They have their uses, but for extracting individual portions of pages are nowhere near as convenient as being able to directly extract a graphical selection from the PDF viewer. (Yes, you can export a whole page image, then open in the GIMP or whatever and copy/save the selection. Anything is possible with enough effort; that's not what I was asking.) Sigh...apparently, this is another feature of Acrobat that is not yet implemented in free PDF viewers. (I wish the review had gone further beyond the "Can it open and print a PDF file?" level. The problem with many of these "grumpy editor" reviews is that they set the bar incredibly low compared to available proprietary software. I use, write, and love free software, but let's not close our eyes to where it is still deficient — in short, the grumpy editor is not grumpy enough for my tastes.)

Posted Nov 30, 2004 17:40 UTC (Tue) by larryr (guest, #4030) [Link] I personally do not consider selecting portions of images for copy/paste an important feature of a PDF viewer, or a web browser; I do think it is important to have software which can read PDF and produce image data which can be read by an image viewer which provides for selecting portions of images for copy/paste.

Posted Nov 30, 2004 23:11 UTC (Tue) by grantingram (guest, #18390) [Link] I agree with stevenj the ability to extract pictures from PDF files is extremely useful - I spend a lot of time reading PDFs at the moment and being able to get at images from them is quite handy.
Of course one can get around it - a more direct way than converting the entire file might be to take a screenshot and edit that in the GIMP - handy if you have a twenty page document.
I'm sure there must be some bit of software that will take bitmaps of arbitary bits of screen though...

Posted Dec 21, 2004 2:01 UTC (Tue) by freeid (guest, #22401) [Link] Silly enough I noticed that if you copy graphics from Acrobat Reader the bitmap will only be in the resolution you are viewing it. You can print the selection to a Postscript file though and thus get the full resolution. But it doesn't seem to work all the time...
Another annoying thing is that you still can't paste an image copied from acroread into Gimp. (In Unix that is, it allegedly works in Windows.) It works with Xpaint though.
