This is a read-only archive of the inkscapeforum.com site. You can search for info here or post new questions and comments at I´m new here, and want to make an effort for write a plug in.
In my case the plug in is very similar to the Whirl.
The function is very different.
The effect in SciLab is like that:
Code: Select all
function [xf,yf]=revuelvo(x,y,a)
n=max(size(x));
xf=[],yf=[];
for i=1:n
r=sqrt(x(i)^2+y(i)^2);
alfa=a*atan(y(i),x(i));
xf(i)=r*cos(alfa);
yf(i)=r*sin(alfa);
end
endfunction
I want to rotate points in a factor "a" from a reference angle, without change the distance to the center. Is an angular expansion.
I have trouble with the paths and it´s representation.
I don't want to change the angles in the corners of the path. Only the nodes.
Where do you advise me to look for a good understanding of the codification and the way of modify the points?
Thanks
