You have to invoke the SET-WINDOW-PARAM api with correct graphics window width to truncate the osd image.This cannot be handled in osd link.

another question is that i saw the osd window parameter about the width is noted like following:

UInt32 width;
/**< Width of window,
specified in pixels,
must be multiple of 4 in VCOP based OSD
must be multiple of 8 in DSP based OSD
*/

so if i set the osd window width is not multiple of 8 ,whether some errors will be happened

You will see some artifacts in the blended image if width is not multiple of 8
