Good day I am using Viewer 2.12 now
Please Look at the below webservice I cannot give you the Helper code.
But all that The JsonConvert.DeserializeObject<List>(Helpers.TapeHelper.DoRequest("Document", "ws_getimagepath",
new
{
ImageNumber = imageNumber
},
Properties.Settings.Default.TapeEnvironmentCode).ToString()); return a list that does is has filename extention and bytes for each file. in the list .
public class SD
{
public string FilenameExtension { get; set; }
public byte[] Stream { get; set; }
}

I dont understand why its not displaying the file as the below code it does return the stream to the viewer.
