示例1: rotate
# 需要导入模块: from SimpleCV.ImageClass import Image [as 别名]
# 或者: from SimpleCV.ImageClass.Image import rotate [as 别名]
def rotate(self,angle):
"""
Rotate the blob given the angle in degrees most of the blob elements will
be rotated, not however this will "break" drawing back to the original image.
To draw the blob create a new layer and draw to that layer.
Parameters:
angle - Int or Float
