ByteArray To image

I’m working with Aspose.Words for .NET (v24.10) and would like some guidance on inserting a signature image from byte array coming in payload into a Word template using the LINQ Reporting Engine.

My Use Case:

  • I receive a byte array (or base64 string) representing a signature image as part of my payload.
  • I’m generating the final output using LINQ-based templates, which are converted into PDF using Aspose.
  • I want to map this signature image to a specific placeholder within my Word template.

To insert a signature image from a byte array into a Word template using Aspose.Words for .NET and the LINQ Reporting Engine, you can follow these steps:

  1. Convert the Byte Array to an Image: You can directly use the byte array to insert the image into the document. The DocumentBuilder class provides methods to insert images from byte arrays.

  2. Insert the Image at the Placeholder: You will need to identify the placeholder in your Word template where the signature image should be inserted. This can be done using LINQ Reporting Engine syntax.

Here’s a sample code snippet demonstrating how to achieve this:

using Aspose.Words;
using Aspose.Words.Drawing;
using System.IO;

// Assuming you have a byte array for the signature image
byte[] signatureImageBytes = /* your byte array here */;

// Load your Word document
Document doc = new Document("path/to/your/template.docx");
DocumentBuilder builder = new DocumentBuilder(doc);

// Move to the placeholder where you want to insert the image
builder.MoveToBookmark("SignaturePlaceholder"); // Replace with your actual bookmark name

// Insert the image from the byte array
builder.InsertImage(signatureImageBytes);

// Save the document
doc.Save("path/to/your/output.docx");

Explanation:

  • DocumentBuilder: This class is used to manipulate the document. You can navigate to specific locations in the document using bookmarks or other methods.
  • InsertImage: This method allows you to insert an image directly from a byte array. You can also specify dimensions if needed.

Note:

Make sure that the byte array you are using is a valid image format supported by Aspose.Words (like PNG, JPEG, etc.).

This approach will allow you to dynamically insert a signature image into your Word document based on the byte array received in your payload.

If you have any further questions or need additional assistance, feel free to ask!

@lalit2207 Please see our documentation to learn how to insert image:
https://docs.aspose.com/words/net/inserting-images-dynamically/

Please see the following simple code example:

JsonDataSource ds = new JsonDataSource(@"C:\Temp\data.json");

Document doc = new Document(@"C:\Temp\in.docx");

ReportingEngine engine = new ReportingEngine();
engine.BuildReport(doc, ds);

doc.Save(@"C:\Temp\out.docx");
