Android Question PDF Document Looks Different on two different devices.

[Nokia]

I have an odd problem,

I have two devices (both Samsung tablets)

Device 1:
Samsung Galaxy Tab A
Model: SM-T550
Android version: 7.1.1

Device 2:
Samsung Galaxy Tab A
Model: SM-T580
Android Version: 8.1.0

I designed the software on device 1 and run great with no issues on device 2 except when producing a pdf file. I am using the PDFDocument library from this site. when I produce pdf file on device 1, it looks how I designed it (picture attached device-1). But when I produce the pdf on device 2 (picture attached device-2), the document size is correct, but all my text looks zoomed and hangs of the document page.

I have attached sample images, any idea on what's going on here?

Looks like you aren't dividing the font size with the device scale: https://www.b4x.com/android/forum/threads/printing-and-pdf-creation.76712/#content

Thanks Erel, worked...

Was wondering if the PDFDocument library would work for B4J?
I have the same software on B4J as a desktop version and would love to produce the same pdf files with same code...

It will not work as it is based on Android specific APIs.

Last question, do you have anything similar for B4J?

And again.. Thanks..

Did you see - it shows how to create PDF docs in B4J?

do you have to have word installed on the computer to do this?

wd.OpenWord and wd.PowerShellConvertToPdf are Windows only methods and depend on MS Word being installed. All other methods are based on jPOI (Apache POI) and do not depend on anything else.

thanks for the update. I will try this out for my windows app..

Yes you do.

But maybe this (for basic PDFs) will work for you. It says that it will work in B4J as well as B4A, but I haven't tried it.
