Now that we have learned how to render text to our HTML canvas element using SDL and Emscripten, we can take the next step and learn how to render sprites. The code used to render a sprite to the canvas is quite similar to the code that we used to render a TrueType font. We will still be using the virtual filesystem to generate a data file that contains the sprites we are using, but we will need a new SDL library to do this. We no longer need SDL2_ttf to load a TrueType font and render it to a texture. Instead, we need SDL2_image. We will show you how to change our call to emcc to include this new library a little later.
First, let's take a look at the new version of the SDL code that renders an image to our HTML canvas element instead of the text we rendered in the previous section:
#include <SDL2/SDL.h>
#include <SDL2/SDL_image.h>...
