Render MATLAB Image Data in Java
This section contains code snippets intended to demonstrate specific functionality related to working with figure and image data.
Working with Images
Get Encoded Image Bytes from Image in Component
public byte[] getByteArrayFromDeployedComponent()
{
Object[] byteImageOutput = null;
MWNumericArray numericImageByteArray = null;
try
{
byteImageOutput =
deployment.getImageDataOrientation(
1, //Number Of Outputs
500, //Height
500, //Width
30, //Elevation
30, //Rotation
"png" //Image Format
);
numericImageByteArray =
(MWNumericArray)byteImageOutput[0];
return numericImageByteArray.getByteData();
}
finally
{
MWArray.disposeArray(byteImageOutput);
}
}
Get Buffered Image in Component
public byte[] getByteArrayFromDeployedComponent()
{
Object[] byteImageOutput = null;
MWNumericArray numericImageByteArray = null;
try
{
byteImageOutput =
deployment.getImageDataOrientation(
1, //Number Of Outputs
500, //Height
500, //Width
30, //Elevation
30, //Rotation
"png" //Image Format
);
numericImageByteArray =
(MWNumericArray)byteImageOutput[0];
return numericImageByteArray.getByteData();
}
finally
{
MWArray.disposeArray(byteImageOutput);
}
}
public BufferedImage getBufferedImageFromDeployedComponent()
{
try
{
byte[] imageByteArray =
getByteArrayFromDeployedComponent()
return ImageIO.read
(new ByteArrayInputStream(imageByteArray));
}
catch(IOException io_ex)
{
io_ex.printStackTrace();
}
}
Create Buffered Images from MATLAB Array
Use the renderArrayData
method to:
Create a buffered image from data in a given MATLAB® array.
Verify the array is of three dimensions (height, width, and color component).
Verify the color component order is red, green, and blue.
See
renderArrayData
in the Java® API documentation for information on input parameters, return values, exceptions thrown, and examples.
