Drawing paths??

[dasfaker]

Hi Atom

I’m interested in drawing paths. I’ve been looking at rawmaterialsoftware API and I think I got it, but I’m fighting with this:
strokePath (const Path &path, const PathStrokeType &strokeType, const AffineTransform &transform=AffineTransform::identity) const

Can you make a little example?

[atom]

drawPanelBg = function(canvas,g)
	g:fillAll (Colour(0xff0000ff))
	path		= Path()
	stroke 		= PathStrokeType(2.0, PathStrokeType.curved, PathStrokeType.rounded)
	transform	= AffineTransform()
	path:addRectangle (0, 50, 100, 100)
	path:addStar (Point (100.0, 0.0), 7, 30.0, 70.0, 0.1)
	path:addStar (Point (0.0, 100.0), 6, 40.0, 70.0, 0.1)
 	path:addEllipse (0.0, 0.0, 120.0, 90.0)
	g:strokePath (path, stroke, transform)
end

Many thanks

You give us a new toy to play with.

Yeah but i need to bind more classes to make it fully functional. Image handling would be a good idea, some drawables, SVG format for vector graphics (other image format too ofcourse). It’s all to come, it just takes time.

By now I just want to draw non-linear envelopes, so I have enough. But I’ve encounter a problem. Path’s coordinates deal with floating numbers and they don’t like an integer number (just what I get from a modulator value).

Is there any way to convert integers to floating numbers?

[dasfaker]

Forget what I just posted, there was a typo in my code.
It works fine with the value of a modulator.

yeah lua doesn’t have types.
