &	,
		const RVC::OBJITEM &	,
		int	,
		int
	)

These next two functions will eventually be a filter in the image pipeline as a neural net classifier. Does color reduction to minimal necessary.

int MfConvertRGBtoComposite	(	const RVC::OBJITEM &	,
		const RVC::OBJITEM &	,
		const RVC::OBJITEM &	,
		const RVC::OBJITEM &	,
		int	,
		int
	)
