Rotates a ColdFusion image at a specified point by a specified angle.

imageRotate(name [, x] [, y] , angle [, interpolation]) → returns void

Member Function Syntax

someImage.rotate([, x] [, y] , angle [, interpolation])

imageRotate Argument Reference

name string

The image on which this operation is performed.

angle numeric

The rotation angle in degrees.

x numeric
Default: 2

The x coordinate for the point of rotation

y numeric
Default: 2

The y coordinate for the point of rotation

interpolation string

Type of interpolation
  • nearest: Applies the nearest neighbor method of interpolation. Image quality is lower than the other interpolation methods, but processing is fastest (default).
  • bilinear: Applies the bilinear method of interpolation. The quality of the image is less pixelated than the default, but processing is slower.
  • bicubic: Applies the bicubic method of interpolation. Generally, the quality of image is highest with this method and processing is slowest.

Examples sample code invoking the imageRotate function

Tag Syntax

This example shows how to rotate an image by 10 degrees.

<cfset myImage=imageRead("")><!--- Rotate the image by 10 degrees. ---> 
 <cfset imageRotate(myImage,10)> 
 <cfimage source="#myImage#" action="writeToBrowser"> 

Using rotate member function
