Re: Script to change what part of the image is shown

Documents have a property called "center" that can be assessed via Action Manager code, I don’t know how to feed it back, though.

Also I don’t think the Window’s dimensions are available, so it might be no use either way.

if (app.documents.length > 0) {

var ref = new ActionReference();

ref.putEnumerated( charIDToTypeID("Dcmn"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") );

var docDesc = executeActionGet(ref);

var theCenter = docDesc.getObjectValue (stringIDToTypeID("center"));

checkDesc2(theCenter);

};
