機能

Blazor Server Support

  • You can now use the DevExpress Office File API components within server-side Blazor applications. With the Office File API, you can execute multiple document-related actions (create, load, edit, and print rich-text documents, spreadsheets, and PDF files).

Digital Signatures (CTP)

  • This new API allows you to:
    • digitally sign Office files (Word documents, Excel spreadsheets, and PowerPoint presentations) with X.509 certificates.
    • configure signature options (select a signing certificate, specify a digest algorithm, define clients used to obtain timestamps and certificate revocation status).
    • validate digital signatures in existing documents to ensure the authenticity and integrity of document content.

PDF Document API

  • Sticky Notes and Comments
    • You can now access, edit, comment, and delete PDF sticky notes.
  • PAdES - BES (LT and LTA levels) Signatures
    • You can now sign documents with PAdES signatures using B-LT or B-LTA signature levels.
  • Cross-Platform Rendering
    • The PDF Document API allows you to use the Skia Graphics Engine to render page content across multiple OS platforms (Microsoft Windows, Linux, or Microsoft Azure).
  • Page Manipulation Enhancements
    • You can now execute the following actions against PDF page content:
      • Scale content.
      • Specify content offset.
      • Rotate content.
      • Resize the page (while maintaining content aspect ratio).
  • Draw Page Content
    • The PdfGraphics.DrawPageContent method allows you to insert page content to a different page. You can merge the contents of two separate pages into one.

Spreadsheet Document API

  • Microsoft Excel 2016 Charts (CTP)
    • The Spreadsheet Document API now supports the following Microsoft Excel 2016 chart types:
      • Box and Whisker
      • Funnel
      • Histogram
      • Sunburst
      • Treemap
      • Waterfall
      • Pareto
    • Use the Spreadsheet API to create, load, edit, print, and export (to PDF) Microsoft Excel 2016 charts *.
      * You cannot print and export to PDF Treemap and Sunburst charts.
  • Fixed DPI for Document Layout Calculation
    • v20.2 includes a new option - Workbook.Options.Layout.Dpi. This option specifies the resolution (DPI) used for document layout generation. You can now generate identical documents and print-outs on machines with different screen DPIs.

Word Processing Document API

  • Break Table Rows Across Pages
    • Enable the new TableRow.BreakAcrossPages option to break table rows across pages.
  • OLE Objects
    • The Word Processing Document API and Rich Text Editor for WinForms and WPF support OLE objects. The new API allows you to access and edit OLE objects in code. Documents with OLE objects can be printed and exported to PDF.
  • 'Keep with Next' and 'Widow/Orphan Control' in Tables
    • The Word Processing Document API and WinForms/WPF Rich Text Editors now apply the following options when they display, print, and export (to PDF) documents with table paragraphs:
    • Keep with Next
    • Widow/Orphan Control
  • Load Document Properties
    • The Word Processing Document API allows you to load document metadata (or document properties) without loading the document itself.
  • 'Filling in Forms' Protection
    • You can now set up "Filling in Forms" protection in code. To protect a form, set the Document.ProtectionType property to DocumentProtectionType.FillInForms.
  • New Formats
    • The Word Processing Document API and WinForms/WPF Rich Text Edit controls now support the following file formats:
      • DOCM (Microsoft Office Open XML Macro-Enabled Document format)
      • DOT (Microsoft Word 97-2003 Template format)
      • DOTM (Microsoft Office Open XML Macro-Enabled Template format)
      • DOTX (Microsoft Office Open XML Template format)
      • FlatOpc XML (Microsoft Word XML Document stored in a flat XML file instead of a ZIP package).
  • Document Rendering Enhancements
    • Table width and justified paragraph alignment are now calculated more accurately and better mirror Microsoft Word 2013 and later.
  • Asynchronous Load and Save
    • The new API allows you to load, save, and export documents to PDF and HTML asynchronously. Use the following new methods (RichEditDocumentExtensions class):
      • LoadDocumentAsync
      • LoadDocumentTemplateAsync
      • SaveDocumentAsync
      • ExportToPdfAsync
      • These methods can accept a CancellationToken as a parameter. This allows you to terminate the operation when appropriate.
Now supports Excel 2016 chart types.
