void cass::hllDataTypes::CASS2HLL	(	const inputContainerType &	CASSMatrix,
		outputContainerType &	HLLMatrix,
		size_t	quadrantColumns,
		size_t	quadrantRows,
		size_t	CASSColumns
	)

convert a linearised matrix in the CASS format to the hll format

the difference between the CASS and HLL is, that the CASS format has all 4 quadrants in a quadrat wheras in HLL they are aligned in a rectangle.

The numbers indicate the tile of the frame wihtin the HLL frame format, the letters indicate the tiles within the CASS format. The arrows indicate the fast increasing coordinate within the linearised array. The parenthesis and the 0 indicate where the hole btw the quater holes are in the new tiles. This implies that the top two tiles in the CASS format have to be rotated by 180 degrees before adding them to HLL format array. This basically mean that one has to read these tiles reverseley. This is done in this function by using reverse iterators that will point at the last element of the tile.

This function will then read the first row of tile A then the last of tile C then the last row of tile C, then the first row Tile B to the first row of the HLL format. The second row of the HLL format is then build by the 2nd row of Tile A, the 2nd to last row of Tile C then the 2nd to last row of tile D and the 2nd row of tile B. This continues until one has read all the rows of the tiles.

Template Parameters

inputContainerType	the type of the container containing the input
outputContainerType	the type of the container containing the output

Parameters

CASSMatrix	the container containing the linearised input matrix
HLLMatrix	the container containing the linearised out matrix
quadrantColumns	the number of columns in one quadrant
quadrantRows	the number of rows in one quadrant
CASSColumns	the number of columns in the CASS input container

This is done in this function by using reverse iterators that will point at the last element of the tile.

This function will then read the first row of tile 0 then the first rowv of tile 3. Then the 2nd row of tile 0 and then the 2nd row of tile 3. This continues until all rows of the tiles have been read. It then continues with the last of tile 1 and the last row of tile 2. Then the 2nd to last row of tile 1 and the 2nd to last row of tile 2. This continues until all rows of the tiles have been read.

Note

The resulting image in the CASS format is rotated by 90 degrees clockwise to the image as it would look like inside the lab frame if one looks into the beam.
