      • getHPIAdjustedFontSize

        private static int getHPIAdjustedFontSize​(int baseFontSize)

      • selectDefaultFont

        protected static java.awt.Font[] selectDefaultFont()
        Returns the default font to use depending on the platform
        Returns:
        Default font to use, system-dependent

      • selectDefaultFont

        protected static java.awt.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 java.awt.Font[] filterMonospaced​(java.awt.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​(java.awt.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

        java.awt.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
