Dilate

Dilate expands every pixel of your terrain or mask using the selected kernel or shape.

• Size Sets the distance or radius of dilation. Larger values expand farther.

• Shape Defines the overall shape of the dilation operation (e.g. circle, square).

• Iterations Number of times to repeat the dilation. Higher values make the effect stronger or thicker.

• Kernel Structuring element shape controlling the dilation pattern:

  • Cross: 4-connected cross-shaped kernel, good for plus-sign expansion.

  • Rectangle: Expands evenly in all directions with a rectangular pattern.

  • Line: Horizontal line kernel, expands only sideways.

  • LineVertical: Vertical line kernel, expands only vertically.

• Invert Inverts the input before dilation, effectively shrinking bright regions instead of expanding them.
