    • Constructor Detail

      • Brush

        public Brush()
    • Method Detail

      • getOpacity

        public float getOpacity()

        Gets the brush opacity. The value should be between 0 and 1. Value of 0 means that brush is fully visible, value of 1 means the brush is fully opaque.

        Returns:
        The brush opacity value.
      • setOpacity

        public void setOpacity(float value)

        Sets the brush opacity. The value should be between 0 and 1. Value of 0 means that brush is fully visible, value of 1 means the brush is fully opaque.

        Parameters:
        value - The brush opacity value.
        Code example:

        This example uses Graphics class to create primitive shapes on the Image surface. To demonstrate the operation, the example creates a new Image in PNG format and draw primitive shapes on Image surface using Draw methods exposed by Graphics class
