We got our answer from SAP (since their version is a bit different). It
cannot be done. However, they suggested creating the barcode via another
3rd party solution and convert that to an image and import that image
into the label. We used LiveCycle Designer to do that and created a
larger barcode that would work.
I use Adobe LiveCycle Designer from SAP and I'm trying to create a label
that requires a Data Matrix 2D barcode that is 5/8" (.625in) square. The
smallest that I've been able to create is .8317in. Anything smaller and
I get a box with a lightning bolt and the PDF View just shows a grey
box. Am I doing something wrong? Is there a physical size limitation? I
am using ES4 version 11.01.20140218.1.907162 and this is part of SAP.
