Sample ras file

RAS (Sun Raster) is a bitmap format from Sun Microsystems' workstation era — old enough that it stores pixel data completely uncompressed, with no support for transparency, layers, or the metadata that later formats take for granted.

Its relevance today is almost entirely archival: legacy Unix systems, old scientific imaging pipelines, and archived documents from Sun workstation environments are the main places RAS still turns up. Most current image libraries include a RAS decoder more for completeness than active use.

If you're building or testing a format-conversion tool that claims broad legacy support, the sample below is useful specifically because RAS is obscure enough that many "supports everything" image libraries handle it incorrectly or not at all.
