Ellipses rendering in processing 2.0b7

in General Discussion • Other • 10 months ago

I just noticed that ellipses in processing 2.0b7 are rendered differently from previous versions, and doesn't appear to be ellipses, see images below:

from 2.0b6

from 2.0b7

anyway the pdf output display ellipses correctly...

Yeah, it's visible. It could also be (a change in) the default smoothing settings maybe?

I haven't worked with the 2.0 betas a lot, but I believe you can set very different levels of smoothing.

seems like the default smoothing setting is a smooth(). This, along with a default stroke setting, shows the issue.

but the ellipses without a stroke and the default smooth display normally...

in the end seems like the issue is stroke-related.... isn't it?

actually i'm working with these 2.0xx versions because of it seems like more and more libraries are update to this...

and also because I would like to familiarize with changes before they become too many... :D

All the changes are exactly the reason why I stay away from the betas. I only want to make the leap once when the changes are final and the documentation is up to date.

Anyway, have you tried it with: hint(DISABLE_OPTIMIZED_STROKE);

you're right about keeping away from 2.0xx, dealing with changes is awful and I would like to stay with 1.5.1... :|

hint(DISABLE_OPTIMIZED_STROKE);

doesn't work :(

If something is going backwards, please file a bug with an example that we can look into. The only way we can improve things if you let us know about it via the bugs database.

ok, I'm sending a sketch to the issue page on google code here: http://code.google.com/p/processing/issues/list

to me it seems related with colorMode HSB and some particular diameter value for ellipse...

meanwhile I post also here: result and code below

use keys 't', 'h', 'm' to toggle stroke/noStroke, colorMode HSB/RGB and smooth/noSmooth. Also 's' key to save, 'b' to erase background and mouse click to add new ellipse..

boolean ustroke = true;
boolean mou = true;
boolean hsbrgb = true;
String cm, mooo;
void setup() {
size(600, 400);
colorMode(HSB, 360, 360, 360);
background(255);
frameRate(5);
smooth();
background(175);
noLoop();
}
void draw() {
if (mou) {
smooth();
println("we are smoothing");
mooo = "smooth()";
}
else {
noSmooth();
println("we are NOT smoothing");
mooo = "noSmooth()";
}
if (!ustroke) {
noStroke();
}
else {
stroke(0);
}
if (hsbrgb) {
colorMode(HSB, 360, 360, 360);
println("colorMode is HSB");
cm = "HSB";
}
else {
colorMode(RGB, 255, 255, 255);
println("colorMode is RGB");
cm = "RGB";
}
}
void keyPressed() {
redraw();
switch(key) {
case 't':
ustroke = !ustroke;
break;
case 'm':
mou = !mou;
break;
case 'h':
hsbrgb = !hsbrgb;
break;
case 'b':
background(175);
break;
case 's':
save("strokeTest.png");
break;
}
}
void mousePressed() {
float diam = random(5, 30);
ellipse(mouseX, mouseY, diam, diam);
String specs = "diam = " +diam+
"\ncolorMode = "+cm +
"\n"+ mooo;
text(specs, mouseX - diam/2, (mouseY +diam/2)+22);
redraw();
}
