Precautions with 7 or earlier

Details will come out soon, but from 7 the module name has been changed from `convert``` to magick```. Specifically, in windows, it changes from `` convert.exe `` to ``` magick.exe```. Therefore, in 7, the module name of ImageMagick in the argument of ``` new ImageMagickCmd``` needs to be `magick```. Please note that when referring to existing materials.

However, you can still use `convert```. In that case, it is necessary to check Install legacy utilities as shown below at the time of installation. If you check this, convert.exe `` will also be installed.
