Syntax:

<Cfimage action = "CAPTCHA" fontsize = "font size"
Width = "Verification Code image width" Height = "Verification Code Image Height"
TEXT = "Verification Code text" fonts = "Verification Code font"
Difficulty = "difficulty">

Note:

1. ColdFusion automatically adds a random background and automatically skews text.
2. difficulty can have three values: low, high, and medium. Different levels of difficulty indicate the complexity of the verification code image!

Example:

General difficulty: <cfimage action = "CAPTCHA" fontsize = "25" width = "180" Height = "50" text = "r1adte" fonts = "Arial, verdana, courier New ">

Moderate difficulty: <cfimage action = "CAPTCHA" fontsize = "25" width = "180" Height = "50" text = "r1adte" fonts = "Arial, verdana, courier New "Difficulty =" medium ">

High difficulty: <cfimage action = "CAPTCHA" fontsize = "25" width = "180" Height = "50" text = "r1adte" fonts = "Arial, verdana, courier New "Difficulty =" high ">
