my first try to use jsui - I started by editing (a copy of) the 360° dial (the one which is in the help file), and want to get rid of the background (the white square in which is the dial) - to have just the round dial.

If I got it right the colors are in the RGBA values, and when i can change the color of the background, I can not make it disappear

changing the values of the first 3 params (RGB) works, when the last one (A) does not seem to make any effect

arguments: fgred fggreen fgblue bgred bggreen bgblue dialred dialgreen dialblue

what i do is messing with
var vbrgb = [1.,1.,1.,1];

sketch.default2d();
var val = 0;
var vbrgb = [1.,1.,1.,1];
var vfrgb = [0.2,0.2,0.2,1];
var vrgb2 = [0.7,0.7,0.7,1];
var last_x = 0;
var last_y = 0;

I think (emphasis on "think" here) that is the alpha-color. Try setting it to zero and my guess is that the color won't show. Or set it to 0.5 and place another object behind it, if my assumptions are correct it will be partially transparent.

i hoped that with alpha at zero and anything behind i would see onlt what is behind. but no

well yes, i also THOUGHT this.
but doing so i see no difference

I think you may be stuck with a white background but other things you draw should be able to have variable opacity. I could be wrong but I remember a discussion about the pros and cons of [jsui] by itself and [js] with [lcd] which can have a transparent background.

Check out some of the jsui mgraphics examples. They do transparency.

some of your design? could not find what it is.......

Sorry. In the Max examples folder. /Max6/examples/javasript/ui-mgraphics/ holds some patches... look for mgraphics-yellowfade.maxpat.

You have forgot to initialize the other string values. The first are x x x, the second are y y y and so on. That means that the string are in form of "x x x y y y z z z", or better $1 $2 $3 $4 $5 $6 $7 $8 $9.

If you want to change only the first, there's no problem because you have to send only $1 $2 $3, if you want to send two full color parameters, use $1 $2 $3 $4 $5 $6, but if you want to change only the second, change $4 $5 $6 but you have so send $1 $2 $3 too (memorize the values before), etc.

Maximum $ values are 9.
