lEdgeCoeff

The edge enhancement coefficient. This value will be internally divided by 100. Set this parameter to MSE_DEFAULT to use the default values (which is 170 interpreted as 1.7). This option will be used only if MSE_EDGEENH is set in lFlags. Any value (>= 0) is valid. A value of 100 will be interpreted as 1.0 and will keep the bitmap’s edges un-enhanced. Larger values will produce more visible edges. Smaller values will produce less visible edges. Practically, the enhancement levels out at 200000 (interpreted as 2000.0) – values bigger than that will not enhance the bitmap’s edges any more.
