Hi,
I’m using Aspose.Words to insert tags in a .docx file, which I then pass to the engine along with JSON data for document generation. Now, I want to add QR code support so that by simply placing a tag in the .docx file, the generated document will display a QR code at that position. How can I implement this?
Thank you in advance.
To add QR code support in your Word template using Aspose.Words, you can utilize a custom barcode generator. This allows you to insert a tag in your .docx file that will be replaced with a QR code during document generation.
Cause: You need to generate QR codes dynamically within your Word documents.
Solution: Follow these steps to implement QR code support:
Create a Custom Barcode Generator: Implement the IBarcodeGenerator interface to define how the QR code will be generated.
Set the Barcode Generator: Use the FieldOptions class to set your custom barcode generator.
Insert a QR Code Field: In your Word template, insert a field that will be replaced with the QR code. You can use a specific tag format to identify where the QR code should be placed.
Generate the QR Code: When processing the document, generate the QR code based on the data you want to encode.
Here’s a minimal code example to illustrate this:
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// Set a custom barcode generator
doc.getFieldOptions().setBarcodeGenerator(new CustomBarcodeGenerator());
// Insert a QR code field in the document
FieldBarcode fieldBarcode = (FieldBarcode) builder.insertField(FieldType.FIELD_MERGE_BARCODE, true);
fieldBarcode.setBarcodeType(EncodeTypes.QR);
fieldBarcode.setBarcodeValue("Your data here");
// Save the document
doc.save("output.docx");
In this example, replace "Your data here" with the actual data you want to encode in the QR code. The CustomBarcodeGenerator should handle the specifics of generating the QR code image.
Next Steps: Implement the CustomBarcodeGenerator class to define how the QR code images are generated. Test the document generation to ensure the QR codes are correctly inserted.
If you have any further questions or need assistance with specific parts of the implementation, feel free to ask!
Can you please provide me actual input, output and data ?
@jilp You can find full code example here:
https://docs.aspose.com/words/net/how-to-generate-a-custom-barcode-image-for-displaybarcode-field/
Also you can fond example in our github:
https://github.com/aspose-words/Aspose.Words-for-.NET/blob/master/Examples/ApiExamples/ApiExamples/CustomBarcodeGenerator.cs
I understood the logic but still my question is how should i write tag (<<[]>>) in word template ?
@jilp Do you use LINQ Reporting Syntax? If so, you can put the syntax into DISPLAYBARCODE field. For example see the following documents and code:
Document doc = new Document(@"C:\Temp\in.docx");
ReportingEngine engine = new ReportingEngine();
engine.BuildReport(doc, "1234567890", "code");
doc.Save(@"C:\Temp\out.docx");
