ASCII Art Generator/Converter

[nine7ySix]

I've written an ASCII Art Generator/Converter with PHP.

The code can be found here http://fuzzicode.com/scripts/asciiartgenerator.

 

I was wondering if anyone could suggest a way to improve the accuracy of the images produced.

I was hoping to see if anyone knew if they could make a list of 51 characters (or any relatively large number that 255 is divisible by) that go from:

Take up most space -> Take up least space

 

An example of a character that would take up a lot of space would be @ or #, a character that would take up very little space would be . or even a space.

 

Here is the .txt file for verification

Thanks a lot!

 

Any other feedback or suggestions are appreciated!
