StellarCanvas — This StellarCanvas manual is adapted from the Krita documentation. Because StellarCanvas includes HarmonyOS-specific changes, some features, interface details, and behavior may differ from this manual.

*.ora¶

.ora, or the Open Raster format, is an interchange format. It was designed to replace *.psd as an interchange format, as the latter isn’t meant for that. Like *.kra it is loosely based on the Open Document structure, thus a ZIP file with a bunch of XMLs and PNGs, but where StellarCanvas’s internal file format can sometimes have fully binary chunks, .ora saves its layers as *.png making it fully open and easy to support.

As an interchange format, it can be expected to be heavy and isn’t meant for uploading to the internet.
