java.lang.Object java.awt.font.NumericShaper
public final class NumericShaper
The NumericShaper class is used to convert Latin-1 (European) digits to other Unicode decimal digits. Users of this class will primarily be people who wish to present data using national digit shapes, but find it more convenient to represent the data internally using Latin-1 (European) digits. This does not interpret the deprecated numeric shape selector character (U+206E).
Instances of NumericShaper are typically applied as attributes to text with the
NUMERIC_SHAPING
attribute of the TextAttribute class. For example, this code snippet causes a TextLayout to shape European digits to Arabic in an Arabic context:
Map map = new HashMap(); map.put(TextAttribute.NUMERIC_SHAPING, NumericShaper.getContextualShaper(NumericShaper.ARABIC)); FontRenderContext frc = ...; TextLayout layout = new TextLayout(text, map, frc); layout.draw(g2d, x, y);
char[] text = ...; // shape all EUROPEAN digits (except zero) to ARABIC digits NumericShaper shaper = NumericShaper.getShaper(NumericShaper.ARABIC); shaper.shape(text, start, count); // shape European digits to ARABIC digits if precedingpreceedingtext is Arabic, or // shape European digits to TAMIL digits if precedingpreceedingtext is Tamil, or // leave European digits alone if there is no precedingpreceedingtext, or // precedingpreceedingtext is neither Arabic nor Tamil NumericShaper shaper = NumericShaper.getContextualShaper(NumericShaper.ARABIC | NumericShaper.TAMIL, NumericShaper.EUROPEAN); shaper.shape(text. start, count);
