What's this?

This plugin is added to the menu Effects, submenu Render.

You could create multiple kind of Roses (Rosaces in French).

Wiki link: http://en.wikipedia.org/wiki/Rose_%28mathematics%29

I found the formulas here (French)

http://www.mathcurve.com/courbes2d/hypotrochoid/hypotrochoid.shtml

This is where I got the Q,A,K factors...

 

 

Download it!

Plugin Rosaces.dll

How to install

Close Paint.net

 

Classic version of Paint.net

Unzip and (re)place the DLL in your Effect folder usually: C:/Program Files/Paint.NET/Effects

 

Microsoft Store version of Paint.net

Unzip and (re)place the DLL in your Effect folder usually: /My Documents/paint.net App Files/Effects/

You have to adapt for your language My Documents

 

 

The User interface

Q factor:

the curve will be rose shaped with

.. 2 x Q petals if Q is even, and

.. 1 x Q petals if Q is odd.

if Q > 0 the petals are outside

if Q < 0 the petals are inside

With Q=2 you obtain an ellipse.

A factor:

A is the radius of the base circle and it is useless if the option 'Fit the image..' is checked.

Uncheck the option 'Fit the image..' and choose the size with this slider.

K factor:

K plays on the distance from the center to the inner curves. If you increase this value, you could have a kind of ring.

Special values:

K = 1 : No petal, just pikes.

K = Q - 1 : you have a rose (each curve goes through the center)

Quantity of vertex:

You set here how many points should draw the curves.

Steps:

You could increase the step of the points to link together.

Angle:

You could rotate the figure to draw.

Color:

The primary color is the default color (the first time). You could choose another color...

Variable color:

:Warning: Each line uses a different color. It increases the process time!

0 for fixed color (for the color wheel), 1 or > to set the number of cycle...

Transparency:

...and another level of transparency.

Brush width:

Set the width of the lines to draw.

Fit the image size:

As all the points are pre-calculated, you could choose to reduce/enlarge to make the figure fit the image.

The scale is the same for vertical and horizontal.

Anti-Aliasing:

As it says!

Some tips:

Set the brush width to 1 and the transparency to 30.

Try the steps = 1/2 Quantity of vertex - 1

Wow. How long did some of those more intricate ones take to render?

EDIT: How about a random seed button?

 

The Doctor: There was a goblin, or a trickster, or a warrior... A nameless, terrible thing, soaked in the blood of a billion galaxies. The most feared being in all the cosmos. And nothing could stop it, or hold it, or reason with it. One day it would just drop out of the sky and tear down your world.
Amy: But how did it end up in there?
The Doctor: You know fairy tales. A good wizard tricked it.
River Song: I hate good wizards in fairy tales; they always turn out to be him.

Looks great! I cannot wait until I get home to try this one out. Quick question: Is this a render, or does it distort the image? (I cant try it out, so I am sorry)
What's this?

This is a plugin under Effect/Render.

:roll:

What would I ever do without Pyro's wry sense of sarcasm and humor. :)

There is no bread in my sarcasm!

Nor vodka.
