| Apply(Bitmap) |
Apply filter to an image.
(Inherited from BaseInPlaceFilter.) |
| Apply(BitmapData) |
Apply filter to an image.
(Inherited from BaseInPlaceFilter.) |
| Apply(UnmanagedImage) |
Apply filter to an image in unmanaged memory.
(Inherited from BaseInPlaceFilter.) |
| Apply(UnmanagedImage, UnmanagedImage) |
Apply filter to an image in unmanaged memory.
(Inherited from BaseInPlaceFilter.) |
| ApplyInPlace(Bitmap) |
Apply filter to an image.
(Inherited from BaseInPlaceFilter.) |
| ApplyInPlace(BitmapData) |
Apply filter to an image.
(Inherited from BaseInPlaceFilter.) |
| ApplyInPlace(UnmanagedImage) |
Apply filter to an unmanaged image.
(Inherited from BaseInPlaceFilter.) |
| 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 BaseInPlaceFilterProcessFilter(UnmanagedImage).) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
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 filter highlights points on the image using a given set of points.
The filter accepts 8 bpp grayscale, 24 and 32 bpp color images for processing.
ExamplesSample usage:
// Create a blob contour's instance BlobCounter bc = new BlobCounter(image); // Extract blobs Blob[] blobs = bc.GetObjectsInformation(); bc.ExtractBlobsImage(bmp, blobs[0], true); // Extract blob's edge points List<IntPoint> contour = bc.GetBlobsEdgePoints(blobs[0]); // Create a green, 2 pixel width points marker's instance PointsMarker marker = new PointsMarker(contour, Color.Green, 2); // Apply the filter in a given color image marker.ApplyInPlace(colorBlob);
