Spaceward Graphics refers to the graphics file formats associated with a company named Spaceward, and its Satori family of graphics software for Windows, including Satori Paint.
- Spaceward file (.R) (a raster image format)
- Satori Canvas file (.CVS) (presumably a vector image format)
- Satori Raster file (.RIR)
For ".R" format, Image Alchemy's documentation implies that the image channels are stored in separate .R, .G, .B, and .A files. It's not clear if this is just a clerical error, or a reference to a different version of the format, or what. The Image Alchemy software actually only produces a .R file, containing all channels. And the available Satori Paint documentation only mentions the .R file.
