//Image:TImage;Jpg:TJepgImage;
Image.Picture.Bitmap.Handle:=BHandle;
Image.Picture.Bitmap.SaveToStream(ScrStream);
ScrStream.Clear;
Jpg.Assign(Image.Picture.Graphic);
Jpg.Compress;
Jpg.SaveToStream(ScrStream);
这样是对的但是
Image.Picture.Bitmap.Handle:=BHandle;
Jpg.Assign(Image.Picture.Graphic);
Jpg.Compress;
Jpg.SaveToStream(ScrStream);
却错了(raised exception class EOutOfResources with message'参数错误'),为什么?

为什么要使用TImage?
//Bmp: TBitmap; Jpg: TJpegImage;
Bmp.Handle := BHandle;
Jpg.Assign(Bmp);
Jpg.Compress;
ScrStream.Position := 0;
Jpg.SaveToStream(ScrStream);
