Adds a configurable maxPages field to PDFParserConfig (default -1, no limit). When set, AbstractPDF2XHTML.processPages() breaks out of the page loop early, avoiding all text extraction, font mapping, and content stream work for pages beyond the limit. Validated on a 738-page PDF: parsing 5 pages is 13x faster than a full parse.
Adds maxPages to the PDF parser full config example, which is included in docs/configuration/parsers/pdf-parser.adoc and validated by ConfigExamplesTest#testPdfParserFullConfig.

Should we do page range instead? pageStart, pageEnd, with 1 index? That would allow iterating through in chunks. I'm ok with this as is. wdyt? |
