renderArrayData

public static java.awt.image.BufferedImage renderArrayData(MWNumericArray array)

Create a RenderedImage from the data in the given MWNumericArray. This array must conform to the following restrictions: - must be three dimensions: (height, width, color component) - color component order must be RED, GREEN, BLUE

Example: Converting figure data in a MWArray to a Buffered Image This example takes an MWArray containing figure data and converts it to a buffered image, which is then converted to a byte array formated as a PNG.

Convert figure data output (a three dimensional numeric array) into a buffered image as follows:

      BufferedImage img = Images.renderArrayData((MWNumericArray)mwArray);
      int estimatedSize = img.getHeight()*img.getWidth()*3;
      byteOutputStream = 
                new ByteArrayOutputStream(estimatedSize);
