Can you run a test with this file? :o

What other format were you expecting? The tool extracts PDF image objects or the rasterization of the pages.
The above script just takes advantage of the tool page rasterization functionality, to create a rasterized PDF by merging all the generated page rasterization images files into a new PDF.

Worked fine. Check attachment.

If you have the ImageMagick tool still installed, as when you requested a "Script to count how many colour pages in PDF?", check if this ImageMagick based rasterization script works for you.

--- Code: ---var RenderDPIs = 120;
//================================================================================

var imo = new ActiveXObject("ImageMagickObject.MagickImage.1");

var ProgressBar = pdfe.ProgressBar;
ProgressBar.max = pdfe.SelectedFiles.Count;

for (var i = 0; i < pdfe.SelectedFiles.Count; i++) {
    ProgressBar.position = i + 1;
    try {
        var File = pdfe.SelectedFiles(i),
            Filename = File.Filename,
            Pages = File.Pages;
        var Path = Filename.substr(0, Filename.lastIndexOf('\\') + 1),
            Name = Filename.substring(Path.length, Filename.lastIndexOf('.'));

        pdfe.echo(' > rasterizing ' + Filename);
        pdfe.echo(' ');
       
        var NewFilename = Path + Name + '_rasterized.pdf';
        imo.convert('-density',RenderDPIs, Filename, NewFilename);
        pdfe.echo('     Saved to: ' + NewFilename + ' [OK]', 0, 2)
    } catch (e) {
        pdfe.echo(e.message, 0xFF0000);
    }
}
pdfe.echo('Done');

--- End code ---
Not so fast as the above solution, and the generated PDF is bigger in size, but should be less cumbersome.

You need to give me more details about what fails with the first script, so I can figure out what may be the cause.

In the image extractor tool (not the new script) I don't have the option of PNG or JPG or TIF etc?

In the help file / webpage it says that should be an option..

This solution was actually much faster.. ? The other is literally just stuck displaying this:
 > rasterizing O:\12010 COOKE & D\og\combined revised hyd-0001.pdf
 Page 1/1

I'll leave ot be and see how long it takes but at this point it doesn't seem to want to spit out a file.
