org.im4java.core.CommandException: org.im4java.core.CommandException: magick: no images found for operation

I m trying to compare two images located under my OS machine and i m using this method:

Code: Select all

	public boolean compareImages (String expectedScreenShot, String capturedScreenShot, String pdiffCompare) {
		ProcessStarter.setGlobalSearchPath("/usr/local/bin/");
		CompareCmd compare = new CompareCmd();
		// For metric-output
		IMOperation cmpOp = new IMOperation();
		// Set the compare metric
		cmpOp.metric("AE");
		// Add the expected image
		cmpOp.addImage(expectedScreenShot);
		// Add the current image
		cmpOp.addImage(capturedScreenShot);
		// This stores the difference
		cmpOp.addImage(pdiffCompare);
		try {
			// Do the compare
			compare.run(cmpOp);
			compare.getErrorText();
			return true;
		}
		catch (Exception ex) {
			return false;
		}
	}

im using im4java:1.4.0 but when i run compare.run(cmpOp); i m receiving this exception:

org.im4java.core.CommandException: org.im4java.core.CommandException: magick: no images found for operation `-metric' at CLI arg 1 @ error/operation.c/CLIOption/5225.

any help would be appreciated

Please always provide your IM version and platform. If using IM 7, the syntax for "compare" has changed to "magick compare". Perhaps that is your problem. Also have you checked your metric variable to be sure it has one of the accepted values?
