Convert image to Java image
jimage = im2java(I)
jimage = im2java(X,MAP)
jimage = im2java(RGB)
To work with a MATLAB® image in the Java® environment, you must convert the image from its MATLAB representation into an instance of the Java image class, java.awt.Image.
The input image can be of class uint8, uint16, or double.
Note Java requires uint8 data to create an instance of the Java image class, java.awt.Image. If the input image is of class uint8, jimage contains the same uint8 data. If the input image is of class double or uint16, im2java makes an equivalent image of class uint8, rescaling or offsetting the data as necessary, and then converts this uint8 representation to an instance of the Java image class, java.awt.Image.
This example reads an image into the MATLAB workspace and then uses im2java to convert it into an instance of the Java image class.
I = imread('ngc6543a.jpg'); javaImage = im2java(I); frame = javax.swing.JFrame; icon = javax.swing.ImageIcon(javaImage); label = javax.swing.JLabel(icon); frame.getContentPane.add(label); frame.pack frame.show
