llpr

llpr

llpr (low-level PDF reader) is intended to support applications which need fast access to raw PDF data streams.

usage:

• Instantiate a PDFDocument with PDFDocument::new which expects a PDFSource. Currently ByteSource and ByteSliceSource are supported which expect the PDF source to be a Vec<u8> and a &[u8] respectively. Other sources can be used by implementing the Source trait.

• Once you've created a PDFDocument the page_contents function will accept a page number (zero-based) and return a PageContents object. Use the page_count function to determine how many pages are in the document.

• Repeatedly call the next_object function on the PageContents object to retrieve PdfObjects.

A PDFObject is really low-level. See pdf_types.rs for a definition. This crate may be useful for building up higher level abstractions but can't help you if you're looking for something that can easily extract text or images from a PDF file.
