I have a segment with some stacked layers. Simplified ASCII representation of the stacked view:
I want to ‘merge down’ (this is the term that GIMP uses for a similar operation) to
so that it becomes a single segment.
To obtain this, I have to split the XXXX lane, move the edges so that the upper part falls down, move the edges of the XXXX again to the edges of the YYYY and then join the segments.
While this works nicely it is a bit cumbersome when you have to do it often.
Is there a better (easier) way to perform this operation? A Lua script, maybe?
