Re: [pygame] Maybe a bug in pygame.draw.circle?

[PyMike <pymike93@xxxxxxxxx>]

You might be able to go like:

img = pygame.Surface((100, 100))
pygame.draw.circle(img, (255, 255, 255), (0, 0), 50)
pygame.draw.circle(img, (0, 0, 0), (20, 20), 30)
img.set_colorkey((0, 0, 0), pygame.RLEACCEL)

That might work. What it would do is draw a circle to an image, and a smaller black one over it. The img would then set a colorkey and would replace the black in the image with alpha. I haven't tested this yet but it might work :-)

Cheers,

Hi, we found a posible bug in "pygame.draw.circle" function using
pygame1.8 (we don't try with
other versions).

When we set a circle border, the "pygame.draw.circle" function puts
some little pixels
like noise. This is a screenshot of the posible bug:

and this is a sample code:

--- %< ---
import pygame

WHITE = (255, 255, 255)
position = 100, 100
screen = pygame.display.set_mode((320, 240))

pygame.draw.circle(screen, WHITE, position, 50, 20)
pygame.display.flip()
pygame.time.wait(1000)
--- %< ---

note that when remove the 50 value of border, the circle will draw fine:

Thanks!

 

This is because a thick circle is created by drawing a series of single pixel-width circles. I don't know what can be done about this.
