Perform one-time, load-time operations on image data to procedurally generate pixel content.

A ScriptedInfo file with “.deimage” file extension would be interpreted as de::ImageFile. The .deimage would then describe various layering etc. actions — in a declarative way — to generate the output of the de::ImageFile (i.e, de::Image at runtime). ScriptedInfo would enable performing load-time scripts to determine the final output size/content.

Such a “.deimage” could be used wherever one would use a regular image file (assuming FS2 is used for loading the image data).

The “.deimage” could look something like:

size <512, 512>
format: rgba32

layer {
    filter = grayscale

    layer "background" {
        path = "someimage.png" 
    }

    layer "decal" {
        opacity = 0.25
        offset <25, 50>
        path = "decal.png" 
    }
}
