Image.flush介绍

[英]Flushes all resources being used by this Image object. This includes any pixel data that is being cached for rendering to the screen as well as any system resources that are being used to store data or pixels for the image. The image is reset to a state similar to when it was first created so that if it is again rendered, the image data will have to be recreated or fetched again from its source.

This method always leaves the image in a state such that it can be reconstructed. This means the method applies only to cached or other secondary representations of images such as those that have been generated from an ImageProducer (read from a file, for example). It does nothing for off-screen images that have only one copy of their data.
[中]刷新此图像对象正在使用的所有资源。这包括缓存以渲染到屏幕的任何像素数据，以及用于存储图像数据或像素的任何系统资源。图像将重置为与第一次创建时类似的状态，因此如果再次渲染，则必须重新创建图像数据或从其源重新获取图像数据。
这种方法总是使图像处于可以重建的状态。这意味着该方法仅适用于图像的缓存或其他二级表示，例如从ImageProducer生成的图像（例如，从文件读取）。它对只有一份数据拷贝的屏幕外图像没有任何作用。
