How to do it…Įxecute the program as shown in the previous image.Ĭhart_1 = Canvas(root, width=cw, height=ch, background=”white”)Ĭycle_period = 100 # time between new positions of the ball (milliseconds). However, if you are a friend of mathematics it is fun to watch sine, cosine, and tangent working together to make a child smile.
#BEST RASTER GRAPHICS EDITOR 2018 CODE#
If you do not like mathematics you can just cut and paste the code without the need to understand exactly how the maths works. You will see some trigonometry in the code. We will be using Tkinter and time modules to animate the movement of lines and circles. The math is needed to provide the trigonometry that sustains the geometric relations that move the parts of the leg in relation to each other. We import Tkinter, math, and time modules. We want to use these legs together with pieces of raster images and see how far we can go in making appealing animations. We make a pair of walking legs using the vector graphics. We have used a black background so the black corners on the image of our beach ball cannot be seen. The size of this box, called the bounding box, is the size of the image. The photo type images always occupy a rectangular area of screen. The image of the beach ball is shifted across a canvas.

In the example below, the instruction, ball = PhotoImage(file = “constr/pics2/beachball.gif”) says that the image to be used will be found in a directory (folder) called pics2, which is a sub-folder of another folder called constr.Ĭanvas_1 = Canvas(root, width=cw, height=ch, bg=”black”)īall = PhotoImage(file = “/constr/pics2/beachball.gif”)įor i in range(1,100): # end the program after 100 position shifts.Ĭanvas_1.create_image(posn_x,posn_y,anchor=NW, image=ball)Ĭanvas_1.update() # This refreshes the drawing on the canvas.Ĭanvas_1.after(cycle_period) # This makes execution pause for 100 milliseconds.Ĭanvas_1.delete(ALL) # This erases everything on the canvas. gif fle from somewhere and paste it into a directory where you want to keep your work-in-progress pictures.Įnsure that the path in our computer’s fle system leads to the image to be used. An example of one, named beachball.gif has been provided. We need a suitable GIF image of an object that we want to animate. To keep things simple and clear we are just going to move a photographic image (in GIF format) of a beach ball across a black background. We want to animate a raster image, derived from a photograph. We will also see how to use “The GIMP” as a tool to prepare images suitable for animation. We need to work exclusively with GIF format images because that is what Tkinter deals with.
