I was working on a powerpoint presentation and wanted to paste an image from a pdf file. There is no such provision in Acrobat Reader, as is seen in the desktop version. Also, I had seen that those presentations which I had made in my windows pc using the snapshot feature of Acrobat reader got pixelated when zoomed on the slide. While preparing slides on my new iPad3 with Retina Display, I was feeling a bit frustrated as the resolution was getting worse than the pc for those old presentations. However, today I tried to use the "Screenshot" from my iPad. I zoomed the picture I wanted to use and pushed the home and sleep button together.... I got a "Retina Resolution Image" from my pdf document. I can now use it from my photo album without any compromise on resolution!!
