Maybe I have missed something but it looks like Valentina fixes the output resolution of “Image files” like PNG to 96 PPI (DPI). If I am not mistaken, the constraint applies to both the UI and the command line. I cannot find a way to change it.
I can see that everywhere there is a “Paper format” groupbox, the “Templates:” combobox items always reference PPI within parentheses eg: “Roll 44in (96 ppi)” in the “Create a layout” dialog and “A4 (96ppi)” in the “Save Layout” dialog.
Is it currently possible to set the PPI somewhere (eg. config file or an argument to the executable) so it is picked up for the session (UI and command line)?
