How to get the number of images

[kankan_lee]

Some times the ImageMagick convert 1 file to a few images, named by -0, -1, -2....
How can I get the number of the images? I guess there should be some variable I can use directly.
Thanks!

try

Code: Select all

convert image -format "%n\n" info:

that will give you the total number of scenes repeated for each scene. So you have to do some further processing to extract just one of them.

see http://www.imagemagick.org/script/escape.php.

For example:

Code: Select all

convert rose: rose: rose: rose: rose.gif

Code: Select all

convert rose.gif -format "%n\n" info:
4
4
4
4

or in unix you can do

Code: Select all

convert rose.gif -format "%n\n" info: | head -n 1
4

Always best to provide your IM version and platform when asking question on this forum, since IM syntax and scripting differ between unix and windows.
