13. ImageDraw pieslice

See: https://pillow.readthedocs.io/en/stable/reference/ImageDraw.html#PIL.ImageDraw.ImageDraw.pieslice

13.1. Pieslice

Use the ImageDraw.pieslice(xy, start, end, fill=None, outline=None, width=1) method to draw a pieslice like an arc with straight lines between the end points and the center of the bounding box. This modifies the image, in place.

ImageDraw.pieslice(xy, start, end, fill=None, outline=None, width=1): xy - Two points to define the bounding box.

Sequence of [(x0, y0), (x1, y1)] or [x0, y0, x1, y1], where x1 >= x0 and y1 >= y0.

start - Starting angle, in degrees. Angles are measured from 3 o’clock, increasing clockwise.

end - Ending angle, in degrees.

fill - Color to use for the fill.

outline - Color to use for the outline.

width - The line width, in pixels.

The code below draws a blue rectangle on a new white image.

from PIL import Image, ImageDraw


im = Image.new('RGB', (256, 256), "white")
drw = ImageDraw.Draw(im, 'RGB')

shape = [(40, 40), (220, 220)]
drw.pieslice(shape, start = 0, end = 270, fill ="#33ff33", outline ="#000033")

shape = [(60, 20), (240, 200)]
drw.pieslice(shape, start = 270, end = 360, fill ="#0000ff", outline ="#000033")

im.save("ImageDraw/ImageDraw_pieslice.png")
# im.show()
