Saving Metafiles

Question

I have a problem with saving metafiles. I open *.wmf file into Image and then do Image.Save(filename, ImageFormat.Wmf) but it seems that the saved file is always bmp file. I also tried to use ImageCodecInfo encoder, but when I get the encoders, there isn't one for metafiles (only tif, jpg, gif, bmp and png) Am I missing something, or .net doesn't support saving back metafiles? Thanks.

sorry for getting in to ur conversation. I too have a question. If I insert any .wmf image in an RTF file and when I open the file and try to strect the image with the help of mouse the line width of the image ( say a rectangle) also changes. Can we not fix the parameters of the image like line width such that even if the user changes the image width remains unchanged. Please guide regards

I dont think you can use the Image.Save method edit a metafile. Try this one. 1. Open an existing Metafile using MetaFile class 2. Create a Graphics object using Metafile as following: // Create a metafile with a name using HDC Metafile curMetafile = new Metafile(newFile.wmf hdc); // Create a Graphics object from the Metafile object Graphics g1 = Graphics.FromImage(curMetafile); 3. Now using Graphics class's Draw or Fill methods to edit the image. It should be saved automatically.

OK I have to look at the sample code in my book (Advanced Imaging chapter). I really dont remember. It's been a while.

I am using MetaFile but when I do image.Save(filename ImageFormat.Wmf) it's saved as Bmp. image is instanceof Metafile. When I draw and scale it it displays fine but after I do save and do Image.Fromfile(filename) I get Bitmap. The saved file is bitmap because when I open it in graphics program it is bitmap.

You have to use MetaFile class which is derived from Image.
