AVL.CreateImagePolarTransformMap Method
Creates a spatial map representing an image polar transform.
| Namespace: | AvlNet |
|---|---|
| Assembly: | AVL.NET.dll |
Syntax
public static void CreateImagePolarTransformMap( AvlNet.ImageFormat inImageFormat, AvlNet.Point2D inCenter, AvlNet.PolarSpaceType inSpaceType, AvlNet.InterpolationMethod inInterpolationMethod, out AvlNet.SpatialMap outPolarMap, out AvlNet.Region outOutputRegion )
Parameters
| Name | Type | Range | Default | Description | |
|---|---|---|---|---|---|
 | inImageFormat | AvlNet.ImageFormat | Information about dimensions, depth and pixel type of the image. | ||
| inCenter | AvlNet.Point2D | |||
| inSpaceType | AvlNet.PolarSpaceType | Method of transformation. | ||
| inInterpolationMethod | AvlNet.InterpolationMethod | Bilinear | Interpolation method used in extraction of image pixel values. Default value: Bilinear. | |
 | outPolarMap | AvlNet.SpatialMap | Output spatial map. | ||
| outOutputRegion | AvlNet.Region | Pixels set by the spatial map application |
Description
The operation generates map that describes image transformation to polar or log-polar space. Two modes of pixel interpolation are available, the bilinear filtering being more precise and computationally expensive. Usually creating map and then using RemapImage is faster than ImagePolarTransform. For more information see ImagePolarTransform.
