public static boolean outputOccupiedRanges(Raster raster,
RasterRangesUtils.RangesOutput out)
raster - image to be segmented in non black or non-transparent rangesout - destination of the non null ranges
public static boolean outputOccupiedRangesOfBinaryPixels(byte[] binaryBits,
int w,
int h,
RasterRangesUtils.RangesOutput out)
binaryBits - byte-packed binary bits of an imagew - width of the image (in pixels)h - height of the imageout -
public static boolean outputOccupiedRanges(int[] pixels,
int w,
int h,
int occupationMask,
RasterRangesUtils.RangesOutput out)
pixels - integer values of the pixels of an imagew - width of the image (in pixels)h - height of the imageoccupationMask - mask used to select which bits are used in a pixel to check its occupied status. 0xff000000 would only take the alpha layer into account, for instance.out - where to output all the contiguous ranges of non occupied pixels
