This function returns a special pointer for the font texture page. This value can then be used in other draw functions, particularly in general drawing when using primitives as well as the Shader functions. You can get more information about the returned texture page using the different texture_ functions found here.
Argument Description font The index of the font to use.
Pointer (texture page ID)
tex = font_get_texture(fnt_Main);
The above code will get the texture pointer for the font indexed as "fnt_Main".
