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

// Creates an instance of FileStream
com.aspose.imaging.system.io.FileStream stream = new com.aspose.imaging.system.io.FileStream("C:\\temp\\output.png", com.aspose.imaging.system.io.FileMode.Create);

    // Create an instance of PngOptions and set its various properties
    com.aspose.imaging.imageoptions.PngOptions pngOptions = new com.aspose.imaging.imageoptions.PngOptions();

    // Set the Source for PngOptions
    pngOptions.setSource(new com.aspose.imaging.sources.StreamSource(stream));

    // Create an instance of Image
