How can I use a code result with a variable

Question

I can get result with this bat file that I want. However I can't use this result!

@echo off
identify -format "%%wx%%h" E:\Image.jpg

Result:

640x480

I tried something like this ...etc, but they don't work:

set var=%%wx%%h
echo %var%

How should I do this, thank you so much....

cmd's way to get the output of a command is a for /f loop. The following should work (untried):

for /f "delims=" %%a in ('identify -format "%%wx%%h" E:\Image.jpg') do set "var=%%a"
echo Result=%%a

See for /? for details about the loop format.

Note: this works best when the command outputs just one line.
