Freeform drawing with mouse

girig

Hi,

  Is it possible to draw freeform curves/shapes in virtuoso?

If not, any tricks that can make use of multiple piecewise "line" shapes tracking mouse movement?

I was able to get a crude piece of code working through enterPoints, but that can only track clicks, so the user has to click in short bursts close enough to get the desired shape. It would be ideal if a mouse-drag can be used to draw piecewise linear points tracking the cursor - amounting to a free-form shape.

procedure(addPt(win points)

 cv = deGetCellView(win)

 size = length(points)

 if(size>1 then

   pt1 = nthelem(size,points)

   pt2 = nthelem(size-1, points)

   dbCreateLine(cv list("text" "drawing") list(pt1 pt2))

  )

)

enterPoints(?prompts list("Enter Points") ?addPointProc "addPt" )

Thanks !
Giri.

    Andrew, Lawrence, 

     Thanks a bunch. This is really useful, sorry I had missed the updates towards linux support. I was able to invoke the stroke editor successfully. My original intent was to try and extract co-ordinates along the path of the gesture too (ceases to be a 'gesture' at that point and is more of a freeform shape), but this is definitely a good start and might cater to a good chunk of what I was looking for.

    Thanks once again!
