[pstricks] [pst-eucl] add some useful macros with examples, do you like them?

[廖雄飞]

The working progress on these conics macros:
1. standard ellipse
coding done, document done.
2. general rotation ellipse
coding done, document done.
3. standard parabola
coding done, document done.
4. general rotation parrabola
coding done, document not done.
5. standard inversion parrabola
coding done, document not done.
6. general rotattion inversion parrabola
coding done, document not done.
7. standard hyperbola
coding not done, document done.
8. general rotation hyperbola
coding not done, document not done.
9. standard inversion hyperbola
coding not done, document not done.
10. general rotattion inversion hyperbola
coding not done, document not done.

Maybe I will finish these in four weeks, please wait some time.

OK. I will test and use them on my local texlive environment. maybe I will add more macros in the future, 
such as some parabola, ecclipse and hyperbola commands in the eukleides:


• parabola(A, l)
Parabola of focus A and directrix l.
• parabola(A, x, a)
Parabola of center A, such that x equals the semifocal chord and a the measure of the angle
between the principal axis and the horizontal direction.
• ellipse(A, x, y, a)
Ellipse of center A, such that x equals the half of the major axis, y the half of the minor
axis and a the polar angle of the principal axis.
• hyperbola(A, x, y, a)
Hyperbola of center A, such that x equals the half of the real axis, y the half of the imaginary
axis and a the polar angle of the principal axis.
• translation(cc, u)
• reflection(cc, l)
• rotation(cc, A [, a])
Rotation of center A and angle a (default: 180 ◦ ).
• homothecy(cc, A, x)
Homothecy, i.e. expansion or dilation, of center A and ratio x.


After I work done, I will send it to the maillist.

I have updated the patch and add a new macro \pstCircleRotNode:

\pstCircleRotNode - create a new node on the Circle O whose RotAngle
was the given value.

I'll wait a week until you have created a final patch! I cannot provide a
new version on a daily base ... ;-)

However, the best way would be to create an own package pst-euclx
and upload it  by yourself to CTAN. Then you can modify it just as
you like
