Retrieve Embedded Images on Reports

Recently I had to build a report where some images were required, although I did not have those images they were available on other reports as embedded images.

From https://msdn.microsoft.com/en-us/library/dd239394.aspx I found which embedded images are stored on reports within its report definition (rdl file) base64 encoded.

So I took the next steps to build the images I needed to add on the new report:

1. Report definition file stores images on the EmbeddedImages element. So, I copied that section and created an new XML file.

<?xml version="1.0" encoding="utf-8" ?>
<EmbeddedImages>
  <EmbeddedImage Name="logo">
    <MIMEType>image/png</MIMEType>
    <ImageData>image base64 encoded</ImageData>
  </EmbeddedImage>
</EmbeddedImages>

1. Then created a C# console application with the code bellow to create the image file from the XML file and got the images to add to the report.

XDocument xDoc = new XDocument();
xDoc = XDocument.Load("ReportImages.xml");

foreach (XElement xElem in xDoc.Elements("EmbeddedImages").Elements("EmbeddedImage"))
{
	String name = xElem.Attribute("Name").Value;
	String type = xElem.Element("MIMEType").Value;
	String data = xElem.Element("ImageData").Value;

	String fileName = String.Format("{0}.{1}", name, type.Substring(type.IndexOf('/') + 1));
	File.WriteAllBytes(fileName, Convert.FromBase64String(data));
}
