Using the FadedMask Method
When using the FadedMaskCommand class, the general process is as follows:
-
Open any bitmap.
-
Select any region.
-
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);

FadedMaskCommandFlags.FillWithDumpColor | FadedMaskCommandFlags.FadeWhiteToBlack
FadedMaskCommandFlags.FillWithDumpColor | FadedMaskCommandFlags.DumpColorStart
FadedMaskCommandFlags.FillWithDumpColor | FadedMaskCommandFlags.DumpColorStart | FadedMaskCommandFlags.FadeWhiteToBlack
FadedMaskCommandFlags.FillWithDumpColor | FadedMaskCommandFlags.NoTransparencyFill
FadedMaskCommandFlags.FillWithDumpColor | FadedMaskCommandFlags.NoTransparencyFill | FadedMaskCommandFlags.TransparencyAsDump
plus many other possibilities
Second
Using FadedMaskCommandFlags.FadeOutsideRegion:
Region type

FadedMaskCommandFlags.FadeOutsideRegion
FadedMaskCommandFlags.FadeOutsideRegion | FadedMaskCommandFlags.FadeWhiteToBlack
FadedMaskCommandFlags.FadeOutsideRegion | FadedMaskCommandFlags.FillWithDumpColor
FadedMaskCommandFlags.FadeOutsideRegion | FadedMaskCommandFlags.FillWithDumpColor | FadedMaskCommandFlags.FadeWhiteToBlack
