Strange behaviour on PDF graphics in DITA files

Report · Mar 02, 2022

I have DITA files that use PDF files as graphic objects. The first one is fine, the second one gets scaled down to about half its size, the third one to about 3%. I have no idea what is causing this but it looks like some internal variable that is not being reinitialised with every new PDF import.

But in any case, I would expect the height and width attributes to be used. It seems that scale is overriding these and when scale is not defined something crazy starts happening. When I manually change the height and width, the same crazy scaling reappears after saving and reopening the file. Only when I set the scaling to the correct percentage are graphic sizes kept when saving and reopening the DITA file.

Does anyone else have similar experiences with using PDFs as graphic files in DITA ? Is there something I am missing here?

When I manually set the height and width to the values from the DITA file, the image size is correct.
