Will it throw any exception? It would have taken less time to simply try that than it took you to write and post the message. Of course it will cause an exception, the binary formats of bitmaps and JPEGs are quite different and there is no good way to figure out the image format from a binary stream. -- Peter Below (TeamB) Use the newsgroup archives : http://www.mers.com/searchsite.html http://www.tamaracka.com/search.htm http://groups.google.com http://www.prolix.be Back to top Jens Gruschel Guest Posted: Sun Jun 20, 2004 9:48 pm    Post subject: Re: Tbitmap savetostream Quote: I am using TBitmap to save a picture stream, then I've tried to load the stream using TJpegImage. Will it throw any exception? Just in case you don't know: MyJPegImage.Assign(MyBitmap) should do what you want. BTW: be careful with TJPegImage and LoadFromStream. If your stream contains more than one jpeg image you will get into trouble because after TJPegImage.LoadFromStream the stream's position is set wrong, not at the end of the jpeg image, but a more or less random number of bytes behind that (except if the stream contains nothing else after the image).
