kra-d is a port of libkra to D to support basic extraction of layer info and layer data from krita files.

Dependencies

dxml by jmdavis is required

• https://github.com/jmdavis/dxml
• https://code.dlang.org/packages/dxml

Parsing a document

To parse a Krita document, use parseDocument in kra.

KRA document = parseDocument("myFile.kra");

Extracting layer data from layer

To extract layer data (textures) from a layer use Layer.extractLayerImage()

KRA doc = parseDocument("myfile.kra");
foreach(layer; doc.layers) {
    
    // Skip non-image layers
    if (layer.type != LayerType.Any) continue;

    // Extract the layer image data.
    // The output RGBA output is stored in Layer.data
    layer.extractLayerImage();

    // write_image from imagefmt is used here to export the layer as a PNG
    write_image(buildPath(outputFolder, layer.name~".png"), layer.width, layer.height, layer.data, 4);
}
