| Flattener | | public class Flattener extends PathSink (Code) | | The Flattener class rewrites a general path, which
may include curved segments, into one containing only linear
segments suitable for sending to a LineSink.
Curved segments specified by quadTo and
curveTo commands will be subdivided into two pieces.
When the control points of a segment lie sufficiently close
togther, such that max(x_i) - min(x_i) < flatness and
max(y_i) - min(y_i) < flatness for a user-supplied
flatness parameter, a lineTo command is
emitted between the first and last points of the curve.

| Constructor Summary | |
| public | Flattener()
Empty constructor. | | public | Flattener(LineSink output, int flatness)
Constructs a Flattener that will rewrite any
incoming quadTo and curveTo commands
into a series of lineTo commands with maximum X
and Y extents no larger than the supplied flatness
value. |

| Flattener | | public Flattener(LineSink output, int flatness)(Code) | | Constructs a Flattener that will rewrite any
incoming quadTo and curveTo commands
into a series of lineTo commands with maximum X
and Y extents no larger than the supplied flatness
value. The flat segments will be sent as commands to the given
LineSink.
Parameters:
output - a LineSink to which commandsshould be sent.
Parameters:
flatness - the maximum extent of a subdivided output linesegment, in S15.16 format. |
