Damn Simple PHP ASCII Art Generator
So yesterday I was bored and asked my friend what I should do. She replied "I don't know, draw ASCII art or something!" and sitting there with the terminal open I kind of wondered what it would take to write one of those image to ASCII scripts.
20 minutes later I had the following PHP Shell Script! It works by simply sampling the saturation of every Xth pixel and mapping that saturation to a character from an array. There is no nearest-neighboring or anything like that, just straight up sampling.
#!/usr/bin/php -q <?php
if(isset($argv[1]) && strlen($argv[1])) { $file = $argv[1]; }else{ echo 'Please Specify a File'; exit(1); }
$img = imagecreatefromstring(file_get_contents($file)); list($width, $height) = getimagesize($file);
$scale = 10;
$chars = array( ' ', '\'', '.', ':', '|', 'T', 'X', '0', '#', );
$chars = array_reverse($chars);
$c_count = count($chars);
for($y = 0; $y <= $height - $scale - 1; $y += $scale) { for($x = 0; $x <= $width - ($scale / 2) - 1; $x += ($scale / 2)) { $rgb = imagecolorat($img, $x, $y); $r = (($rgb >> 16) & 0xFF); $g = (($rgb >> 8) & 0xFF); $b = ($rgb & 0xFF); $sat = ($r + $g + $b) / (255 * 3); echo $chars[ (int)( $sat * ($c_count - 1) ) ]; } echo PHP_EOL; }
Huzzah!
And there you have it! A whopping 35 lines of code. There is a ton of tweaking you can do like changing the array of characters, or adjusting the $scale variable which is simply how wide of a sample it makes. Setting it to 1 for instance should sample every pixel on the Y and every other pixel on the X (so it scales propperly). To the right is a sample output of the script.
Do You Trust Me?
The script accepts local or remote image paths as the first argument. The following is a simple usage example you can use to get you started.

It was a fun little project and I look forward to seeing if/what the internet comes up with for it. Fork me on Github, or post links in the comments! Happy hacking!

Nice work man. A simple and clean little thing that is quite a catalyst for the old thought bubbles.

A simple code but prospective. This website http://meapage.com/htart/ may be used a similar methods to generate ASCII Art
