TIFF Image with CCITT Group 4, TIFF 6.0 Date Time Tag not retaining

[Rajasekaran.A]

We need to Convert the Grayscale TIFF into Black & White TIFF as per the following specification:

Input: TIFF (Grayscale, LZW Compression, version 6.0)

Output: TIFF

                Color Mode: Black & White

                Compression: CCITT Group 4,

                TIFF Version: 6.0

                TIFF tag: Date and time of image creation (Code: 306) 

We have tried to converting the above format using some application, the Date and time tag is removing after saving CCITT Group 4 compression. Customer required to retain the Date & time tag in the Black & White TIFF image with CCITT Group 4 compression.

So Kindly let us know any application for converting Group 4 compression with Date Time TIFF tag.

Thanks in Advance
