From 1f6eb1fc61d2cc0cca54a79c1516432f09c86313 Mon Sep 17 00:00:00 2001 From: Ray San Date: Mon, 6 Feb 2017 18:48:56 +0100 Subject: Moved raylib webpage to docs folder raylib webpage has been completely reorganized and moved from gh-pages (a pain to work with) to docs folder. Useless libs have been removed, webs have been renamed, etc. Now it would be easier (hopefully) to update webpage. :) --- docs/examples/src/text_ttf_loading.c | 130 +++++++++++++++++++++++++++++++++++ 1 file changed, 130 insertions(+) create mode 100644 docs/examples/src/text_ttf_loading.c (limited to 'docs/examples/src/text_ttf_loading.c') diff --git a/docs/examples/src/text_ttf_loading.c b/docs/examples/src/text_ttf_loading.c new file mode 100644 index 00000000..918209dd --- /dev/null +++ b/docs/examples/src/text_ttf_loading.c @@ -0,0 +1,130 @@ +/******************************************************************************************* +* +* raylib [text] example - TTF loading and usage +* +* This example has been created using raylib 1.3.0 (www.raylib.com) +* raylib is licensed under an unmodified zlib/libpng license (View raylib.h for details) +* +* Copyright (c) 2015 Ramon Santamaria (Ray San - raysan@raysanweb.com) +* +********************************************************************************************/ + +#include "raylib.h" + +int main() +{ + // Initialization + //-------------------------------------------------------------------------------------- + int screenWidth = 800;
