How to convert a .txt file to any image format

I have a .txt file which contains the data of image in numbers as I am new to matlab I need some help figuring this out .

All i need is to convert this .txt file into any image format like a jpeg,jpg or anything. I tried attaching the file but after reducing it is 6mb so this site is not accepting it but i added a screenshot of it below . If you are intrested in this I can email you the file afer looking into the screenshot.

Thank you in advance

The contents of the file does not contain enouh information to understand the format completely. The initial "2 2 1 1" might be important or not. Without knowing, what these values mean, it is impossible to create an image, which displays exactly, what is written to the text file.

So the frist step ist to find a documentation of the file format. Then It should be more or less easy to write a code for the conversion.

Thank you for the response

I dont have a description of this file all i know is it is a huge file which contains each pixel values mostly zeros but has some 1 which tells me it is a black and white image.

I can send the file if you are intrested in helping me out .

A text file without a clear and unique defintion abouts its format is completely useless. You cannot be sure, if your interpretation is correct. So search in the documentation of the program, which has created the file, or ask the author. If you do not get an exact definition, the best you can do is to delete the file, because it is a waste of time only and you cannot draw any reliable conclusions from it.

ok thank you for the reply.

I have what a output should look like does that help?

It would still require some or a lot of guessing. Such an "reverse engineering" of created outputs is too fragile. Therefore this is not a reliable method for scientific work.

I recommend to get the exact definition of the file format. This should be possible.

I am sharing a link for the file, if you scroll down 750 lines you can see x,y values. I think those values are pixels.

The values could be positions of pixels, or RGB values of pixels on a grid, or difference to the former pixel, or something else. Guessing is not reliable. Why don't you ask the author of the software, which has created the file? Asking authors is the standard method to obtain information.
