Hello, Mr. Sch?fer!

Thank you for your valuable information about the great Gutemberg. 

I'm learning Python too, and made a Scribus Script that do the job you want. 


The kernel logic is:

ratio = oStyle.Height / oStyle.Width REM Sqr(2.0)


pageWidth, pageHeight = scribus.getPageSize()
ratio = pageHeight / pageWidth 

oStyle.TopMargin = oStyle.LeftMargin * ratio
> oStyle.RightMargin = oStyle.LeftMargin * 2
> oStyle.BottomMargin = oStyle.RightMargin * ratio


topMargin, leftMargin, rightMargin, bottomMargin = scribus.getPageMargins()
topMargin = leftMargin * ratio
rightMargin = leftMargin * 2
bottomMargin = rightMargin * ratio

The complete script:

------------------------------
#!/usr/bin/env python2.3
# -*- coding: utf-8 -*-
"""Generate margins according Gutemberg way.
"""
import sys

"""Locale strings to be translated """
TITLE = "Generate margins"
noDocMsg = "<h2>First, open a doc</h2>This script only work on opened 
document. <b>Open a document</b> before run this script." 
runningMsg = "Running script..." 
noScribusMsg = "This Python script is written for the Scribus scripting 
interface.\nIt can only be run from within Scribus."

try:
import scribus
except ImportError,err:
print noScribusMsg
sys.exit(1)

from scribus import UNIT_POINTS,BUTTON_OK,ICON_WARNING

def main(argv):
"""Generate guides"""
if scribus.haveDoc():
scribus.setRedraw(False)
unit = scribus.getUnit() # save original unit
scribus.setUnit(UNIT_POINTS) # working in points, due a bug in 
getPageMargins

pageWidth, pageHeight = scribus.getPageSize()
ratio = pageHeight / pageWidth
topMargin, leftMargin, rightMargin, bottomMargin = scribus.getPageMargins()
topMargin = leftMargin * ratio
rightMargin = leftMargin * 2
bottomMargin = rightMargin * ratio
scribus.setMargins(leftMargin, rightMargin, topMargin, bottomMargin)

scribus.setUnit(unit) # restore original unit

else:
scribus.messageBox(TITLE, noDocMsg, ICON_WARNING, BUTTON_OK)

def main_wrapper(argv):
try:
scribus.statusMessage(runningMsg)
scribus.progressReset()
main(argv)
finally:
if scribus.haveDoc():
scribus.setRedraw(True)
scribus.statusMessage("")
scribus.progressReset()

if __name__ == '__main__':
main_wrapper(sys.argv)
