Re: [pygame] Fast method for pixellated animation

[Lenard Lindstrom]

Hi,
 
The Pygame scroll.py example program uses the pygame.transform.scale function to zoom in on an image.
 
https://bitbucket.org/pygame/pygame/src/dd6752f761be/examples/scroll.py
 
It is packaged with Pygame and can be run with the following command line:
 
python -m pygame.examples.scroll

Thanks – I tried this but I'm just learning pygame and just need to get a little higher on the curve I guess.

I'll get it though. Thanks so much again.

The obvious solution is pygame.transform.scale. Whether this is the most efficient method or not depends on how you're generating the image in the first place. But if you've already got a 100x100 image as a pygame.Surface object, and you want to create a 400x400 image out of it, it's clearly the way to go.

Hi,
I would like an efficient way to generate an animated grey-scale
"pixellated" image. For example, to be able to generate an image say of
100 X 100 pixels, where I can specify the size of the image on the screen
(which thus determines the size of the pixels). One way would be to treat
each pixel as a filled rectangle and draw them accordingly, but this could
be quite slow since it has to do this 10,000 times for each image. Another
way might be to just generate the image as a 100X100 image but "magnified"
and thus automatically obtaining the same result. Is this possible? If
not, is there yet another way to do this that might be more efficient?
thanks,
