Outline

Use the Outline component to identify the outline of a person, pet, hand, clothing, sky, ground, building, skin, or custom depth in an image or video, and apply various images or animation sequences along the contour.

Add the Outline Component

To add a Outline component:

1. Go to the Inspector panel
2. Click the + Add Component button
3. Go to Utility
4. Select Outline

Properties

Property	Description
Object Type	Allows you to change the object the outline is applied to with options for a Human, Pet, Hand, Clothing, Sky, Ground, Building, Skin, or Custom Depth. If Depth Bottom is selected, you'll have options for: Depth Bottom: Adjusts the minimum distance from the camera at which the depth algorithm starts detection. A larger value means it detects objects farther away. Depth Threshold: Refers to the depth algorithm's "tolerance" for depth information. A higher value results in smoother contours (fewer jagged edges).
Line Type	Allows you to change the line type. Choose between Line (solid line) and Dot (dotted line).
Brush Type	Allows you to change the brush type to Solid, Chalk, or Crayon.
Brush Size	Controls the dimensions of the line along the contour. Adjusting the size can create variations in the appearance and prominence of the applied line. The default is 15.
Range	Controls the range of the line. The default is (0, 360).
Start Color	Enables you to tint the selected lines with a specific color, allowing for creative customization and visual effects.
End Color	Enables you to tint the selected lines with a specific color, allowing for creative customization and visual effects.
Gradient Type	Allows you to change the gradient type to Loop or Endpoint. Loop: When you set two gradient colors, the transition will be smooth in loop mode, avoiding a harsh shift between colors. Endpoint: Makes the transition abrupt. Colors switch sharply at the intersection point without blending.
Speed	Adjusts the speed at which the lines Start Color and End Color flow along the contour. A higher range increases the speed. The default is 20.
Coverage	Controls the spacing between the lines along the contour. A higher value ensures even distribution, while a lower value increases the gap between lines.
Offset	Horizontal offset (X): Enables horizontal transformation of the entire effect along the X-axis, providing flexibility in positioning the lines. Vertical offset (Y): Enables vertical transformation of the entire effect along the Y-axis, enabling adjustments in the positioning of the applied lines.
Rotation	Select one of three alignment options (None, Normal, Tangent, and Random) that control the rotation of lines along the contour. This feature aligns lines with contour normals or tangents, enhancing visual accuracy.
Zoom	Allows you to scale the entire effect from the center. Negative values shrink the contour towards the center, while positive values enlarge it.
Noise Frequency and Amplitude	These properties control the Perimeter Growth noise frequency and amplitude for each individual line. Adjusting these parameters adds line variation and organic movement to the applied lines.
Flip Horizontally and Flip Vertically	These properties allow you to flip the contour along the X or Y axis, providing additional customization options for the applied lines.
