Re: Re: [pygame] keep-aspect scale

["Leonardo Santagada" <retype@terra.com.br>]

I never used the transform module but if it asks for x and y sizes of the
final image you just have to multiply x and y for the factor that you want
to scale. Just try this
scalefactorx = (framex - oldx)/oldx
scalefactory = (framey - oldy)/oldy

if scalefactorx < scalefactory then
 newx = oldx * saclefactorx
 newy = oldy * saclefactorx
else
 newx = oldx * saclefactory
 newy = oldy * saclefactory

image = pygame.transform.scale( image, (new_x,new_y) )

I don't know if i am right but i just wake up and I don't want to load
python to try this.
