extracting pix from PDF

i have never quite understood how to do this "elegantly" -- cut/paste doesn't work and nothing on the file/edit pulldowns seem to help.

cut/drag down to taskbar and release into folder at least gets the job done (usually...read on), but it feels muy "kludgy" to me. how are you actually SUPPOSED to do it?

anyway, lately i am finding a few pix which show up BLACK after I release them. the files are far from empty -- 100k, 250k, things like that -- but the images are completely gone (or 3/4 gone in one case).

i am sure i have dragged SOMETHING into those files - why can't i see them?

my gut feeling says that it has something to do with "layering", like in photoshop. i.e., my pic IS there, but somehow i've dragged a diff level of solid black along with it, and somehow "bumped" it to the foreground.

just a gut feeling. i'm all ears to alternative theories. why does a perfectly visible pic in a PDF turn solid black when dragged into some 178k (say) .BMP file??? more importanly, how do i OVERCOME it?

happening on about 1 in 10 pix.

your second suggestion is like a screenshot. it may COME to that, but for right now, i'm still trying to work with what's THERE. it's a image IN the pdf -- i.e. a BMP/JPG/GIF/etc file itself - im just trying to "extract" it.

besides which, i don't have "paste" available for the last step, even if i wanted to do it your way.

i'm giving somePDF a try, altho that feels like a "kludge" itself. and my first stab didn't work to boot!

 

thats what I was going to suggest. Although I seem to remember having to download a fix to get a screenshot of a movie once. I will look into it further.

 

The very FIRST extract with SomePDF worked muy weird (massive folder full of PBM and PPM files) but just fine every time since. And the otherwise "black" files are displaying just fine.

I am no expert on protected" files, but I did look at properties, and all the "allow sharing" "allow extracting" type options were checked. Plus, 90% of the pix extract just fine, including most other pix in the SAME DOCUMENT as the ones that I can't grab.

"Paste" exists in all sorts of other areas in Windows, but when I "cut" on a pic in one of these PDFs, the "paste" does not make itself available for dumping the pic in explorer. Instead I have to "cut" it, DRAG it while HOLDING, and RELEASE it into said folder. Which works just fine, except that the pic is now a BMP.

Are they, in fact, BMPs to begin with? Is SomePDF doing conversion to JPG as part and parcel of its extraction? Is there some other tool that will just extract them AS IS?

One other thing bugging me is that I have to extract and then hunt through the ENTIRE SET of pix extracted -- several HUNDRED in most cases. Isn't there some way Windows is supposed to just be able to GRAB the pic you're highlighting?
