Blurry Barcode Edges

[Billzum]

The bar codes being generated have blurry edges. What is causing this and is there any way to fix it? See attached image for a sample

After some additional trial and error testing, I determined that it was the rotation of the barcode image that caused this. (settings.Rotate = 90)

Code: Select all

        private static byte[] GenerateCode39Barcode(Code39BarcodeSchema data)
        {
            BarcodeSettings settings = new BarcodeSettings();
            settings.Type = BarCodeType.Code39;
            settings.BarHeight = 9;
            settings.Data = data.ToString();
            settings.ShowText = false;
            settings.Rotate = 90;
            settings.WideNarrowRatio = 2.4666f;
            settings.X = 0.5f;

            BarCodeGenerator generator = new BarCodeGenerator(settings);
            var image = generator.GenerateImage();
            using (MemoryStream stream = new MemoryStream())
            {
                image.Save(stream, ImageFormat.Png);
                var imageBytes = stream.ToArray();
                return imageBytes;
            }
        }

The easiest response is to use your software, I did this in vb.net
Try
Dim bi As Image = generator.GenerateImage()
bi.RotateFlip(RotateFlipType.Rotate90FlipNone)
BarcodeImg = bi
Catch x As Exception
MsgBox("Barcode Generator error")
BarcodeImg = Nothing
End Try
