Make LibreOffice Draw Document to use odfpy

#odfpy #python3 #opendocument #odg

Odfpy is famous Python library to make OpenDocument Format.
But,How to use odfpy?

odfpy official manual is only api-for-odfpy.odt and example program in github.

OpenDocument Text and OpenDocument Spreadsheet's odfpy tutorial is a few found.
OpenDocument Graphic's odfpy tutorial is not found!

I want to have Getting started at Draw Document's odfpy.

Enviroment

  • Windows10 Pro/Home x64
  • Windows System for Linux(WSL)
  • Ubuntu16.04
  • Python3
  • Python3-pip (pip)
  • odfpy
  • iPython
  • LibreOffice Draw for Windows

I use WSL.
I don't explain to install WSL.
if don't install WSL, check it under url.

Install the Windows Subsystem for Linux

Setup Python 

$ sudo apt update
$ sudo apt upgrade
# Python
$ sudo apt install Python3
# pip
$ sudo apt Python3-pip
$ pip3 install -U pip -user
# odfpy iPython
$ pip3 install odfpy,iPython -user
$ pip3 list --format columns
# folder
$ mkdir odfpy
$ cd odfpy
Enter fullscreen mode Exit fullscreen mode

Make Document and Page

At first,I start iPython.
iPython is very useful.


$ ipython 
Python 3.6.3 (default, Nov  6 2017, 23:30:23) 
Type 'copyright', 'credits' or 'license' for more information
IPython 6.2.1 -- An enhanced Interactive Python. Type '?' for help.

In [1]:
Enter fullscreen mode Exit fullscreen mode

Check your current directory.
odfpy make Draw Document in this directory.
Put picture and python script to run.


# check your current directory
In [1]: %pwd
Out [1]:'/home/username/odfpy'
Enter fullscreen mode Exit fullscreen mode

Make docucment

In:[2] from odf.opendocument import OpenDocumentDrawing
In:[3] doc=Open # press your tab key
 open()          OpenDocumentDrawing()
Enter fullscreen mode Exit fullscreen mode

Type OpenDocu... press tab key.
Amazing! Type-Ahead.

OK?
Umm,drawing in addText method.
try,it.

In[3]:doc=OpenDocmentDrawing()
In[3]:doc.drawing.addText('aaaa')
....(Abbreviation)...
IllegalText: The <office:drawing> element does not allow text

In[4]:
Enter fullscreen mode Exit fullscreen mode

can't add Text.
Draw Document can't put direct text and Shape.
make Page.
Text and Shape in Page.

Open Another Terminal and make createpage.py file in odfpy folder.

from odf.opendocument import OpenDocumentDrawing
from odf.draw import Page
from odf.style import Style,MasterPage,PageLayout

## Create the drawing page style
dpstyle = Style(family="drawing-page",name="DP1")
doc.automaticstyles.addElement(dpstyle)

## Create page layout specifying dimensions
plstyle = PageLayout(name="PM1")
doc.automaticstyles.addElement(plstyle)

## Create a master page
masterpage = MasterPage(stylename=dpstyle, name="Default", pagelayoutname=plstyle)
doc.masterstyles.addElement(masterpage)

## Create a page to contain the drawing
drawpage = Page(masterpagename=masterpage, name="page1", stylename=dpstyle)
doc.drawing.addElement(drawpage)
Enter fullscreen mode Exit fullscreen mode

To make Page

  1. make PageStyle and PageLayout.
  2. make Masterpage
  3. make Page form MasterPage
  4. add Page to Draw Document

It's too much bother to make Page.
That’s how it is.

That run in iPython.

# check File
In[4]: %ls
createpage.py
In[5]: %run createpage.py
Enter fullscreen mode Exit fullscreen mode

If it is not error,Success to add Page.

PageProperties

How to change PageProperties?
I try a little.

# load PageLayoutProperties
In[6]:from odf.style import PageLayoutPropretis
In[7]:plsytle.addElement(PageProperties(margin="0cm",pageheight="210mm",pagewidth="297mm", printorientation="portrait"))
In[8]:doc.automaticstyles.addElement(plsytle)
Enter fullscreen mode Exit fullscreen mode

Nothing PaperSize,so we change pageheight and pagewidth.
and save it.

In[9]: doc.save('draw01',True)
Enter fullscreen mode Exit fullscreen mode

it copy to Windows Desktop.

$ cp draw01.odg /mnt/c/Users/username/Desktop
Enter fullscreen mode Exit fullscreen mode

open it on Windows to use LibreOffice Draw.

createpage.png

OK.

Add Text

It's too much bother to make Page for me.
So, it do.

