Method Detail

getMetadata

public Metadata getMetadata()

Description copied from interface: MetadataProvider

Return the exposed meta-data or null if no meta-data is available. An object being a MetadataProvider is not required to provide a non-null meta-data.

Specified by:

getMetadata in interface MetadataProvider

Overrides:

getMetadata in class AbstractPageSegment

Returns:

the metadata document or null

setSource

public void setSource(PageSegmentSource source)

Overrides:

setSource in class AbstractPageSegment

isAuxiliary

public boolean isAuxiliary()

Description copied from interface: PageSegment

Return whether this PageSegment is in some way "auxiliary". Auxiliary page segments contain additions to the main page segment, but rarely represent the main page content in their own right. Currently most page segments are non-auxiliary except for the AnnotationPageSegment.

Specified by:

isAuxiliary in interface PageSegment

Overrides:

isAuxiliary in class AbstractPageSegment

Returns:

true if this page segment is auxiliary, false if it represents "main" page content.

addPageSegment

public void addPageSegment(PageSegment segment,
                           AffineTransform tx)

Place the given PageSegment into the composition using the given transform.

Parameters:

segment - the page segment to be placed

tx - the affine transform to be used

addPageSegment

public void addPageSegment(PageSegment segment,
                           AffineTransform tx,
                           Shape clipPath)

Place the given PageSegment into the composition using the given transform. Apply the given clip path to the placed page segments to cut away undesired parts. The clip path is interpreted in the coordinate system of the placed page segment, i.e. before the transform is applied.

Parameters:

segment - the page segment to be placed

tx - the affine transform to be used

clipPath - the clip path to be applied or null if no clipping shall be applied.

Throws:

IllegalArgumentException - if segment or tx is null.

doCreateCacheableRendering

protected AbstractPageSegment.CacheableRendering doCreateCacheableRendering()
                                                                     throws JadiceException

Overrides:

doCreateCacheableRendering in class AbstractPageSegment

Throws:

JadiceException

isOpaqe

public boolean isOpaqe()

Set whether this page segment is opaque (all white) regardless of whether the whole bounds are taken up by component segments or not.

Returns:

whether this page segment is opaque

setOpaqe

public void setOpaqe(boolean clearBackground)

Set whether this page segment is opaque (all white) regardless of whether the whole bounds are taken up by component segments or not.

Parameters:

clearBackground -

fireModified

protected void fireModified()

Description copied from class: AbstractMutablePageSegment

Fire a notification about a general change to the page segment. Please consider firing a more specialized one, indicating the actual damage region.

Overrides:

fireModified in class AbstractMutablePageSegment

getSegments

protected List<AbstractCompositePageSegment.TransformedElement> getSegments()

Warning: Just for internal use. As the returned segments represent the actual segments, changes may lead to inconsistencies.

Returns:
