C program for text to image

Hi im karthikeyan from National Univ of Sing,

can any one tel the progrm of how to read a text file which has 64x64 characters and to display that as an image, i have copied the contents of the file below.

actually all the zero should be black so that it forms the back ground, and all the characters from 1-9 and A-V should be assigned an intensity level, from 1-31 in the 32 bit level.

The image should be white center part and black background showing ABC and 123.

the text is,

00000000000000000000000000000000000000000000000000 00000000000000

And you have a problem solving which part of the task? We don't "do" other peoples homework on this site - we will help you solve the problem, but you need to do SOME of the work yourself.

actually im new to C, i dont know how to input the text file, im not asking for full solution, but
is there any chance to input the data nd get the image.
because i started the process withh matlab,
my friends told that we can solve this in C much simpler

A C program can open and read the text file.... and then eventually call some supplied graphics function to display pixels. Then you're into Windows calls which aren't technically a C programming problem. Alternatively you could construct a GIF file as your target. Also not really an issue that these forums address. You need to find out what tools are available.

You open a file with fopen.
You read a file with, well, with a lot of things. fgets, fscanf, fread....
You close a file with fclose.

Unless you have to produce an image file, like a bitmap or a pixmap, you could use curses or ncurses...ncurses at least will let you set color intesities on a scale of 1000.

But that's probably not the answer you really want/need. If this is really an assignment, surely there is some particular method you have been asked to use?

If i was you I would get an API such as SDL, which will let you set up a window and display graphics.

Setup a screen buffer with the dimensions set to you files COL/ROW size, then run though each character and each pixel together setting the pixel value based on the character value. Then flip the image into view and delay for a few seconds so you can see it before quitting.
