--- Comment #7 from WN <wilhelm.nues...@fhdw.de> ---
I'd like to second Roberts remark.
Exporting the same odg-File with LO 6.1 gives the following png information
obtained by imagemagicks identify -verbose:
Format: PNG (Portable Network Graphics)
Mime type: image/png
Class: DirectClass
Geometry: 1183x925+0+0
Resolution: 118.3x118.3
Print size: 10x7.8191
Units: PixelsPerCentimeter
Type: TrueColorAlpha
...
Exporting the same file with LO 6.4 and 7.0 from LO website the header reads
now:
Image: TCP-Header.png
Format: PNG (Portable Network Graphics)
Mime type: image/png
Class: DirectClass
Geometry: 1183x925+0+0
Units: Undefined
Type: TrueColorAlpha
Obviously, the fields resolution, print size are missing and
the field units is left undefined.
Using the standard equation:
no_of_pixels = dpi * inches
the information in the new header format is not sufficient to deduce the size
and/or the resolution. gimp, inkscape, imagemagick et al thus have to assume a
resolution ... and choose the standard of 72.
IMHO this looks really like a regression in the 6* series to me...
BTW: platform for tests is Linux Mint 19.3
