Example

Remarks

buffer contains the buffer containing a line from the original image to be resized. Your code must allocate the buffer and copy the data into it before calling this method.

The same buffer holds the data before and after it is resized. Therefore, the buffer must be big enough to hold whichever is larger. (The original line is larger when reducing an image; the resulting line is larger when enlarging the image.)

Before calling this function, you must call the Start method.

When all lines have been processed, you must call the Stop method.
