Class Image

java.lang.Object

ros.msgs.sensor_msgs.Image

public class Image
extends Object

Implementation of ROS sensor_msgs/Image.msg: http://docs.ros.org/api/sensor_msgs/html/msg/Image.html. This class can also decode the ROS Image into a Java Buffered Image for images that are encoded in either bgr8, rgb8, or mono8, by using the toBufferedImage() method.

Method Detail

toBufferedImage

public BufferedImage toBufferedImage()

Constructs a BufferedImage from this ROS Image, provided the encoding is either rgb8, bgr8, or mono8. If it is not one of those encodings, then a runtime exception will be thrown.

Returns:

a BufferedImage representation of this image.

toBufferedImageFromMono8

protected BufferedImage toBufferedImageFromMono8()

Constructs a BufferedImage from this ROS Image assuming the encoding is mono8

Returns:

a BufferedImage representation of this image.

toBufferedImageFromRGB8

protected BufferedImage toBufferedImageFromRGB8()

Constructs a BufferedImage representation from this ROS Image assuming the encoding is either rgb8 or bgr8.

Returns:

a BufferedImage representation of this image.
