No, since that's defined by the hardware and it is usually not changeable.
It is unclear what you are trying to do, but the easiest way to read image
files (TGA or any other format) is to use IMG_Load() from SDL_image, and
then convert them to a format quickly blittable to the screen by calling
SDL_DisplayFormat() or SDL_DisplayFormatAlpha()
