The _LOADFONT function returns a font handle for a TrueType font (.TTF).
- handle& = _LOADFONT (ttf_filename$, height[, "BOLD|, ITALIC|, UNDERLINE|, DONTBLEND|, MONOSPACE"])
- font_handle is the handle you want to use to represent the font. A return of -1 indicates a font loading failure.
- TTF_filename$ is the filename of truetype fonts only. Can include the path to the font file.
- Windows users should find TTF(True Type) font files in the C:\WINDOWS\FONTS folder.
- Height is the height of the font. Font heights can be found using _FONTHEIGHT.
- Style parameter(s) used, if any, are literal(in quotes) or variable text parameters. Monospace has limited font selections.
- You can pass different font styles using different predefined STRING variable lists.
- Font handles with values greater than 0 that are no longer needed should be freed using _FREEFONT. Font handle values of -1 (load failure) do not need to be freed! An [[ERROR Codes|error will occur if you try to free invalid handles
- Check that the font values are greater than 0 before using them or illegal function errors may occur!
Example 1: 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.
Note: 30 means each row of text (including vertical spacing) will be exactly 30 pixels high. This may make some program screens larger.
Example 2: In a 32-bit graphics mode you can alpha blend onto the background:
- Note: 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.
