GroupDocs.Signature for .NET 22.4 Release Notes

Major Features

This release contains an important features for ordering the electronic signatures on document pages. The new options Order was implemented for page-oriented signature types like Text, Image, Barcode, QRCode and Stamps and supported for most document types such as Spreadsheets, Word Processing and Images. Having this feature will allow the front-end applications to adjust signature ordering on the page and move them from back to front. Also this release contains significant optimization for document type detections and implementation of sull svg-image file format support. Below the list of most notable changes in release of GroupDocs.Signature for .NET 21.4:

  • Implemented ability to specify the order of signature for Spreadsheet, Word process and Image documents.
  • Provided full SVG file type support for image documents and most signature types.
  • Involved a significant optimization of file detection algorithm.
  • Implement adjustment on image preview signature for front-end applications.
  • Fixed a few internal issues.

Public Developer Guide examples changes

The following topics from Developer Guide were added

Sign document with ordering the signatures

Public API and Backward Incompatible Changes

Public class SignOptions was updated with ZOrder property

Property [ZOrder] expects integer values to put the signatures on document page in proper order.

The following example demonstrates how to setup special ordering of the signatures on the document page.

Generate signature preview

public static void Run()
    using (Signature signature = new Signature("sample.png"))
        // create several signatures that intersect
        // # 1 create barcode option with predefined barcode text
        // this options will be on top
        BarcodeSignOptions options1 = new BarcodeSignOptions("12345678")
            // setup Barcode encoding type
            EncodeType = BarcodeTypes.Code128,
            // set signature position
            Left = 100,
            Top = 100,
            Width = 100,
            Height = 100,
            ZOrder = 2,
        // # 2 create barcode option with predefined barcode text
        // this options will be bottom
        QrCodeSignOptions options2 = new QrCodeSignOptions("12345678")
            // setup Barcode encoding type
            EncodeType = QrCodeTypes.QR,
            // set signature position
            Left = 150,
            Top = 150,
            ZOrder = 1
        // sign document to file
        List<SignOptions> options = new List<SignOptions>() { options1, options2 };
        SignResult signResult = signature.Sign(outputFilePath, options);
        Console.WriteLine($"\nSource document signed successfully with {signResult.Succeeded.Count} signature(s).\nFile saved at {outputFilePath}.");
