java.lang.Objectde.intarsys.pdf.parser.PDFParser
de.intarsys.pdf.parser.COSDocumentParser
public class COSDocumentParser
A parser for PDF data streams.
The parser will create a object representation of the pdf document using COS level objects.
The parser is a one pass, read everything implementation.
Field Summary | |
---|---|
static int |
SEARCH_BUFFER_SIZE
use a buffer large than specified by the spec. we already had documents with whitespace padding > 1024 bytes! |

parseTrailer(de.intarsys.tools.randomaccess.IRandomAccess input)
parse the trailer section from the current stream position. see PDF Reference v1.4, chapter 3.4.4 File Trailer DocumentTrailer ::= "trailer" COSDict "startxref" COSNumber |
int |
searchLastStartXRef(de.intarsys.tools.randomaccess.IRandomAccess input)
Searches the offset to the first trailer in the last SEARCH_BUFFER_SIZE bytes of the document. |
