Argumente

Die Argumente für diese Funktion sind fest vorgegeben. Ausser den nachfolgenden Argumenten dürfen keine weiteren verwendet werden.
Name Typ Required Beschreibung
name any  Yes The image on which this operation is performed.  
x string  Yes The x coordinate for the point of rotation. The default value is 2.  
y string  No The y coordinate for the point of rotation. The default value is 2.  
angle string  No The rotation angle in degrees.  
interpolation string  No 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.
