imagemagik ----> convert ??
I have this package installed (ImageMagick-6.2.3-4.2) but when I try to run imagemagik I get the "command not found" error. Using pin on the installed package I found the command convert and used that as follows: convert -resize 640x480 oldname.jpg newname.jpg I guess I'll need to write a small script as it will not allow wildcards. -- Ken Schneider UNIX since 1989, linux since 1994, SuSE since 1998

Hi Ken, Like sox for audio, ImageMagick is a collection of discreet, specialized image processing commands bundled together into a package. I haven't used it in a while for batch processing (I think I created several sets of thumbnails, once) but I don't think I had to write a script. Have you been here?: /usr/share/doc/packages/ImageMagick/index.html regards, Carl
I suggest you have a look at this article Graphics from the command line Flip, size, rotate, and more with ImageMagick http://www-128.ibm.com/developerworks/linux/library/l-graf/ -- Regards, Graham Smith

Yes, it does; read the man: ] To create a visual image directory of all your JPEG images, use: ] ] convert 'vid:*.jpg' directory.miff You just have to quote them so that the shell does not see the wildcards.

I ended up using this: for I in `ls -1 *.JPG`;do convert -resize 640x480 ${I} ${I};echo ${I};done Which worked great, converted about 200 photos in less then a minute. Didn't care about over writing as the originals are on a CD. -- Ken Schneider UNIX since 1989, linux since 1994, SuSE since 1998

And to avoid overwriting would this work? for I in `ls -1 *.JPG`;do convert -resize 640x480 ${I} ${I}.new;echo ${I}.new;done Though I am sure there is a fancier perl way to preserve the extention so the name becomes filespec.new.jpg On that I am still studying perl. -- ___ _ _ _ ____ _ _ _ | | | | [__ | | | |___ |_|_| ___] | \/

Ken, I believe you'll find that running ImageMagick from the shell, you'll use the command "display" instead. Guess they were being kind to us, so we wouldn't have to type the long name out. ;o) Lee

Yes, that got me too when I first began using it. Turns out ImageMagick is the name of a collection of command line image-processing utitlities. It is not a command or a program itself. See a list of the tools that make up ImageMagick here: http://www.imagemagick.org/script/command-line-tools.php I noticed elsewhere on the site that it runs on "all major OSs." I did not know that! I thought it was only for Linux (or at least the Unix family).

Hi everyone. Don't know whether this is helpful but if you're into imaging as we are then gd is a real time saver. Having had to suffer clicking and poking at a crashintosh for so many years it really is a godsend to have a proper batch operating system again. Steve.

Be sure you have imagemagick installed. Two that can do it are convert and mogrify. I have used both with great results.
