Libraries.Game.Graphics.Fonts.TrueTypeFontTableDirectory

The TrueTypeFontTableDirectory class is used to maintain information about the various tables in a TrueType font file. This includes the name of the table, each specified by a 4 character tag, a checksum to verify the integrity of the table, an offset used to access the table in the font file, and the length of the table.

Example Code

use Libraries.Game.Graphics.Fonts.all
    use Libraries.Game.Game

    class Main is Game
        action Main
            StartGame()
        end

        action CreateGame
            TrueTypeFontTableDirectory directory
            directory:SetTag("glyf")
            directory:SetChecksum(011011)
            directory:SetOffset(100)
            directory:SetLength(500)
        end
    end

This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.

Example Code

Object o
        Object t
        integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)

This action determines if two objects are equal based on their hash code values.

Example Code

use Libraries.Language.Object
        use Libraries.Language.Types.Text
        Object o
        Text t
        boolean result = o:Equals(t)

This action returns the checksum of the table.

Example Code

use Libraries.Game.Graphics.Fonts.all
        use Libraries.Game.Game

        class Main is Game
            action Main
                StartGame()
            end

            action CreateGame
                TrueTypeFontTableDirectory directory
                output directory:GetChecksum()
            end
        end

This action gets the hash code for an object.

Example Code

Object o
        integer hash = o:GetHashCode()

This action returns the length of the table.

Example Code

use Libraries.Game.Graphics.Fonts.all
        use Libraries.Game.Game

        class Main is Game
            action Main
                StartGame()
            end

            action CreateGame
                TrueTypeFontTableDirectory directory
                output directory:GetLength()
            end
        end

This action returns the offset needed to access the table in the font file.

Example Code

use Libraries.Game.Graphics.Fonts.all
        use Libraries.Game.Game

        class Main is Game
            action Main
                StartGame()
            end

            action CreateGame
                TrueTypeFontTableDirectory directory
                output directory:GetOffset()
            end
        end

This action returns the name of the table.

Example Code

use Libraries.Game.Graphics.Fonts.all
        use Libraries.Game.Game

        class Main is Game
            action Main
                StartGame()
            end

            action CreateGame
                TrueTypeFontTableDirectory directory
                output directory:GetTag()   
            end
        end

This action sets the checksum of the table.

Example Code

use Libraries.Game.Graphics.Fonts.all
        use Libraries.Game.Game

        class Main is Game
            action Main
                StartGame()
            end

            action CreateGame
                TrueTypeFontTableDirectory directory
                directory:SetChecksum(011011) 
            end
        end

This action sets the length of the table.

Example Code

use Libraries.Game.Graphics.Fonts.all
        use Libraries.Game.Game

        class Main is Game
            action Main
                StartGame()
            end

            action CreateGame
                TrueTypeFontTableDirectory directory
                directory:SetLength(200)
            end
        end

This action sets the offset needed to access the table in the font file.

Example Code

use Libraries.Game.Graphics.Fonts.all
        use Libraries.Game.Game

        class Main is Game
            action Main
                StartGame()
            end

            action CreateGame
                TrueTypeFontTableDirectory directory
                directory:SetOffset(10)
            end
        end

This action sets the name of the table.

Example Code

use Libraries.Game.Graphics.Fonts.all
        use Libraries.Game.Game

        class Main is Game
            action Main
                StartGame()
            end

            action CreateGame
                TrueTypeFontTableDirectory directory
                directory:SetTag("glyf")    
            end
        end
