Paragraph rule

  • May 3, 2012

Hi All,

Is it possible to add a rule above or below my selected paragraph in the documents through Javascript?

In my document I require rule to cover whole paragraph (paragraph lines varies in the document) in selected paragraph style sheet named QUOTE.

See example below:

Please provide the JS code.

Thanks,

Kerosk

Hi,

if you can't get 'myParagraph.lines[-1].baseline' then you probably have a overflow of the paragraph in the text frame (shown as a red '+') ... and so it's not possible to get / calculate a position.

you can ignore it by try catch or write a function to calculate from the last line in the textframe in that case.

have a nice day

hi,

this should basically do the job ... column/page breaks are not considered.

Cycles thru the stories of the document to find a certain pStyle, modifies the existing rule below.

It's not perfect ;-)

var pStyleName, myDoc, mUnits, myStories, myStory, myParagraphs, myParagraph, offsetWeight, toAdd,  s, p

pStyleName = 'quote'  //the paragraphstyle to look for ...

myDoc = app.activeDocument;

mUnits = [myDoc.viewPreferences.horizontalMeasurementUnits, myDoc.viewPreferences.verticalMeasurementUnits];

myStories = myDoc.stories;

toAdd = 8; //to add to lineweight in pt; space above and below

main()

function main()

{

    setViewPrefs([MeasurementUnits.points, MeasurementUnits.points]);

cycleThruStories(myStories);   

        setViewPrefs(mUnits);

    }

function setViewPrefs(units)

{

        with(myDoc.viewPreferences){

                horizontalMeasurementUnits = units[0];

        verticalMeasurementUnits = units[1];

    }

    }

function cycleThruStories(docStories)

{

for(s = 0; s < docStories.length; s++)

{

    myParagraphs = docStories.paragraphs;

    for(p = 0; p< myParagraphs.length; p++)

    {

        myParagraph = myParagraphs

;

        if(myParagraph.appliedParagraphStyle.name === pStyleName)

        {

offsetWeight = (myParagraph.lines[-1].baseline - myParagraph.lines[0].baseline) + myParagraph.pointSize + toAdd;

with(myParagraph)

{

    ruleBelowLineWeight=offsetWeight;

    ruleBelowOffset = -(offsetWeight  - toAdd/5*3.5); //- toAdd/5*3.5 bit more or less space? ;-)

    }

}

        }

    }

    }

Thanks for the answer, Hans.

I have tried this code but it is giving error (The property is not applicable in the current state.). See screenshot attached.

I am unable to rectify this error. Please help.

Thanks,

Kerosk

Yes it is possible, although you need to answer the question: what do you want to do at column/page breaks? Your described techique won't work there.

But you seem to be expecting some kind soul to just write a script for you. That might happen, but most people needing a script who aren't prepared to write one themselves would look to hire someone to do the work for them.

Good luck.

I will do it manually. But need to apply pagragraph rule globally in document.

I write below code but don't know how to calculate paragraph height in paragraph length.

If anybody has done this before please add the required code in my below JS code.

var myDoc=app.activeDocument

var myRule=myDoc.paragraphStyles.item("QUOTE")

with (myRule)

{

ruleBelow=true

ruleBelowColor="Green"

ruleBelowTint=50

ruleBelowLineWeight=80

ruleBelowTint=30

ruleBelowOffset=-25

}

Thanks,

Kerosk

You can use the text baseline for that: http://jongware.mit.edu/idcsjs5.5/pc_Text.html#baseline

Read the baseline for the first and the last line. The difference between these is the exact "height" of the paragraph, usually a multiple of its leading (1). Calculate this in points to immediately feed the value into RuleBelowWeight. You'll have to manually find the difference to shift down, but I think you only need to do this once.

(1) If all of your paragraph text uses the same leading, this would simply be

someParagraph.lines.length * someParagraph.leading;

-- but not if it's set to Auto, though (still possible but then you'd use autoLeading and pointSize instead).

... Why are you changing your paragraph style in your sample? Are all of your "QUOTE" paragraphs exactly the same amount of lines?
