Class GlyphBBoxOutlineConsumer

java.lang.Object
com.adobe.fontengine.font.GlyphBBoxOutlineConsumer
All Implemented Interfaces:
OutlineConsumer
public final class GlyphBBoxOutlineConsumer extends Object implements OutlineConsumer
A bezier consumer used to calculate the glyph bbox. This consumer can be used to calculate multiple bboxes, but the reset method must be called between each calculation.

Synchronization

This class is not synchronized. Multiple instances can safely coexist without threadsafety issues, but each must only be accessed from one thread (or must be guarded by the client).

  • Method Details

    • reset

      public void reset()
      resets the state of the consumer so that a new bbox can be calculated

    • setMatrix

      public void setMatrix(Matrix newMatrix)
      Description copied from interface: OutlineConsumer
      Tells the OutlineConsumer the matrix to be applied to subsequent points in order to get to a 1 ppem size. It is possible for setMatrix to be called multiple times for a single glyph. Each call replaces the previous matrix. It is guaranteed that setMatrix will be called prior to any other methods.
      Specified by:
      setMatrix in interface OutlineConsumer
      Parameters:
      newMatrix -

    • moveto

      public void moveto(double x, double y)
      Description copied from interface: OutlineConsumer
      Called to set a new currentpoint. If lineto or curveto was previously been called and was the most recent function called, an implied lineto should precede this move and should close the previous segment by connecting the last point in the most recent line/curve with the point that started the last segment.
      Specified by:
      moveto in interface OutlineConsumer
      Parameters:
      x - the x coordinate of the new currentpoint
      y - the y coordinate of the new currentpoint

    • lineto

      public void lineto(double x, double y)
      Description copied from interface: OutlineConsumer
      Called for a line. The line goes from the current point to (x, y). After this call, the currentpoint should be x,y
      Specified by:
      lineto in interface OutlineConsumer

    • curveto

      public void curveto(double x1, double y1, double x2, double y2)
      Description copied from interface: OutlineConsumer
      Called for a quadratic curve. The control points are the current point, (x2, y2), (x3, y3). After this call, the currentpoint should be x3, y3.
      Specified by:
      curveto in interface OutlineConsumer

    • curveto

      public void curveto(double x1, double y1, double x2, double y2, double x3, double y3)
      Description copied from interface: OutlineConsumer
      Called for a cubic curve. The control points are the current point, (x2, y2), (x3, y3), (x4, y4). After this call, the currentpoint should be x4, y4.
      Specified by:
      curveto in interface OutlineConsumer

    • getBBox

      public Rect getBBox()
      Returns the glyph bbox. This function can be called any time after the outlines have been run through this consumer.

    • endchar

      public void endchar()
      Description copied from interface: OutlineConsumer
      Called to signal the end of a glyph's outline. The last path will already be closed by the time this is called.
      Specified by:
      endchar in interface OutlineConsumer
