Hello,

First of all thank you for going through the code and putting up all those feedback.

I saw few files on MATLAB File-exchange and outside of it that convert images into ASCII text files. They gave those images fun-look.
The main intention when I made this code was to take a snapshot of those text files, so that one could see the whole text file without scrolling.

For more info please google for "text to image".

About using ASCII char set, yes that was one option, but then I am not using all the characters from the ASCII set, I am only using 95 ASCII characters, so even if I try to replace strfind, in the revised code I would have to still use
some sort of index finding method.

I followed your suggestion to do pre-allocation for att2, which gave me appreciable speed-up, so a big thank you to you! Pre-allocation won't be easy in the earlier part because of the variable nature of the sizes.

Thanks again!

Yes you can insert as many images as you want, as long as you are not using more than 100 percentage of the source image(see the screenshot). It was clearly said in the description.

Nurul,

If input_img and output_img are the input and output filenames, this is how you run it:
>> autocontrast(input_img,output_img);

Thanks!

Thanks!!!
