- getPhrase(), allow you to get the phrase contents
- setDistortion($distortion), enable or disable the distortion, call it before
build() - isOCRReadable(), returns
trueif the OCR can be read using theocradsoftware, you'll need to have shell_exec enabled, imagemagick and ocrad installed - buildAgainstOCR($width = 150, $height = 40, $font = null), builds a code until it is not readable by
ocrad - build($width = 150, $height = 40, $font = null), builds a code with the given $width, $height and $font. By default, a random font will be used from the library
- save($filename, $quality = 80), saves the captcha into a jpeg in the $filename, with the given quality
- get($quality = 80), returns the jpeg data
- output($quality = 80), directly outputs the jpeg code to a browser
- setBackgroundColor($r, $g, $b), sets the background color to force it (this will disable many effects and is not recommended)
- setBackgroundImages(array($imagepath1, $imagePath2)), Sets custom background images to be used as captcha background.
