Questions tagged [im4java]

The library im4java provides a pure-java interface to ImageMagick, GraphicsMagick and other popular commandline tools like jpegtran, ufraw, dcraw, exiftool. The im4java-engine permits the addition of new tools in a very short time (less than an hour)

The basic architecture of im4java is quite simple. It boils down to calling all underlying tools simply by using a ProcessBuilder-object. All the magic of im4java ist to hide the complexities. If you have just one simple call of an external tool in your program, you might be better of by hardcoding the ProcessBuilder-call yourself. If you don't need the simplicity or the advanced features of the im4java-library, your code will certainly be faster and more efficient.
