C++ (Cpp) SDL_Resize Examples

Example #1

File: WadImageCache.cpp Project: blezek/marathon-ios

SDL_Surface *WadImageCache::resize_image(SDL_Surface *original, int width, int height) const
{
	if (original) {
		if (original->w != width || original->h != height) {
			return SDL_Resize(original, width, height, false, 1);
		}
	}
	return NULL;
}

Example #2

File: sdl_resize.cpp Project: jonirons/alephone

SDL_Surface* SDL_Resize(SDL_Surface *src, float factor, bool free, int filter)
{
    if (factor > 100.0f) factor = 100.0f; //let's be reasonable...
    int new_w = (int)(src->w * factor),
        new_h = (int)(src->h * factor);
    if (new_w < 1) new_w = 1;
    if (new_h < 1) new_h = 1;

    return SDL_Resize(src, new_w, new_h, free, filter);
