Can't save image for barcode generation in ASP.NET C# project
I'm trying to save an image using System.Drawing.Save() and I keep getting a Invalid Parameter exception.

Can somebody please take a look at my code and tell me what I'm doing wrong.

Here is the code that generates the barcode image.

     public class BarcodeHelper
        {
            Font barcodeFont;
            public BarcodeHelper()
            {
                 PrivateFontCollection fonts;
                 FontFamily family = LoadFontFamily("~/../fonts/Code128bWin.ttf", out fonts);   
                 barcodeFont = new Font(family, 20.0f);   
    
                // when done:   
                barcodeFont.Dispose();   
                family.Dispose();   
                family.Dispose();
            }
            public FontFamily LoadFontFamily(string fileName, out PrivateFontCollection fontCollection) 
            { 
                fontCollection = new PrivateFontCollection(); 
                fontCollection.AddFontFile(fileName); 
                return fontCollection.Families[0]; 
            }
    
            public Image GenerateBarcode(string barcodeText) 
            {
                Image barcodeImage;
                using (barcodeImage = Image.FromFile(@"C:\Users\Administrator\Desktop\YodelShipping\YodelShipping\images\barcode.bmp"))
                {
                    using (Graphics g = Graphics.FromImage(barcodeImage))
                    {
                        g.DrawString(barcodeText,
                            new Font(barcodeFont, FontStyle.Bold), Brushes.Black, 
                            barcodeImage.Height /2, barcodeImage.Width / 2);
                    }
                }
                return barcodeImage;
            }
        }

Here is where I call the code to create and save the barcode image. I'm getting the exception, when calling the Save() method.

    System.Drawing.Image img = barcodeHelper.GenerateBarcode("2lgbub51aj+01000002");
    img.Save("~/images/barcode.png");
