About this Project

This is only a small program that I wrote for fun :) You are welcome to try and play with it.
The purpose of this program is to convert an image (only .jpeg tested) to a txt file which only contains several charactors.
Note: For better visual effect, please use fixed-width font to view the file, such as monospace.
Note: Now only an html will be generated after running the program, so that you can view it in any browser.

Requirement

opencv > 2.0
cmake > 3.0
make

How to use

Clone this project under any directories and run make.
Usage:

./img2char <img file name> (optional)<width> (optional)<I>  
<width> : maximum characters per row in the output file.  
<I> : whether inverse the color.  

##Example Following are two outputs from a heart image with width 20 and 50 respectively.
Note: For better visual effect, try view output html files using a browser.
