Yes, it is what I saw in pdflatex as well. Now I see the reason, I have not read my exiftool output carefully. It says: X Resolution : 25 Y Resolution : 7 Yes, that does look a bit weird, doesn’t it. One would expect it to be the same in both directions, unless specifically set to be different for a special effect. Notice that it also says Resolution Unit: inches . Surely not! unless it needs ~100 units for the inch. Further down there are Pixel units of meters. Very strange. Thanks in advance for any lessons on how to properly read/interpret this info. So the culprit need not be XeTeX after all. All the best. Ross So, pdftex as well as viewers used by Phil honour the resolution in both directions and the output is tall. Gwenview, gimp and ocular just honour the size in pixels. Xelatex probably calculates the dimensions correctly taking into account X/Y resolutions, generated the commands for PNG inclusion but xdvipdfmx honours the pixels only, not the resolutions.

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) <Screen Shot 2021-06-11 at 6.21.21 am.png> So to me, this looks like a XeTeX issue after all. Hope this helps. Ross On 11 Jun 2021, at 2:12 am, Janusz 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 Janusz -- , Janusz S.
