The PDF Library now supports intelligent font subset embedding during PDF to PDF/A conversion, including only essential characters.

Benefits

• Significantly reduced file sizes for efficient storage.

Advanced AES GCM encryption for PDFs

With the AES GCM encryption, users can encrypt or decrypt PDF documents using a secure and modern cryptographic standard. This enhances data protection by offering both confidentiality and integrity in professional workflows.

Grouped form fields

Complex forms become manageable with grouped form fields in a PDF for improved organization and easier data handling. This enhancement simplifies:

• Complex form development with logical field grouping.
• Batch data processing across related fields.
• Consistent styling application.
• Coordinated validation logic.

Enhanced redaction annotations

Word Framework

JavaScript Word Processor

Ribbon

The Document Editor now features a complete Microsoft Word-like Ribbon UI with:

• Contextual tabs that appear based on user actions.
• Intuitive tool organization for faster editing.

• Streamlined user experience with familiar navigation.

Screen reader

The Document Editor now provides complete accessibility information. When enabled, it provides the necessary information so that screen reader tools can read and interpret the content.

Enable/disable layout

The new enableLayout API lets users skip the layout and rendering process when loading or editing documents programmatically, improving performance. By default, layout and rendering run as usual, but can be disabled to speed up bulk changes programmatically in the Document Editor.

Editing enhancements

The following enhancements allow users to automate the required behaviors of editing the Word document content easily.

• API to retrieve fields that are present within the selected area of a document.
• API to remove the selected editing region from a Word document.
• API to get and set scroll positions facilitates synchronizing the scroll positions of two Word Processor components. Using this feature, users can easily configure side-by-side viewing of two Word documents.
• API to delete the selected paragraph from a Word document. This also helps customize and automate document editing.
• Group undo and redo enables seamless tracking of consecutive edits, like Microsoft Word. This reduces the undo operation count on the typed text and does not undo character by character.

Group shape

This feature ensures that the group shape in Word documents is preserved, maintaining its integrity when a document is opened and saved using the Word Processor component.

.NET Word Library

Editable regions in protected documents

The .NET Word Library now supports editable regions within protected documents, enabling controlled editing of specific sections while maintaining overall document integrity.

This is useful for:

• Contract templates with fillable sections.
• Forms requiring partial user input.
• Protected templates with designated update areas.
• Collaborative documents with role-based editing rights.

Multilingual list numbering

International document creation becomes seamless with a comprehensive multilingual list numbering. Create different list number formats such as Arabic, Hebrew, Chinese, and Thai. Ensures numbering styles remain accurate in multilingual documents like:

• Global business reports with multiple languages.
• International contracts requiring native numbering.
• Educational materials for diverse audiences.

Enhanced shape and picture processing

The following enhancements are now added for shapes and pictures in Word-to-PDF and image conversion.

Shape format improvements: 

• Gradient fills are preserved in the Word-to-PDF conversion.
• Transparent effects are maintained across formats.
• Pattern fills are rendered accurately in output documents.

Picture recoloring support:

• Sepia tone adjustments are maintained in the final output.
• Color tone modifications are accurately rendered.

These enhancements ensure brand consistency and visual appeal in marketing materials, reports, and presentation documents.

Drawing canvas preservation

Complex diagrams and flowcharts maintain their structure with drawing canvas preservation. Drawing canvases and their contents remain intact during Word-to-PDF and image conversions, which is useful for maintaining the layout in grouped shapes, flowcharts, or diagrams used in reports, manuals, and presentations.

Excel Framework

.NET Excel Library

Auto fill and fill series

The .NET Excel Library supports auto fill and fill series features, allowing users to programmatically fill a range of cells based on patterns, sequences, or trends, eliminating manual data entry.
