3. ImageDraw arc
3.1. Arc
Use the
ImageDraw.arc(xy, start, end, fill=None, width=0)
method to draw an arc (a portion of a circle outline) between the start and end angles, inside the given bounding box.- ImageDraw.arc(xy, start, end, fill=None, width=0)
- 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 arc.width - The line width, in pixels.
The code below draws a blue arc on a new white image.
from PIL import Image, ImageDraw
im = Image.new('RGB', (256, 256), "white")
drw = ImageDraw.Draw(im, 'RGB')
# im.show()
drw.arc(xy=(20, 40, 236, 216), start=0, end=120, fill="blue", width=5)
im.save("ImageDraw/ImageDraw_arc.jpg")
