| GetSpriteFilter |
| Mode = GetSpriteFilter(ThisSprite) |
| |
Parameters:
ThisSprite = The Sprite that you want to query
|
Returns:
Mode = Flag to set filtering mode the sprite should use (0=No filtering default, 1 = Bilinear) |
| |
The GetSpriteFilter is used to retrieve what filtering mode a sprite is using.
FACTS:
* Sprite filtering is disabled (set to 0) by default.
* When a filtered sprite is drawn, each pixel from the sprite image is blended with it's neighboring pixels. This blending calculation is heavy (on your CPU) to performs in real time, so it's best used sparingly. Pre-calculation is recommended.
* See SpriteDrawMode for more effects that can be combined with sprite filtering.
