edgeMode property

Determines how to extend the input image as necessary with color values so that the matrix operations can be applied when the kernel is positioned at or near the edge of the input image.

This property is read-only.

Type: SVGAnimatedEnumeration

One of the following three values:

duplicate duplicate	Indicates that the input image is extended along each of its borders as necessary by duplicating the color values at the given edge of the input image: Copy Original N-by-M image, where m=M-1 and n=N-1: 11 12 ... 1m 1M 21 22 ... 2m 2M .. .. ... .. .. n1 n2 ... nm nM N1 N2 ...

Remarks

One of three values that determines how to extend the input image as necessary with color values so that the matrix operations can be applied when the kernel is positioned at or near the edge of the input image.

If attribute edgeMode is not specified, then the effect is as if a value of duplicate were specified.
