Triangle Visualization

Class: TriangleVisualizationBlockV1

Source: inference.core.workflows.core_steps.visualizations.triangle.v1.TriangleVisualizationBlockV1

The TriangleVisualization block draws triangle markers on an image at specific coordinates based on provided detections using Supervision's sv.TriangleAnnotator.

Type identifier

Use the following identifier in step "type" field: roboflow_core/triangle_visualization@v1to add the block as as step in your workflow.

Properties

Name	Type	Description	Refs
name	str	Enter a unique identifier for this step..	❌
copy_image	bool	Enable this option to create a copy of the input image for visualization, preserving the original. Use this when stacking multiple visualizations..	✅
color_palette	str	Select a color palette for the visualised elements..	✅
palette_size	int	Specify the number of colors in the palette. This applies when using custom or Matplotlib palettes..	✅
custom_colors	List[str]	Define a list of custom colors for bounding boxes in HEX format..	✅
color_axis	str	Choose how bounding box colors are assigned..	✅
position	str	The anchor position for placing the triangle..	✅
base	int	Base width of the triangle in pixels..	✅
height	int	Height of the triangle in pixels..	✅
outline_thickness	int	Thickness of the outline of the triangle in pixels..	✅

The Refs column marks possibility to parametrise the property with dynamic values available in workflow runtime. See Bindings for more info.
