How to Use FPDI PDF Parser

$parser = new PdfParser('path/to/file.pdf');

This will parse the PDF file and store its information in the parser object. You can then access various properties and methods of the parser object, such as:

$parser->getStreamReader(): returns the stream reader instance that handles the reading of the PDF file.

$parser->getTokenizer(): returns the tokenizer instance that splits the PDF file into tokens.

$parser->getCrossReference(): returns the cross-reference instance that manages the object references in the PDF file.

$parser->getObjects(): returns an array of all read objects from the PDF file.

$parser->getPdfVersion(): returns the version number of the PDF file.

$parser->getFileHeader(): returns the file header of the PDF file.

$parser->getFileHeaderOffset(): returns the offset to the file header in the PDF file.

You can also use the parser object to get specific objects from the PDF file by their object number and generation number:

$object = $parser->getObject(1, 0);

This will return an instance of PdfIndirectObject that represents the object with number 1 and generation 0 in the PDF file. You can then access its properties and methods, such as:

$object->getNumber(): returns the object number.

$object->getGeneration(): returns the generation number.

$object->getValue(): returns the value of the object as a PdfType instance.

$object->getStream(): returns an instance of PdfStream if the object has a stream dictionary and stream data.
