NAME

       icetPhysicalRenderSize -- set the size of images that are rendered

Synopsis
       #include <IceT.h>

       void icetPhysicalRenderSize(   IceTInt	width,
				      IceTInt	height	);

Description
       Specify the size of images that are rendered with icetPhysicalRenderSize.  This is the size of image that is expected to be rendered by the
       draw callback (specified with icetDrawCallback).  The width and height are  captured  in  the  ICET_PHYSICAL_RENDER_WIDTH  and  ICET_PHYSI-
       CAL_RENDER_HEIGHT state variables.

       The  size of images that are rendered do not have to be the same size as the tile they are rendering so long as they are not smaller in any
       dimension. In fact, when rendering multiple tiles it can often save time to render larger images. Nevertheless,	by  default  the  physical
       render size is set to the size of the tiles in icetAddTile because this is the most common use case.

       When using the OpenGL rendering layer, the physical rendering size is overridden to the size of the OpenGL viewport in each call to icetGL-
       DrawFrame.

Errors
       None.

Warnings
       ICET_INVALID_VALUE
	       The width or height specified is smaller than that for the largest tile.

Bugs
       None known.
