ImageWarp Class |
Namespace: Accord.Imaging.Filters
The ImageWarp type exposes the following members.
Name | Description | |
---|---|---|
FormatTranslations |
Format translations dictionary.
(Overrides BaseFilterFormatTranslations.) | |
WarpMap |
Map used for warping images.
|
Name | Description | |
---|---|---|
Apply(Bitmap) |
Apply filter to an image.
(Inherited from BaseFilter.) | |
Apply(BitmapData) |
Apply filter to an image.
(Inherited from BaseFilter.) | |
Apply(UnmanagedImage) |
Apply filter to an image in unmanaged memory.
(Inherited from BaseFilter.) | |
Apply(UnmanagedImage, UnmanagedImage) |
Apply filter to an image in unmanaged memory.
(Inherited from BaseFilter.) | |
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 BaseFilterProcessFilter(UnmanagedImage, UnmanagedImage).) | |
ToString | Returns a string that represents the current object. (Inherited from Object.) |
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.

The image processing filter implements a warping filter, which sets pixels in destination image to values from source image taken with specified offset (see WarpMap).
The filter accepts 8 bpp grayscale images and 24/32 color images for processing.
Sample usage:
// build warp map int width = image.Width; int height = image.Height; IntPoint[,] warpMap = new IntPoint[height, width]; int size = 8; int maxOffset = -size + 1; for ( int y = 0; y < height; y++ ) { for ( int x = 0; x < width; x++ ) { int dx = ( x / size ) * size - x; int dy = ( y / size ) * size - y; if ( dx + dy <= maxOffset ) { dx = ( x / size + 1 ) * size - 1 - x; } warpMap[y, x] = new IntPoint( dx, dy ); } } // create filter ImageWarp filter = new ImageWarp( warpMap ); // apply the filter Bitmap newImage = filter.Apply( image );
