LINQ Reporting Engine - Insert image document ODT

Inside an odt document I have a frame with a inside grid inside in a cell I have inserted another frame with the tag <<image [Util.qr(qrcode)]>>. The image is not inserted and my Util.qr function is not invoked. Why ? Thanks.

@samuele.lucarini

Could you please share your template, data, and code, so we could check the scenario on our end?

This is my code for insert generated QRCode Image :

 public class Util {
 
   private Util() {
     throw new IllegalStateException("Utility class");
   }
 
   private static final int BARCODE_RESOLUTION = 300;
 
  
 
   // QR CODE
 
   /** Generates a QR Code from a value. */
   public static byte[] qr(String value) throws IOException {
     return qr(value, false);
   }
 
   public static byte[] qr(String value, boolean caption) throws IOException {
     return qr(value, null, null, caption);
   }
 
   /**
    * Generates a QR Code from a value.
    *
    * @param version {@link QRVersion}
    */
   public static byte[] qr(String value, String version) throws IOException {
     return qr(value, version, false);
   }
 
   /**

Attach data.zip with (dati.xml and template.odt)data.zip (8.6 KB)

Microsoft Word is unable to load a textbox for your ODT template. I believe, there is a similar issue with Aspose.Words as it mimics Microsoft Word. WORDSNET-24776 is logged for the sake of further investigation. You will be notified through the forum thread, once we have any update on it.

is there another way to create a report with 3 columns and n rows without using the external frame present in the template?

Example
Item 1 Item 2 Item 3
Item 4 Item 5 Item 6
Item 7

Please check Template.zip (4.6 KB). It shows a basic idea. For more information, please check the following articles:
