Sheets is an OS X widget that automates the process of building sprite sheets from image sequences. Using ImageMagick, animations can be output in strips, sheets, or with custom settings for scale and tiling. File sheets (contact sheets) can also be generated, with file name and original size clearly labeled under each thumbnail. Large collections are automatically paginated when necessary.
Images can be a collection (select multiple files in Finder, then click-drag while opening up Dashboard, and releasing within the drop area), or a single image from a numerical series (Sheets will automatically gather the rest of the images for the sequence). While groups of files can contain any number of files and various file names, images are sorted lexicographically – full serial numbers are required for best results (
0100 will sort correctly, while
100 will not).
When scaling images to fit within specific dimensions, the scaling algorithm can be selected in the preferences side of the widget. For more information on scaling algorithms, there are some great articles posted by imagemagick.org and Bart van der Wolf.
Also new are the alpha output options – transparent (premultiplied), flattened (removed), extracted (alpha only), and multiple files, which produces transparent, RGB, and A files for use in other tools that require straight RGB input (for example, ImageMagick doesn’t support straight RGB in the TIF format, so multiple files are the only way to retain all RGB data).
The output filename is taken from the first image in the series, replacing the frame number with a title set in the preferences. For example, a group of images starting with
animation_ver1_0000.png by default will result in
File sheets are slightly different, in that they prepend the user-set title to the beginning of the first file name. By default, a collection of files starting with
animation_ver1_0000.png results in

However, the author(s) assume absolutely no liability, and the software is offered with no warranty or quality assurance. And God forbid you use it in the operation of nuclear facilities (a warning I see in the EULA of so many applications, I really do wonder how exactly someone could use a graphics utility in the operation of a power plant). In short, use at your own risk.
This widget requires ImageMagick to run, please see imagemagick.org for details. You can download the installer directly, or download and install via MacPorts. The install location (needed for Sheets to access the commands) is typically
Alternatively, you could also follow directions from Mat Schaffer (places the commands in
/user/local/bin/ but does not include some file formats) or use the install script by Master Kain (locates the commands in
/user/local/bin/ and installs several other support scripts as well).
When it comes time to update, it’s often easiest if you’ve installed via MacPorts; simply run the auto update command, and the rest is taken care of for you. Because of this, MacPorts is the recommended installation mechanism. Though it’ll take a wee bit of command line work to get going, it’ll pay off in the long run.
Double check the installation by typing in a sample command, and confirm the install location by typing in
which montage. Once verified, update the widget information with the correct command location and click “done” to save the preferences.

Yes, if i run
which montage in the terminal it returns /opt/local/bin/montage. The Dashboard Sheets application setting is set to /opt/local/bin/ but still wont work. Any particular reason? It used to work perfectly on my Leopard Installation.
Thanks for your time.
PD: Im running Snow Leopard. Running
Magick-config --version returns 6.5.8 Q16
Fixed it!. I still don’t know the reason but, I ran
sudo port uninstall ImageMagick after that i deleted the complete tar file i downloaded from the ImageMagick site and the decompressed version in /usr/local/bin. After doing that I tested ImageMagick to see it was uninstalled with
which convert and
which montage. After that i installed ImageMagick with
sudo port install ImageMagick and verified that the Sheets settings path was /opt/local/bin/. After that it worked. After it worked i think that one reason that caused confusion on me was if the path should end with /bin/ or /bin.
PD: I have to say it again. Its a great tool I use for my game development every day ! Its working WIPPIIIIIII!
It doesn’t seem to be working on my Snow Leopard installation. Any suggestions?. I installed imageMagick using macports and manually but it didn’t help either way. Thanks in advance. BTW Great tools
