Description

uDim

Comments

This is a more controlled version of the omni-directional erosion 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 maximum 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 32-bit grayscale images. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this function.
