Special for interface. same as render2D but clip the quads to xmin,ymin/xmax,ymax. NB: behavior is same as render2D with: Hotspot = bottomLeft, scaleX=1, scaleZ=1, rotateY=0, useScreenAR43= false, roundToNearestPixel= false Additionnaly, this method don't render directly to the driver but add primitives to a <a class="el" href="a03324.html">CRenderStringBuffer</a> Use the method <a class="el" href="a03324.html#NL3D_1_1CRenderStringBuffera1">CRenderStringBuffer::flush()</a> to flush it all.

StringLine is the size from bottom of the whole string image to the hotspot in pixels. for instance if the hotspot is bottomLeft the imaginary line of the string "bpc" is under the b, under the loop of the p but over the leg of the p. So StringLine is a positive value in this case. It may be a negative value for the string "^" for example.
