Change invert to negate as the command option.

| Dec 19, 2018 at 23:25 | comment | added | Steve Barnes | @user3169 - the option is now -negate rather than invert - editing the above. | |
| Dec 19, 2018 at 19:29 | comment | added | user3169 | Thanks. I tried the example but got an error, "find: missing argument to `-exec' ". I could execute for testing purposes "mogrify -format png 01.jpeg" and it worked as expected. But when I checked the options for mogrify online, there was no -invert option. | |

Added example code

| Dec 19, 2018 at 3:14 | comment | added | user3169 | @AnonymousLurker OK, I got it. Guess I was trying to make it more complicated than it was. All I need now is to figure out how to loop through the files. Sorry, I am computer literate but not a scripting expert. I may need more help. | |

@user3169 , Ring gave you a self sufficient pointer to the docs with an example right there, it is as simple as convert blackandwhite.jpg -negate whiteandblack.jpg for one file . The only additional thing you need is to loop over your files and feed them to convert. Look for examples of find + xargs

| Dec 19, 2018 at 0:42 | comment | added | user3169 | Perhaps. I have never used ImageMagick before, but it might be overkill for what I am trying to do. At the least I would need some detailed instructions how to. I can ask that on SO if it would be a more appropriate site. | |
| Dec 18, 2018 at 18:20 | comment | added | NothingToSeeHere | Look at imagemagick.org/Usage/color_mods/#negate | |
| Dec 18, 2018 at 6:49 | comment | added | Izzy | That was my first thought as well; but does it support "invert"? If so, could you please include this with your answer? | |
