I am reading binary data image from a serial port device how can i write it to a black and white image file. The project is a bill counting machine which solution. the device scans images of serial number of bill counted including the data counter

Below is the data returned from the device as read and written to a text file the unreadable strings are the binary data of the serial numbers of each bill counted. i want to read those data and write the raw binary data to image

What I have tried:

I have tried several ways to write to file 100 x 24 image but i only get black image with some blur with pixels across it. below is my code

private void serialPort1_DataReceived(object sender, SerialDataReceivedEventArgs e)
    {
        try
