In 6.4.0.3, the PDF Options dialog displays 0 bytes, but the actual PDF export shows a non-zero byte file size. Whereas in 7.0.3.1, both the dialog and exported PDF file show 0 bytes. So this may not be the best indicator to use for this specific bug (might be a separate bug altogether).
In 6.4, you could rename the file with the .jpg extension and it would show the image. It was exporting the file as a jpg but with PDF as the extension. In 7.0, we get the 0-byte file. Same in Calc. Bibisected with the linux-64-7.0 repository to 2f93d2a88f8daf268f9554bd0c82cde4056a8546 which points to core commit 36962d9cc105d2c98889ee841438823fce090dfb which is a cherrypick of: commit 7272a2edf113f29edeb8987ce649f85b776d9d23 author Julien Nabet <serval2412@yahoo.fr> Tue Jul 07 10:23:28 2020 +0200 committer Julien Nabet <serval2412@yahoo.fr> Thu Jul 09 09:10:54 2020 +0200 tdf#60684: graphic type content must correspond with graphic type extension Reviewed-on: https://gerrit.libreoffice.org/c/core/+/98239 Not calling it a regression, as before that commit the export was already wrong. But Julien, what do you think?
JPG a raster format saved in a vector graphic data type (here PDF), I don't know at all what should be done here. Of course, feel free to revert my patch if you feel like.

Fully agreed that it is an odd use case, so we either: - get rid of this particular filter path; or - we make it work in an acceptable way (e.g. embed a bitmap inside a single-page PDF of page size equal to the size of the bitmap) I had a look at a bit more history, and the PDF option is only available since libreoffice-5.3.0.0.alpha1. Let's make this an implementation error from back then, and see if someone can bibisect what introduced it.
