Farbfeld

Farbfeld is suckless.org's lossless format: the word farbfeld, the width and height as big-endian 32-bit numbers, then 16-bit big-endian RGBA pixels, row by row. It reads and writes through the Egami.Formats.Extended package: register it with WithFarbfeld() or WithExtendedFormats() (Extended formats).

Reads	The whole format
Writes	Every raster as 16-bit RGBA, so nothing but metadata is lost
Natural pixel type	Rgba16
FormatInfo	FarbfeldFormat.Info: name Farbfeld, extension .ff, MIME type image/x-farbfeld

Rows stream from the input as they are asked for. Farbfeld files are often compressed with a general-purpose tool such as bzip2; Egami reads and writes the uncompressed file only.
