how to rename extracted pages with JavaScript

[ENE5CD9]

Hello. I have a 28 page pdf file. I would like to create a button that allows me to extract page 5 and rename it before saving it in the documents folder.
With another button, I would like to email as an attachment page 5 renamed.
I found this:
var cToAddr = "apctr@example.com"
var cSubLine = "Paperwork"
var cBody = "Here is your paperwork."
var page0 = this.extractPages (5);
page0.mailDoc ({bUI: true, cTo: cToAddr, cSubject: cSubLine, cMsg: cBody});
page0.closeDoc (true);
This works, but I can't rename page 5 of the pdf.
Can anyone help me please?
Thank you

You do that by specifying the cPath parameter of the extractPages method, but that requires running this command from a trusted context (such as a folder-level script). Can you install a script on the local machine of each person who is going to be using this file? Also, this will only work in Acrobat, of course, as Reader can't extract pages.

I thank you for the answer. The file is used by a single user with acrobat dc.
The path to the file is C: \ Users \ Tabene \ Documents
Can anyone help me to compose a script?

[try67]

How do you want to name the file with the single page?

I want to call it "QUESTION". 
Thank you

Then the value of cPath needs to be: "/C/Users/Tabene/Documents/QUESTION.pdf"

Read Thom's tutorial to learn how to set up this trusted function.

Hello. I have a 28 page file. I want to extract page 5. Then I want to save the page with a new name in a folder.
As suggested to me, I read Thom's tutorial, but I didn't come up with anything.

Save or to extracting pages to a named file requires a trusted function. It can't be done from a script in a docuemnt. The article outlines the methodology for saving a file and provides the code. 

This article is more general:

This article shows how to write a custom SaveAs function. This function can easily be modified to extract your pages to a specific file name. Or it could be used as with your existing script to save your extracted pages to a file with a specific name.

Hello. I have read Thom's tutorial.
I was able to get this feature to work
var oMyDoc = this.extractPages (5)
app.execMenuItem ("SaveAs", oMyDoc);
Page 5 is extracted and the save window opens.
The pdf page is so named "A9Re8zj55_hnmzv_nnw.tmp.pdf".
I tried to insert a script to locate a destination folder:
var oMyDoc = this.extractPages (5)
var cPath = this.saveAs ("/ C / Users / Tabene / Documents / QUESTION.pdf");
app.execMenuItem ("SaveAs", oMyDoc, cPath);
Does not work. Page 5 is extracted and that's it.
Even the only function this.saveAs ("/ C / Users / Tabene / Documents / QUESTION.pdf");
does not work

[Thom Parker]

The extracted page is in "oMyDoc", but the "saveAs" call uses the current document, i.e., "this", so it is the current document that is renamed. The code needs to use the document object of the extracted page.

oMyDoc.saveAs(...);

The call to execute the "SaveAs" menu item doesn't do anything.

[ENE5CD9]

Thank you for the help Thom.
I changed the function like this:
var oMyDoc = this.extractPages (5)
var cPath = oMyDoc.saveAs ("/ C / Users / Tabene / Documents / QUESTION.pdf");
app.execMenuItem (oMyDoc, cPath);
The formula doesn't work.
Page 5 is extracted, but it is not saved in the directory.

Hi
i open the console with ctrl + j.
I tried this formula:
var oMyDoc = this.extractPages (5)
var cMyPath = oMyDoc.saveAs ("/C/Users/Tabene/Documents/QUESTION.pdf");
app.execMenuItem ("Save", oMyDoc, cMyPath);
It works.
If I put the formula in a button it doesn't work.
I need to build a trust with a Trusted Function to be placed in the javascript folder.
I've read the instructions on this page, https://www.pdfscripting.com/public/Using-Trusted-Functions.cfm, but I can't build a function that works.
Please, can anyone help me?

[try67]

You don't need to use execMenuItem, saveAs does the same thing. You do need to run it from a trusted function, though

[ENE5CD9]

Yes. But I can't build a trusted function

[try67]

Why not? You have all the information needed.

If you still can't figure it out you can always hire someone to do it for you.

[ENE5CD9]

Can you help me? I am willing to pay you

[try67]

Yes, you can contact me via [try6767 at gmail.com] to discuss it further, including the price.

Message me through this forum and we can work something out.  What you are asking for is a small job.

Hi
I have a pdf file of many pages. I would like to extract the pages, rename them and save them in a path. I have to extract from page 1 to page 4, then page 5, then page 6 to 8 etc.
I created a button and entered the following function:

var Doc = this.extractPages (5)
var Path = Doc.saveAs ("/ C / Users / Tabene / Documents / QUESTION.pdf");
Doc.closeDoc (true);

In Adobe's Javascript folder, I have placed in file with ".js" extension containing the following function

var Trusted_MyDocSave = app.trustedFunction(function(Doc)
{
app.beginPriv();
Doc.saveAs(Doc.path);
app.endPriv();
});

I closed and reopened the pdf file. I pressed the button, but only page 5 is extracted.
I tried the button formula in the acrobat console. It works.
After pressing the button in the console this message appears:

NotAllowedError: Security settings do not allow access to this property or method.
Doc.saveAs: 2: Field Button1: Mouse Down

[try67]

Why aren't you using the trusted function you've declared?

[try67]

Also, this trusted function will not do what you want. It will just save the under its current path. You need to provide the new path as another parameter to it.

[ENE5CD9]

The path always remains the same, because I want to save pages 1 to 4 and page 5 etc in the same folder creating different files each with a different name.
In the example I wrote only this.extractPages (5) because I imagine that for the other extracted pages it will be enough to repeat the function

[try67]

It doesn't matter if it stays the same, you still have to specify it. You can either pass it as a parameter or hard-code it into the code, but it needs to be somewhere.

[ENE5CD9]

For a formula like this
var Doc = this.extractPages (5) etc ..........
I have to write a trust function, instead for a formula like this
var Doc = this.extractPages (1,5)
var Path = Doc.saveAs ("/C/Users/Tabene/Documents /QUESTION.pdf");
Doc.closeDoc (true);
I have to write a new trust function,
if I write: var Doc = this.extractPages (6,10) another trust function and so on.
Is that so, did I understand correctly?
