> What steps will reproduce the problem? SWF file available at: https://archives.clubpenguinwiki.info/images/archives/0/01/RoomsDance_2.swf > What is the expected output? What do you see instead? Matrix translateX/Y are off, when calculating from twips to pixels, doesn't match. What should be negative translateX/Y appears as 0, while positive translateX/Y doesn't correlate to actual pixel X/Y on 100% zoom. > What version of the product are you using? Is it "nightly build"? Which operating system do you have? OS: Fedora Linux 42 Using latest stable version of JPEXS: 24.0.1.

It is calculated correctly. See: The background shape is shape with chid 8. That shapes top left corner is located at coordinates -7800, -5000. Shape 8 is then placed into sprite chid 9 with matrix 0, 0, Sprite 9 is then placed into sprite chid 126 with matrix 7600, 4800. Sprite 126 is then placed on main timelines frame 1 with matrix 0, 0 If you add these numbers: -7800 + 7600 = -200 => -10px -5000 + 4800 = -200 => -10px You get -10, -10 pixel coordinates for top left corner of the background. See attached screenshots.
