I work for a software company that makes software to work with Photoshop, and one of our clients is having an issue where his images are always coming up with pixels per cm as the measurement. We have tried changing the Photoshop preferences to use pixels per inch, but this doesn’t change. On my system, it always comes up as pixels per inch. Is there another place where these settings can be changed?

The software that we make uses Photoshop scripting to set the image information, and our software always uses pixels per inch. The client is using Windows XP, and connects to Photoshop CS2.

If your client is, for instance, using "rulers" and changing the unit of measurement to cm (in a script or action perhaphs), that in turn will override the Preferences and set Photoshop to globally use cpi instead of ppi.

Hi Ian,

If you are using scripts you need to wrap the script in some controls in order to preserve the ruler units that are set in the preferences.

Something like this.

var originalRulerUnits = preferences.rulerUnits;
preferences.rulerUnits = Units.PIXELS;

– – – – – – – – – –
Body of script here
– – – – – – – – – –

preferences.rulerUnits = originalRulerUnits;

This will preserve whatever the ruler units are in the preferences, change them to Pixels for the duration of the script and then change them back to the original settings when the script is done.
