Class RotatePrint

java.lang.Object

org.eclipse.nebula.paperclips.core.RotatePrint

All Implemented Interfaces:

Print

public final class RotatePrint
extends java.lang.Object
implements Print

A decorator print that rotates it's target by increments of 90 degrees.

Note: On Windows, this class depends on a bugfix available as of Eclipse build 3.2, release candidate 3 (2006-04-28). Prior to this release, using RotatePrint triggers the bug, causing the document to scale very large on paper. This bug only manifests itself on paper, not with on-screen viewing.

RotatePrints are horizontally and vertically greedy. Greedy prints take up all the available space on the page.

Constructor Detail

RotatePrint

public RotatePrint(Print target)

Constructs a RotatePrint that rotates it's target 90 degrees counter-clockwise.

Parameters:

target - the print to rotate.

RotatePrint

public RotatePrint(Print target,
                   int angle)

Constructs a RotatePrint.

Parameters:

target - the print to rotate.

angle - the angle by which the target will be rotated, expressed in degrees counter-clockwise. Positive values rotate counter-clockwise, and negative values rotate clockwise. Must be a multiple of 90.

Method Detail

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

getTarget

public Print getTarget()

Returns the print to be rotated.

Returns:

the print to be rotated.

getAngle

public int getAngle()

Returns the angle by which the target will be rotated (one of 0, 90, 180, or 270).

Returns:

the angle by which the target will be rotated.

iterator

public PrintIterator iterator(org.eclipse.swt.graphics.Device device,
                              org.eclipse.swt.graphics.GC gc)

Description copied from interface: Print

Returns a PrintIterator for laying out the contents of this Print. The iterator uses a snapshot of the print at the time this method is invoked, so subsequent changes to the Print will not affect the output of the iterator.

Specified by:

iterator in interface Print

Parameters:

device - the graphics device this Print will be drawn onto.

gc - the graphics context to be used for calculating layout and drawing the Print's contents.

Returns:

a PrintIterator for laying out the contents of this Print.
