    I've unzipped the download, placed it in Program Files folder. Now, I'm supposed to open up "sample-xpdfrc", make some changes and save it to ??

    I get all of this except why is the square root of -1 = i?
    As Tren said: its a fundamental mathematical rule.

    Its a batch command but it will look at a PDF and rip out all images for you.

    I then resize the images using XNConvert which is also fee and available from https://www.xnview.com/en/xnconvert/
    I also use both these programs and can recommend them.

    Thank you and everyone else for the reply. I'm in the process of converting my old 2E home brewed campaign for 5E. Then I will need to convert it to FG once I get all of the necessary modules.

    The way I do it is:

    (1) create a new folder e.g. "C:\PDFimages". also create another folder in the newly created "C:\PDFimages" called "images"
    (2) download ftp://ftp.foolabs.com/pub/xpdf/xpdfbin-win-3.04.zip
    (3) extract pdfimages.exe from the zip file and copy it to "C:\PDFimages". You may find the other programs usefull - but we do not need them for this exercise.
    (4) create a file in "C:\PDFimages" called "run.bat" containing the command "pdfimages.exe -j z.pdf images"

    Whenever you want to extract all images from a PDF, copy the PDF into "C:\PDFimages" and rename it to be "z.pdf". Next double click the "run.bat" file which will execute the program extracting all images to the "C:\PDFimages\images" folder.

    You can then use the XNconvert to resize/rotate as required.

    One thing though, watch changing file formats due to the transparency level in the images. It maybe best to stick with PNG files.

    Hope this helps....

    Thank you, that helped a lot. I was a bit confused about whether or not I had to do an additional install. I was able to run pdfimages from a command line.

    I have an additional question, that you might be able to help with.

    I ran pdfimages -j on a pdf file and I get a mixture of .jpg and ppm files.

    The jpgs are negatives of the original black and white images.

    Any idea why, and if I have any options to change the contrast scheme back to the original?

    Again, thanks for your help!

    No problem - not sure about the negetive jpg files. What about the PPM files - do they contain the images you need? Paint.Net / Gimp should be able to open the ppm files if you are having problems.

    I have noticed that pdf's behave differently - I think its to do with they way they are put together by the publisher.

    Gimp will invert the negative images for me, still strange why it happened on this pdf. - Frandor's Keep (legally purchased pdf). The color images seem to be unaffected.

    Now that I look at the ppm files, I am uncertain why they were pulled out. They open with libreDraw by default and each seems to be an icon for a link to the table of contents, which I don't need. I guess the icon is an image.
