Exactly, this number is only really meaningfull in the context of preserving the original dimensions of scanned documents, etc. If you *aren't* using a recent darktable build and need to set this field to make some people happy, you can use exiftool:
exiftool -xresolution=250 -yresolution=250 <filename> or, if you aren't always exporting to 3000x2000, create a script named '8x12.sh': width=$( exiftool -b -imagewidth "$1" ) height=$( exiftool -b -imageheight "$1" ) if test $width -gt $height then resolution=$(expr $width / 12) else resolution=$(expr $height / 12) fi exiftool -xresolution=$resolution -yresolution=$resolution "$1" and run it on the file before uploading. -- junkyardsparkle On 2014-12-04 [email protected] wrote: > Why would you want to set PPI to 72 for web content?
