get dpi and unit

[ytzhiyuan]

When I use the following command, the result is as follows, which xresolution and resolutionunit should I take?

Code Select Expand

exiftool -a -G1 -s -XResolution -ResolutionUnit 550X120软中远cxT.jpg Picture url:https://newpy-upload-home.oss-cn-shanghai.aliyuncs.com/51694e81cbfb4388b1c398d9497f3589/鸭/550X120软中远cxT.jpg

I would take the one that ExifTool shows without the -a option (ie. IFD0)

I'd say it depends upon which one is used by the programs in your workflow.  Photoshop, for example, might prioritize to the ones in the photoshop block.
