How to avoid empty space in the inside of the equations

[kanagakumar]

Dear Team,

I need to avoid the empty boundary space around equations inside the frame. I have to exactly fit the equation such that there is no white space. Can you provide or suggest any script related to this request?

Please advise.

Or any option available in the mathtype to fix this issue?

Please see the screenshot for your reference below:

Thanks

You are right, Robert. Still, if it were my task, I would do this step first anyway—after all I assume they would want the baselines to align. Therefore any cropping required will only be on the left and right sides and, because the script fits frame to content,  it means that if OP decides that the equations need a consisent amount added or subtracted from the sides, than the script can accommodate easily.

That wasn't my point. 

But to be fair - I see a benefit in your approach - AnchoredObjectSettings instead of Character's BaselineShift. Probably quite significant in some situations.

If it would be so easy to just crop few pixels on the right & left for all equations in the document - it would've been done long time ago and OP wouldn't ask about that.

I've done it long time ago - 2009:

But there are at least two methods to precisely crop equations.

Hi Mark, Thanks for the code.

I wonder if an alternative would be a Place script? The eps files have to get placed at some point, and on a place I don’t think you have to worry about the scale and parent bounds because we know the placed scale will be 100%, and the eps and its container frame will have matching bounds. You could also get the surrounding text range and set tracking or apply a Character style to handle the left right spacing. Something like this:

var s= app.activeDocument.selection[0];

if (s.parent.hasOwnProperty("baselineShift")) {
	var e = File.openDialog("Select an EPS to Place", "");
    if (e!= null) {
        s.place(e);
        //baseline shift the placed eps
        s.parent.characters[s.index-1].baselineShift = -getBaselineOfEPS(e);

        //optionally track the text range before and after to adjust the left and right spacing
        var tr = s.parent.texts.itemByRange(s.parent.characters[s.index-2], s.parent.characters[s.index]);
        tr.tracking = -50;
    } 
}else{
    alert("Please Select an EPS to Insert")
} 

/**
 * Returns the `baseline` value
 * from the EPS file.
 * @ author Peter Kahrel
 * @ author Rob Day
 * @ author m
 * @ version 2024-03-09
 * @ param eps file path
 * @ returns {Number} - the baseline extracted from the file.
 */

function getBaselineOfEPS(f) {
    f.encoding = 'BINARY';
    f.open('r');
    var str = f.read();
    f.close();
    try {
        return Number(str.match(/%%Baseline:\s(\d+)/)[1] || 0);
    }catch(e) {
        alert("The Placed File Has No Baseline Info")
        return 0
    }  
};

@rob day Looks great! And we would definitely want a version for cases where the equations weren't already anchored in the story.

In most cases I would prefer to adjust the anchored object settings rather than baselineShift, but that's just me.

Dear m1b,

This script perfectly aligns the base-align, but the left and right sides show extra space due to the empty space in the inside of the equations (padding space).

This case only i'm doing maull work now. It is excellent script.

   

Thank you very much "Mark"

Thanks

You can add tracking before and after the equation. Should be easy to add to the script, but you can do it in the interface as well with two GREP queries:

Find what: .(?=~a)

Change to: <Leave empty>

Change format: some negative tracking

Find what: ~a\K.

Change to: <Leave empty>

Change format: some negative tracking

[Peter Kahrel]

That one is unnecessarily complicated. One query will do it, it applies tracking to any character  followed by an inline followed by any character. It also works at the end of a paragraph:

Find what: .~a

Change to: <Leave empty>

Change format: some negative tracking

[kanagakumar]

Thanks for your coding Mr. Peter Kahrel

@kanagakumar I have edited my script above to include settings for "leftSidebearing" and "rightSideBearing"—these are the offsets (in points) on left and right sides of each equation. Try it out.

[kanagakumar]

Dear Mark,

Thank you very much for your coding.

After the script was executed, below the display equations merged into the paragraph lines. I need two pica of visual space for the display equations below only.  Inline questions no issues.

Display equations are controlled by the paragraph styles:

EQ, EQ-f, EQ-m, EQ-l

My requirement:

Thanks

Hi @kanagakumar, I just need to get the script to know which is which. It looks like if the anchored item is the first character of a paragraph then it is a "display" equation. Is that correct? Can you please share that large equation .eps and a little demo text .indd? It would help.

- Mark

[m1b]

Hi @kanagakumar, I have updated the script above to try to handle "display" equations, assuming—for now—that these are equations that follow a carriage return or forced line break character.

You should make an Object Style for each type of equation, that at least has the Anchored Object Settings. These are what I suggest:

Do you see where is says 2pt space after? You can change that to your needs.

Let me know if I have guessed correctly and that it works the way you want.

- Mark

[kanagakumar]

Dear Mark,

Yes, Correct. Your script adjusts the points in the anchor object panel.

Now i fixed the overlapping issue using in the object style "Text Wrap" option. And i will apply manaully this object style name  for each display equations.

Before style applied:

After style applied (object style name -- "Eq-text Wrap"):

Only the paragraph styles "EQ" and "EQ-l" will require this object style to be applied; No need to be applied globally. All of the issues have been resolved if this script add an object style name. Is it possible to apply this object style name to this script based on paragraph style name "EQ" and "EQ-l"?

Or how to add object style name "Eq-text Wrap" in the perticular paragraph styles "EQ" and "EQ-l"? Please advise.

Thanks

kk

[m1b]

Hi @kanagakumar, I have adjusted the script above. You can see the "isDisplayEquation" function now checks the applied paragraph style. If it is "EQ" or "EQ-I" then it will apply the object style you name in settings equationDisplayStyleName variable. I hope that makes sense.

- Mark

[kanagakumar]

Dear Mark,

The revised script is not executing in an object style, and the equation number is not aligned with the equation center.

Paragraph style:

Object style is not applying:

Thanks

kk

[m1b]

Can you send me a little demo .indd file with that text so that I can explain what is going wrong? For example in the script I used the ParagraphStyle names "EQ" and "EQ-I" and these must be exact or the script will not change them. There are a lot of factors that could be causing the problem, but if you post an example document I can test properly.

- Mark

[kanagakumar]

Dear Mark,

Kindly apologize for the delayed response. Kindly see the attached recording file for your reference.

Little bit modified in my side. I need text wrap option inlude in this script directly.  No need to add obejct style request.

After run the script equation 7.22 is not center align the equation number:

Thanks

[kanagakumar]

Dear Mark,

Once again, I'm thankful. Your script reduces my lot of manual effort and increases efficiency.

Thanks

From the screenshots - you are working on a PC, right?

Would you need more options - greater control over individual equations and batch processing of INDD files?

And I can see that you work with XML, right?

[kanagakumar]

Dear Robert,

Yes, I am working on a PC

This is an XML workflow in InDesign.

Thanks

You might as well post it here. We all know what'll be in it 🙂

I've just asked what extra functionality he would need. 

Import of the equations and setting baseline have been done for years - but after that, with my tool, you can completely forget about using mouse and only use keyboard - so it's much faster and more convenient.

And if you add bulk processing of files... 

And sometimes, people don't get notifications about messages sent on priv - like me, I've everything set up correctly - yet I don't receive emails about private messages.

Dear Robert,

Thank you for your support.
