This function creates a dgs font element that can be used in dgsSetFont.

Successful font creation is not guaranteed, and may fail due to hardware or memory limitations.

The font file should be in the dgs folder.

Syntax

element dgsCreateFont ( string filepath [, int size=9, bool bold=false, string quality="proof" ] )

Required Arguments

  • filepath: the name of the file containing the font

Optional Arguments

  • size: size of the font
  • bold: flag to indicate if the font should be bold
  • quality: the font quality
    • "default": not the actual default
    • "draft"
    • "proof": the default
    • "nonantialiased"
    • "antialiased"
    • "cleartype"
    • "cleartype_natural"

Returns

Returns a DGS font element if successful, false if invalid arguments were passed to the function, or there is insufficient resources available.

You should always check to see if this function has returned false.

Example

-- Display a dgs label
local myLabel = dgsCreateLabel( 100, 300, 400, 50, "DGS label", false )

-- Use 'toggle' command to switch custom font on and off
addCommandHandler( "toggle",
    function()
        if not myFont then
            myFont = dgsCreateFont( "segoeui.ttf", 20 )  -- Create DGS custom font
            dgsSetFont( myLabel, myFont )                -- Apply font to a widget
        else        
            destroyElement( myFont )                     -- Destroy custom font
            myFont = nil
        end
    end
)
