Effect tools
Bevel



Add volume on a sprite's shape, can be used on the sprite's opacity or on a selection.
Select multiple sprites from the sprite list to work apply the effect to all of them.
- Bevel width
- Width of the bevel, distance in pixels from the border of the sprite or selection
- Bevel height
- Height of the bevel, relative to the distance
- Smoothness
- Blur that is applied to the bevel, can be used to reduce artefacts or create soft surfaces.
Sprite borders are treated as tile borders. The bevel is added to bottom, left and right.


Sprite borders are treated as inside. The bevel is added only to the top.


Emboss
Add volume inside a sprite and / or make structure stand out.
This effect works on luminosity differences in the sprite's texture. Different brightness levels are considered to have different heights.
Can also be used on a selection.
Select multiple sprites from the sprite list to work apply the effect to all of them.



- Emboss height
- Height of the emboss, relative to the distance
