Hi Avital,
the int mOption comes from the Measurements interface. The constants are
defined in the source below. You can add them to get what you want, e.g. if
you call ImagePlus#getStatistics() without arguments it actually calls
getStatistics( AREA+MEAN+MODE+MIN_MAX).
package ij.measure;
public interface Measurements {
public static final int AREA=1,MEAN=2,STD_DEV=4,MODE=8,MIN_MAX=16,
CENTROID=32,CENTER_OF_MASS=64,PERIMETER=128, LIMIT=256, RECT=512,
LABELS=1024,ELLIPSE=2048,INVERT_Y=4096,CIRCULARITY=8192,
SHAPE_DESCRIPTORS=8192,FERET=16384,INTEGRATED_DENSITY=0x8000,
MEDIAN=0x10000, SKEWNESS=0x20000, KURTOSIS=0x40000, AREA_FRACTION=0x80000,
SLICE=0x100000, STACK_POSITION=0x100000, SCIENTIFIC_NOTATION=0x200000,
ADD_TO_OVERLAY=0x400000, NaN_EMPTY_CELLS=0x800000;
/** Maximum number of calibration standard (20) */
public static final int MAX_STANDARDS = 20;
}
