How to keep top level lable while flatten to bottom

zhisong

Dear,

Now I want to flat a layout, meanwhile I need to keep top level label and delete others in sub level.

Because I don't have edit permission for part of sub block, so I have to store top level label to variable, then flatten all block and delete all labels, at last restore top level label to original.

But how to store all label database?

Or any idea to keep these label? Thanks

-Jason

  • Jason,

    There's a CCR (I believe) for dbFlattenInst to be able to return a list of newly flattened objects, but in the absence of that enhancement, you could create a table using makeTable(), and then store the original labels as keys into the table. So something like this:

    labelTable=makeTable('labelTable nil)
    foreach(shape cv~>shapes
      when(shape~>objType=="label"
        labelTable[shape]=t
      )
    )
    dbFlattenInst(...)
    foreach(shape cv~>shapes
      when(shape~>objType=="label" && !labelTable[shape]
        dbDeleteObject(shape)
      )
    )
    ; clear the table so it can be garbage collected (no need to do this if labelTable is a local variable)
    labelTable=nil

    Please note I have not tested this - this is just typed in off the top of my head...

    Regards,

    Andrew.

  • Hi AB,

    I can't believe that I have forgotten && !labelTable  to filter obj to be deleted.

    Thanks for your informaion.

     PS, it should be !boundp(labelTable[shape])
