Meziantou.FrameworkIPixelNeighborhoodOperation<TPixel> Interface
A custom image processor that computes each row from the unmodified pixels of the frame (a neighborhood filter, such as a blur or an edge detector), applied to every frame of an image by ImageProcessingExtensions.ApplyNeighborhoodOperation.
public interface IPixelNeighborhoodOperation<TPixel> where TPixel : unmanagedType parameters
TPixel- The pixel type of the rows: the pixel type of the image, or a wider working type.
Remarks
Implement the operation as a struct: the processing loop is then compiled for it, without an interface call per row. IPixelNeighborhoodOperation<TPixel>.Invoke is called from several threads at once when ImageConfiguration.MaxDegreeOfParallelism is greater than 1, for different rows of the same instance: it must not change the state of the operation.
Methods
| Name | Description |
|---|---|
| Invoke(int, PixelRowSource<TPixel>, Span<TPixel>) | Computes one row. |
Invoke(int, PixelRowSource<TPixel>, Span<TPixel>)
Computes one row.
void Invoke(int y, PixelRowSource<TPixel> source, Span<TPixel> destination)Parameters
yint- The index of the row in the frame.
sourcePixelRowSource<TPixel>- The pixels of the frame before the operation, in rows. Valid until the method returns.
destinationSpan<TPixel>- The row to write. Its initial content is unspecified: write every pixel. Valid until the method returns.
