方法名：getScaledInstance

Image.getScaledInstance介绍

[英]Creates a scaled version of this image. A new Image object is returned which will render the image at the specified width and height by default. The new Image object may be loaded asynchronously even if the original source image has already been loaded completely. If either the width or height is a negative number then a value is substituted to maintain the aspect ratio of the original image dimensions.
[中]创建此图像的缩放版本。将返回一个新的Image对象，默认情况下，该对象将在指定的width和height位置渲染图像。即使原始源映像已完全加载，也可以异步加载新的Image对象。如果width或height为负数，则替换一个值以保持原始图像尺寸的纵横比。
