public class PDFShapeCmd
extends PDFCmd

Encapsulates a path. Also contains extra fields and logic to check for consecutive abutting anti-aliased regions. We stroke the shared line between these regions again with a 1-pixel wide line so that the background doesn't show through between them.

Constructors

Constructor	Description
PDFShapeCmd(GeneralPath gp, int style, boolean autoAdjustStroke)	create a new PDFShapeCmd and check it against the previous one to find any shared edges.

Method Summary

Constructor Details

PDFShapeCmd

public PDFShapeCmd(GeneralPath gp,
 int style,
 boolean autoAdjustStroke)

create a new PDFShapeCmd and check it against the previous one to find any shared edges.

Parameters:

gp - the path

style - the style: an OR of STROKE, FILL, or CLIP. As a convenience, BOTH = STROKE | FILL.

Method Details

execute

public Rectangle2D execute(PDFRenderer state)

perform the stroke and record the dirty region

Specified by:

execute in class PDFCmd

Parameters:

state - the current graphics state; may be modified during execution.

Returns:

the region of the page made dirty by executing this command or null if no region was touched. Note this value should be in the coordinates of the image touched, not the page.

checkOverlap

private GeneralPath checkOverlap(PDFRenderer state)

Check for overlap with the previous shape to make anti-aliased shapes that are near each other look good

getPoints

private int getPoints(GeneralPath path,
 float[] mypoints,
 AffineTransform at)

Get an array of 16 points from a path

Returns:

the number of points we actually got

getDetails

public String getDetails()

Get detailed information about this shape

Overrides:
