Hi,
Can someone give me an advice how to run groovy script from another application (standalone Java, not a plugin) using Image API? The script attached below runs perfectly when executed from script editor within Fiji, but fails when run from external code.
I am trying to run this script:
// Exemplary script: script.groovy
//#@String(label="path") path
import ij.IJ
import ij.ImagePlus
import ij.process.ImageProcessor
import ij.process.ShortProcessor
println IJ.getFullVersion()
curr = IJ.openImage(path)
println "Opened file ${curr}"
stack = curr.getStack()
ImageProcessor ip = stack.getProcessor(1)
ip.setAutoThreshold("Default") // not relevant for this example
ip.setThreshold(0.0, 5, 0) // not relevant for this example
mask = ip.createMask()
IJ.save(new ImagePlus("out", mask), "/tmp/out.tif")
from program:
// Script runner
import java.io.File;
import java.io.FileNotFoundException;
import javax.script.ScriptException;
import org.scijava.script.ScriptService;
import net.imagej.ImageJ;
public class Run {
public static void main(String[] args) throws ScriptException, FileNotFoundException {
final ImageJ ij = new ImageJ();
// ij.ui().showUI();
ScriptService script = ij.script();
script.run(new File("/tmp/script.groovy"), // call the script above
false, "path", "/tmp/Zstack_raw_deskew_c1_t46.tif");
}
}
but I get error like this:
groovy.lang.MissingMethodException: No signature of method: ij.process.ShortProcessor.createMask() is applicable for argument types: () values: []
Possible solutions: createImage(), createImage(), getMask(), setMask(ij.process.ImageProcessor)
at org.codehaus.groovy.runtime.ScriptBytecodeAdapter.unwrap(ScriptBytecodeAdapter.java:70)
at org.codehaus.groovy.runtime.callsite.PojoMetaClassSite.call(PojoMetaClassSite.java:46)
... (truncated)
Another question is if it is possible to pass ImagePlus reference to the script as a parameter, but again, from standalone application.
Thanks
