ConvolutionKernel

Returns a predefined pixmap convolution kernel.

Syntax

• ConvolutionKernel(s)

  • s is a string

Description

ConvolutionKernel(s) returns the predefined pixmap convolution kernel named s.

The following kernel names are recognised:

• 3×3 box blur

• 3×3 edge detector 1

• 3×3 edge detector 2

• 3×3 edge detector 3

• 3×3 edge detector 4

• 3×3 edge detector 5

• 3×3 emboss

• 3×3 Gaussian blur

• 3×3 identity

• 3×3 sharpen

• 3×3 Sobel 1

• 3×3 Sobel 2

• 5×5 box blur

• 5×5 Gaussian blur

• 5×5 unsharp masking

Examples

convolve(ExampleData("Sally"), ConvolutionKernel("5×5 Gaussian blur"))

convolve(ExampleData("Sally"), ConvolutionKernel("3×3 sharpen"))

convolve(ExampleData("Sally"), ConvolutionKernel("3×3 emboss"))

convolve(ExampleData("Sally"), ConvolutionKernel("3×3 Sobel 1") + ConvolutionKernel("3×3 Sobel 2"))
