Erodes dark objects in the class object's bitmap by the specified amount.
#include "ltwrappr.h"
virtual L_INT LBitmap::MaxFilter(uDim=3, uFlags = 0)
Dimensions of the neighborhood used for filtering (uDim x uDim), in pixels.
Reserved for future use. Must be 0.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
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.
