Sorting list of Bounding boxes

Arava,

setof doesn't sort anything (nor ever has done). There's no switch or problem with the Virtuoso version because this is not what setof is supposed to do. All setof does is return the members of a list that match a condition.

Perhaps you should post your code so that we know what you're talking about? I could give you code to do the sorting, but given your misunderstanding about setof, I'd like to be clear about what it's expecting.

Thanks Andrew.

sorry its order of shapes not bBoxes, (actually procedure works on bBox of  OUTLINEs).

outlineLpp=list("OUTLINE" "drawing")
outlines = setof(obj cvId~>shapes obj~>lpp == outlineLpp)
OL_bBox=outlines~>bBox

Arava.

So which do you want sorted, the variable outlines or the variable OL_bBox?

Andrew

Finally OL_bBox must be a list of bBoxes order from BottomLeft to TopRight

Arava

procedure(CCFcompareBBoxes(bb1 bb2)
  let((ll1 ll2)
    ll1=lowerLeft(bb1)
    ll2=lowerLeft(bb2)
    if(xCoord(ll1)==xCoord(ll2) then
      yCoord(ll1)<yCoord(ll2)
    else
      xCoord(ll1)<xCoord(ll2)
    )
  )
)

OL_bBox=sort(outlines~>bBox 'CCFcompareBBoxes)

This sorts based on the lower left of the bBox, by x coordinate first, then y. If you need a different order (BottomLeft to TopRight is ambiguous in your description), then it's easy enough to change the code - the comparison function returns t if the first bounding box is "less" than the second, and you can define what you mean by "less".

Regards,

Andrew.

Thank you so much Andrew

This works perfectly!!!
