Interface OutlineConsumer

All Known Subinterfaces:

HintedOutlineConsumer

All Known Implementing Classes:

AutoColor, GlyphBBoxOutlineConsumer, NonOverlappingOutlineConsumer, OutlineConsumerAdapter, StemFinder, Type1CStringConsumerDefault, Type2CStringGenerator

public interface OutlineConsumer

Receives events for unhinted beziers representing glyphs. There is one event for lines, one event for curves, and one event for moves. The path will be closed after the final event. The fill will be to the left when walking in the direction of the path unless the glyph is malformed. The coordinates are in the design space of the font.

Method Summary

Modifier and Type	Method and Description
void	curveto(double x2, double y2, double x3, double y3) Called for a quadratic curve.
void	curveto(double x2, double y2, double x3, double y3, double x4, double y4) Called for a cubic curve.
void	endchar() Called to signal the end of a glyph's outline.
void	lineto(double x, double y) Called for a line.
void	moveto(double x, double y) Called to set a new currentpoint.
void	setMatrix(Matrix newMatrix) Tells the OutlineConsumer the matrix to be applied to subsequent points in order to get to a 1 ppem size.

Method Detail

setMatrix

void setMatrix(Matrix newMatrix)

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.

Parameters:

newMatrix -

moveto

void moveto(double x,
            double y)

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.

Parameters:

x - the x coordinate of the new currentpoint

y - the y coordinate of the new currentpoint

lineto

void lineto(double x,
            double y)

Called for a line. The line goes from the current point to (x, y). After this call, the currentpoint should be x,y

curveto

void curveto(double x2,
             double y2,
             double x3,
             double y3,
             double x4,
             double y4)

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.

curveto

void curveto(double x2,
             double y2,
             double x3,
             double y3)

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.

endchar

void endchar()

Called to signal the end of a glyph's outline. The last path will already be closed by the time this is called.
