Adjusting the frame horizontally

It's easy to do for a one-line frame. But what use cases do *you* see for an horizontal automatic correction?

"ein Text hat, anders als ein Bild keine Dimensionen. Wenn man ihn automatisch anpassen will, muß man die Schrift, die Schriftgröße, ggf. andere Einstellungen wie Silbentrennung, Kerning, Randausgleich berücksichtigen. Das mindeste,was man tun muß, ist, dem Anwender die Wahl zu lassen, in welche Richtung der Textrahmen angepaßt werden soll"

import a text at the right size

• read a text file
• filter it line by line
• put it in a frame
• fit the height of the frame to the length of its content

#!/usr/bin/env python
import sys
try:
   import scribus
except ImportError:
   print "This script only works from within Scribus"
   sys.exit(1)


# read the content of the file line by line into the text frame
file_name = 'mytext.txt'
file_name = 'abc.txt'
file = open(file_name, 'r')

text = "";

for line in open(file_name, 'r') :
    if line != '\n':
        # put here some text handling/filtering
        text += unicode(line, 'iso-8859-2')

# create a text frame and put the text into it
x = 60
y = 100
w = 300
h = 10

frame = scribus.createText(x, y, w, h)
scribus.setText(text, frame)

# resize the frame in 10pt steps
while (scribus.textOverflows(frame) > 0) :
    h += 10
    scribus.sizeObject(w, h, frame)

# undo the latest 10pt step and fine adjust in 1pt steps
h -= 10
scribus.sizeObject(w, h, frame)

while (scribus.textOverflows(frame) > 0) :
    h += 1
    scribus.sizeObject(w, h, frame)
