I mean it shouldn't be too hard to implement in Dia as the diagram already has defined physical dimensions AND we know the scale at which it's being rendered, just need to hook into that Of course this would be implemented in C as aside from being complex to integrate Java is horrible, esp when we want to be packaged for Win/macOS Really it's just needs to be another overlay like selection boxes Unfortunately I just don't have time ATM to work on that right now, focus is on issue backlog and modernisation rather than new features > _______________________________________________ > dia-list mailing list > dia-list@gnome.org > https://nam01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fmail.gnome.org%2Fmailman%2Flistinfo%2Fdia-list&data=02%7C01%7C%7C404d3dfd51ea4aa05b0208d6dd86d0b5%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636939968428293804&sdata=RtxD8v7v8V%2B3vNOVXYxZ8esuq8ugKESkFe%2FaWobZNQM%3D&reserved=0 > FAQ at > https://nam01.safelinks.protection.outlook.com/?url=http%3A%2F%2Flive.gnome.org%2FDia%2FFaq&data=02%7C01%7C%7C404d3dfd51ea4aa05b0208d6dd86d0b5%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636939968428293804&sdata=lLPyOBP8AhiQixMV%2B1aRZw1XqBY2LZipQU%2FJg3BO1EY%3D&reserved=0 > Main page at > https://nam01.safelinks.protection.outlook.com/?url=http%3A%2F%2Flive.gnome.org%2FDia&data=02%7C01%7C%7C404d3dfd51ea4aa05b0208d6dd86d0b5%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636939968428293804&sdata=vN7Rs4VJ0nS%2BYxHgSQJuaYC1rS3JNHz%2FBYxe2c0xefI%3D&reserved=0 > -- Zander Brown <zbr...@gnome.org> GNOME Design Tooling (Icon Preview) Dia Diagram Editor
