Bulk resize images with image magick

When I need to resize images, in bulk (or even one at a time) and I want them to stay sharp, i use ImageMagick

> magick human_resource_machine.png -resize 200 -unsharp 0x6+0.5+0 human_resource_machine_200.png

This gives the file a width of 200 pixels, and a height in proportion to the current aspect ratio.

It also applies an unsharp filter, which sharpens the image (go figure!)

ImageMagick is here (and is in my path)

C:\Program Files\ImageMagick-7.0.7-Q16\magick.exe
