Description oli4stuker 2018-03-07 05:51:18 UTC
Description:
When embedding a pdf as an image, the image is printed blank when the document is exported as pdf.

Steps to Reproduce:
1. New Writer document
2. Insert > Image... > choose any pdf that wasn't created with LO and open *
3. Add some text
4. Export as PDF **

* doesn't matter if embedded or linked
** doesn't matter if using the toolbar button "Export as PDF" or File > Export as PDF...

Actual Results:  
Text is visible, but image is not in exported pdf file

Expected Results:
Image should be visible in exported pdf file too


Reproducible: Always


User Profile Reset: No



Additional Info:
- It seems to work with pdf files that were created with LO, but not with others e.g. pdf files created by InkScape. If desired, I can provide pdf files.

- It worked as expected in 5.4.3.2

I can reproduce with an inscape produced pdf in 5.4.3

Seems to effect Write and Impress equally.
(Though Bug 104998 makes 5.4 useless for working with embeded pdf files).

I can't reproduces in:
Version: 5.4.5.1

Could you upload the pdf file that triggers this for you.

Can't reproduce with attachment 140426 [details] and

Version: 6.1.0.0.alpha0+ (x64)

So if you, Telesto are able to reproduce it with the master, it might depends on the setings of the PDF-Export?
Comment 5 Telesto 2018-03-08 10:04:51 UTC
A, I found an explanation for the difference. The PDF contains the image, but not every PDF reader can handle it.

Windows Build in PDF reader -> No image
PDF XChange Viewer -> No image
Comment 6 Dieter 2018-03-08 10:37:52 UTC
I use Adobe Acrobat Reader DC

Miklos: is this notourbug?
Comment 9 Miklos Vajna 2018-03-09 09:27:39 UTC
https://www.pdf-online.com/osa/validate.aspx output for our pdf output:

> File	saved.pdf
> Compliance	pdf1.4
> Result	Document does not conform to PDF/A.
> Details	
> 
> Validating file "saved.pdf" for conformance level pdf1.4
> 
> The name a0 of a graphics state dictionary resource is unknown.
> 
> The document does not conform to the requested standard.
> 
> The document doesn't conform to the PDF reference (missing required entries, wrong value types, etc.).
> 
> The document does not conform to the PDF 1.4 standard.
> 
> Done.

So it's a bug.

This can be tested from 5.3 when PDF image could be inserted. And I could open an image from 5.3. with PDF-XChange Viewer. So I'll ask bibisectRequest.
As noted, from 5.4 probably all up to 7.0+ inserted PDF images is not seen, except with Adobe.
Comment 12 Buovjaga 2020-03-23 16:57:18 UTC
Miklos: I bibisected using the PDF Tools Online Validator (repo win32-5.4). I was pointed to a range of commits https://gerrit.libreoffice.org/plugins/gitiles/core/+log/ff8b873936aa72b17309da4bfc2775573a5b1f55..169bd7718264b0e312052757f9bbd2321e1399c2
