Smooths or blurs the class object's bitmap by applying a Gaussian filter to it.
virtual L_INT LBitmap::GaussianFilter (nRadius, uFlags = 0)
Value that indicates the radius of the neighborhood on which the filter is applied.
Reserved for future use. Must be 0.
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
Each pixel in the class object's bitmap is blurred based on neighborhood pixels. The parameter nRadius determines the size of the neighborhood to consider when blurring a pixel. The result is a blurred version of the original image.
The amount of blur is controlled by specifying the size of the neighborhood used for blurring or smoothing. The value of the nRadius parameter determines the size and values of the mask.

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.
