Here is how you can take out the same words from a PDF several times at once, without wasting too much time or effort.
Here is how you can take out the same words from a PDF several times at once, without wasting too much time or effort.
I bought a PDF that already has this stuff in it. It's all written out and green underlined. No way am I going to have to go through every single line and erase them manually. Why is deleting one by one so slow? Is there a better way to do this quickly without doing the work over and over again?
If things are the same size and can be found in the computer, then there is only one way I could think about doing this: Install Libre Office and open the PDF file in Draw. Then write a script (in Python or Visual Basic) to look for text that matches exactly. But, as far as I know, there are some big problems that might make this fail for you at least once: You need to be able to go through every object inside Libre Office Draw. Those objects have to all look the same in style. From my experience with PDF files (especially vector graphics imported from Inkscape), even when things look almost identical, it's a huge mess trying to tell which parts are different...
The green text you see might just be an illustration in the picture, so changing it probably won't work anyway. Also, your "printable version" link isn't editable because it's inside a photo. Even if you bought that PDF file as a download, it's likely protected by copyright law, which means making any changes is not allowed without asking for permission from someone who owns the rights to do so.
You know why these files come in a special format. Your question is similar to asking, "How can I take the eggs out of a cooked ham and egg dish?" You simply aren't allowed to do that on your own. You don't have full control over this book—you only bought the permission to read it.
If the objects are the same and easy to find, I can only think of one way: Use Libre Office and open the PDF in the Draw tool. Then write a script (in Python or Visual Basic) that looks for repeated text snippets. But there are several problems we might hit, at least what I know so far: You need to be able to go through all the document objects in Libre Office Draw. The shapes themselves have to look alike. My experience with PDF files is that even when they look very similar, it's like a huge mess trying to tell different parts apart. Text can also cause trouble. And finally, the content might just be a static picture, like an embedded JPG file inside the PDF.
