Ho to define size of barcode or QR Code in report

[jlabuelo]

Hello all

We are using Jasper Report Studio v6.3.1. We have built a simple report with a jrxml file that produces an A7 document with two pages, the first of all with a BarCode and the second one with a QR code.

The report only receives a Parameter called "Code" and must produce the barcode and the QRcode with the value of this parameter. The issue we are having is that we are able to get the report generated, but the size of the barcode image and qr image are two small and no matter which values we assign to the with and height of the elements, size does not change.

Dont know if it is possible to attach the jrxml as example but the definition is this one

Is there any way we can adjust the size of the image of the barcode and qrcode??

Thanks a lot

Hi Jlabuelo,

I think the Bar code size and QR code are good. They are in a same size as you are expecting. 

I see the page size of the reports you defined is small[your page width = 297] so you will see the complete report only of that width.

If you are looking for normal A4 size report please increase the width of the report[width:595  height;842].

 

Thanks!
