The pictures of that documents comes from a print screen made in windows XP.

Those pictures are pasted into the document.

I've just tried again the document with LO 3.4.4 and the issue remains the
same.

Therefore, I have opened a PNG picture in The Gimp, copy it and paste it into
writer. Then I've cropped it and exported into PDF. However, it's working
properly. This confirms that these particular pictures might be the problem.

I've tried to save the Fig.7 into an image file (PNG), insert it in a blank
document, crop it and export to PDF… it's working properly.
However, when I've saved the image the image has been changed a little bit: the
"S" of Sobel became a little bit weird. Try yourself and see if it does that
too (have a look at the fig7_exported.png attachment).

Therefore, when the picture is saved, it has been changed—enough to see it on
the S of Sobel. This means the picture in the document might not be in a good
shape.

I've copied and pasted the Fig.7 into a new document, saved and exported: same
issue. (see alone.odt).

By opening the odt file with a archive manager I saw that the picture is saved
as a *.svm file which I can't open.

Therefore, I've looked into the ODF specification file. It says that "While the
image data may have an arbitrary format, it is recommended that vector graphics
are stored in the [SVG] format and bitmap graphics in the [PNG] format." (p.
298)
However, the SVM file isn't a PNG file. (nor a SVG one obviously)

p. 684, it says that "The manifest file is always stored at the pathname
META-INF/manifest.xml". However this file doesn't say anything about the svm
pictures...

That's all I have for now.
