#702: 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.

     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.

 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. There is information and analysis there from folks.

 I have tried to attach files but they are too large to attach. Please see
 the QGIS and GDAL posts for the document and screenshots.

 Also, apologies if any of the settings (Type, Priority, etc.) are
 incorrect - first timer here, please feel free to edit.

 If you need any further info that I can provide, please do let me know.
 Many thanks in advance!
