Grabber::setWindowSize Method

bool setWindowSize( long width, long height );

true on success, false otherwise.

The size of the live video window can only be set, if Grabber::getDefaultWindowPosition returns false. If an application wants to alter the size of the live video window, it should call Grabber::setDefaultWindowPosition(false) first.

This example demonstrates how to set the size of the grabber's live video window.

long width  = 150;
long height = 100;
// Check whether the window position and size can be set
if( grabber.getDefaultWindowPosition() == true )
{
    printf("Default window position is enabled.\n");
    printf("It is not possible to set the window position and size now!\n");
}
else
{
    if( grabber.setWindowSize( width, height ) == true )
    {
        printf("New window size is %d %d\n", width, height);
    }
    else
    {
        printf("Failed to set the new window size!\n");
    }
}
