#701: Blank output with OSGeo4W's GDAL 3.3.1 build
---------------------------+-----------------------------------------
Reporter:  philiusmaximus  |      Owner:  osgeo4w-dev@…
    Type:  defect          |     Status:  new
Priority:  major           |  Component:  Package
 Version:                  |   Keywords:  GDAL pdf Georeferencer QGIS
---------------------------+-----------------------------------------
 I'm working int he latest version of QGIS and I need to georeference a
 pdf.
 Georeferencer opens all .pdf files but some are not visible; they appear
 white with no image detail.

 This does not occur on all .pdf files and I have attached one example
 where it does not work for me.

     I have tried different QGIS profiles and created a new one (this does
 not fix the bug)
     I have tried printing the document to pdf and opening the print (that
 does not fix the bug)
     The .pdf file is not layered, has no markups, special features, that I
 can see (using Foxit)
     This was going wrong for me on 3.16.7 so I updated to 3.16.11 (this
 did not fix the bug)
     I have uninstalled all my third party plugins and tried (this does not
 fix the bug)
     Same file opens successfully in 3.10.4 (randomly chose an older
 version where I knew it worked)

 I can open the pdf successfully on an older version of QGIS with an older
 version of GDAl and that works fine. Example screenshots of that attached.

 Up until now I have been able to take screenshots of the pdf files that
 have this error and geocode those instead, but I will be trying to geocode
 some large plans soon and I don't think screenshots will suffice.

 I have attached the pdf that I opened in the screenshot examples.


 Further information can be found on the QGIS forum
 ([https://github.com/qgis/QGIS/issues/45657]) and the GDAL forum
 ([https://github.com/OSGeo/gdal/issues/4701]) where I have orginally
 posted this bug.
