I have a set of images that have been developed within Pixelmator Pro. I have been asked to provide these for use by people who are on both Windows and Linux systems. I want to provide files that have as much of the detail (like layers and such) that is in the normal .pxd files that can be input by other codes like Photoshop (and its relatives) and Gimp. Would an export as a Photoshop Document format (I'm assuming that will be a .psd file) be the best approach here?
