[XeTeX] strange case of overlapping graphics

[Ross Moore]

Hi Janusz, and others

For me, using  pdftex, the only issue is that the aspect ratio isn’t correct.

XeTeX gets it wrong:

Notice the apparent lack of centering with respect to the caption.
It’s as if the width has been read incorrectly by XeTeX, for positioning
the 2 instances of the image.



Explicitly specifying a more realistic width fixes this, with both engines.
Examining the information in GraphicConverter  (on MacOS)
I cannot see anything amiss.  (see image)

So to me, this looks like a XeTeX issue after all.


Hope this helps.

Ross

Tomorrow I will make more tests and submit the problem to ddjvu
author(s).

Yes. It's great you have found a way to circumvent the problem!

On the other hand this make the problem more misterious...

Best regards
