Detailed Description

This class is used to write a PDF document. It acts as a wrapper to a real OutputStream, but is necessary for certain internal PDF structures to be built correctly.

Constructor & Destructor Documentation

gnu::jpdf::PDFOutput::PDFOutput (  OutputStream  os  )  throws IOException [inline]

This creates a PDF OutputStream Parameters: os  The output stream to write the PDF file to.

---

Member Function Documentation

void gnu::jpdf::PDFOutput::close (   )  throws IOException [inline, protected]

This closes the Stream, writing the xref table

void gnu::jpdf::PDFOutput::write (  PDFObject  ob  )  throws IOException [inline, protected]

This method writes a PDFObject to the stream. Parameters: ob  PDFObject Obeject to write Exceptions: IOException  on error

void gnu::jpdf::PDFOutput::writeblock (  int  firstid, Vector  block )  throws IOException [inline, protected]

Writes a block of references to the PDF file Parameters: firstid  ID of the first reference in this block block  Vector containing the references in this block Exceptions: IOException  on write error

Member Data Documentation

ByteArrayOutputStream gnu::jpdf::PDFOutput::baos [protected]

This is the OutputStream used to write each object to. We use a separate stream, because we need to keep track of how many bytes have been written for each object for the xref table to work correctly.

PDFObject gnu::jpdf::PDFOutput::infoID [protected]

This is used to track the /Info object (info)

int gnu::jpdf::PDFOutput::offset [protected]

This is the current position within the stream

Vector gnu::jpdf::PDFOutput::offsets [protected]

This vector contains offsets of each object

OutputStream gnu::jpdf::PDFOutput::os [protected]

This is the actual OutputStream used to write to.

PDFObject gnu::jpdf::PDFOutput::rootID [protected]

This is used to track the /Root object (catalog)
