NOTICE

PDFluent — Notice on License Composition

PDFluent is distributed across multiple Rust crates. Different crates within
the project carry different licenses depending on their origin and role.
Read this file together with the LICENSE file in the repository root.

============================================================================
OPEN-SOURCE FOUNDATION (permissive upstream licences)
============================================================================

The following crates are forks of upstream open-source libraries and remain
distributed under their original permissive licenses. They may be used
without a commercial license from PDFluent, subject only to the terms of
their respective open-source licenses:

  pdfluent-lopdf       MIT
                       (forked from lopdf, https://crates.io/crates/lopdf)

  pdfluent-cff         MIT OR Apache-2.0
                       (forked from cff-parser)

  pdfluent-ccitt       Apache-2.0 OR MIT
                       (forked from hayro-ccitt by Laurenz Stampfl,
                        https://github.com/LaurenzV/hayro)

  pdfluent-jbig2       Apache-2.0 OR MIT
                       (forked from hayro-jbig2)

  pdfluent-jpeg2000    Apache-2.0 OR MIT
                       (forked from hayro-jpeg2000)

  pdf-syntax           Apache-2.0 OR MIT
                       (forked from hayro-syntax)

  pdf-interpret        Apache-2.0 OR MIT
                       (forked from hayro-interpret)

  pdf-render           Apache-2.0 OR MIT
                       (substantially extended fork of hayro, co-authored by
                        Laurenz Stampfl)

  pdf-font             Apache-2.0 OR MIT
                       (substantially extended fork merging hayro-font,
                        hayro-cmap and hayro-postscript, co-authored by
                        Laurenz Stampfl)

pdf-render and pdf-font carry substantial PDFluent work on top of the upstream
code. That does not move them across the line: they are derivative works of an
Apache-2.0 OR MIT original whose relicensing is prohibited, so they stay
Apache-2.0 OR MIT here, however far they are extended.

The original copyright notices for these upstream projects are preserved
in their respective source files and in the THIRD_PARTY_LICENSES.txt file.

============================================================================
DUAL-LICENSED COMPONENTS (AGPL-3.0-only OR PDFluent Commercial Licence)
============================================================================

The following crates are PDFluent's own work and are available under two
licences, at your option: the GNU AGPLv3, or the PDFluent Commercial Licence.
See the LICENSE file in this repository.

The AGPL is the complete product; no feature is withheld and nothing expires.
It asks that you offer your users the corresponding source under the same
licence if you convey the software or let them use a modified version over a
network. The commercial licence is the alternative for anyone who cannot do
that. See https://pdfluent.com/sdk/pricing.

  pdfluent             — the unified facade SDK
  pdf-engine           — orchestration and document model
  pdf-manip            — page-level manipulation (merge, split, rotate, etc.)
  pdf-redact           — content redaction
  pdfluent-sign        — digital signatures (PAdES, S/MIME)
  pdf-compliance       — PDF/A, PDF/UA, PDF/X validation and conversion
  pdfluent-extract     — text and image extraction
  pdfluent-forms       — AcroForm support
  pdf-annot            — annotations
  pdf-docx             — DOCX export
  pdf-xlsx             — XLSX export and table extraction
  pdf-pptx             — PowerPoint PPTX export
  pdf-invoice          — FDF/XFDF form data exchange and ZUGFeRD/Factur-X
  pdf-text-format      — text run formatting
  pdf-standard-fonts   — the Standard 14 font programs, compiled in
                         (the font programs themselves come from PDFium,
                          © 2014 Foxit Software Inc., BSD-3-Clause; that
                          notice ships inside the crate)
  pdf-ocr              — OCR integration
  pdf-xfa              — XFA processing engine
  xfa-dom-resolver     — XFA DOM
  xfa-layout-engine    — XFA layout engine
  xfa-js-sandboxed     — sandboxed JavaScript runtime for XFA scripts
  formcalc-interpreter — FormCalc evaluation
  xfa-json             — XFA JSON conversion

The Software produces the same output whether or not a commercial licence is
held: there is no licence key, nothing is withheld and no marker is added
(#226). Documents carry "PDFluent" in the PDF Producer entry and in XMP
metadata, which either licence lets you replace or remove in your own build.
See LICENSE-COMMERCIAL §4.

============================================================================
EVALUATION
============================================================================

Every crate above may be evaluated with nothing asked in return: no key, no
sign-up, no time limit. There is no separate evaluation build -- what you
install is the whole product, under the AGPLv3.

What an evaluation ends with is a choice of licence rather than an expiry:
the AGPL and its obligation to offer your users the corresponding source, or
the commercial licence, which removes that obligation. The commercial route
is self-service and yearly -- Commercial EUR 999 per organisation, OEM Startup
EUR 2,499 and OEM EUR 9,999 per product (LICENSE-COMMERCIAL §2a). Nothing is
delivered but an order confirmation and a licence document; there is no key.
