Examples of java.awt.Toolkit.createImage()

java.awt.Toolkit.createImage()
Returns an image which gets pixel data from the specified file. The returned Image is a new object which will not be shared with any other caller of this method or its getImage variant.
This method first checks if there is a security manager installed. If so, the method calls the security manager's checkRead method with the specified file to ensure that the image creation is allowed. @param filename the name of a file containing pixel datain a recognized file format. @return an image which gets its pixel data fromthe specified file. @throws SecurityException if a security manager exists and itscheckRead method doesn't allow the operation. @see #getImage(java.lang.String)
