Feature Request: Full TGA file spec format support
Proposal
- add full TGA 2 specification support with adding xTGA as a submodule
| Library | TGA 2 support |
|---|---|
| xTGA by @xNWP | full |
| aseprite by @aseprite | incomplete |
| sail by @HappySeaFox | incomplete |
| libimago by @jtsiomb | incomplete |
| Boost.GIL by @boostorg | incomplete |
It is a good idea to integrate some lightweight image library to save screenshots. But i am afraid, that both your suggestions are not so good - they have too few stars. Try to find more popular library.
Also, it is possible to use not TGA, but PNG for screenshots. In such case it is even possible to build with system LibPNG. But such dependency should be optional, in order to build the project on Windows without libPNG installed.
In my opinion it is better to stay with TGA for screenshots which supports the desired palette and flip, because the main image format the game uses is TGA. The only existing library supporting full TGA 2 format is xTGA. Adding it as a submodule doesn't introduce any unnecessary dependencies.

That's the funniest criterion for choosing a library I've heard :) Btw the link to libimago above is mangled, here's a the correct link: https://github.com/jtsiomb/libimago
Having said that, you don't need a library to write a TGA image, it's dead simple, especially if you don't use RLE.
Edit: oh and I just noticed, my library doesn't save TGA files (EDIT2: now it does), I apparently never bothered to implement that, only reads them, so it doesn't do what you need I'm afraid... well I guess it's time I added the missing write routine, why not. Thanks for the reminder!
