This is a read-only archive of the inkscapeforum.com site. You can search for info here or post new questions and comments at how can I get the pixel length of a text element in an extension? Is it possible to access the svg dom function "getComputedTextLength" ?
I found a python example here: http://wiki.inkscape.org/wiki/index.php ... ctTutorial
and added a msgbox command to show me some text information.
Could you please modify the last few lines of the following code to show the length of the text?
Code: Select all
#!/usr/bin/env python
# These two lines are only needed if you don't put the script directly into
# the installation directory
import sys
sys.path.append('C:\Program Files (x86)\Inkscape\share\extensions')
sys.path.append('C:\Python27')
