Classes
- Geometry
- Converts between a page as it is displayed and the PDF user space its content is drawn in.
- Mark
- A mark drawn on a page as a vector path: a tick, a cross, a dot, a line, a rectangle or an ellipse. For
ticking a box, striking something out or drawing a box around it on a form.
- Dictionary
- A PDF dictionary: keys are names, held without their slash, in the order they were read or set.
- Document
- An existing PDF, read far enough to revise it with an incremental update.
- EncryptedPdfException
- A PDF that is encrypted. New content added to it would have to be encrypted with the document's key,
which is not supported, so the document is refused rather than damaged.
- Filters
- Decodes stream data through the filters its dictionary names.
- IncrementalUpdate
- Revises a document by appending new and changed objects to it, leaving its original bytes untouched.
- Name

- Page

- Parser
- Reads PDF objects from bytes, following the object syntax of ISO 32000-1, section 7.3.
- PdfException

- PdfString
- A PDF string: its decoded bytes, and whether it was written in hex so it can be written back the same way.
- Reference

- Serializer
- Writes PDF values in PDF syntax.
- Stream
- A PDF stream: its dictionary and its data, still encoded with whatever `/Filter` the dictionary names.
- SignatureImage
- A signature as an image: anything GD can read, such as a PNG drawn with a transparent background or a
photo of a signature on paper.
- Signer
- Adds signature images, and marks such as ticks and lines, on top of the pages of an existing PDF.
