image.rotate()

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

image.rotate( x=string, y=string, angle=string, interpolation=string )

Returns: Image

Argument Description
x
string, required

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

y
string, optional

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

angle
string, optional

The rotation angle in degrees.

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

imgObj = imageNew("",200,200,"rgb","red");
	imgObj.rotate(50,50,60,"bilinear");
	cfimage(action = "writeToBrowser",source = imgObj);
	writeoutput("<br><br>");
	img1 = imageNew("",100,100,"RGB","blue");
	img1.rotate(60,40,120);
	cfimage(action = "writeToBrowser",source = img1);
