This is the homepage of the ImageCropper tool. ImageCropper helps creating animations by automatic cropping of any sets of images to their common non-transparent rectangular area. This can be done with other graphics tools, but it is frequently a rather tedious and laborious task. ImageCropper does this extremely easily and fast and allows cropping dozens of animations in minutes.
ImageCropper was developed in the course of the creation of content for my isometric game engine, as the cropping of hundreds of animations really became a nuisance after a while.
ImageCropper is written in Java and therefore runs on all platforms for which Java Runtime Enviroments exist (Windows, Linux, MacOSX, ...). It is an Open Source project licensed under the GNU Public License and hosted on SourceForge.
In order to run this tool you need a Java Runtime Environment, at least in version 5. If you have it installed, a simple double click on ImageCropper.jar should start the application. On some systems you might have to open a shell, change to the folder containing ImageCropper.jar and type
java -jar ImageCropper.jar
Use the file open dialogue to multi-select the images containing the single frames of the animation. Multi-selecting works by holding Ctrl (Windows, Linux) or Cmd (Mac) while clicking on the images. The images will be cropped to their common non-transparent rectangular area while they are loaded. You can then optionally process them using the options in the "Combine" menu. Once you are satisfied, use the file save dialogue to save the cropped images to a folder of our choice. The saved images will have the same file names as the original images, so you should chose a folder different from the folder containing the original files.
