Occasionally I have need to extract image files from PDFs. For some reasons, these images are sometimes rotated by 90 or 180 degrees. Fortunately, there is an easy way in Linux, using ImageMagick, to fix this problem. To rotate all images in a directory saving the rotated images back to the original filename, issue a command similar to the following:

for file in *.png; do convert $file -rotate 90 $file; done

For more information on how to manipulate images from the command line using ImageMagick see: http://www.howtogeek.com/109369/how-to-quickly-resize-conver t-modify-images-from-the-linux-terminal/
