Detailed Description

Abstract interface to plugable image support for the DICOMDIR class.

This is an abstract base class used as an interface to access DICOM images from the DicomDirInterface. The implementation can be found in dcmjpeg/libsrc/ddpiimpl.cc (incl. JPEG support).

Member Function Documentation

virtual OFBool DicomDirImagePlugin::scaleData	(	const Uint8 *	srcData,
		const unsigned int	srcWidth,
		const unsigned int	srcHeight,
		Uint8 *	dstData,
		const unsigned int	dstWidth,
		const unsigned int	dstHeight
	)		const [pure virtual]

scale image (pixel data) to specified size

Parameters:

srcData	pointer to 8 bit source pixel data (original image)
srcWidth	width of the source image
srcHeight	height of the source image
dstData	pointer to 8 bit destination pixel data (scaled image). This array needs to be allocated prior to calling this function.
dstWidth	width of the destination image
dstHeight	height of the destination image

Returns:

OFTrue if successful, OFFalse otherwise

Implemented in DicomDirImageImplementation.

virtual OFBool DicomDirImagePlugin::scaleImage	(	DcmItem *	dataset,
		Uint8 *	pixel,
		const unsigned long	count,
		const unsigned long	frame,
		const unsigned int	width,
		const unsigned int	height,
		const OFBool	decompressAll = OFFalse
	)		const [pure virtual]

scale image (from DICOM dataset) to specified size

Parameters:

dataset	DICOM dataset where the pixel data is stored (original image)
pixel	pointer to 8 bit destination pixel data (scaled image). This array needs to be allocated prior to calling this function.
count	number of bytes allocated for the 'pixel' array
frame	index of the frame to be scaled (0..n-1)
width	width of the destination image
height	height of the destination image
decompressAll	always decompress complete pixel data if true

Returns:

OFTrue if successful, OFFalse otherwise

Implemented in DicomDirImageImplementation.
