描述

This function can be used to get the anti-aliasing (AA) level for SWF format vector sprites. The return value will between 0 and 1 and shows how "smooth" the edges of these sprites will be drawn. You can set the AA level using the function draw_set_swf_aa_level().

例如：

if draw_get_swf_aa_level() == 0
   {
   draw_enable_swf_aa(true);
   draw_set_swf_aa_level(0.5);
   }

The above code will check the AA value for SWF format sprites, and if it is 0 it enables AA and sets the value to 0.5.
