A raster kernel-based filter.


The RasterConvolutionFitler object is a kernel based raster filter. There are several predefined kernels available, and you can also implement your own kernels to filter the raster.

RasterConvolutionFitler supports two convolution filter-specific interfaces, IStockConvolutionFilter and IRasterConvolutionFilter. IStockConvolutionFilter is used to select one of predefined, well-known convolution filters, such as horizontal and vertical line detection, 3x3 and 5x5 Laplacian filters, and etc. IRasterConvolutionFilter is used to set up custom kernel with kernel coefficients. A constant gain factor can be added to both stock or custom convolution filters.

Supported Platforms

Windows, Solaris, Linux


Interfaces Description
IPixelFilter Provides access to members that control a pixel filter.
IRasterConvolutionFilter Provides access to members that control a raster kernel-based filter.
IStockConvolutionFilter Provides access to members that control a kernel-based stock filter.
