Hi sir,

   i try with ur example with txt file that one i get empty value

I want to generate the omr template for tiff file. i use below code to generate the.

Dim openImage As Aspose.Imaging.Image = Aspose.Imaging.Image.Load("D:\QRcode sample\OMR\SKMBT_C22423121111390.tif")
       Dim tiffImage As Aspose.Imaging.FileFormats.Tiff.TiffImage = TryCast(openImage, Aspose.Imaging.FileFormats.Tiff.TiffImage)
       If tiffImage Is Nothing Then Return

        For Each tiffFrame As Aspose.Imaging.FileFormats.Tiff.TiffFrame In tiffImage.Frames
           Dim ms As MemoryStream = New MemoryStream()
           tiffFrame.Save(ms, New Aspose.Imaging.ImageOptions.PngOptions())
           Dim generationResult As Aspose.OMR.Generation.GenerationResult = omrEngine.GenerateTemplate(ms)
            generationResult.Save("", "D:\QRcode sample\OMR\Hello.OMR")
       Next

Dim templatePath As String = "D:\QRcode sample\omr\hello.omr.omr"
        Dim engine As OmrEngine = New OmrEngine()
        Dim templateProcessor As TemplateProcessor = engine.GetTemplateProcessor(templatePath)
        Dim TIFFImagePath As String = "D:\QRcode sample\OMR\SKMBT_C22423121111390.tif"
        Dim result As RecognitionResult = templateProcessor.RecognizeImage("D:\QRcode sample\omr\hello.omr.png", 60)
        Dim exportPath As String = "D:\QRcode sample\OMR\Photo1Results.csv"
        File.WriteAllText(exportPath, result.GetCsv())

Looks like you have shared the same TIFF image that you shared before in your previous post.

We have been checking it and as soon as ticket is resolved, we will be sharing updates with you in this forum thread. You can check the ticket attached at the bottom of this forum thread.

Hello @psd.senthilnathan

  1. In 23.6.1 release we have introduced extended support for multipage files via “Aspose.OMR.Api.TemplateProcessor.Recognize”. Release notes: Aspose.OMR for .NET 23.6.1 - Release Notes

  2. This line:

Dim generationResult As Aspose.OMR.Generation.GenerationResult = omrEngine.GenerateTemplate(ms)

ms variable holds byte array of tiff frame, which is incorrect.

omrEngine.GenerateTemplate accepts .txt.json files for template generation (images and .omr markup file)
memory stream overload is exists to support application without access to file systems (Cloud solutions) and contains same .txt.json but as byte stream.

For more see: Stages of the OMR process|Documentation

  1. Am I understanding correctly - you have an existing template you wish to recognize using Aspose.OMR?
