For some websites that I run I fairly regularly need to resize some photos to a certain width. ImageMagick is a great application for command line image manipulation.
The syntax to convert a file to a specific width and the corresponding height (which is what I want to do) is:
convert InputName.jpg -resize 550x Outputname.jpg
What I’ve found useful is running command line scripts through vbscript:
Set wshShell = WScript.CreateObject(“WSCript.shell”)
wshShell.Run “cmd.exe /C convert InputName.jpg -resize 550x Outputname.jpg”, 0, True
I know you can do all sorts of clever things from the command line, but not quite as many as vbscript can. I find it really useful to be able to access all of the vbscript logic, and read and write text files and so on, while at the same time being able to issue commands to the command prompt.
