report viewer pass image from form possible?

Question

Using visual Studio ultimate 2012.

Im currently building a report to be printed in report viewer. so far i have a bunch of text boxes that Gets its values from my form text boxes via parameters.

So far all works fine.

Then I hit a major problem. How do you pass an Image From my images on my form to an image on a report? 1 image pre exists on a database i beleive i can call into the image as a parameter(not sure). the bigger issue is the other image.

The other image uses an external API that generates QR images. this image is displayed in a picture box on my form at runtime. I am not saving the image anywhere i would prefer not too. BUT i understand if i may need to. Is there any way at all i can pass the QR image from the image box on my form to my report Image box?

Update heres the code for the error:

Microsoft.Reporting.WinForms.ReportParameter rpIMG1 = new Microsoft.Reporting.WinForms.ReportParameter("paramQRimg", base64String);
Microsoft.Reporting.WinForms.ReportParameter rpIMG2 = new Microsoft.Reporting.WinForms.ReportParameter("paramQRMi", "image/png");

reportViewer1.LocalReport.SetParameters(new Microsoft.Reporting.WinForms.ReportParameter[] { rp1, rp2, rp3, rp4, rp5, rp6, rp7, rp8, rp9, rp10, rpIMG1, rpIMG2 });

Error occurs on the set Parameters part all it says is:

An error occurred during local report processing.

no idea why it doesn't like this

Answer 1

 public string ImageToBase64(Image image, 
  System.Drawing.Imaging.ImageFormat format)
{
  using (MemoryStream ms = new MemoryStream())
  {
    // Convert Image to byte[]
    image.Save(ms, format);
    byte[] imageBytes = ms.ToArray();

    // Convert byte[] to Base64 String
    string base64String = Convert.ToBase64String(imageBytes);
    return base64String;
  }
}

Convert your image to base64 string and then pass it to your report as parameter and then set the Report image to this parameter.
