| | Saving Images ... I have a Metafile that I would like to save as an image. So far, this seems to work fine: Metafile x = new Metafile(myFilename); x.Save(jpgFilename, ImageFormat.Jpeg); While I get the image fine, the background is black. For the life of me, I can't figure out how to make the background white. Any ideas? Somebody please make me feel stupid. Thanks. |

How would I draw the Metafile object into a Bitmap object that has been cleared to a white background? Thanks again. |

Don't forget to dispose your IDisposables.  Pete |
