I have a pdf which I want to extract a high resolution / vector graphics format from.
When I open the PDF with Preview I can zoom in forever and artwork always seem to have a crisp edge. However when I open in Photoshop they appear pixelated at a certain resolution.
I have tried choosing the option "images" when opening, but it doesn't find the particular art I need.
Any suggestions? I'm not desperate to have vector, but just as high a resolution as is possible as I will be enlarging the figure by 1000% or more.
