Re: Pixels

Hey

I was wondering (and couldnt find a clear answer) what happens when I 'draw' a line like this, line("text", 10, 20.5). Seeing that there is no such thing as half a pixel how does processing determine the y location for drawing the line?

Cheers,

line("text", 10, 20.5)

no such method...

you can't draw half a pixel but you can fake half a black pixel, say, by making the whole pixel grey. this is called anti-aliasing and it's used to make things look smoother than is possible by colouring whole pixels.

draw a line, save the image and examine it in a graphic editor and you'll see. (however, i don't think all render modes support this)

To play with what happens when you don't do this -- which forces pixels to be either present or absent with no antialiasing -- experiment with noSmooth().
