Also specified, whether the original unprocessed picture is deleted.
/// /// Add a copyright information on the image /// /// Original image /// Output Image /// copyright picture /// Whether to delete the original picture /// copyright picture displayed X-axis coordinate /// copyright picture displayed Y-axis coordinate public void createcopyrightImage (String FileName, String Outfilename, String Copyrightfile, bool deleteFile, float x, float y) {System.Drawing.Image image = System.Drawing.Image.FromFile (fileName); System.Drawing.Image c_image = System.Drawing.Image.FromFile (copyRightFile); System.Drawing. Bitmap outPut = new System.Drawing.Bitmap (image); System.Drawing.Graphics g = System.Drawing.Graphics.FromImage (outPut); g.DrawImage (c_image, x, y); string extend = fileName.Substring (fileName .Lastindexof (".") 1) .tolower (); switch (extend) {copy "bmp": Output.save (outfilename, system.drawing.imaging.imageformat.bmp); Break; Case "JPG": Output .Save (Outfil) eName, System.Drawing.Imaging.ImageFormat.Jpeg); break; case "gif": outPut.Save (outfileName, System.Drawing.Imaging.ImageFormat.Gif); break; case "icon": outPut.Save (outfileName, System.Drawing.Imaging.ImageFormat.Icon); break; case "png": outPut.Save (outfileName, System.Drawing.Imaging.ImageFormat.Png); break; case "tif": outPut.Save (outfileName, System. Drawing.Image.imageFormat.tiff); Break;
