Available Annotation Tools

...

  • Going Home: Navigating to the home screen in ICE Igloo Core Engine will clear any current annotations.

  • New Session: Loading a new session will also clear existing annotations.

Configuration

The annotation tool can be tailored to specific preferences. This customisation is achieved by modifying the config.json file located in C:\\igloo\\igloo-core-service. Below is a guide on how to configure these settings.

Accessing the Configuration File

  1. Locate the File: Navigate to C:\\igloo\\igloo-core-service on your system.

  2. Open config.json

Customization Options

The annotation section of the config.json file contains several parameters that you can customize:

  • "defaultColour": Sets the default colour for the pen and shapes. For example, "white" sets the default color to white. You can change this to any valid color name or hexadecimal colour code e.g. “#ff0000” for red.

  • "defaultFontSize": Adjusts the default font size for text annotations.

  • "defaultStrokeWidth": Defines the default stroke width for the pen and shapes.

  • Position Settings: These settings define the positions of various elements in the annotation interface. Each position is determined by x (horizontal) and y (vertical) coordinates:

    • "eraserMenuPos": Position of the eraser menu.

    • "sidebarPos": Position of the sidebar.

    • "toolMenuPos": Position of the tool menu.

    • "clearAllPos": Position of the 'Clear All' option.

    For example, "x": 0, "y": 0 places the element at the top-left corner of the canvas and "x": 50, "y": 50 places the element in the middle of the canvas top-left aligned.

Applying Changes

  1. Edit the Values: Change the values in the annotation section as per your requirements.

  2. Save the File: After making the changes, save the config.json file.

  3. Refresh the annotation page
