Problem with ColorProcessor method

[Ned Horning]

Hi - I am writing a plugin that uses the ColorProcessor.getChannel()
method. When I run the plugin in Eclipse it works just fine but when I
run it in Fiji or ImageJ by placing the .jar file in the appropriate
plugins directory I get the following error:

java.lang.NoSuchMethodError: ij.process.ColorProcessor.getChannel(I)[B

The "[B" at the end are in the Exception window and I have no idea what
that means. The line of code where the problem occurs is:

byte[] array1 = image.getChannel(chanA);

image is a ColorProcessor and chanA is an int. I import ij.process.* at
the top of the plugin.

Can anyone make sense out of what I'm doing wrong?

Thanks in advance for any help.

Ned

Hi Ned,

Did you verify that your Fiji/ImageJ installation is the same (or newer)
version of ImageJ as your Eclipse ImageJ dependency? Click the ImageJ
status bar to see the version number. If your Fiji/ImageJ version is older,
try updating the ij.jar to a newer version first (Help > Update ImageJ).

Curtis

Thanks Curtis - updating ij.jar did the trick.
