draw_set_swf_aa_level(AA);
| 参数 | 描述 |
|---|---|
| AA | The anti-aliasing value to use from 0 to 1. |
返回： N/A（无返回值）
This function can be used to set the anti-aliasing (AA) level for SWF format vector sprites. This can be a real value from 0 to 1 and will "smooth" the edges of these sprites. Note that to see this effect, you must first have enabled AA using the function draw_enable_swf_aa().
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.
