tga is a Go package for decoding and encoding TARGA image format.
It supports RLE and raw TARGA images with 8/15/16/24/32 bits per pixel, monochrome, truecolor and colormapped images. It also correctly handles origins, attribute type in extensions area and successfully passes TGA 2.0 conformance suite (http://googlesites.inequation.org/tgautilities).
Encoding an image doesn't involve conversion if it's image.Gray, image.RGBA or image.NRGBA. Other types are converted to image.NRGBA prior to encoding.
This package is fork from
github.com/ftrvxmtrx/tga. TARGA format does not have something at file start that can be passed as magic prefix, and so it should be registered after all others to put format to the end of list. It can be done bytga.RegisterFormat()call.
