Field Details

EDGE_ZERO_FILL

public static final int EDGE_ZERO_FILL

Alias for ConvolveOp.EDGE_ZERO_FILL.

See Also:

• EDGE_REFLECT
• Constant Field Values

EDGE_NO_OP

public static final int EDGE_NO_OP

Alias for ConvolveOp.EDGE_NO_OP.

See Also:

• EDGE_REFLECT
• Constant Field Values

EDGE_REFLECT

public static final int EDGE_REFLECT

Adds a border to the image while convolving. The border will reflect the edges of the original image. This is usually a good default. Note that while this mode typically provides better quality than the standard modes EDGE_ZERO_FILL and EDGE_NO_OP, it does so at the expense of higher memory consumption and considerable more computation.

See Also:

• Constant Field Values

EDGE_WRAP

public static final int EDGE_WRAP

Adds a border to the image while convolving. The border will wrap the edges of the original image. This is usually the best choice for tiles. Note that while this mode typically provides better quality than the standard modes EDGE_ZERO_FILL and EDGE_NO_OP, it does so at the expense of higher memory consumption and considerable more computation.
