Looking for a Script for Bridge..

[SDHRS]

Can anyone direct me where to build a script for Bridge.

I would like to build a script to convert the Dimensions (in inches) metadata to the dimensions if the the size was reduced to 3" on the largest side and put it in the description metadate line.

[Lumigraphics]

This can certainly be done, but be aware that images are measured in pixels and inches are a derived property. If PPI data is changed or deleted, the derived inch measurement will also change.

[SDHRS]

Thank you for the heads up.  Would it be possible to have the script over write itself up request?

[Lumigraphics]

I'm not sure what you are asking, sorry.

[SDHRS]

Oh, its likely due to my lack of knowledge on the subject.  I don't even know how to explain it properly.  I was simply confirming that, I could potentially be able to run the script again and replace the description again with the updated size as it would be based off the pixel data.

More so, is there somewhere where to start for the novice such as myself?

[Lumigraphics]

Yes you can change metadata at any time.

I already have a script that writes to the description, I'll post it here when I get time. Shouldn't be hard to modify.

[SDHRS]

I would greatly appreciate that.  Thank you,

This should work. Save as PLAIN TEXT with .jsx extension and copy into the Bridge Startup Scripts folder. Restart Bridge, select your files, right-click "Ratio to Description".

This script writes dims to description

First, thank you.  

I am however running into a bit of a bug and maybe you can help.  I've followed you instructions (to the best of my ability at least) and have tried to run the script.  I receive the following error code.  Easier to screen shot, but I can write it if you'd like.

[SDHRS]

ReferenceError:  XMPMeta does not have a constructor37

[Lumigraphics]

Ah yeah there is a library that has to be loaded, I updated the script above.

[SDHRS]

Thank you, it works perfectly.
