Usage in object oriented programming languages

Java

// init CLIJ and GPU
import net.haesleinhuepf.clij2.CLIJ2;
import net.haesleinhuepf.clij.clearcl.ClearCLBuffer;
CLIJ2 clij2 = CLIJ2.getInstance();

// get input parameters
ClearCLBuffer pointlist = clij2.push(pointlistImagePlus);
spots_destination = clij2.create(pointlist);

// Execute operation on GPU
clij2.pointlistToLabelledSpots(pointlist, spots_destination);

// show result
spots_destinationImagePlus = clij2.pull(spots_destination);
spots_destinationImagePlus.show();

// cleanup memory on GPU
clij2.release(pointlist);
clij2.release(spots_destination);

Matlab

% init CLIJ and GPU
clij2 = init_clatlab();

% get input parameters
pointlist = clij2.pushMat(pointlist_matrix);
spots_destination = clij2.create(pointlist);

% Execute operation on GPU
clij2.pointlistToLabelledSpots(pointlist, spots_destination);

% show result
spots_destination = clij2.pullMat(spots_destination)

% cleanup memory on GPU
clij2.release(pointlist);
clij2.release(spots_destination);

Icy JavaScript

// init CLIJ and GPU
importClass(net.haesleinhuepf.clicy.CLICY);
importClass(Packages.icy.main.Icy);

clij2 = CLICY.getInstance();

// get input parameters
pointlist_sequence = getSequence();
pointlist = clij2.pushSequence(pointlist_sequence);
spots_destination = clij2.create(pointlist);

// Execute operation on GPU
clij2.pointlistToLabelledSpots(pointlist, spots_destination);

// show result
spots_destination_sequence = clij2.pullSequence(spots_destination)
Icy.addSequence(spots_destination_sequence);
// cleanup memory on GPU
clij2.release(pointlist);
clij2.release(spots_destination);
