Chameleon Brush

Chameleon Brush copies a fragment of an image from one part to another with respect to the color range, tone, texture, illumination, and other characteristics of the background, to which the clone is applied. Unlike the Clone Stamp tool, this preserves the characteristics of the underlying image. Cloning can be performed within the same layer, between different layers, or between open images.

To clone an object first choose Chameleon Brush from the left, and select an image source by holding down Alt (Option on Mac), and click the left mouse button over the area from which the cloned fragment will be selected.

Once the reference point is defined, move the cursor to another location. To place the cloned fragment click the left mouse button. When the left mouse button is released, a cross-shaped cursor will appear over the source area, to indicate from where the clone fragment is selected.


The basic tool settings are shown in the Tool Options panel above the Image Window or by right-clicking on the image. To display the full list of parameters, press the tool icon in the Tool Options panel or use the F5 key. To specify the parameter settings, enter a numerical value in the parameter’s field or use the slider.

In addition to the above-mentioned parameters, you can adjust the advanced settings that affect the shape and position of the clone.


Press the Default button to set all settings to their default values.

To draw a straight line, first specify the starting point with the left mouse button, then, while keeping Shift pressed, move the cursor to the desired end point of the line and release Shift. If Shift is not released, a new line will be drawn to each point where the mouse is clicked.
