Shape Properties and Settings

Each shape that is created or imported appears on a separate line in the top section of the Data Properties and Settings panel. You can control the visibility of a shape within a view with the icons available in the top section of the panel, as well as access settings in the lower section to apply effects to selected visuals. A pop-up menu is available that lets you export shapes in the .ORSObject file format, execute a macro, create and extract a structured grid, as well as modify a region of interest (see Shapes Pop-Up Menu).

All shapes that can be added to scene views are listed in the top section of the Data Properties and Settings panel.

  • Click the Shapes icon at the top of the panel to see the available shapes (see Filters for information about filtering the listed items).
  • Click the Eye icon on the left side of the listed item to show or hide the shape in the current scene. Click the 3D icon on the right side of the listed item to show or hide the shape in the 3D view of the current scene. See Visibility and Color/LUT Controls for more information about changing visibility.
  • Click the color box to change the color of the lines that define a shape.
  • Select a shape to see its basic properties and size and to access settings to modify its appearance.
  • Right-click a shape to access its pop-up menu (see Shapes Pop-Up Menu).

The information available for the selected shape includes its size, area, and volume. These measurements are calculated as pixels*spacing.

Basic properties
Item Description
Boxes Size direction 0, 1, 2… Is the length of each side of the box.
Surface… Is the surface area of the box.
Volume… Is the volume of the box.
Capsules and Cylinders Height… Is the height of the capsule or cylinder.
Radius… Is the radius of the capsule or cylinder.
Surface… Is the surface area of the capsule or cylinder.
Volume… Is the volume of the capsule or cylinder.
Spheres Radius… Is the radius of the sphere.
Surface… Is the surface area of the sphere.
Volume… Is the volume of the sphere.

You can use the Histogram tool that is available in the Tools box to visualize and analyze the distribution of intensity values of image data that intersects with the selected shape (see Plotting Histograms from Shapes).

The Histogram tool is not available for planes.

The properties available for modifying the appearance of shapes are contained in the Shape properties panel, shown below.

If required for a specific workflow, you can set which shape borders and anchors are selectable and can be manipulated. An example of the main code in the Script Runner dialog for setting the state of highlighted table borders is shown below.

Item Description
Density

Lets you control the spacing within the grid that defines capsules, cylinders, and spheres. Applicable to 3D views only.

  • Density can be adjusted with the Density slider.
Thickness Lets you control the thickness of the shape outline in 2D and 3D views and the thickness of the grid that defines capsules, cylinders, and spheres in 3D views.
  • Thickness can be adjusted with the Thickness slider.
Visual effects The Visual effects box contains a list of all the available visuals — image data, regions of interest, multi-ROIs, and meshes — to which selected 3D effects can be applied (see Applying Visual Effects to Clips and Shapes).

Edge contrast effect applied outside a box

The Effects properties box displays the properties of the selected effect and includes controls, such as sliders, menus, and color swatches, that you can use to change its properties. You should note that it is possible to apply shape effects to multiple objects and to corresponding data that is either inside or outside of the shape.

Note The visual effects you create with shapes can be included in animated sequences and in screen captures (see Creating Animated Sequences and Exporting Screenshots).

The Size panel, shown below, indicates the parameters associated with the selected shape as well as controls to automatically align the shape to a selected dataset.

Item Description
Align with dataset

If selected, lets you automatically align the shape along the X, Y, or Z axis of the selected dataset, such as an image, region of interest, or box.

Note Alignments can performed from the center of the shape.
Parameters Indicates the size of the selected shape, such as its height and radius, as well as positions such as its center point.
Note Positions are shown in the world coordinate system.
