How to Randomly Duplicate Objects in Inkscape
The Spray tool in Inkscape is a powerful feature that allows you to quickly disperse multiple copies of an object or path across your canvas. By adjusting specific settings in the tool’s control bar, you can introduce random variations in rotation, scale, and scatter. This technique is ideal for creating natural-looking textures, starry skies, crowds, or scattered foliage without manually copying and placing every single element.
Step 1: Select Your Source Object
Before activating the tool, you need to tell Inkscape what you want to duplicate. Select the object, path, or group you wish to spray using the Select and Transform Objects tool (F1 or S).
Step 2: Activate the Spray Tool
Click on the Spray objects icon in the left-hand toolbar, or simply press A or Space + A on your keyboard to switch to the tool.
Step 3: Configure for Random Distribution
To achieve a truly random duplication effect, look at the tool control bar at the top of the screen and adjust the following parameters:
- Mode: Choose the first icon (Spray copies of the initial selection) to create independent duplicates, or the second icon (Spray clones) if you want the duplicates to automatically update whenever you change the original object.
- Width: This adjusts the size of the spray brush circle.
- Population: Controls how many items are dropped per second or per pixel moved.
- Rotation: Turn this value up (e.g., to 50 or higher) to randomly rotate each duplicate as it is sprayed.
- Scale: Increase this percentage to randomly vary the size of the duplicated objects, making some larger and some smaller than the original.
- Scatter: Raise this value to increase the chaotic spread of the objects within your brush radius.
Step 4: Spray Across the Canvas
Click and drag your mouse across the canvas. Inkscape will continuously duplicate the selected object within the brush radius, applying the random constraints you defined in the settings. If you place too many objects in one spot, you can use the Prevent overlapping toggle in the control bar to ensure the duplicates maintain a specified distance from one another.
