Field Detail

rotateContents

private boolean rotateContents

Holds value of property rotateContents.

Constructor Detail

PdfCopy

public PdfCopy(Document document, OutputStream os)

Constructor

Parameters: document os outputstream

Method Detail

add

public PdfIndirectReference add(PdfOutline outline)

add

PdfIndirectReference add(PdfPage page, PdfContents contents)

addAnnotation

public void addAnnotation(PdfAnnotation annot)

addFieldResources

private void addFieldResources(PdfDictionary catalog)

addPage

public void addPage(PdfImportedPage iPage)

Add an imported page to our output

Parameters: iPage an imported page

Throws: IOException, BadPdfFormatException

close

public void close()

Signals that the Document was closed and that no other Elements will be added.

The pages-tree is built and written to the outputstream. A Catalog is constructed, as well as an Info-object, the reference table is composed and everything is written to the outputstream embedded in a Trailer.

copyAcroForm

public void copyAcroForm(PdfReader reader)

Copy the acroform for an input document. Note that you can only have one, we make no effort to merge them.

Parameters: reader The reader of the input file that is being copied

Throws: IOException, BadPdfFormatException

copyArray

protected PdfArray copyArray(PdfArray in)

Translate a PRArray to a PdfArray. Also translate all of the objects contained in it

copyDictionary

protected PdfDictionary copyDictionary(PdfDictionary in)

Translate a PRDictionary to a PdfDictionary. Also translate all of the objects contained in it.

copyIndirect

protected PdfIndirectReference copyIndirect(PRIndirectReference in)

Translate a PRIndirectReference to a PdfIndirectReference In addition, translates the object numbers, and copies the referenced object to the output file. NB: PRIndirectReferences (and PRIndirectObjects) really need to know what file they came from, because each file has its own namespace. The translation we do from their namespace to ours is *at best* heuristic, and guaranteed to fail under some circumstances.

The general usage to stamp something in a page is:

 PdfImportedPage page = copy.getImportedPage(reader, 1);
 PdfCopy.PageStamp ps = copy.createPageStamp(page);
 ps.addAnnotation(PdfAnnotation.createText(copy, new Rectangle(50, 180, 70, 200), "Hello", "No Thanks", true, "Comment"));
 PdfContentByte under = ps.getUnderContent();
 under.addImage(img);
 PdfContentByte over = ps.getOverContent();
 over.beginText();
 over.setFontAndSize(bf, 18);
 over.setTextMatrix(30, 30);
 over.showText("total page " + totalPage);
 over.endText();
 ps.alterContents();
 copy.addPage(page);

Parameters: iPage an imported page

Returns: the PageStamp

Parameters: reader the reader of the document pageNumber which page to get

Returns: the page

isRotateContents

public boolean isRotateContents()

Getter for property rotateContents.

Returns: Value of property rotateContents.

Parameters: rotateContents New value of property rotateContents.
