def Convert(self,srcBuffer,srcBufferOffset,destBuffer,destBufferOffset,width,height,inAlign,outAlign):
srcBuffer
A byte array containing the input buffer.
srcBufferOffset
Offset to the first byte of the srcBuffer data buffer.
destBuffer
A byte array that will hold the converted data.
destBufferOffset
Offset to the first byte of the destBuffer data buffer.
width
Width of pixels to be processed.
height
Height of pixels to be processed.
inAlign
Each scanline in the input buffer is a multiple of inAlign bytes.
outAlign
Each scan line in the output buffer is a multiple of outAlign bytes.
Conversion is done by setting the active method value specified in ActiveMethod property. To change the active method, use SetParameters method. To convert to the Y41P type the input image width must be multiple of 8
