@vic: remove the last line of your class file: highlight_file(__FILE__);

@Alix:
I generated the patterns (about 30) and tryed to launch Read() but returns nothing.
I get no errors and i think i did everything right.

Train OCR:
$ocr->Train(’testing’,'65751′,’images/capt.jpg’);
(did it 30 times with different capt.jpg and its associated code

Read:
$ocr->Read(’testing’,'crypt2.jpg’, ‘FFFFFF’);

This doesnt give my anything… here’s the URL for the captcha i want to read : meilleurduweb.com/test/cryptimage.php
thx for help,
miko

[code]
Train(’example-captcha’, ‘A’, ‘A-crop.jpg’);
$OCR->Train(’example-captcha’, ‘C’, ‘B-crop.jpg’);
$OCR->Train(’example-captcha’, ‘B’, ‘C-crop.jpg’);
$OCR->Train(’example-captcha’, ‘D’, ‘D-crop.jpg’);
$OCR->Train(’example-captcha’, ‘E’, ‘E-crop.jpg’);
$OCR->Train(’example-captcha’, ‘F’, ‘F-crop.jpg’);
$OCR->Train(’example-captcha’, ‘G’, ‘G-crop.jpg’);
$OCR->Train(’example-captcha’, ‘H’, ‘H-crop.jpg’);
$OCR->Train(’example-captcha’, ‘I’, ‘I-crop.jpg’);
$OCR->Train(’example-captcha’, ‘J’, ‘J-crop.jpg’);
$OCR->Train(’example-captcha’, ‘K’, ‘K-crop.jpg’);
$OCR->Train(’example-captcha’, ‘L’, ‘L-crop.jpg’);

$OCR->Train(’example-captcha’, ‘P’, ‘P-crop.jpg’);
$OCR->Train(’example-captcha’, ‘Q’, ‘Q-crop.jpg’);
$OCR->Train(’example-captcha’, ‘R’, ‘R-crop.jpg’);
$OCR->Train(’example-captcha’, ‘S’, ‘S-crop.jpg’);
$OCR->Train(’example-captcha’, ‘T’, ‘T-crop.jpg’);
$OCR->Train(’example-captcha’, ‘U’, ‘U-crop.jpg’);
$OCR->Train(’example-captcha’, ‘V’, ‘V-crop.jpg’);
$OCR->Train(’example-captcha’, ‘W’, ‘W-crop.jpg’);
$OCR->Train(’example-captcha’, ‘X’, ‘X-crop.jpg’);
$OCR->Train(’example-captcha’, ‘Y’, ‘Y-crop.jpg’);
$OCR->Train(’example-captcha’, ‘Z’, ‘Z-crop.jpg’);

echo $OCR->Read(’example-captcha’, ‘http://localhost/OCR/default.png’, ‘FFFFFF’);
[code]

i host the file in
c:\program files\xampp\htdocs\OCR\ocrtest.php
c:\program files\xampp\htdocs\OCR\ocr-class.php
c:\program files\xampp\htdocs\OCR\[alphabet]-crop.jpg

and the result is the ocr-class.php code’s…confusing

Carroll, it seems to me that you haven’t created an example of a class, like this:

include(’ocr.php’);
$ocr= new OCR;
$ocr->train(blablabla);

Hey,
Your script looks great, I’m just having trouble trying to get it to work. I get an error : “Fatal error: Call to a member function on a non-object in /home/*****1/domains/**********.***/public_html/***/test.php”
when i try to train the class. My code is ”
Train(’tracer-l’, ‘D’, ‘letters/D.gif’);
?>
Any idea what could be causing this problem as I’d love to be able to use your very helpful class
