Public Methods

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. It then constructs a byte array the same size as the image. 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);

Parameters:

array - input array from which to create a renderedImage

Returns:

renderedImage created from the input array

Inherited Methods

Methods inherited from class java.lang.Object.

`clone`	`clone()` Used to create and return a copy of the object it is called on. This method is protected and provides a shallow copy, meaning it copies the values of an object's fields directly. For fields that are objects, it copies references, not the objects themselves.
`equals`	`equals()` Used to compare two objects for equality. It checks if the two objects are the same in terms of their content, rather than just comparing their references. By default, the `equals()` method compares the memory locations of objects (similar to the `==` operator). However, it is commonly overridden in subclasses to provide a more meaningful equality comparison based on the properties of the objects.
`finalize`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`getClass`	`public final Class<?> getClass()` Returns the runtime class of this Object.
`hashCode`	`hashCode()` Used to return a hash code value for the object. This integer value is used for efficiently storing objects in hash-based collections like `HashMap`, `HashSet`, and `HashTable`. The general contract of `hashCode()` is that if two objects are equal according to the `equals()` method, they must return the same hash code. It's important to override `hashCode()` in a manner consistent with `equals()` to maintain this contract.
`notify`	`public final void notify()`
`notifyAll`	`public final void notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`wait`	`public final void wait(long timeout, int nanos) throws InterruptedException` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
