Sumit Jha commented on PDFBOX-3216:
-----------------------------------
One other approach I tried without converting to image has below sample code.
But with this approach I faced these problems as I told that source PDFs are
different formats:
1. Converts some PDF to Bad PDF (error message while opening PDF using acrobat
reader)
2. Converts some PDF to Blank PDF

> Affects Versions: 1.8.10
> Environment: Windows 7, JAVA 1.7

> We are seeing that there are few problems while converting few PDFs:
> 1. In some source PDFs bullet point listed is changed to some different icon
> in converted PDF.
> 2. In some PDFs when there is a bullet point in the source document the text
> on the line following the bullet point is destroyed/missing characters.
> We’ve read some posts that we should try using the PDFBOX version 2.1.10, but
> that is not an approved version at our company and it is not released too.
> I should also note that the source PDF documents we are trying to add the Bar
> Codes to are quite varied- they can come in any size, using any font, with
> images, and be oriented portrait or landscape. The goal is to get these
> printed on 8.5 by 11 inch paper with a barcode on them at top.
> Do you have any suggestions on how to proceed?
