21  // The dilate, erode, and dilateErode methods all have identical
22  // signatures. The source, dest, and temp_dest are all the same
23  // size, namely w x h. The result will be written to dest, while
24  // temp_dest is basically just a temporary work buffer. It is
25  // only needed if both of the sizes are greater than 1. Due to the
26  // nature of the algorithm employed, the first size/2, and up to
27  // the last 3*size/2 pixels are not written to. The region of
28  // interest should therefore be embedded in a larger region to
29  // ensure that all data of interest is written to.
30  //
31  // xsize and ysize must be odd, and in the case of dilate and erode,
32  // positive. When calling dilateErode, it is the sign of the two
33  // sizes which determines whether a dilate or erode occurs. Positive
34  // values are dilates, negative are erodes.
