Can we automate the process of merging layers?

philyu

I follow such steps: Edit -> Layer -> Merge

Then I can merge layers.
However, I want to automate this process by using Macro Development. I'd like to know which class or procudure I should use.

Hello,

You can do that easily in the DRC environment (Macro Development > DRC):

https://www.klayout.de/doc-qt5/manual/drc_basic.html

https://www.klayout.de/doc-qt5/about/drc_ref_layer.html#h2-1534

layer.merge([overlap_count])

Cheers,

Tomas

@tomas2004 Thanks for the answer

I agree, but like to add you need to write it too ... so the above example equals to the DRC one-liner:

input(1, 0).merged.output(1, 0)

("merge" as a method will merge a copy of the layer, not the layer in the database).
