identify -format problem

[joshrobe]

When I use the command...

identify -format "%w %h %P" image.jpg

it returns something like...

120 180 %P

All special characters beginning with % work EXCEPT those in uppercase (C, D, O, P, Q, T). Any idea why?

Thanks.

Simple your IM is too old. The uppercase percent escapes was a late addition.
For example '%D' was added to IM v6.2.6-2, by my request, for getting animation disposal info.

Actually the other percentages were also added by my request to make extracting geometry info in the form of geometry argument easier.

Makes sense. Thanks for the info.
