func ExtractRange ¶

func ExtractRange(ctx context.Context, rs io.ReadSeeker, start, end, maxBytes int) ([]byte, error)

ExtractRange creates a PDF containing the zero-based half-open page range [start, end). A fresh source context is parsed on every call because pdfcpu's extraction mutates or shares named-destination structures between contexts.

func PageCount ¶

func PageCount(path string) (int, error)

func PageCountContext ¶

func PageCountContext(ctx context.Context, rs io.ReadSeeker) (int, error)

PageCountContext deliberately skips pdfcpu's full validation and optimization. Some valid-in-practice PDFs (for example, invoices with a bare /Annots Dict) are readable but rejected by the validator even in relaxed mode.
