I was making a small guide for facebook users on mogrify and convert ImageMagik subcommands, but I found that convert has -sample and -geometry options that for me look 99% the same.
What is the difference between the two? And if by chance, how do they differ from the mogrify version of -resize, -resample, -sample, -scale?
Just to make sure when to use them and why (in case of specific formats, sizes, colors, etc..)
