Normally I find I can extract an image from a PDF by selected it, copying it, then pasting it into an image program such as MS Paint.
However, I have a series of PDFs where, if I try this, the image is black.
The Snapshot functionality is not appropriate here since that can only be used to select a viewable area onscreen and in this case the image is much bigger than the screen (and if I zoom out, the resulting image is low resolution).
Any help appreciated,
No, it's for Reader. Yes, one can indeed copy and paste images from Reader.
Sorry. "Copy/Paste" and extract are two different things. Copy/paste will work yes but "Extract" is an actual feature of Adobe Acrobat that will pull images at their set resolution. "Copy/Paste" won't do that.
It could be that the image has a transparent layer on top of it. PDF's can have several layers and they can be on top or behind the image. If it's on top, you may have to us the snapshot tool.
The link above to "Forum" does not work.
I'm experiencing the same. Did you ever find a resolution to this? Thanks!
This worked for me: right click on the area you selected, then instead of "copy image" hit "copy with formatting".
