JMagick - setMonochrome()

[Christoph Burschka]

Has anyone here used the JNI interface for ImageMagick (JMagick)?

Unfortunately, I'm finding it really hard to work with because of the
sparse documentation. The only help I've found is a FAQ that touches on
6 usage-related topics; the generated Javadoc consists of uncommented
method heads. Those few methods that do have Javadoc comments are
explained by enlightening descriptions like this one:

void setVerbose(int value) - Set the verbose attribute.

----

Specifically, what I'm looking for is a description of

void ImageInfo.setMonochrome(int value)

Since the equivalent command line option in ImageMagick, "-monochrome",
takes no arguments, I thought that the value might be a boolean in
disguise (and would activate monochrome mode on >0, normal mode
otherwise). That didn't work though. Anyone have an idea what values
this method can take and what it does?

Just in case there is no other follow-up, let me add that I have since
given up on JMagick entirely and use Runtime.exec() now. More stable,
faster, better documented - and it even works on both Windows and Unix.
