The _LOADFONT function returns a font handle for a TrueType font (.TTF).


Syntax

font_handle = _LOADFONT(ttf_filename$,height [,"BOLD,ITALIC,UNDERLINE,DONTBLEND,MONOSPACE")



Description

  • font_handle is the handle you want to use to represent the font.
  • ttf_filename$ is the filename of the truetype font.
  • height is the height of the font.


Examples

  • You need to know that if you are in a text mode (such as SCREEN 0 - the default) then you will only be able to use mono-spaced (fixed width) fonts.

f& =_LOADFONT("x:\cour.ttf",30,"monospace,italic,bold,underline") _FONT f& PRINT "Hello!"

Hello!

Note: 30 means each row of text (including vertical spacing) will be exactly 30 pixels high

  • In a 32-bit graphics mode you can alpha blend onto the background:

i& =_NEWIMAGE(800,600,32) SCREEN i& COLOR &HC0FFFF00,&H200000FF f& =_LOADFONT("x:\times.ttf",25) PRINT "Hello!"

Hello!


  • You can load a fixed width font file without using the "monospace" option and it will be treated as variable width. This can be useful because LOCATE treats the horizontal position as an offset in pixels for variable width fonts.
