Hi Yolanda,

Thanks for your interest in our Aspose.BarCode for .NET product. You can generate the barcode by setting the codetext and selecting the symbology type and then you can insert it into a multi-page TIFF image. For each generated barcode, a new page in multi-page TIFF image will be created.

Please follow the code snippet below:

string[] lstCodeText = new string[] { "code-1", "code-2", "code-3", "code-last" };
Symbology symbology = Symbology.Code128;

// generate separate barcode image as stream
// and save image stream in the array
ArrayList inputImages = new ArrayList();
foreach (string item in lstCodeText)
{
    // get the codetext from array
    string strCodetext = item;
    MemoryStream image = new MemoryStream();
    // generate the barcode
    BarCodeBuilder builder = new BarCodeBuilder(strCodetext, symbology);
    builder.Save(image, ImageFormat.Tiff);
    inputImages.Add(image);
}

CreateMultipageTIF(inputImages, "c:\\test\\name.tiff");

private static void CreateMultipageTIF(ArrayList InputImages, string Filename)
{
    // set the image codec
    ImageCodecInfo info = null;
    foreach (ImageCodecInfo ice in ImageCodecInfo.GetImageEncoders())
    {
        if (ice.MimeType == "image/tiff")
        {
            info = ice;
            break;
        }
    }

    EncoderParameters ep = new EncoderParameters(2);
    bool firstPage = true;
    System.Drawing.Image img = null;
    // create a image instance from the 1st image
    for (int nLoopfile = 0; nLoopfile < InputImages.Count; nLoopfile++)
    {
        //get image from src file
        System.Drawing.Image img_src = System.Drawing.Image.FromStream((Stream)InputImages[nLoopfile]);
        Guid guid = img_src.FrameDimensionsList[0];
        System.Drawing.Imaging.FrameDimension dimension = new System.Drawing.Imaging.FrameDimension(guid);
        //get the frames from src file
        for (int nLoopFrame = 0; nLoopFrame < img_src.GetFrameCount(dimension); nLoopFrame++)
        {
            img_src.SelectActiveFrame(dimension, nLoopFrame);
            ep.Param[0] = new EncoderParameter(System.Drawing.Imaging.Encoder.Compression, Convert.ToInt32(EncoderValue.CompressionLZW));

            // if first page, then create the initial image
            if (firstPage)
            {
                img = img_src;
                ep.Param[1] = new EncoderParameter(System.Drawing.Imaging.Encoder.SaveFlag, Convert.ToInt32(EncoderValue.MultiFrame));
                img.Save(Filename, info, ep);
                firstPage = false;
                continue;
            }

            // add image to the next frame
            ep.Param[1] = new EncoderParameter(System.Drawing.Imaging.Encoder.SaveFlag, Convert.ToInt32(EncoderValue.FrameDimensionPage));
            img.SaveAdd(img_src, ep);
        }
    }

    ep.Param[1] = new EncoderParameter(System.Drawing.Imaging.Encoder.SaveFlag, Convert.ToInt32(EncoderValue.Flush));
    img.SaveAdd(ep);
}

Thanks for the answer but, this code creates a multipage tiff with barcode ... ¿How do I add these images to multipage tiff?

Thanks you again.

Hi Yolanda,


Thanks for the details. I’m afraid. There is no direct way to add image to multipage tiff image file by using Aspose.BarCode product. Besides, you can achieve this by using Aspose.Imaging for .net where you can concatenate multiple TIFF images. Please visit documentation link below:
