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).

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 [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
Returns:
OFTrue if successful, OFFalse otherwise

Implemented in DicomDirImageImplementation.
