ImageFormat

Enumerates all BotDetect Captcha image output formats.

ImageFormat Enumeration Members
PHP Captcha ImageFormat enumeration member Jpeg Captcha images will be converted to the JPEG image format. Results in good image quality and reasonable image sizes; used by default
PHP Captcha ImageFormat enumeration member Gif Captcha images will be converted to the GIF image format. Only suitable for some image styles, resulting in lower image quality with the more color dynamic image styles
PHP Captcha ImageFormat enumeration member Png Captcha images will be converted to the PNG image format. Results in good image quality and image size, but not supported in older versions of Internet Explorer (would be used by default if this wasn't the case)

SoundFormat

Enumerates all BotDetect Captcha sound output formats.

SoundFormat Enumeration Members
PHP Captcha SoundFormat enumeration member WavPcm16bit8kHzMono The default format, used for underlying Captcha sound generation. Reasonable sound quality for Captcha purposes, resulting in moderate sound file sizes. Supported by most clients
PHP Captcha SoundFormat enumeration member WavPcm8bit8kHzMono Lower quality Wav format option, resulting in smaller sound file downloads while retaining good enough quality in most cases

CodeUsePurpose

Enumerates all BotDetect Captcha code generation purposes.

CodeUsePurpose Enumeration Members
CodeUsePurpose enumeration member ImageGeneration The Captcha code will be used for Captcha image generation
CodeUsePurpose enumeration member SoundGeneration The Captcha code will be used for Captcha sound generation
CodeUsePurpose enumeration member Other The Captcha code will be used for a purpose which is neither Captcha image nor Captcha sound generation

ValidationAttemptOrigin

Enumerates all BotDetect Captcha validation attempt origins. Different origins can result in different validation rules being applied.

ValidationAttemptOrigin Enumeration Members
ValidationAttemptOrigin enumeration member Unknown The validation origin isn't set
ValidationAttemptOrigin enumeration member Server The validation attempt is a result of server-side code called from a full form submission
ValidationAttemptOrigin enumeration member Client The validation attempt is a result of server-side code called from an Ajax call

BotDetect_SoundRegenerationMode

Enumerates all BotDetect Captcha sound regeneration modes.

BotDetect_SoundRegenerationMode Enumeration Members
BotDetect_SoundRegenerationMode enumeration member None Generate only one sound response per Captcha code, cache it on the server, and serve it for all consecutive sound requests.
BotDetect_SoundRegenerationMode enumeration member Limited Allow generation of a limited number of different sound responses (the minimum required to make Captcha audio work in all supported client browsers and devices), and automatically change the Captcha code on the client for consecutive sound requests if needed and possible.
BotDetect_SoundRegenerationMode enumeration member Unlimited Each audio request will generate a new Captcha sound response (previous BotDetect version behavior).
