Bug reports / Extract Images (no append option?)

« Last post by nightslayer23 on April 17, 2024, 05:43:45 AM »

Hey, when using the extract images function, the only options to handle duplicate filenames or images is to:

• Replace It
• Skip Name

There however should be an option to save the duplicates? Append filename?

Ideas/Suggestions / Re: optimize PDFs for machine learning / AI model training

« Last post by RTT on February 26, 2024, 02:48:50 AM »

There are functionalities to extract text, with the possibility to get font information (name, size,...), but not to edit it.

Take note it's not easy to segment a PDF in order to isolate these parts you want to remove. Internally, for the worst-case scenarios, you may have a "goto xy" and "print command" for each of the characters, without any specific order. There is no indication of what is a word, paragraph, etc. You need functionality like the used in OCR tools, that are able to provide that type of feature extraction in a useful format like hOCR.

Ideas/Suggestions / optimize PDFs for machine learning / AI model training

« Last post by edgaughan@hotmail.com on February 24, 2024, 11:58:19 PM »

My company trains and grounds Large Language Model (LLM) with PDF files. The problem is the valuable part of a
PDF is the body text, while the Table of contents, footnotes, index, and headers/footers create problems (especially with semantic search).

Do any of your utilities allow for batch processing of files that will:
- delete all text below a point size (ie delete text =<9 points will remove foot notes and index)
- remove Table of Contents
- remove all text in margins 

There is a lot of demand for a user-friendly tool that preps PDFs for machine learning.

You have to escape the backslash characters in a JavaScript string.
var PDFShellToolsExePath = "C:\\Program Files (x86)\\PDF-ShellTools\\PDFShellTools.exe";

Take note that you can use the scripts API from an external script directly. No need to call an internal script from an external one. You just need to register the pdfe root object (check the attached screenshot), and then initiate it as usually with any other ActiveX object.
var pdfe = new ActiveXObject("MyScripts.PDFEObject");

Thanks. cool. parameters works...
I would  ask, how I can run a custom script rename files with a shortcut
I tried with this script but it doesn't work for me

CallShellTools.js shortcut: C:\ProgramData\Microsoft\Windows\Start Menu\Programs\PDF-ShellTools
Target:  C:\Temp\CallShellTools.js Script  RunScript "ScriptName=test"

Code: [Select]

var PDFShellToolsExePath = "C:\Program Files (x86)\PDF-ShellTools\PDFShellTools.exe";

var ShellApp = new ActiveXObject("Shell.Application");
var SelectedFiles = [];
var Windows = ShellApp.Windows();
for (var i = 0; i < Windows.count; i++) {
    var Window = Windows(i);
    if (Window.FullName.toLowerCase().indexOf("iexplore.exe") == -1) {
        var SelectedItems = Window.Document.SelectedItems();
        for (var n = 0; n < SelectedItems.count; n++) {
            var SelectedItem = SelectedItems.Item(n);
            SelectedFiles.push(SelectedItem.Path);
        }
    }
}
if (SelectedFiles.length > 0) {
    var SelectedFilesList = SelectedFiles.join(';')
    var ArgumentsList = '';
    for (i = 1; i < WScript.Arguments.length; i++) {
        ArgumentsList += '"' + WScript.Arguments(i) + '" ';
    }
    ShellApp.ShellExecute(PDFShellToolsExePath, WScript.Arguments(0) + ' ' + ArgumentsList + ' "' + SelectedFilesList + '"', '', '', 0);
} else {
    var sapi = new ActiveXObject("sapi.spvoice");
    sapi.Speak("No files selected");
}

General / Re: function parameters

« Last post by RTT on January 28, 2024, 03:38:29 AM »

You can pass one parameter to the script using this notation:

[ScriptName](parameter)

and access it from the script, as a string type, with CurrentField.value

Using your example, the expression needs to be:
[f]_[test](value)

And the script:

Code: [Select]

function test() {
    var dt = new Date();
    var dx = dt.getDate() + CurrentField.value;
    return dx
}

The parameter can be the result of another expression:
[ScriptName](1,5,3,[script2])

Because in this case it contains a separator, you can emulate passing multiple parameters:
var parameters=CurrentField.value.split(',');

Hello!

With the rename tool , can I use parameters in a javascript function?

Code: [Select]

function test(x) {
    var dt = new Date();
    var dx = dt.getDate() + x;
    return dx
}

Ideas/Suggestions / Re: Video Tutorial

« Last post by RTT on January 08, 2024, 03:50:08 PM »

Yes, video tutorials would be nice to have but I'm not good at it. But I offer free licenses, if someone want to make some.
You have the user's guide and can always ask, here in the forum or by email, if something you want to do can be done and how.
Regarding the release of new versions. I will eventually release new versions (many new things already implemented) but I need to find time to fix some issues, regarding some core changes (database related) that I want to introduce in the next release.

Ideas/Suggestions / Video Tutorial

« Last post by dohnjoe on January 07, 2024, 12:27:05 PM »

Hi
I have been always fascinated by editing and organizing PDF files.
PDF Explorer is very special in this regard because it has database features, lots of tools, batch operations, etc.
Yet for some reason, I have a hard time using all its features.
That is why I would be very grateful if you recorded a video tutorial which shows all its intricate features.
Thank you in advance.

PS
Any chance of releasing a new version?

Thanks for your prompt reply.  Now I know the issue.  The counter variable works fine to me.  Waiting for the next release!
