Detailed Description

Abstract interface to pluggable 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

scaleData()

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.

scaleImage()

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.
