ContourPyr

DESCRIPTION

This module creates contours on a 2-layer pyramid.

INPUTS

Port: Pyramid In
Type: Pyramid
Constraints: 2-layer
Constraints: 1..-baseLat
Constraints: 1..3-D compression
Constraints: unique..multiple-compression type
The input pyramid to be contoured.

Port: Colormap
Type: Lattice
Optional: This port is optional.
Constraints: 1-D
Constraints: 4-vector
Colormap to be used to color the contours. If no colormap is present, a default colormap is used.

WIDGETS

Port: Number of Contours
Type: Slider
The number of contour levels.

Port: Channel
Type: Slider
If the pyramid base lattice contains vector data, this selects the vector component.

Port: Min Contour
Type: Dial
The minimum contour level.

Port: Max Contour
Type: Dial
The maximum contour level.

Port: Line Width
Type: Slider
The width of the contour line in pixels.

OUTPUTS

Port: Contours
Type: Geometry
The contour lines.

KNOWN PROBLEMS

The output geometry may exhaust shared memory for very large pyramids.
