GaussianFilter method (ILEADRasterProcess)

Visual Basic example

Visual C++ 5.0 example

 

Syntax

short GaussianFilter(ILEADRaster *pRaster, short iRadius);

Overview

Refer to Removing Noise.

Remarks

Smoothes or blurs an image by applying a Gaussian filter to the specified bitmap.

Each pixel in the bitmap is blurred based on neighborhood pixels. The parameter iRadius determines the size of the neighborhood to consider when blurring a pixel. The result is a blurred version of the original image.

This method supports 12 and 16-bit grayscale images and 48 and 64-bit color images. Support for 12 and 16-bit grayscale images and 48 and 64-bit color images is available only in the Document/Medical toolkits.

This method 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 method.
