Detailed Description

Filter to change pixel type of an image.

The following transformations are supported: Grayscale to RGB, ComplexRI, ComplexMP RGB to/from CMY, CMYK, IHS, BHS, HSV CMY to/from CMYK ComplexRI to/from ComplexMP If source image contains an alpha band it will be passed through unchanged if the target pixel type includes alpha. Output sample types are determined from output pixel type and sample range required. Sample types with predefined ranges exceeding 8-bit unsigned (eg Hue) will have a sample datatype sufficiently large to hold the possible range of sample values.

Constructor & Destructor Documentation

SPATMOD::IMAGE::FILTER_PIXELTYPE::FILTER_PIXELTYPE	(	STAGE *	pSourceImage,
		bool	TakeOwnership,
		PIXEL::TYPE	TargetPixelType,
		double	ColorMaxValue,
		DATATYPE	TargetDatatype = DATATYPE_Invalid
	)

Construct with specified target pixel type.

Parameters:

	pSourceImage	Source image stage
	TakeOwnership	Filter takes ownership of source stage and will delete when needed
	TargetPixelType	Target pixel type
	ColorMaxValue	Maximum value for color level (R, G, B, C, M, Y, K)
	TargetDatatype	Target data type, default derive from source and ColorMaxValue

Member Function Documentation

static bool SPATMOD::IMAGE::FILTER_PIXELTYPE::IsConversionValid	(	PIXEL::TYPE	SourcePixelType,
		PIXEL::TYPE	TargetPixelType
	)			[static]

Determine if this filter will support the conversion between types.

Can be used to set UI components without initializing the filter.

Parameters:

	SourcePixelType	Source pixel type
	TargetPixelType	Target pixel type
