试图将文本旋转 90

Question

I am using Tkinter and CanvasPlus library to rotate the text by 90 degrees but I am not able to rotate. This is the code I am trying

self.circle = self.canvas.create_circle(0, 0, self.circle_radius, fill=self.bg_color, 
                                        outline="green", width=3)

self.label_ready_for_cooking = self.canvas.create_label(0, 0, font=("Arial", 28),
                                                        fg="white", bg=self.bg_color, 
                                                        text="READY\nFOR", anchor="be")

self.canvas.rotate(self.label_ready_for_cooking, 10, 10, 90, unit="deg")

The image is showing but I am not able to rotate the image. How can I do this?

With reference to the GitHub Wiki of this library

CanvasPlus.rotate() There's no easy way to rotate something in tkinter. Usually, there's a lot of math and trig that is put into it. This method uses complex numbers to rotate a polygon clockwise in radians or degrees.

Basically all the transformations are only applicable to polygons and not any of theWidget Windows .

UPDATE

You could achieve what you are looking for by using the angle parameter of create_text in the default Canvas widget of tkinter .

Try this

from tkinter import *

root=Tk()

canvas=Canvas()
canvas.pack()

canvas.create_text(100,100,text='Rotated Text',angle=90)

root.mainloop()

Note that angle option is available in tk 8.6.x. @ acw1668
