The geometry type “MultiLineString” represents an array of two or more geographic points. The geometry type “MultiPoint” represents an array of points that renders circle markers. The geometry type “GeometryCollection” is a special type that contains various geometries as members.

PDF Library

PDF/A-4 conformance

PDF/A-4 is the latest edition of the PDF/A conformance series based on ISO 32000-2 (PDF 2.0). This new format allows non-static content in PDF documents in the form of JavaScript, so the logic of an interactive form can be stored and archived. Additionally, it simplifies the handling of digital signatures.

PDF/A-4 has the following conformance levels:

  • PDF/A-4e: This conformance level is intended for technical documents. It supports 3D models, rich media, 3D annotations, and embedded files to create a PDF/A version compatible with engineering workflows.
  • PDF/A-4f: This conformance level allows embedding files in any other format.

Now the Syncfusion .NET PDF Library supports the creation of PDF/A-4 conformance documents and the conversion of existing PDF documents to PDF/A-4 conformance.

RichMedia annotation

RichMedia annotations can be used to embed videos and sound files in PDF documents. The user can play the media content as part of the page content by just clicking on the video or audio. This annotation is newly introduced in PDF 2.0 to replace sound and movie annotations, which are deprecated in PDF 2.0.

Watermark annotation

The .NET PDF Library now supports the watermark annotation, which is used to show text, images, and shapes as watermark content in page graphics with a fixed size and position. It supports the following features:

  • Text, images, and graphical shapes.
  • Rotation to 0, 90, 180, and 270 degree angles.
  • Customization as a print-only watermark (annotation disappears in view mode).
  • Existing watermark annotations can be edited or removed.
