Class BitmapFont

  • All Implemented Interfaces:
    TextFont
    public class BitmapFont
extends java.lang.Object
implements TextFont
    Describes a font that consists of a number of images. This type of font is generally used for environments that do not support rendering TrueType fonts, though the performance of bitmap fonts also tends to be better.

      • derive

        public BitmapFont derive​(int newSize)
        Description copied from interface: TextFont
        Returns a version of this font that uses the same font family and color, but has a different size.
        Specified by:
        derive in interface TextFont

      • derive

        public BitmapFont derive​(ColorRGB newColor)
        Description copied from interface: TextFont
        Returns a version of this font which uses the same font family and size, but has a different color.
        Specified by:
        derive in interface TextFont

      • deriveBold

        public BitmapFont deriveBold()
        Description copied from interface: TextFont
        Returns a bold version of this font. All all properties will be identical to the current font.
        Specified by:
        deriveBold in interface TextFont

      • draw

        public void draw​(GraphicsContext context,
                 java.lang.String text,
                 float x,
                 float y,
                 Align align,
                 AlphaTransform alpha)
        Draws a text with this bitmap font using the specified graphics context. This method will trigger several drawing operations to draw the various sub-images.

      • parseFNT

        public static BitmapFont parseFNT​(Image image,
                                  java.lang.String fntMetadata)
        Creates a bitmap font from an image and metadata parsed from a .fnt file using the AngelCode font format. AngelCode fonts can be created using various tools, such as libGDX Hiero (https://github.com/libgdx/libgdx/wiki/Hiero).
        Throws:
        MediaException - if the font metadata cannot be parsed.
