This means that it contains all current settings related to rendering, as well as the instructions for how to render the current frame. Instead, you use SDL_RenderPresent().

How to render text in SDL2 [ Stack Overflow ]?

How do you use fonts in SDL2?

To actually use fonts, we first rendered text to a surface, then passed it to a texture, and finally to the GPU. We used SDL_QueryTexture () to obtain the dimensions of the texture, so that we could render the text in exactly as much space as it needed.

What does SDL _ querytexture ( ) do in Visual Studio?

We used SDL_QueryTexture () to obtain the dimensions of the texture, so that we could render the text in exactly as much space as it needed. We also learned how we can set up our project to use the same path regardless of whether we’re running from Visual Studio or directly from the executable.

What is the basis of all text rendering methods?

The basis of all the text rendering methods is creating a SDL_Surface that contains the rendered text. TTF_RenderText_Solid()is the most straightforward way to do this. This function simply takes a TTF_Font pointer, a c-string to render, and a SDL_Color to render the text in. It returns a new SDL_Surface, or NULL on failure.
