I am looking to use live captions to display information about placed images. The end document with the placed images is ultimately not used by the art department but rather box engineers that work exclusively in inches. When I use the live caption to display the dimensions I only have the option to display in pixels. Is there a setting that i am missing that will convert the placed images dimensions into inches? I am using ID CS5 and the placed images are JPGs from Photoshop?
It took me a little research to figure out what you're doing. When you use Live Caption, you're pulling metadata from the file. Metadata is defined in a format called XMP, which was developed by Adobe. You can view metadata best in Adobe Bridge. If you select a picture and view the Metadata panel, you can see the metadata that's in file. In Live Caption setup you're apparently picking the "Dimensions" field, which is defined in pixels. There is another potential piece of metadata (Dimensions in Inches) but it is not filled in in the JPEGs. To figure out how to add a metadata field that is not in the file, you'll have to research how to edit XMP metadata. There doesn't seem to be a mechanism for editing that field in Adobe Bridge.
There's nothing in InDesign that would allow you to edit the field. Maybe someone could write a script that would edit the caption after it's in InDesign, and convert it to inches.
That would be the dimensions at "100% scale," i.e. at the resolution saved in Photoshop?
The dimension in inches field is there in the metadata, but apparently is not accessible to Live Captions, so seems like you need to find a way to do the math (or let the engineers do it). You can supply both the pixel dimensions and the resolution.
