assets:low-level_image_filtering
Low-level image filtering
The Doomsday 2 file system supports basic image filtering operations. This means that image files associated with assets can be modified when they are loaded. The mechanism works with all assets.
To apply a filter operation, the following syntax is used:
filePath/filterOperation
For example:
path = "images/heights.png/HeightMap.toNormals"
- File path is: images/heights.png
- Filter operation is: “HeightMap.toNormals”
It is also possible to chain multiple operations:
path = "images/heights.png/HeightMap.toNormals/Multiply:mask.png"
That would first load images/heights.png, then apply the heightmap-to-normals conversion, and finally multiply with images/mask.png.
| Operation | Description |
|---|---|
| Color.desaturate | Desaturate colors of the image (convert to grayscale). |
| HeightMap.toNormals | Convert a grayscale heightmap to an RGB normal map. |
| Multiply:(path) | Multiply RGBA channels separately by the RGBA values from another image. (path) is relative to the first file. |
