• Unused object removal. This option can help you create smaller files
• Serialize a document to memory, stream, or a file on disk

Efficiency

PDFNet was designed from ground up with high throughput and current applications in mind.

• For speedy document reading, PDFNet uses incremental object loading and caching mechanisms. Caching is used at different levels: from Cos based object caching to more sophisticated color-space, font and glyph caching.
• Incremental save for fast serialization and document versioning

Convert Add-on is a universal document converter allowing developers to convert from any printable format to PDF, XPS, EMF, or SVG using a very simple API. To provide the highest quality output PDFNet implements a number of direct converters that preserve text, vector graphics, hyperlinks, colors and fonts. PDFNet also seamlessly integrates with Microsoft Office (if available) and can maintain metadata, text, links when converting from Word, Excel, Outlook, or PowerPoint to PDF or XPS. Feature highlights include:

• Direct conversion from PDF to XPS and XPS to PDF. The high-quality conversion maintains the original document quality and preserves vector graphics, text, hyperlinks, colors and fonts.
• Direct conversion from PDF to EMF/WMF and from EMF to PDF/XPS.
• Direct conversion from PNG, JPEG, TIFF, GIF, BMP, HDPhoto to PDF/XPS.
• Direct conversion from PDF to SVG.
• Direct conversion from HTML to PDF (or XPS/SVG etc) using 'pdftron.PDF.HTML2PDF'. HTML2PDF converter supports HTML conversion from a string or URL and offers many options to control page size and formating.
• Dynamic PDF generation from XAML and WPF reflow-able content (FlowDocument, Canvas, RichTextBox, etc).
• Support for high quality conversion from Word, Excel, Outlook, or PowerPoint via Office interop.
• Conversion from any printable document to PDF, XPS, or SVG using universal document conversion based on the XPS print path.
• Easy to use API without the need to separately distribute, install, or register any additional files.

PDF/A Add-on allows developers to convert generic PDF documents to PDF/A (ISO 19005-1).

• Checks if a PDF file is compliant with PDF/A (ISO 19005-1) specification.
• Converts any PDF to a PDF/A compliant document.
• Supports both PDF/A-1a and PDF/A-1b.
• Produces a detailed report of compliance violations and associated PDF objects.
• Keeps the required changes to a minimum, preserving the consistency of the original.
• Tracks all changes to allow for automatic assessment of data loss.
• Allows user to customize compliance checks or omit specific changes during the conversion process.
• Supports user-defined color profiles.
• Offers automatic font substitution, embedding, and subsetting options.

PDF Optimizer Add-on optimizes PDF documents by reducing the file size, removing redundant information, and compressing data streams using the latest in image compression technology. PDF Optimizer can compress and shrink PDF file size with the following operations:

• Remove duplicated fonts, images, ICC profiles, and any other data stream.
• Optionally convert high-quality or print-ready PDF files to small, efficient and web-ready PDF.
• Optionally down-sample large images to a given resolution.
• Optionally compress or recompress PDF images using JBIG2 and JPEG2000 compression formats.
• Compress uncompressed streams and remove unused PDF objects.

PDF Redaction Add-on offers options to remove (not just covering or obscuring) content within a region of PDF. With printed pages, redaction involves blacking-out or cutting-out areas of the printed page. With electronic documents that use formats such as PDF, redaction typically involves removing sensitive content within documents for safe distribution to courts, patent and government institutions, the media, customers, vendors or any other audience with restricted access to the content. The redaction process in PDFNet consists of two steps:

1. Content identification: A user applies redact annotations that specify the pieces or regions of content that should be removed. The content for redaction can be identified either interactively (e.g. using ‘pdftron.PDF.PDFViewCtrl’ as shown in PDFView sample) or programmatically (e.g. using ‘pdftron.PDF.TextSearch’ or ‘pdftron.PDF.TextExtractor’). Up until the next step is performed, the user can see, move and redefine these annotations.
2. Content removal: Using ‘pdftron.PDF.Redactor.Redact()’ the user instructs PDFNet to apply the redact regions, after which the content in the area specified by the redact annotations is removed. The redaction function includes number of options to control the style of the redaction overlay (including color, text, font, border, transparency, etc.).

PDFTron Redactor makes sure that if a portion of an image, text, or vector graphics is contained in a redaction region, that portion of the image or path data is destroyed and is not hidden with clipping or image masks. PDFNet API can also be used to review and remove metadata and other content that can exist in a PDF document, including XML Forms Architecture (XFA) content and Extensible Metadata Platform (XMP) content.
