Question

In my scenario i have two tiff image in different location say

I need to merge these imag

Answer 1

To do this using just the Framework classes, you basically do this:

1. Load each of your TIFF images into a Bitmap object, e.g. using Image.FromFile.
2. Save the first page with an encoder parameter Encoder.SaveFlag = EncoderValue.MultiFrame
3. Save each subsequent page to the same file with an encoder parameter of Encoder.SaveFlag = EncoderValue.FrameDimensionPage using Bitmap.SaveAdd()

It would look something like this:

ImageCodecInfo tiff = null;
foreach ( ImageCodecInfo codec in ImageCodecInfo.GetImageEncoders() )
{
    if ( codec.MimeType == "image/tiff" )
    {
        tiff = codec;
        break;
    }
}

Encoder encoder = Encoder.SaveFlag;
EncoderParameters parameters = new EncoderParamters(1);
parameters.Param[0] = new EncoderParameter(encoder, (long)EncoderValue.MultiFrame);

bitmap1.Save(newFileName, tiff, parameters);

parameters.Param[0] = new EncoderParameter(encoder, (long)EncoderValue.FrameDimensionPage);
bitmap2.SaveAdd(newFileName, tiff, paramters);

parameters.Param[0] = new EncoderParameter(encoder, (long)EncoderValue.Flush);
bitmap2.SaveAdd(parameters);
