[TYPO3-typo3org] little rant about TER captcha (but not only)

Hi Robert !!


I took myself the time to look at the TER code - and as soon as I noticed that
it uses the "captcha" extension available from TER i checked this one out and
had a look at it.

It seems Kasper just quickly took some script he found on the Web and conformed
to the GPL and made the captcha library out of it.

I completly rewrote the extensions captcha/captcha.php file ....

Here is a link to my new version:

Just install it like usual - but this time you can make a mass of settings in the
Extension Managers install configuration.

First of all I would suggest what we render the captchas using TTF fonts which is
possible by checking the first option - you then need to change "letterSpacing" to 3 or 4
because in TTF mode letter spacing is the "distance" between two letters while in normal
mode it is the distance between the starts of two letters)


I'm sure you will find settings which suit the needs of the average visitor giving feedback
on TYPO3.

Here are some screenshots from the generated captchas:

A normal one:

A Bold one:

One bad to type:

And a psychodelic one:

I could easily add code that in the morning hours between 3 and 5 the psychodelic one is shown :)



greets,
Bernhard
