This will and does fail because Surface.rect.center is actually the coordinates of the center of the Rect object relative to the (0,0) point -top left corner- of the display screen, not relative to the (0,0) point of the Rect object. Get the rectangle of the rotated image and set the center position through the center of the original rectangle.<br>\nReturns a tuple from the function <code>red_center</code>, with the rotated image and the bounding rectangle of the rotated image:</p>\n<div class=\"highlight highlight-source-python notranslate position-relative overflow-auto\" .
