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
Default: nearest

Type of interpolation

nearest: Applies the nearest neighbor method of interpolation. Image quality is lower than the other interpolation methods, but processing is fastest.
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.
  • nearest
  • bilinear
  • bicubic

Sample code invoking the imageRotate function

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"> 

CF 11+ Rotate an image

imgObj = imageRead("");
cfimage(action="writeToBrowser", source=imgObj);
