Hi, Wolfgang,
I am reading a book desinged by Springer-Verlag, whose size if 152mm X 226mm. Its backspace is 25mm, width 107mm, topspace 20mm, height 181 mm, this is the global layout. And the page number lies in the header, but no footers.
The chapter page in this book has a different layout, whose footer in not empty and the page number of the chapter page is in the footer. the height is 191mm, footer \lineheight(=\baselineskip?), footerdistance \lineheight. Other keys are the same with the global layout.
If I want to achieve the layouts like this book, do I need the two layouts in my codes? In my view, I need them, but I don't know if there is a better method.
