OCA is able to store different types of layers. For now, three types are supported :
vectorlayer. We hope to be able to support other types in the future like adjustment layers (at least with the most common effects) or masks.
|paintlayer||A bitmap containing an image|
|vectorlayer||Vectors forming an image, like an SVG file|
|grouplayer||A layer without frames/images but continaing other layers|
