ImageRotate

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

ImageRotate( image, x [, y [, angle [, interpolation ] ] ] )

Returns: void

Argument Description Default
image
any, required

The image on which this operation is performed.

Alias: name, source

x
string, required

The x coordinate for the point of rotation. The default value is 2.

2

y
string, optional

The y coordinate for the point of rotation. The default value is 2.

2

angle
string, optional

The rotation angle in degrees.

0

interpolation
string, optional

Type of interpolation:

  • nearest (default): 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.

Examples

img=imageNew("",100,100,"RGB","0fb9b1");
imageRotate(img, "60");
cfimage(action="writeToBrowser",source=img);
