Key: PDFBOX-1104
URL: https://issues.apache.org/jira/browse/PDFBOX-1104
Project: PDFBox
Issue Type: Improvement
Components: Parsing, Utilities
Affects Versions: 1.6.0
Reporter: Jeremy Villalobos
Priority: Minor
The parser proposed just parses the minimal required from the PDF file
according to PDF specifications. A random page can be parsed without having to
parse the entire document first. Exist parsing code was used to transfer
existing bugfixes and compliance fixes to this parser.
The parser has been tested with the text extraction tool. But has not been
tested with the viewer or other pdf tools. Some tools may need to be recoded
to use the parser to prevent null pointer exceptions since the COSDocument will
contain null pointers for COSObjects that have not been parsed. For example,
the Current Text Extractor assumes the entire document is loaded. On this code
submission a modified text extractor is also included with the name
OnePagePDFTextStripper. The class has a function that will extract the text
from a PDPage submitted by the programmer.
