Initializes a new
BendCommand class object with explicit parameters.
Syntax
Parameters
- 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.
Example
Run the BendCommand on an image.
