edgeMode - SVG: Scalable Vector Graphics 编辑

The edgeMode attribute 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.

Two elements are using this attribute: <feConvolveMatrix> and <feGaussianBlur>

feConvolveMatrix

For <feConvolveMatrix>, edgeMode 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.

duplicate

This value 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.

wrap

This value indicates that the input image is extended by taking the color values from the opposite edge of the image.

none

This value indicates that the input image is extended with pixel values of zero for R, G, B and A.

feGaussianBlur

For <feGaussianBlur>, edgeMode 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.

duplicate

This value 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.

wrap

This value indicates that the input image is extended by taking the color values from the opposite edge of the image.

none

This value indicates that the input image is extended with pixel values of zero for R, G, B and A.
