Returns the enum representing the storage format of the pixels managed by this PixelFormat object.

Usage

From source file:Main.java

/**
 * Determine the optimal BufferedImage type to use for the specified
 * {@code fxFormat} allowing for the specified {@code bimg} to be used
 * as a potential default storage space if it is not null and is compatible.
 * //from   ww  w. ja va 2 s.  c o m
 * @param fxFormat the PixelFormat of the source FX Image
 * @param bimg an optional existing {@code BufferedImage} to be used
 *             for storage if it is compatible, or null
 * @return
