This sample shows how to use PDFNet Convert Add-on (i.e. 'pdftron.PDF.Convert' namespace) for direct, high-quality conversion between PDF, XPS, EMF, SVG, TIFF, PNG, JPEG, and other image formats. The sample also shows how to convert any printable document (e.g. Word, RTF, MS Office, DXF, DWG, etc) to PDF or XPS using a universal document converter.


Digitally sign PDF files

Demonstrates the basic usage of high-level digital signature API to digitally sign and/or certify PDF documents.


Build, write, embed elements in PDF pages

Illustrates how to use PDFNet page writing API, how to embed fonts and images and how to copy graphical elements from one page to another.


PDF editor (programmatic)

The sample code shows how to edit the page display list and how to modify graphics state attributes on existing Elements. In particular the sample program strips all images from the page and changes text color to blue.


Read elements across all PDF pages

Illustrates how to traverse page display list using ElementReader.


PDF data extraction (images, text, paths)

The sample shows how to use some of more advanced PDFNet features. The sample code illustrates how to extract text, paths, and images. The sample also shows how to do color conversion, image normalization, and how to process changes in the graphics state.


Encrypt and decrypt PDF files

Illustrates encryption support in PDFNet. The sample code reads an encrypted document and sets a new SecurityHandler.


PDF form fill and form data extraction

PDFNet includes full support for FDF (Forms Data Format) and capability to merge/extract forms data (FDF) with/from PDF. The sample illustrates basic FDF merge/extract functionality available in PDFNet.


HTML to PDF converter

Sample code to use PDFTron SDK for directly converting HTML pages to PDF by using 'pdftron.PDF.HTML2PDF'. The HTML2PDF converter supports HTML conversion from a string or URL and offers many options to control page size and formatting.


PDF image extraction

This sample illustrates couple of approaches to PDF image extraction.


PDF imposition

The sample illustrates how multiple pages can be combined/imposed using PDFNet. Page imposition can be used to arrange/order pages prior to printing or to assemble a 'master' page from several 'source' pages. Using PDFNet API it is possible to write applications that can re-order the pages such that they will display in the correct order when the hard copy pages are compiled and folded correctly.


PDF interactive forms (AcroForms)

The sample illustrates some basic PDFNet capabilities related to interactive forms (also known as AcroForms).


PDF image JBIG2 compression

The sample project illustrates how to recompress bitonal (black and white) images in existing PDF documents using JBIG2 compression. The sample is intended to show how to specify hint information for image encoder and is not meant to be a generic PDF optimization tool. PDFNet supports both lossless and lossy JBIG2 compression. To give you a feeling of compression rates possible with PDFNet we re-compressed a document containing 17 scanned pages. The original input document is ~1.4MB and is using standard CCITT Fax compression. Loss-less JBIG2 compression shrunk down the file to 641KB. Lossy JBIG2 compression shrunk down the file to 176KB.


PDF logical structure reader

This sample explores the structure and content of a tagged PDF document and dumps the structure information to the console window.


Multithreaded PDF reading

Illustrates how to use PDFDoc locking mechanisms to access the document concurrently. PDFDoc uses a recursive shared lock model. Multiple threads can read the document at the same time, but only one thread can write to the document. A given thread can acquire as many locks of the same type as it wants, in a recursive fashion.


Use OCR to make searchable PDFs and extract text

This sample shows how to use the PDFTron OCR module on scanned documents in multiple languages. The OCR module can make searchable PDFs and extract scanned text for further indexing.


Create PDFs from MS Office templates

This sample shows how to dynamically generate PDF from an MS Office template file and content supplied via JSON.


Convert MS Office files to PDF

This sample illustrates how to convert MS Office files (Word, Excel, PowerPoint) to PDF.


Compress & optimize PDF files

The sample shows how to use 'pdftron.PDF.Optimizer' to reduce PDF file size by removing redundant information and compressing data streams using the latest in image compression technology. 'pdftron.PDF.Optimizer' is an optional Add-On to PDFNet Core SDK.


PDF page labels

This example illustrates how to work with PDF page labels. PDF page labels can be used to describe a page. This is used to allow for non-sequential page numbering or the addition of arbitrary labels for a page (such as the inclusion of Roman numerals at the beginning of a book).


PDF patterns and shadings

This example illustrates how to create various PDF patterns and shadings.


Convert PDF to PDF/A

This sample illustrates how to validate existing PDF documents for PDF/A compliance as well as to convert generic PDF documents to PDF/A format.

Windows developers can use standard GDI or GDI+ API-s to write on PDFDC and to generate PDF documents based on their existing drawing functions. PDFDC can also be used to implement file conversion from any printable file format to PDF.


Read & write a PDF file from/to memory buffer

The sample illustrates how to read/write a PDF document from/to memory buffer. This is useful for applications that work with dynamic PDFdocuments that don't need to be saved/read from a disk.


Convert PDF to image (JPG, PNG, BMP, TIFF)

This sample illustrates how to use the built-in rasterizer in order to render PDF images on the fly and how to save resulting images in PNG and JPEG format.

This sample demonstrates how to create PDF layers (also known as Optional Content Groups - OCGs). The sample also shows how to extract and render PDF layers.


PDF packages (Portfolios)

This sample illustrates how to create, extract, and manipulate PDF Packages (also known as PDF Portfolios).


Merge, copy, delete and rearrange PDF pages

The sample illustrates how to copy pages from one document to another, how to delete, and rearrange pages and how to use ImportPages() method for very efficient copy and merge operations.


Print PDF a file

This sample illustrates how to print a PDF document using the currently selected default printer. It is possible to use PDFNet printing functionality in both client and server applications without dependence on any third party components.


PDF redaction

The sample shows how to use 'pdftron.PDF.Redactor' to remove potentially sensitive content within PDF documents. PDFTron Redactor makes sure that if a portion of an image, text, or vector graphics is contained in a redaction region, that portion is destroyed and is not simply hidden with clipping or image masks.


PDF Viewer control (Advanced)

This sample shows how to customize the viewer control by implementing a number of custom tools (such as freehand tool, link creation tool, rectangular zoom etc) and custom GUI elements (such as custom navigation and printing). For a more introductory example of how to use PDFViewCtrl, please see PDFViewSimple sample project.
