Since version 6.2, graphic exporter filter honored AntiAliasing property passed in FilterData [1]. However, since 7.5, it has no effect on the output. The code provided in [1] produces AAed bitmap, irrespective of the value passed in the AntiAliasing property. Regression after commit 444bf8710d5da7b584fbcb94693e4ed8d2e29297.
