Class DoublePrintingTextGraphics

  • All Implemented Interfaces:
    StyleSet<TextGraphics>, TextGraphics

    public class DoublePrintingTextGraphics
    extends AbstractTextGraphics
    This TextGraphics implementation wraps another TextGraphics and forwards all operations to it, but with a few differences. First of all, each individual character being printed is printed twice. Secondly, if you call getSize(), it will return a size that has half the width of the underlying TextGraphics. This presents the writable view as somewhat squared, since normally terminal characters are twice as tall as wide. You can see some examples of how this looks by running the Triangle test in com.googlecode.lanterna.screen.ScreenTriangleTest and compare it when running with the --square parameter and without.

      • setCharacter

        public TextGraphics setCharacter​(int columnIndex,
                                         int rowIndex,
                                         TextCharacter textCharacter)
        Description copied from interface: TextGraphics
        Sets the character at the current position to the specified value, without using the current colors and modifiers of this TextGraphics.
        Parameters:
        columnIndex - column of the location to set the character
        rowIndex - row of the location to set the character
        textCharacter - Character data to set at the current position
        Returns:
        Itself
      • getCharacter

        public TextCharacter getCharacter​(int columnIndex,
                                          int rowIndex)
        Description copied from interface: TextGraphics
        Returns the character at the specific position in the terminal. May return null if the TextGraphics implementation doesn't support it or doesn't know what the character is.
        Parameters:
        columnIndex - Column to return the character for
        rowIndex - Row to return the character for
        Returns:
        The text character at the specified position or null if not available
      • getSize

        public TerminalSize getSize()
        Description copied from interface: TextGraphics
        Returns the size of the area that this text graphic can write to. Any attempts of placing characters outside of this area will be silently ignored.
        Returns:
        Size of the writable area that this TextGraphics can write too
