Libraries.Game.Graphics.Fonts.TrueTypeFontTableDirectory Documentation

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

Actions Documentation

Compare(Libraries.Language.Object object)

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.

Parameters

Return

integer: The Compare result, Smaller, Equal, or Larger.

Example

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

Equals(Libraries.Language.Object object)

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

Parameters

Return

boolean: True if the hash codes are equal and false if they are not equal.

Example

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

GetChecksum()

This action returns the checksum of the table.

Return

integer: Returns the checksum of the table.

Example

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

GetHashCode()

This action gets the hash code for an object.

Return

integer: The integer hash code of the object.

Example

Object o
integer hash = o:GetHashCode()

GetLength()

This action returns the length of the table.

Return

integer: Returns the length of the table.

Example

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

GetOffset()

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

Return

integer: Returns the offset needed to access the table in the font file.

Example

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

GetTag()

This action returns the name of the table.

Return

text: Returns the name of the table.

Example

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

SetChecksum(integer checkSum)

This action sets the checksum of the table.

Parameters

  • integer checkSum

Example

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

SetLength(integer lengthOfTable)

This action sets the length of the table.

Parameters

  • integer lengthOfTable: The length of the table.

Example

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

SetOffset(integer offsetIndex)

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

Parameters

  • integer offsetIndex: The offset needed to access the table in the font file.

Example

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

SetTag(text name)

This action sets the name of the table.

Parameters

  • text name: The name of the table.

Example

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
