Text Ean-13 barcode error

I'm trying to print a label with an Ean-13 barcode. The barcode must have dimensions of about 27x10mm but by setting these dimensions the text is not resized correctly and is poorly formatted.

I also tried to hide the text by setting TextLocation to None but the text is not hidden but moved above the barcode.

The code I'm using is this:

            //Barcode
            PdfEan13Barcode ean13 = new PdfEan13Barcode();
            ean13.Size = new SizeF(MmToPoint(27), MmToPoint(10));
            ean13.Location = new PointF(MmToPoint(2), MmToPoint(20));
            ean13.Text = "8022983191959";
            ean13.TextDisplayLocation = TextLocation.None;
            ean13.Draw(page);

            ean13 = new PdfEan13Barcode();
            ean13.Size = new SizeF(MmToPoint(27), MmToPoint(10));
            ean13.Location = new PointF(MmToPoint(2), MmToPoint(35));
            ean13.Text = "8022983191959";
            ean13.TextDisplayLocation = TextLocation.Bottom;
            ean13.Draw(page);

Attached is the generated PDF.

Hi CSharpino, 
 
Thank you for contacting Syncfusion support. 
 
The barcode must have dimensions of about 27x10mm but by setting these dimensions the text is not resized correctly and is poorly formatted. 
We have tried the EAN 13 Barcode creation with provided code snippet on our end, but it resize properly. And the provided code has same size for both the barcodes. We have also checked with different size, its resize the barcode properly. Kindly provide more details such as complete code snippet or sample, product version to check the issue in our end. So, that it will be helpful for us to analyze and assist you further on this. 
 
However, can you please confirm whether you are reporting this as a format issue like below (text are rendered on the barcode), 
 
 
I also tried to hide the text by setting TextLocation to None but the text is not hidden but moved above the barcode. 
We were able to reproduce the text location hidden issue with provided details on our end. Currently, we are validating on this and we will update the further details on April 12th 2021.   
 
Regards,

Yes, the problem with resizing is that the text under the barcode is not formatted correctly.
The text should decrease its size proportionally to the size of the barcode or even better you should allow the user to change the font size.
