ODS Graphics problem with transparent background

[sinmathstat]

Hi

When I create a graph with transparent background with no borders, the output contains a thin non-transparent border.

ods listing gpath=".";
ods graphics / reset=all imagename="graphout" imagefmt=pdf border=off;

proc sgplot data=sashelp.class noopaque nowall;
	histogram age;
run;

ods listing close;

Any idea how to fix the problem?

Also add PAD=0:

proc sgplot data=sashelp.class noopaque nowall pad=0;

By default, there is a 10px pad around the graph that is not affected by the OPAQUE option.
