Welcome to OpenRaster.org

This is the home of the Open Raster spec, version 0.0.6.

OpenRaster is file format specification for the exchange of layered raster images between image editors. OpenRaster was proposed in 2006 by Boudewijn Rempt and Cyrille Berger.

OpenRaster is an intentionally simple file format, similar to the Open Document file format: a zip file with an xml document describing the layer structure and a png image for each raster layer or an svg image for each vector layer.

Applications that support OpenRaster are Krita, GIMP, MyPaint and Scribus.
