Issue occurs with monochrome tiff file using Group4 compression.

Note that if the image is encapsulated in a pdf file, for instance using tiff2pdf, so that the pdf file contains an image with group 4 compression, LibO still cannot insert it properly (in this latter case, it inserts a blank rectangle).

Issue is also present in LibO 6.2.

This is a regression since LibO used to be able to insert Group4 tiff images, even if there were some glitches.

OK, sorry for the noise... Looks like the tiff files were generated with some issue by the gimp. Other tools could manage them properly, but the files were much larger than they should have. Copying them with tiffcp "fixed" their size and the ability of LibO to deal with them. Issue with the pdf remains, though.
