PDF reproducing the bug - barcodes not rendered

Please see bottom of page 2 for the attached document. Krusader's PDF viewer (for example) shows 3 barcodes. Draw only shows the numbers, but not the bar codes.

No, the pdfium base "Insert as image" renders the barcodes correctly to document canvas (must first split the 2nd page from the PDF, i.e. PDFtk or similar). 

Though, on break of the image on canvas it does loose any barcode graphic sense.

As LibreOffice is *not* a PDF editor, lack of import code to render a "barcode" formatted drawing object seems pretty trivial. As an image it is fully supported.

IMHO this goes => NAB

But then modifying the pdfio to use the ZXing libs to render various "QR" and "barcode" 3D/2D codes into Draw shape objects on canvas seems a valid enhancement request.

The sample file uses the EX_CFF_3OF9 font. If not installed, it is not interpreted properly. For me is NOTABUG. It is a missing font issue.

I formated the three frames with an alternate 3of9 code font, and could see the barcode (without the bottom numbers, that are not included in this font).

Sorry I'm not technical enough to make sense of this, but on the same machine I see the barcode in the PDF just fine with the Krusader viewer, so the font must be installed.

I'd expect specialized PDF editing like Draw to be more able than Krusader to display *and edit* PDFs.

But if for some reason barcodes can't be rendered due to a missing form, shouldn't Draw inform the user about that?

What I needed Draw for was to sign that PDF, so I don't care if I don't see the barcode, as long as it's saved correctly. But right now it looks "corrupted", so I didn't want to risk corrupting the file, and had to resort to a non-open source PDF signing solution, which now has a copy of my signature :-/
