in reply to Recursive image processing (with ImageMagic)

Irfanview should do what you want already.

i_view32.exe c:\*.png /gray /convert=d:\temp\*.png

I don't see an obvious option for recursive directories, but the directory diving can be done with a very small script that makes the calls to convert everything in the directory.

    I know Irfanview well, but have never tried it on the command line. Within the Windows UI, attempting to wildcard the folders chokes the app. I assume there's a hardcoded practical batch limit in there somewhere. Better to use something like Perl to discover the PNG files one-on-one, process and move on to the next.

[dazz]: Hi I have grabbed an image from an IP camera with Image::Grab. I then want to pass that image object to a subroutine where I do a read-only test on the image with Image:Magick.
[dazz]: How do I pass an image object to a subroutine and then apply a Image::Magick a read-only method to the image object???
[dazz]: Also, I want to use Image::Magick to annotate and composite (not in a sub). How do I take a Image::Grab object and apply Image::Magick write methods to it??
[dazz]: At present, I am saving the Image::Grab image to disk, then creating a new Image::Magick object that reads the disk file.
