如何在Delphi 2010中更改TWICImage的像素格式

我有一个TWicImage、IWicBitmap和一个IWicBitmapSource，可以很好地显示所有支持的图形文件格式，允许旋转、水平翻转、垂直翻转、缩放和剪切。所有这些看起来都很好，我可以得到WicImages的像素格式，但我不知道如何更改或设置TWicImage的像素格式

我创建了一个对话框，返回WICPixelFormatGUID作为转换的像素格式

任何人都可以分享一些代码来演示如何使用IWICColorTransform或其他Wincodec方法更改WicImage的像素格式吗

账单

现在已经是2011年的中期了。。。因此，对于那些可能想知道的人来说，我尝试了这个方法，它似乎起到了作用（它使用了Developer Express提供的TcxImage，但我怀疑TImage也会起作用）：

Bummi和Warren p要求我发布我之前添加的答案。答案如下：

+1，无论如何，你可以简单地使用这个函数，而不需要格式转换器。嗨，比尔，你的答案在德尔福未回答问题的顶部。如果我读对了，你就解决了问题，把你的答案写进你的问题里。你能把答案放在回答区并接受它吗？现在是11月，还没有完成，我建议有人为他做这件事，并附上归因。
