This image has a weird DPI. If I open it with GIMP and view Image - Properties,
it shows DPI as 2,834×2,834 px/mm. GIMP does export it correctly, however, and
even preserves the DPI.
With LibreOffice, to export an image in its original size, you need to
right-click the image and select Original size first. If we do it in this case,
the exported resolution is 990x400 and the DPI will change to 72x72 ppi.
So LibreOffice should learn to behave as smartly as GIMP.
