ImageToSEGY enables you to save scanned seismic paper records as fully conforming SEG-Y digital data files, complete with time stamps, fix marks, and interpolated navigation. It supports most common graphics file formats including JPEG, TIFF, and BMP. And allows you to specify navigation, time and fix marks in the image and will then interpolate to provide unique time and navigation at each shot point.
Platform:Windows
System Requirements: There is no specific requirements
SEGY file format is a standard format to store seismic data. It has a 3600 byte header out of which first 3200 is textual header and the rest 400 bytes are binary headers.
I want to read integers from this .sgy file that have important information I need. For example I want to read byte number 3217-3218 to retrieve the sample rate i.e these particular 2 bytes are allotted for sample rate.

Similarly bytes 3221-3222 to read 'Number of Samples'. I have the following code. It does not yield the proper integers.
This program should show following results file len as 993204,sample rate as 2 and no of samples as 501 instead it prints file len as 993204,Sample Rate as 53248 and No Of Samples as 62720

Please help. Am I not reading the binary file correctly?
