What is 7yuv

7yuv is is a tool for editing and visualizing raw graphics data and binary files. It is a valuable tool to assist development of games, video codecs, and general graphics programming.

A large number of surface formats is supported, including RGB and YUV pixel formats.

7yuv opens any file, regardless of type or size. Data is handled as raw binary, 7yuv allows "bit-true editing", i.e. no hidden data conversions are performed. Data can be edited in graphics, hex, or text mode.
