find every text frame and set first baseline offset...

[dhishok]

Hi everyone,

I am currently working with InDesign CS2 files and i want to find all text frames and change its first baseline offset to "Cap Height". So I have tried the below syntax and it shows error. Please help me for this.

THanks in advance   

//==================

#target InDesign4.0

var myFrame = app.activeDocument.textFrame.everyItem();

for (var i=0; i<myFrame.length; i++){
myFrame.textFramePreferences.firstBaselineOffset=1296255087;
}
alert ('DONE');

//==================

Regards

var myFrame = app.activeDocument.textFrames.everyItem().getElements();
for (var i=0; i<myFrame.length; i++){
  myFrame.textFramePreferences.firstBaselineOffset = FirstBaseline.CAP_HEIGHT;
}
alert ('DONE');

What is the difference between the following two lines?

var myFrame = app.activeDocument.textFrames;

and

var myFrame = app.activeDocument.textFrames.everyItem().getElements();

In both cases the script works as expected. Why do you add .everyItem().getElements()?

Because everyItem().getElements() builds a static Array of the items.

Without it, it's a dynamic collection.

When you have a collection, there has to be interaction with InDesign

every time you access a member of the collection and InDesign rebuilds

the collection each time it's accessed. That means a lot of extra

overhead.

Bottom line: using a static array is almost always faster than using

collections.

Thank you , Harbs. Now everything is clear to me.

One important exception to this rule is with Text objects. With Text objects, I've found Collections to be more efficient than Arrays.

I think the reason for this is because Text objects don't really exist on the C++ level. Any time you access a Text object with scripting, InDesign must resolve that object within the whole text strand (which involves at least as much overhead as resolving the Collection). Page Items (and most other objects) on the other hand are basically mapped straight to the C++ ones so they don't need to be resolved in the same way.

If you literally want all text frames, including any that are part of a group or inline/anchored to another story, then you need to use:

myPIs = app.activeDocument.allPageItems;

for (var j = myPIs.length - 1; j >= 0; j--) {

     if (myPIs instanceof TextFrame) {

          myPIs.textFramePreferences.firstBaselineOffset = FirstBaseline.capHeight;

          myPIs.textFramePreferences.minimumFirstBaselineOffset = 0;

     }

}
