The851              default is -1: all matches are returned. Applicable in852              findItemsByBitmap.853      allowOverlap (boolean, optional):854              allow returned icons to overlap. If False, returned list855              contains only non-overlapping bounding boxes. The856              default is False.857      scale (float or pair of floats, optional):858              scale to be applied to the bitmap before859              matching. Single float is a factor for both X and Y860              axis, pair of floats is (xScale, yScale). The default is861              1.0.862      bitmapPixelSize (integer, optional):863              size of pixel rectangle on bitmap for which there must864              be same color on corresponding screenshot rectangle.  If865              scale is 1.0, default is 1 (rectangle is 1x1). If scale866              != 1.0, the default is 2 (rectangle is 2x2).867      screenshotPixelSize (integer, optional):868              size of pixel rectangle on screenshot in which there869              must be a same color pixel as in the corresponding870              rectangle on bitmap. The default is scale *871              bitmapPixelSize.872      preprocess (string, optional):873              preprocess parameters that are executed to both screenshot874              and reference bitmap before running findBitmap. By default875              there is no preprocessing.876              Example: d.verifyBitmap("ref.png", preprocess="-threshold 60%")877              will execute two imagemagick commands:878                1. convert screenshot.png -threshold 60% screenshot-pp.png879                2. convert ref.png -threshold 60% ref-pp.png880              and then search for ref-pp.png in screenshot-pp.png.
