Using the FadedMask Method

When using the FadedMaskCommand class, the general process is as follows:

1. Open any bitmap.

2. Select any region.

3. Create a Fade Mask. The images below show various fade masks resulting from the use of various flags. For these images, the following values were also used:
   Region type: rounded rectangle.
   Length = 50;
   FadeRate = 15; StepSize = 3; MaxGray = 255; Transparent = RGB(255, 0, 0);
