- * unsigned char *src_ptr, int src_width, int src_height, int src_pitch,
- * int src_x, int src_y, int src_dx, int src_dy);
- * Input:
- * dest_ptr - pointer to a destination buffer
- * dest_width, dest_height - width/height of the destination image (pixels)
- * dest_pitch - pitch of the dest. buffer (in bytes; <0 - if bottom up image)
- * dest_x, dest_y, dest_dx, dest_dy - destination rectangle (pixels)
- * src_ptr - pointer to an input image
- * src_width, src_height - width/height of the input image (pixels)
- * src_pitch - pitch of the source buffer (in bytes; <0 - if bottom up image)
- * src_x, src_y, src_dx, src_dy - source rectangle (pixels)
- * Returns:
- * 0 - if success; -1 if failure.
- * Notes:
- * a) In all cases, pointers to the source and destination buffers must be
- * DWORD aligned, and both pitch parameters must be multiple of 4!!!
- * b) Converters that deal with YUV 4:2:2, or 4:2:0 formats may also require
- * rectangle parameters (x,y,dx,dy) to be multiple of 2. Failure to provide
- * aligned rectangles will result in partially converted image.
- * c) Currently only scale factors of 1:1 and 2:1 are supported; if the rates
- * dest_dx/src_dx & dest_dy/src_dy are neither 1, or 2, the converters
- * will fail.
