[pygame] Re: Sprite Surface very slow to draw

[SurferIX <olivier.pons@xxxxxxxxx>]

If found the solution!
The problem is that the documentation needs examples (or maybe I
didn't find good ones):
I was using:
 40         self.image.convert_alpha()
I should have done:
 40         self.image.convert_alpha(self.image)
(which I don't understand btw)

So the final class which works is:

 22 class Contour(pygame.sprite.Sprite):
 23     def __init__(self,width,height,speed):
 24         pygame.sprite.Sprite.__init__(self) #call Sprite
initializer
 25         self.width = width
 26         self.height = height
 27         self.rect  = pygame.Rect(0, 0, width, height)
 28         self.image = pygame.Surface( (self.rect.width,
self.rect.height) )
 29         self.image.set_colorkey((0,0,0))
 30         self.image.fill((0, 0, 0))
 31         pygame.draw.rect(self.image, (105,250,230), self.rect, 5)
 32         self.fadeout = False
 33         if speed<1:
 34             raise Exception("Speed must be > 0")
 35         self.speed = speed
 36         self.alpha = 250
 37         self.done = False
 38         self.image.set_alpha(self.alpha)
 39         self.image = self.image.convert()
 40         self.image.convert_alpha(self.image)

By the way, I'm doing:
 39         self.image = self.image.convert()

and I don't know whether I should call it or if

 40         self.image.convert_alpha(self.image)

does the whole stuff.
Any help would be greatly appreciated!
