DrawPdf not honouring width and height input #250

Open Joshmul1 opened 2 weeks ago

Joshmul1 commented 2 weeks ago

When using the Viewer package the default 4x6 label size is not honoured when the PDF is created, instead it seems to be a constant 11.11 x 13.33 inches (281.94 x 338.58 mm) when inspected using adobe.

This can be replicated using the online viewer at https://binarykits-zpl-viewer.azurewebsites.net, Using https://labelary.com/ with the same ZPL and settings does honour the size requirement.

Any help into figuring out why its behaving this way would be great, I am going to try debug and fix it myself but I am unfamiliar with this code base.

Thanks

Okay I have an update, I think I found the issue and will create a PR for it just now.

The BeginPage method requires the passed value to be inches * 72, where 72 is the PdfDpi. This value is currently being passed in millimetres. The PDF is also not being scaled correctly, but as far as I can tell this is now all fixed with my change.
