int value,

RasterColor fillColor,
BendCommandFlags flags
)
value
Amount of stretching, where positive values stretch the pixels toward the edges, and negative values stretch the pixels toward the center. Possible values are range in between -500 and 500.
centerPoint
Contains the center of the arc. This is ignored when either BendCommandFlags.Horizontal or BendCommandFlags.Vertical is set in the flags parameter.
fillColor
Specifies the fill color for any exposed areas.
flags
Flags that indicate how to handle peripherally exposed areas, how to handle centrally exposed areas and the type of bending. You can use a bitwise OR ( ¦ ) to specify one flag from each group.
Run the BendCommand on an image.
