Converting DIB to JPEG

[brivers]

I've got a framegrabber card that will let me grab frames from a video source. The API gives me a handle to a DIB when I grab an image. Is there any easy way of saving this to a JPEG with C++Builder 5?

I've looked at TJPEGImage and TImage::Bitmap, but I can't figure out how to get those from a handle.
