I need a script for converting POLYGON to Rects.
I already have a script which converts rect/polygons to path in layout. But this works for only few sets of polygons only (simple polygons-non branched).
The code I need now is where the input will be the id of a polygon and the o/p should be rects
Ex i/p to proc - cvid~>objType - "polygon"
cvid~>points or the cvid itself.
o/p from proc - list of rects (bBox's) i.e
Please give a code or an Alogrithm that works.
Thanks & Best Regards,
dbLayerTile() will take a list of shapes and generate a new list of shapes which are trapezoids (if the original shapes are all orthogonal, the resulting shapes will be rectangles).So that does what you want.Regards,Andrew.
Thanks very very much Andrew. There is one saying in Telugu "sankalo pilladini pettukoni ooranta vetikadanta" which means"The baby is right in ur lap and u are searching the entire city". Its the same here. Can u tell me what u mean by "if the original shapes are all orthogonal" ( any images )Any ways dbLayerTile is working well for all types of polygons in the layout I have.Thanks,Sathya.
I've attached a picture. By orthogonal I mean that all the angles are multiples of 90 degrees. As you can see in this example, some of the angles are not 90 degrees, and so those parts have been tiled into trapezoids rather than rectangles (well, a rectangle is a trapezoid, but you know what I mean).If your shapes only have 90 degree multiples in the angles, you'll get rectangles out.Regards,Andrew.
Ok got it. ThanksNot greedy but dbLayerTile needs a layer name as input so that it can create rectangles over the object I gave.Is there any other command which will return only rectangles (ids or bBox's) rather than creating them and returning their idsOfcourse I can get the bBox and delete those created layers. Still if there is any other command....Thanks,Sathya
Hi Sathya,Well, it already does return rectangles - (ids). You can't return a rectangle dbId without creating it. database ids have to be in the database!If you're wanting a function which just returns the bBoxes of the resulting rectangles rather than actually creating them, then no such function exists (not built in anyway),It's not exactly difficult though:bBoxList=foreach(mapcar shape dbLayerTile(cvId list("layer" "purpose") srcShapes) prog1(shape~>bBox dbDeleteObject(shape)))Regards,Andrew.
