Icon Visualization

Class: IconVisualizationBlockV1

Source: inference.core.workflows.core_steps.visualizations.icon.v1.IconVisualizationBlockV1

The IconVisualization block draws icons on an image using Supervision's sv.IconAnnotator. It supports two modes: 1. Static Mode: Position an icon at a fixed location (e.g., for watermarks) 2. Dynamic Mode: Position icons based on detection coordinates

Type identifier

Use the following identifier in step "type" field: roboflow_core/icon_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..	✅
mode	str	Mode for placing icons: 'static' for fixed position (watermark), 'dynamic' for detection-based.	✅
icon_width	int	Width of the icon in pixels.	✅
icon_height	int	Height of the icon in pixels.	✅
position	str	Position relative to detection for dynamic mode.	✅
x_position	int	X coordinate for static mode. Positive values from left edge, negative from right edge.	✅
y_position	int	Y coordinate for static mode. Positive values from top edge, negative from bottom edge.	✅

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