J2K in het kort
J2K
JPEG 2000 arrived as a major standards effort to improve on classic JPEG, but its practical adoption concentrated in specialist domains rather than in the universal browser-and-camera role held by JPEG.
TGA in het kort
TGA
Before today's relatively small set of mainstream consumer image formats dominated everyday use, desktop software, workstations, GUI systems, and early graphics tools produced many specialized raster formats with local importance.
