本文整理了Java中org.eclipse.jface.resource.ResourceManager.createImage方法的一些代码示例，展示了ResourceManager.createImage的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ResourceManager.createImage方法的具体详情如下：
包路径：org.eclipse.jface.resource.ResourceManager
类名称：ResourceManager
方法名：createImage

ResourceManager.createImage介绍

[英]Creates an image, given an image descriptor. Images allocated in this manner must be disposed by #destroyImage(ImageDescriptor), and never by calling Image#dispose().

If the image is intended to remain allocated for the lifetime of the ResourceManager, the call to destroyImage may be omitted and the image will be cleaned up automatically when the ResourceManager is disposed. This should only be done with short-lived ResourceManagers, as doing so with the global manager effectively leaks the resource.
[中]在给定图像描述符的情况下创建图像。以这种方式分配的图像必须由#destroyImage（ImageDescriptor）处理，而决不能通过调用Image#dispose（）处理。
如果该映像打算在ResourceManager的生命周期内保持分配状态，则可以省略对destroyImage的调用，并且在处置ResourceManager时，该映像将被自动清除。这只能通过短期的ResourceManager来完成，因为使用global manager这样做实际上会泄露资源。
