  • public class DotMapperConfiguration
extends Object
    Provides a configuration for a DotMapper.

    • Method Detail

      • builder

        public static DotMapperConfiguration.Builder builder()
        Creates a new builder with the default configuration. The default configuration maps 8-dot unicode patterns to 6-dot unicode patterns: Dots 7 and 8 of the first cell are shifted to dots 1 and 4 of the first cell of the following line. Dots 1 and 4 of the first cell of the second line are subsequently shifted to dots 2 and 5 of the first cell of the second line and so on.
        Returns:
        returns a new builder

      • getBitMap

        public int[] getBitMap()
        Gets the bit pattern mapper. This map defines how input dots in a braille cell are translated to a bit in the output character's bit pattern. When an input dot is present, the corresponding bit in the output character should be set.
        Returns:
        the bit map

      • getCellHeight

        public int getCellHeight()
        Gets the output cell height. This represents the height of the window used to construct an output character from the dot grid.
        Returns:
        the cell height

      • getCellWidth

        public int getCellWidth()
        Gets the output cell width. This represents the width of the window used to construct an output character from the dot grid.
        Returns:
        the cell width

      • getInputCellHeight

        public int getInputCellHeight()
        Gets the height of the input cell. If the value is less than 4, some dots at the bottom of the cell will be ignored.
        Returns:
        the input cell height

      • getBaseCharacter

        public char getBaseCharacter()
        Gets the base character. This character is used when all "bits" in the pattern are zero.
        Returns:
        the base character
