I just downloaded ImageMagick but am not sure if it's working. I typed in 'which convert' into my terminal and nothing happened. I also tried typing in 'convert logo: logo.gif' then 'identify logo.gif' and lastly 'display logo.gif' and nothing seemed to happen (these three commands were specified on Windows).
Then I tried following this video: http://www.youtube.com/watch?v=gEWAVlNCKhg
However, it still didn't work and on the last step of the video. I got the following error: ERROR: While executing gem ... (OptionParser::InvalidOption) invalid option: ----with-opt-include=C:/ImageMagick/SourceCode
Can anyone advise on how to correctly install imagemagick on windows or what these errors mean?
That video has a bunch of unnecessary stuff if all you want to do is get ImageMagick working as a standalone product on Windows. All you need to do is:
Note: when you run the convert command, there will not be any output to the command prompt unless you turn on the verbose flag e.g. (convert -verbose images\logo.jpg logo.gif)
