#3 Bug in TGAWriteImage

[Ricardo Dalcorsso Fodra]

I get an error when I run encode.c with a true color TGA. Somehow TGAWriteImage calls TGAWriteColorMap which calls TGAWrite(tga, buf, n, 1) with n=0 which returns 0 which is considered an error. I'm using libtga-1.0.1.

Image that encode.c doesn't handle.

Apparently the problem is in TGAReadImage. It is not setting data->cmap to NULL If the TGA is not color-mapped. Also TGAWriteImage checks for data->cmap, not TGA_IS_MAPPED.

Hey,
I forked this project on GitHub and fixed some bugs on the way.
My fork can run length encode (and decode) the attached file just fine.
