Alpha Syntax

Hi, is the syntax for the new alpha transparency the same as in the reference? I tried using color(r, g, b, a); but it didn't work. I tried with floats and with ints.

hello ryan,
alpha hasn't been integrated into the color() function yet. but you can use fill(r, g, b, a) and stroke(r, g, b, a)
+ casey

casey,
stroke(r,g,b,a) is erratic..
// this doesn't render what you want it to...
smooth();
noFill();
stroke(0,0,255,20);
line(10,10,90,90);
stroke(0,0,255);
line(20,30,70,80);
stroke(0,0,255,20);
ellipse(50,50,10,10);

Shoot. I'm guessing that means no Bimage transparency either.. I mean local transparency, not the whole image..

yup, that's the line() bug mentioned under 'known bugs' in the revisions.txt. i hope to have that ironed out for 53.

i haven't tested local transparency much in images, but it may work (the code is in there for rendering, at least). it's possible though that a .gif that has alpha set may not respect the alpha, though you could mess with an image's pixel values to get alpha to work. if it's not behaving, post us a bug report in the bugs section.
whole-image transparency should work, by setting the alpha on the fill().
