Title: How do I make CAPTCHA easy to read?
Post by: comicart on September 12, 2006, 02:59:38 PM

I have changed the $captcha_height = 70; and the $captcha_text_size to 20 and $captcha_text_transparency = 85;

But how do I make the CAPTCHA easier to read? Not as wavey and distorted?

it would be equal to no captcha at all...

Ok - how about "easier" to read (instead of "easy"). Just a little? :)
Is that not an option?

Attached is a sample of the kind of distortion which is too hard to read...

in includes/captcha_utils.php play with these numbers:

Code: [Select]

  $h = rand(5, 10);

[EDIT]
did you scale the attached image? why is it so pixelated? or your server only has GD1 and not GD2?

Thank you!! Changed to 3 and 6 and it looks much smoother.
You're the best V@no.

No, I didn't scale the image, but I did change the size of the graphic and size of the fonts (as noted above). The CAPTCHA image was just too huge on the page.
I'm using GD2.
