Hey guys,
I just found this little problem with setting the font size for the captcha helper, this is the current code and as it is right now, the font size that user set will never work
if ($use_font == FALSE)
{
$font_size = 5;
$x = rand(0, $img_width/($length/3));
$y = 0;
}
else
{
$font_size = 16;
$x = rand(0, $img_width/($length/1.5));
$y = $font_size+2;
}
I just added that piece of code to my project and it works very well, maybe that should be updated for next version of CI.
if(isset($data["font_size"]))
$font_size = $data["font_size"]; //The font size value the user set
else
$font_size = 16; //Default
if ($use_font == FALSE)
{
////$font_size = 5;
$x = rand(0, $img_width/($length/3));
$y = 0;
}
else
{
////$font_size = 16;
$x = rand(0, $img_width/($length/1.5));
$y = $font_size+2;
}
Hope I explained well… let me know what you think 
Cheers!
