            Bug ID: 155889
           Summary: the exported *.png image can't be seen normally as the
                    initial image

           Version: 7.0.4.2 release
          Hardware: x86 (IA32)
                OS: Linux (All)

Created attachment 187955
  --> https://bugs.documentfoundation.org/attachment.cgi?id=187955&action=edit
It's a *.png image of the site mentioned in bug description

Simple explanation:
==================

  1. Right-click attachment and select "Open with -> LibreOffice Draw"
  2. Export to *.png
       and in PNG Options set "Resolution:" to 300dpi (pixels/inch)

  Conclusion:
    Bug: I can't see the exported *.png image as I can see the *.png image in 
           attachment that was opened with LibreOffice Draw 
          (particularly I can't see/read the text in the exported image as I
can 
           see/read the text in the image before opening it with LibreOffice 
           Draw).


  Note:

    To be honest I don't even know exactly if this is a bug or if it is simply 
       something that isn't behaving as expected.


  Explanation of what I was expecting:
  ===================================

    Before I open the image with LibreOffice Draw, if I open the *.png image in 
      attachment in Firefox and then click in the image to zoom it, I can see 
      the image normally including the text in it.

    If I try to do exactly the same with the exported *.png image I cannot see 
       the image normally anymore I can't even read the text in it, I mean if I 
       open the exported *.png image in Firefox and then click in the image to 
       zoom it, I cannot see the image normally as before I can't even read the 
       text in it.

  And now you ask, why are you exporting to *.png an image that is already a
  ==========================================================================
       *.png image ?
       ===========

  Answer: Well, what I was trying initially was something similar but slightly 
  ======      different, initially I was trying to export the same *.png image 
              in attachment but with a "Text-box" inserted containing the text: 
    "https://www.intel.com/content/www/us/en/processors/processor-numbers.html"; 

     and I tried to see in Firefox the exported *.png image of that and I 
     couldn't see it too as before not even read the text in it, so I've
decided 
     to do even simpler which was what I described you in this bug report which 
     is simply open a *.png image with Libreoffice Draw and then immediately 
     export it as *.png, setting "Resolution:" to 300dpi (pixels/inch) and I 
     couldn't see it either not even read the text in it and 
     that's why I've decided to report this behaviour as a bug.

  Note2: The *.png image in attachment is basically the site above mentioned I 
             screenshot with Firefox right-click "Take Screenshot" option.
