Detailed Description

IImageShiftUtils is a utility class used to shift a row of image data a specified number of bits to the left or right. i.e. Utils<IImageShiftUtils>()->ShiftImageRowLeft( ... ) ;

Member Function Documentation

virtual void IImageShiftUtils::ShiftImageRowLeft ( uint16  shiftAmount, uint32  bufLen, uint8 *  inBuffer, uint8 *  overflowByte  )

pure virtual

Shift the image row to the left shiftAmount bits. Put the overflow in overflowByte (up to 8 bits of overflow, the extra falls off the edge)

Parameters

shiftAmount	- IN: The number of bits by which to shift the entire row to the left.
bufLen	- IN: The number of bytes in the inBuffer
inBuffer	- IN/OUT: A pointer to the buffer containing the image data to shift.
overflowByte	- OUT: pointer to a byte which will contain the overflow data.

virtual void IImageShiftUtils::ShiftImageRowRight ( uint16  shiftAmount, uint32  bufLen, uint8 *  inBuffer, uint8 *  overflowByte  )

pure virtual

Shift the image row to the right shiftAmount bits. Put the overflow in overflowByte (up to 8 bits of overflow, the extra falls off the edge)

Parameters

shiftAmount	- IN: The number of bits by which to shift the entire row to the right.
bufLen	- IN: The number of bytes in the inBuffer
inBuffer	- IN/OUT: A pointer to the buffer containing the image data to shift.
overflowByte	- OUT: pointer to a byte which will contain the overflow data.
