How to Spray Objects

1Choose Spary Tool

On the Main Ribbon Bar, switch to the "Edit" category. Find the "Spary Tool" tool button on the "Edit Tools" panel. Click to select it. As shown below.

2Choose the most Suitable Filling Options

The Spray Tool is to Copy or Clone the currently selected object to the canvas where the user clicks or drags. Therefore, before using the Spray Tool, be sure to use the Selection Tool to select one or more objects. Otherwise, it has no effect.

When the Spray Tool is used as the current editing tool, a series of related options will appear on the right control panel. As shown below.

• Mode: It will decide how to create the sprayed objects.
  • Spray with Copy: Copy the original selected object each time, and then spray the copied copy onto the canvas. It should be noted that the copied object and the original object are independent of each other.
  • Spray with Clone: The objects sprayed on the canvas are clones of the original selected objects. Cloning is not the same as copying. It just establishes a link to the original object. If the rendering style of the original object, such as the fill color, is changed, the cloned object will change accordingly. In other words, the cloned object has a high degree of dependence on the original object.
  • Single Path: Combine all the paths of objects sprayed on the canvas into a single object with complex paths.
• Width: This value defines the size of the spray area. The value ranges from 1 to 100. This value is a percentage ratio in a relative sense, not an absolute length mark in pixels or other measurement units. The larger the value, the objects sprayed from the spray tool will be distributed in a wider and wider area. On the contrary, they are distributed in a small, dense area.

  Width = 3.0	Width = 15.0	Width = 30.0

• Amount: Used to control the number of objects sprayed from the Spray Tool on each click. The setting range of this value is 1-100. It is also a percentage ratio in a relative sense. The larger the value is, the more objects will be copied or cloned from the spray gun each time you click, and vice versa.

  Amount = 20	Amount = 50	Amount = 70

• Rotation: This value is also a percentage ratio in a relative sense. When the copied or cloned object is sprayed, it will rotate another angle around the center position. This value is not aimed at describing the angle, but the range of angle. Where 0 means no change, no rotation, and 50 means that the object will rotate by an angle between -180 and 180.

  Rotation = 0	Rotation = 10	Rotation = 25

• Scale: It is also a percentage ratio in a relative sense. Describes that the copied or cloned object scaling range after being sprayed. Setting it to 0 means that the object has no scaling changes. A setting of 50 means that the object may be enlarged by 50% or shrinked by 50% of the original object.

  Scale = 0	Scale = 10	Scale = 25

• Scatter: It is essentially a standard deviation value. The standard deviation can reflect the degree of dispersion of a data set. The smaller the standard deviation, the less these values deviate from the average, and vice versa. This refers to the extent to which the copied or cloned object deviates from its original position. The greater the value is set, the greater the deviation will be.

  Scatter = 1.0	Scatter = 20.0	Scatter = 50.0

• Focus: This value is also a percentage ratio in a relative sense. It describes the mean value of the deviation of the position of the copied or cloned object from its original position after spray. The greater the value is set, the greater the deviation will be. Set to 0 to focus on one spot.

  Focus = 0.0	Focus = 20.0	Focus = 50.0

3Spray by Clicking or Drag

Move the mouse on the canvas to the position to be sprayed, click the left mouse button, keep the mouse pressed down, and drag the mouse. The spray tool will copy or clone the selected objects at each position experienced.
