SDL without display

SDL Development

Hello

I would like to use SDL graphic functions in my program, but without
using SDL display and event functions. I tried it - I didn’t use
SDL_init and started creating surfaces, blitting between them,
accessing their raw data etc. Everything seemed to work. However,
I’ve found no mention about such use of SDL in the documentation
and I’m concerned - is it safe to do so? Has anyone tested such
a program?–

Semi-wild guess: isn’t it possible to use SDL_Init(SDL_INIT_VIDEO | …)
without having to SDL_SetVideoMode?

It’s possible, I’ve tried it either. However, it also inits event
handling and starts a thread. I’m not sure if it’s desirable,
because my program will do its own event and thread handling.–

I wonder, if you don’t desire a ‘platform independent video window’,
then why do you use SDL at all? What’s so special about SDL’s graphic
functions, that you want to use them? :slight_smile:

It’s the fastest graphics library I’ve found. Next one - imlib2

…and of course:

* It's a familiar API. (To most people around here.)

* It's lightweight, simple and extremely portable.

* There are add-on libs and code for loading, saving and
  processing images, for basic rendering etc.

* Most SDL hackers probably have a personal library of
  code that uses the SDL graphics API.

* To pre-render stuff using special FX coded for an SDL
  game, you can just use the game code as is.
