Filled circle with circular gradient in ruby

[tester]

Could someone post how to draw a circle/ellipse in ruby, that is filled with circular gradient? (one color in the center, other color outside). I'm confused a bit with the manual - it speaks on multipoint/coordinate gradients for polygons; I just need a simple ruby replacement for circle drawing prims.

try this:

Code: Select all

def draw v

c1 = Color.new 0,35,247
c2 = Color.new 210,34,67

r = [2,2,12,12]
p = GraphicsPath.new
p.addEllipse r
b = PathGradientBrush.new p

b.setSurroundColors [c1]
b.setCenterColor c2
b.setCenterPoint 8,8
b.setBlend [[0,0],[1,1],[1,1]]

v.drawEllipse b,r
end

Hey Adam, basically I need to integrate it into something like this. the csiz is diameter (2r). Center should have one color, and outer - second color.

You mean the equivalent of the prims "Ellipse" and "Filled Ellipse"?

Just use a pen for outlines with :drawEllipse
and a brush for fills with :drawEllipse

tester - of course you may ask. What I do or not do is not up to you, but I'm glad you show your animosity, for whatever reason. You're welcome!

Speaking as a moderator I don’t think it’s acceptable to bar anyone from responding to a topic. A member posting here always has the option of not responding to a comment, for any reason.

If a post is considered to be unacceptable, for any reason whatsoever, please report it, with a reason, and a moderator will review the content.

In this particular instance I can’t judge the technical aspect of tulamide’s post but it may be useful to others following the subject.

As I’ve come to say lately, let’s keep it sweet guys!

Spogg, as a moderator - should you interfere at this point? Tricky question, isn't it?

Let say, that my motivation is a non-strict parallel to someone else who was recently pretty active on the forum.

I bet this thread is dead now.
