Working with Images

Getting Encoded Image Bytes from an Image in a 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);
    }
}

Getting a Buffered Image in a 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();
    }
}
