Reduce size of content in template header

Content

Hello,

I have a repeated header in my template and the barcode is huge which prevents me from making the display I want  :

The code behind this barcode is <?format-barcode:SHIPMENT_XID;'code128a'?> and the size of the "code 128" font is 24 and it appears quite small on my report so I would like to make it even bigger in my report and be able to reduce the size in the template.

N.B : this is a problem since in headers it isn't possible to make fields with a short display name, so is there a workaround ?

Thanks in advance.
