Creates a ColdFusion image that can be manipulated by using image functions.
You can use the cfimage tag to perform common image manipulation operations as a shortcut to Image functions.
You can use the cfimage tag independently or in conjunction with image functions.

(border) Border color.
Hexadecimal value or supported named color.
For a hexadecimal value, use the form "##xxxxxx" or "xxxxxx". (required)


Absolute or relative pathname where the image output is written.
The image format is determined by the file extension.
The convert and write actions require a destination.
The border, captcha, resize, and rotate actions require either a name attribute or a destination attribute.
You can specify both.
Scorpio supports only CAPTCHA images in PNG format.
If you do not enter a destination, the CAPTCHA image is placed inline in the HTML output and displayed in the web browser.

Default: low

Level of complexity of the CAPTCHA text.
Specify one of the following levels of text distortion:
low Values:
  • high
  • medium
  • low


Font size of the text in the CAPTCHA image.
The value must be an integer.


Format of the image displayed in the browser.
If you do not specify a format, the image is displayed in PNG format.
You cannot display a GIF image in a browser.
GIF images are displayed in PNG format. Values:

Height in pixels of the image.
For the resize attribute, you also can specify the height as a percentage (an integer followed by the "%" symbol).

The isBase64 values are:
yes: the source is a Base64 string.
no: the source is not a Base64 string.

The read action requires name attribute.
The border, resize, and rotate options require a name attribute or a destination attribute.
You can specify both.

Default: false

Valid values are fractions that range from 0 through 1
(the lower the number, the lower the quality).
