public enum MatrixEdgeMode
extends Enum<MatrixEdgeMode>

Enumeration of SVG (Scalable Vector Graphics) filter effect 'feConvolveMatrix' edgeMode types.

"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' 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.

 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 ... Nm NM
 Extended by two pixels using 'duplicate':
  11 11   11 12 ... 1m 1M   1M 1M
  11 11   11 12 ... 1m 1M   1M 1M
  11 11   11 12 ... 1m 1M   1M 1M
  21 21   21 22 ... 2m 2M   2M 2M
  .. ..   .. .. ... .. ..   .. ..
  n1 n1   n1 n2 ... nm nM   nM nM
  N1 N1   N1 N2 ... Nm NM   NM NM
  N1 N1   N1 N2 ... Nm NM   NM NM
  N1 N1   N1 N2 ... Nm NM   NM NM
 

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

Extended by two pixels using 'wrap':
  nm nM   n1 n2 ... nm nM   n1 n2
  Nm NM   N1 N2 ... Nm NM   N1 N2
  1m 1M   11 12 ... 1m 1M   11 12
  2m 2M   21 22 ... 2m 2M   21 22
  .. ..   .. .. ... .. ..   .. ..
  nm nM   n1 n2 ... nm nM   n1 n2
  Nm NM   N1 N2 ... Nm NM   N1 N2
  1m 1M   11 12 ... 1m 1M   11 12
  2m 2M   21 22 ... 2m 2M   21 22
 

'none' indicates that the input image is extended with pixel values of zero for R, G, B and A."

none

public static final MatrixEdgeMode none

Method Detail

values

public static MatrixEdgeMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (MatrixEdgeMode c : MatrixEdgeMode.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static MatrixEdgeMode valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
