      Returns:
      Default font to use, system-dependent
    • selectDefaultFont

      protected static Font[] selectDefaultFont(int fontSize)
      Returns the default font to use depending on the platform
      Parameters:
      fontSize - The size of the fonts to use
      Returns:
      Default font to use, system-dependent
    • getDefault

      public static AWTTerminalFontConfiguration getDefault()
      This is the default font settings that will be used if you don't specify anything
      Returns:
      An AWTTerminal font configuration object with default values set up
    • getDefaultOfSize

      public static AWTTerminalFontConfiguration getDefaultOfSize(int fontSize)
      Returns the default font settings except for a custom font size to use.
      Parameters:
      fontSize - Size of the font
      Returns:
      An AWTTerminal font configuration object with default values set up
    • filterMonospaced

      public static Font[] filterMonospaced(Font... fonts)
      Given an array of fonts, returns another array with only the ones that are monospaced. The fonts in the result will have the same order as in which they came in. A font is considered monospaced if the width of 'i' and 'W' is the same.
      Parameters:
      fonts - Fonts to filter monospaced fonts from
      Returns:
      Array with the fonts from the input parameter that were monospaced
    • newInstance

      public static AWTTerminalFontConfiguration newInstance(Font... fontsInOrderOfPriority)
      Creates a new font configuration from a list of fonts in order of priority. This works by having the terminal attempt to draw each character with the fonts in the order they are specified in and stop once we find a font that can actually draw the character. For ASCII characters, it's very likely that the first font will always be used.
      Parameters:
      fontsInOrderOfPriority - Fonts to use when drawing text, in order of priority
      Returns:
      Font configuration built from the font list
    • getFontForCharacter

      Font getFontForCharacter(TextCharacter character)
      Given a certain character, return the font to use for drawing it. The method will go through all fonts passed in to this AWTTerminalFontConfiguration in the order of priority specified and chose the first font which is capable of drawing character. If no such font is found, the normal fonts is returned (and probably won't be able to draw the character).
      Parameters:
      character - Character to find a font for
      Returns:
      Font which the character should be drawn using
    • getFontForCharacter

      private Font getFontForCharacter(String string)
    • getFontWidth

      public int getFontWidth()
      Returns the horizontal size in pixels of the fonts configured
      Returns:
      Horizontal size in pixels of the fonts configured
    • getFontHeight

      public int getFontHeight()
      Returns the vertical size in pixels of the fonts configured
      Returns:
      Vertical size in pixels of the fonts configured
    • isAntiAliased

      public boolean isAntiAliased()
      Returns true if anti-aliasing has been enabled, false otherwise
      Returns:
