static OFString DcmSegUtils::debugByte2Bin ( Uint8 b )

static

Dumps a byte as binary number to a string.

Only useful for debugging purposes.

Parameters

b	The byte to dump

Returns: A string containing b as a binary number

static void DcmSegUtils::debugDumpBin	(	Uint8 *	buffer,
		size_t	length,
		const char *	what
	)

static

Dumps a memory block byte for byte to the debug log stream.

Only useful for debugging purposes.

Parameters

buffer	The address of the memory block to dump
length	The length of memory to be dumped
what	String describing what is dumped.

static size_t DcmSegUtils::getBytesForBinaryFrame ( const size_t & numPixels )

static

Compute the number of bytes required for a binary pixel data frame, given the number of pixels.

Parameters

numPixels The total number of pixels

Returns: The number of bytes required to pack the data into a binary segmentation frame

static DcmIODTypes::Frame* DcmSegUtils::packBinaryFrame	(	Uint8 *	pixelData,
		const Uint16	rows,
		const Uint16	columns
	)

static

Pack the given segmentation pixel data, provided "unpacked", into the packed format expected by DICOM.

Parameters

pixelData	Pixel data in unpacked format
rows	Number of rows in the pixel data
columns	The number of columns in the pixel data

Returns: The frame data if successful, NULL if an error occurs

static void DcmSegUtils::shiftLeft	(	Uint8 *	buf,
		size_t	bufLen,
		Uint8	numBits
	)

static

Shifts the given memory block some defined number of bits to the left.

Bits that fall off the first byte are lost (i.e. no "cycled" shift).

Parameters

buf	The address of the memory buffer to shift
bufLen	The length of the buf memory block in bytes
numBits	The number of bits to shift. Must be 0 <= numBits <= 7.

static void DcmSegUtils::shiftRight	(	Uint8 *	buf,
		size_t	bufLen,
		Uint8	numBits
	)

static

Shifts the given memory block some defined number of bits to the right Bits that fall off the last byte are lost (i.e.

no "cycled" shift).

Parameters

buf	The address of the memory buffer to shift
bufLen	The length of the buf memory block in bytes
numBits	The number of bits to shift. Must be 0 <= numBits <= 7.

static DcmIODTypes::Frame* DcmSegUtils::unpackBinaryFrame	(	const DcmIODTypes::Frame *	frame,
		Uint16	rows,
		Uint16	cols
	)

static

Unpacks a binary segmentation frame into a "sparse" pixel data frame where every resulting byte represents a single bit of the frame being either 0 (not set) or 1 (set).

Parameters

frame	The input buffer with the frame in packed format
rows	The rows of the frame
cols	The cols of the frame

Returns: The segmentation frame in unpacked format. NULL in case of error.
