I'd like to generate an odf file with odfpy, and am stuck on underlining text. Here is a minimal example inspired from official documentation, where i can't find any information about what attributes can be used and where. Any suggestion?
from odf.opendocument import OpenDocumentText
from odf.style import Style, TextProperties
from odf.text import H, P, Span
textdoc = OpenDocumentText()
ustyle = Style(name="Underline", family="text")
#uprop = TextProperties(fontweight="bold") #uncommented, this works well
#uprop = TextProperties(attributes={"fontsize":"26pt"}) #this either
uprop = TextProperties(attributes={"underline":"solid"}) # bad guess, wont work !!
ustyle.addElement(uprop)
textdoc.automaticstyles.addElement(ustyle)
p = P(text="Hello world. ")
underlinedpart = Span(stylename=ustyle, text="This part would like to be underlined. ")
p.addElement(underlinedpart)
p.addText("This is after the style test.")
textdoc.text.addElement(p)
textdoc.save("myfirstdocument.odt")
Here is how I finally got it:
I created a sample document with underlining using libreoffice, and unzipped it. Looking in styles.xml part of the extracted files, I got the part that makes underlining in the document:
The interesting style attributes are named: text-underline-style, text-underline-width and text-underline-color.
To use them in odfpy, '-' characters must be removed, and attributes keys must be used as str (with quotes) like in the following code. A correct style family (text in our case) must be specified in the Style constructor call.
