3.3.13 IMG_isXV

int IMG_isXV(SDL_RWops *src)


If the XV format is supported, then the image data is tested to see if it is readable as an XV thumbnail, otherwise it returns false (Zero).

Returns: 1 if the image is an XV thumbnail and the XV format support is compiled into SDL_image. 0 is returned otherwise.

// Test sample.xv to see if it is an XV thumbnail
SDL_RWops *rwop;
rwop=SDL_RWFromFile("sample.xv", "rb");
	printf("sample.xv is an XV file.\n");
	printf("sample.xv is not an XV file, or XV support is not available.\n");
