## Class SwingFXUtils

- java.lang.Object
- - javafx.embed.swing.SwingFXUtils

-     public class SwingFXUtils
      extends Object

  This class provides utility methods for converting data types between Swing/AWT and JavaFX formats.
  Since:
    JavaFX 2.2

- - ### Method Summary

    All Methods Static Methods Concrete Methods
    Modifier and Type | Method | Description
    --- | --- | ---
    `static BufferedImage` | `fromFXImage​(Image img, BufferedImage bimg)` | Snapshots the specified JavaFX `Image` object and stores a copy of its pixels into a `BufferedImage` object, creating a new object if needed.
    `static WritableImage` | `toFXImage​(BufferedImage bimg, WritableImage wimg)` | Snapshots the specified `BufferedImage` and stores a copy of its pixels into a JavaFX `Image` object, creating a new object if needed.

    - #### toFXImage

          public static WritableImage toFXImage​(BufferedImage bimg,
                                                WritableImage wimg)

      Snapshots the specified `BufferedImage` and stores a copy of its pixels into a JavaFX `Image` object, creating a new object if needed. The returned `Image` will be a static snapshot of the state of the pixels in the `BufferedImage` at the time the method completes. Further changes to the `BufferedImage` will not be reflected in the `Image`.

      The optional JavaFX `WritableImage` parameter may be reused to store the copy of the pixels. A new `Image` will be created if the supplied object is null, is too small or of a type which the image pixels cannot be easily converted into.

      Parameters:
        `bimg` - the `BufferedImage` object to be converted
        `wimg` - an optional `WritableImage` object that can be used to store the returned pixel data
      Returns:
        an `Image` object representing a snapshot of the current pixels in the `BufferedImage`.

        JavaFX 2.2

    - #### fromFXImage

          public static BufferedImage fromFXImage​(Image img,
                                                  BufferedImage bimg)

      Snapshots the specified JavaFX `Image` object and stores a copy of its pixels into a `BufferedImage` object, creating a new object if needed. The method will only convert a JavaFX `Image` that is readable as per the conditions on the `Image.getPixelReader()` method. If the `Image` is not readable, as determined by its `getPixelReader()` method, then this method will return null. If the `Image` is a writable, or other dynamic image, then the `BufferedImage` will only be set to the current state of the pixels in the image as determined by its `PixelReader`. Further changes to the pixels of the `Image` will not be reflected in the returned `BufferedImage`.

      The optional `BufferedImage` parameter may be reused to store the copy of the pixels. A new `BufferedImage` will be created if the supplied object is null, is too small or of a type which the image pixels cannot be easily converted into.

      Parameters:
        `img` - the JavaFX `Image` to be converted
        `bimg` - an optional `BufferedImage` object that may be used to store the returned pixel data
      Returns:
        a `BufferedImage` containing a snapshot of the JavaFX `Image`, or null if the `Image` is not readable.
