Method Detail

adjustRectangleToAppearance

public static void adjustRectangleToAppearance(PDAnnotation annotation)

adjustRectangleToAppearance

public static void adjustRectangleToAppearance(PDAnnotation annotation,
                               PDAppearance appearance)

getAppearance

public static PDAppearance getAppearance(PDAnnotation annotation)

The PDAppearance for annotation. If no PDAppearance is yet available, a new one is created but NOT associated with the annotation. This behavior is intended to allow for dynamic appearance creation when rendering without changing the document itself.

Returns:

The PDAppearance for annotation.

getBorderColor

public static float[] getBorderColor(PDWidgetAnnotation annotation)

getBorderColorNegative

public static float[] getBorderColorNegative(PDWidgetAnnotation annotation)

getFillColor

public static float[] getFillColor(PDWidgetAnnotation annotation)

getFillColorNegative

public static float[] getFillColorNegative(PDWidgetAnnotation annotation)

getNextAnnotation

public static PDAnnotation getNextAnnotation(PDAnnotation annotation)

Returns the next annotation following annotation on the same page. Returns null if no annotation following annotation could be found or annotation is the last one on the page.

Parameters:

annotation -

Returns:

the next annotation or null

getNextAnnotationAllPages

public static PDAnnotation getNextAnnotationAllPages(PDAnnotation annotation)

Returns the next annotation following annotation in the whole document. Returns null if no annotation following annotation could be found in the document.

Parameters:

annotation -

Returns:

the next annotation or null

getPage

public static PDPage getPage(PDAnnotation annotation)

getPreviousAnnotation

public static PDAnnotation getPreviousAnnotation(PDAnnotation annotation)

Returns the annotation preceding annotation on the same page. Returns null if no annotation preceding annotation could be found or annotation is the first one on the page.

Parameters:

annotation -

Returns:

the preceding annotation or null

getPreviousAnnotationAllPages

public static PDAnnotation getPreviousAnnotationAllPages(PDAnnotation annotation)

Returns the annotation preceding annotation in the whole document. Returns null if no annotation preceding annotation could be found in the document.

Parameters:

annotation -

Returns:

the previous annotation or null

getStateChecked

public static COSName getStateChecked(PDWidgetAnnotation annotation)

Lookup the state that is used to represent "not off" in annotation.

Parameters:

annotation - The annotation to inspect for its "not off" state.

Returns:

Lookup the state that is used to represent "not off" in annotation.

isAnnotationSpec14

public static boolean isAnnotationSpec14(COSDictionary dict)

Checks a COSDictionary for being a subtyped known annotation as of Spec PDF 1.4

Parameters:

dict -

Returns:

true if known as of Spec PDF 1.4

isStateChecked

public static boolean isStateChecked(COSName state)

true if state represents a state that is not "/Off". "/Off" is the only legal way to switch of a toggle button, so anything else is "on".

Parameters:

state - The state to inspect if it is not "/Off".

Returns:

true if state represents a state that is not "/Off".

transform

public static void transform(CDSRectangle rect,
             CDSMatrix matrix,
             int rotation)
