Parameter |
Description |

uDim |
Dimensions of the neighborhood used for filtering (uDim x uDim), in pixels. |

Comments
This is a more controlled version of the omni-directional dilation filter that you can set with the LBitmap::BinaryFilter function.
The effect can be controlled by specifying the size of the neighborhood that is used for calculating each pixel value. For example, for 8x8, pass 8 in the uDim parameter. Each pixel is replaced with the minimum value of its neighborhood.
This function can process the whole image or a region of the image.
This function supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
This function does not support signed data images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this function.
