Or

final Path binary = Paths.get("/usr/bin/gm");
final GraphicsMagick gm = new GraphicsMagick(binary);

Note that the empty constructor will use the default installation path of GraphicsMagick in Linux (/usr/bin/gm). If you wish to use another binary please use the path constructor with the proper binary. e.g. C:\Program Files\GraphicsMagick\gm.exe

After initialization, you can use GraphicsMagick sub-commands.

Note that currently only convert sub-command is supported.
