in thread substr in nested foreach loop

Yeah but no but yeah.

If you stick a warning before each substr operation giving the length of the string and which characters it's trying to find, I bet you'll trace the problem pretty quickly.

    Jasper: Yeah, I got it. *sheepish grin* End of line char at the end of file. Thanks. :)

    Oh, and a couple of places where the file formatting was irregualr because of overwriting. *feels dumb*

    On the positive side, I've learnt more in the time it took me to read this thread and attempt to implement all of the suggestions (I did) than I did while trying to debug all by myself...So I owe all the Monks who were kind enough to reply a huge thanks.

[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.
