SDL + OpenGL Texture / Surface question

Recommended Posts

I solved my problem by using a whole different function to load my file because the other function wasn't working for alpha for some reason... Here is the new function I'm using in case anyone is having problems w/ IMG_Load and using alpha transparency.
GLuint load_texture(const char* file)
{
   SDL_Surface* surface = IMG_Load(file);
   GLuint texture;
   glPixelStorei(GL_UNPACK_ALIGNMENT,4);
   glGenTextures(1, &texture);
   glBindTexture(GL_TEXTURE_2D, texture);
   SDL_PixelFormat *format = surface->format;
   if (format->Amask)
   {
      gluBuild2DMipmaps(GL_TEXTURE_2D, 4,
         surface->w, surface->h, GL_RGBA,GL_UNSIGNED_BYTE, surface->pixels);
   }
   else
   {
      gluBuild2DMipmaps(GL_TEXTURE_2D, 3,
         surface->w, surface->h, GL_RGB, GL_UNSIGNED_BYTE, surface->pixels);
   }
   SDL_FreeSurface(surface);
   return texture;
}
