The plugin can load and save the following features of Photoshop .PSD files with no loss of fidelity:

    RGB images
    Color depth of 8 bits per channel
    Raster images with no use of vector features
    Layers, using the common blend modes
    (Optional) RLE compression

In this way, you can use the plugin to exchange work between Paint.NET and other programs. This is especially important since Paint.NET preserves layers only for the default .PDN format — other file formats are flattened on save. The .PSD file format thus offers the best way to preserve layers when editing an image in multiple graphics programs.
