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.

Because the TGA file format does not specify "magic bytes", the normal Go image loading
mechanism tries to open every file as if it were a TGA file. Thus, this library does
not play nice with loading other formats according to the
[]documentation](http://blog.golang.org/go-image-package). To address this, the
registration of the encoder/decoder is not done in an init() function, rather to use
the standard Go image loading paradigm, a call to tga.RegisterFormat() is required.
