To draw a circle on a canvas, use the following methods: beginPath - begins a path; arc(x,y,r,startangle,endangle) - creates an arc/curve. To create a circle with arc: Set start angle to 0 and end angle to 2.Math.PI. The x and y parameters define the x- and y-coordinates of the center of the circle.

In this part of the Tkinter tutorial we will do some drawing. Drawing in Tkinter isdone on the
Canvas widget. Canvas is a high-level facilityfor doing graphics in Tkinter.
It can be used to create charts, custom widgets, or create games.
Tkinter canvas
A canvas widget manages a 2D collection of graphical objects — lines, circles, images, or other widgets. It is suitable for drawing or building more complex widgets.
Tkinter draw lines
A line is a simple geometric primitive. The
create_line method creates a line item on the Canvas .
lines.py
In the code example, we draw simple lines.
The parameters of the
create_line method are thex and y coordinates of the start and end points of the line.
A vertical line is drawn. The
dash option specifiesthe dash pattern of the line. We have a line consisting of alternating segmentsof 4 px dash and 2 px space.
The
create_line method can take multiple points. Thisline draws a triangle.
Tkinter colours
A colour is an object representing a combination ofRed, Green, and Blue (RGB) intensity values.
Canvas Draw 6 0 2 X 2
In the code example, we draw three rectangles and fill them withdifferent colour values.
We create the
Canvas widget.
The
create_rectangle creates a rectangle itemon the canvas. The first four parameters are the x and y coordinatesof the two bounding points: the top-left and bottom-right points.With the outline parameter we control the colour ofthe outline of the rectangle. Likewise, the fill parameter provides a colour for the inside of the rectangle.
Tkinter geometric shapes
We can draw various shapes on the
Canvas .The following code example will show some of them.
shapes.py
We draw five different shapes on the window: a circle, an ellipse,a rectangle, an arc, and a polygon. Outlines are drawn in red andinsides in green. The width of the outline is 2px.
Here the
create_oval() method is used to create a circleitem. The first four parameters are the bounding box coordinates ofthe circle. In other words, they are x and y coordinates of the top-leftand bottom-right points of the box, in which the circle is drawn.
We create a rectangle item. The coordinates are again the bounding boxof the rectangle to be drawn.
This code line creates an arc. An arc is a part of the circumference ofthe circle. We provide the bounding box. The
start parameteris the start angle of the arc. The extent is the angle size.
A polygon is created. It is a shape with multiple corners. To create apolygon in Tkinter, we provide the list of polygon coordinates to the
create_polygon method.
Tkinter draw image
In the following example we draw an image item on the canvas.
The example displays an image on the canvas.
From the PIL (Python Imaging Library) module, we import the
Image and ImageTk modules.
Canvas Draw 6 0 2 X 2 Answer
Tkinter does not support JPG images internally. As a workaround, weuse the
Image and ImageTk modules.
We create the
Canvas widget. It takes the size of the imageinto account. It is 20px wider and 20px higher than the actual image size.
We use the
create_image method to create an image itemon the canvas. To show the whole image, it is anchored to the north andto the west. The image parameter provides the photo imageto display.
Tkinter draw text![]() Canvas Draw 6 0 2 X 20 44 X
In the last example, we are going to draw texton the window.
draw_text.py
We draw lyrics of a song on the window.
Canvas Draw 6 0 2 X 2
The first two parameters are the x and y coordinates of thecenter point of the text. If we anchor the text itemto the west, the text starts from this position. The
font parameter provides the font of the text and the text parameter is the text to be displayed.
In this part of the Tkinter tutorial, we did some drawing.
