1 Introduction

CEPL.SDL2-TTF

A complementary library that adds a couple of simple helpers too ease making CEPL textures using the excellent sdl2-ttf.

API

#'init

Initialized sdl2-ttf only if not already initialized. Also checks that CEPL is initialized.

#'quit

Shuts down sdl2-ttf only if initialized

with-font

A helper macro that opens a font for the scope of the body

#'text-to-tex

This function takes:

• The string to render to a texture
• A font object
• A text color as a vector4 (defaults to (v! 255 255 255 0))

It returns a CEPL texture containing the text.

Example

(defun test ()
  (init)
  (with-font (font (asdf:system-relative-pathname
                    'sdl2-ttf-examples "examples/PROBE_10PX_OTF.otf"))
    (text-to-tex "hello world" font)))
