SyntaxThe RotateBicubic type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | RotateBicubic(Double) |
Initializes a new instance of the RotateBicubic class.
|
| RotateBicubic(Double, Boolean) |
Initializes a new instance of the RotateBicubic class.
|
Properties| Name | Description | |
|---|---|---|
 | Angle |
Rotation angle, [0, 360].
(Inherited from BaseRotateFilter.) |
| FillColor |
Fill color.
(Inherited from BaseRotateFilter.) |
| FormatTranslations |
Format translations dictionary.
(Overrides BaseTransformationFilterFormatTranslations.) |
| KeepSize |
Keep image size or not.
(Inherited from BaseRotateFilter.) |
Methods| Name | Description | |
|---|---|---|
| Apply(Bitmap) |
Apply filter to an image.
(Inherited from BaseTransformationFilter.) |
| Apply(BitmapData) |
Apply filter to an image.
(Inherited from BaseTransformationFilter.) |
| Apply(UnmanagedImage) |
Apply filter to an image in unmanaged memory.
(Inherited from BaseTransformationFilter.) |
| Apply(UnmanagedImage, UnmanagedImage) |
Apply filter to an image in unmanaged memory.
(Inherited from BaseTransformationFilter.) |
 | CalculateNewImageSize |
Calculates new image size.
(Inherited from BaseRotateFilter.) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ProcessFilter |
Process the filter on the specified image.
(Overrides BaseTransformationFilterProcessFilter(UnmanagedImage, UnmanagedImage).) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
Fields| Name | Description | |
|---|---|---|
 | angle |
Rotation angle.
(Inherited from BaseRotateFilter.) |
| fillColor |
Fill color.
(Inherited from BaseRotateFilter.) |
| keepSize |
Keep image size or not.
(Inherited from BaseRotateFilter.) |
Extension Methods| Name | Description | |
|---|---|---|
 | HasMethod |
Checks whether an object implements a method with the given name.
(Defined by ExtensionMethods.) |
| IsEqual |
Compares two objects for equality, performing an elementwise
comparison if the elements are vectors or matrices.
(Defined by Matrix.) |
| To(Type) | Overloaded.
Converts an object into another type, irrespective of whether
the conversion can be done at compile time or not. This can be
used to convert generic types to numeric types during runtime.
(Defined by ExtensionMethods.) |
| ToT | Overloaded.
Converts an object into another type, irrespective of whether
the conversion can be done at compile time or not. This can be
used to convert generic types to numeric types during runtime.
(Defined by ExtensionMethods.) |
RemarksThe class implements image rotation filter using bicubic interpolation algorithm. It uses bicubic kernel W(x) as described on Wikipedia (coefficient a is set to -0.5).
 Note |
|---|
| Rotation is performed in counterclockwise direction. |
The filter accepts 8 bpp grayscale images and 24 bpp color images for processing.
Sample usage:
// create filter - rotate for 30 degrees keeping original image size RotateBicubic filter = new RotateBicubic( 30, true ); // apply the filter Bitmap newImage = filter.Apply( image );
Initial image:
