BOOL GpiSetMarkerBox(hps, psizfxBox)
HPS hps;             /* presentation-space handle                 */
PSIZEF psizfxBox;    /* address of structure with marker box size */
 
The GpiSetMarkerBox function sets the current marker-box attribute. The
marker box specifies the width and height of markers drawn by the GpiMarker
function.
 
If the attribute mode is AM_PRESERVE, the function saves the previous
marker-box attribute on the attribute stack when it sets the new marker box.
The previous marker-box attribute can be retrieved by using the GpiPop
function.
