Lazur - OK I think that helped most my query. The painting part is much simpler. I want to design - practically the perfect final image; and I love the fact that it's possible to do perfectly\mathematically etc. Then I'll just print the most general lines\points - only to not have to find them again...

Lazur - thank you for the post. I'll read on the Bézier-Curves. What I plan to do with the program - is to design paintings, and then to print only the outlines\points and to paint in analog\traditional means, according to the design. So if I understood the concepts correctly: I can use the square-g...

I would like to know some general mathematics behind a shape, curve, node, shade, color-gradient etc.
Anyway, thank you.

D'oh!! I knew I missed it, and it's somewhere in front of me; looked all over for it. It was collapsed though; which maybe removes a few points of noobness for me.

Thanks.

In the tutorial - it says "The Tweak Tool in a color mode has four options. It can act independently on a color's hue, saturation, lightness (HSL) and opacity". It doesn't say - where they are; and I can't find them. (the tutorial page - http://tavmjong.free.fr/INKSCAPE/MANUAL/html/Tweak-C...

Specifically - the first question I thought of - is whether the basic shapes are lighter than if I'll turn them to paths. Meaning - that they require less information, and lighter on the program\rendering. So if I'll create a very complex "painting" - maybe I should try to use most basic s...