In [1]:from odf.opendocument import OpenDocumentDrawing,load
In [2]:doc=load('draw01.odg')
In [3]:doc.getMediaType()
Out[3]: 'application/vnd.oasis.opendocument.graphics'
Enter fullscreen mode Exit fullscreen mode

load draw document.

To add Text,

  1. Make Text
  2. Make TextBox and add Text
  3. Make Frame and add TextBox
  4. Take out Page
  5. Add Frame to Page

Text can't directly add to Page.
To add Text,Text add to Frame or Rect...etc.

This is code underline.

In[4]: from odf.draw import Page,TextBox,Frame
# get Page
In[5]: page=doc.getElementByType(Page)
In[6]: page=page[0]
In[7]: from odf.text import P
# Create Text
In[8]: text=P()
In[9]: text.addText('こんにちは')
# Text add to TextBox
In[10]: tb=TextBox()
In[11]: tb.addElement(text)
# TextBox add to Frame.
# x,y is position.
In[12]: frame=Frame(width='100mm',height='20mm',x='2cm',y='2cm')
In[13]: frame.addElement(tb)
# Page add to Frame.
In[14]: page.addElement(frame)
# Save
In[15]: doc.save('draw02',True)
Enter fullscreen mode Exit fullscreen mode

LibreOffice Draw open draw02.odg.

addtext.png

good!
I want to change font size and background color.

TextProperties and GraphicProperties

TextProperties change Text's font-size.
GraphicProperties change Frame's background color.

In [1]: from odf.opendocument import load
In [2]: from odf.draw import Page,Frame,TextBox
In [3]: from odf.style import Style,TextProperties,GraphicProper
   ...: ties
In [4]: from odf.text import P
# load draw file
In [5]: doc=load('draw02.odg')
# Take out Frame and Text
In [6]: page=doc.getElementsByType(Page)
In [7]: page=page[0]
In [8]: frame=page.getElementsByType(Frame)
In [9]: frame=frame[0]
In [10]: tb=frame.getElementsByType(TextBox)
In [11]: tb=tb[0]
In [12]: text=tb.getElementsByType(P)
In [13]: text=text[0]
# make Style
In [14]: s=Style(name='P1',family='paragraph')
# English is fontsize But, Chinese Japanese Korean font is fontsizeasian.
# 「こんにちは」=fontasian
In [15]: tp=TextProperties(fontsize='32pt',fontsizeasian='32pt')
In [16]: gs=Style(name='GR1',family='graphic')
In [17]: gp=GraphicProperties(fill='none',stroke='none')
# add Style to Frame and Text
In [18]: text.setAttribute('stylename',s)
In [19]: frame.setAttribute('stylename',gs)
# add Style to Draw Document
In [20]: doc.automaticstyles.addElement(s)
In [21]: doc.automaticstyles.addElement(gs)
# Save
In [22]: doc.save('draw03',True)
Enter fullscreen mode Exit fullscreen mode

changestyle.png

got it!
Next,I want to add image.

add Image

Get Image

  1. Get LibreOffice Draw's icon png from Wikimedia Common.
  2. rename drawicon.png 
$ pwd
/home/users/odfpy

$ curl -O https://upload.wikimedia.org/wikipedia/commons/thumb/8/80/LibreOffice_4.0_Draw_Icon.svg/200px-LibreOffice_4.0_Draw_Icon.svg.png
$ mv 200px-LibreOffice_4.0_Draw_Icon.svg.png drawicon.png
$ ls drawicon.png
drawicon.png
Enter fullscreen mode Exit fullscreen mode

OK, I get image.

Add Image 

# load file.
In [1]: from odf.opendocument import load
In [2]: doc=load('draw01.odg')
# import need's Object
In [3]: from odf.draw import Page,Image,Frame
# Take out Page
In [4]: page=doc.getElementsByType(Page)
In [5]: page=page[0]
# make PhotoFrame. x,y is position,height width is size.
# This image is square,so height and width is same scale.
In [6]: photoframe=Frame(x='10mm',y='40mm',height='26mm',width='26mm')
# add Image to Draw Document.
In [7]: href=doc.addPicture('drawicon.png')
# add Image to photoframe
In [8]: photoframe.addElement(Image(href=href))
# add photoframe to Page
In [9]: page.addElement(photoframe)
# Save
In [10]: doc.save('draw04',True)
Enter fullscreen mode Exit fullscreen mode

Do you add Image to Document?
OK, Check Document.

  2. Put Text
  3. Put Image and Shape
  4. Save

Tahnks, Yusuke.

But I still didn't manage to get I want.

I am new to Python and I'm working with odt files, from libreoffice.

I would like to add an specific image to a specific position in my document.

By the way, I'm using the teletype method, from: balasankarc.in/tech/using-python-a....

I tried to paste some command lines in your guide and despite the programm runs ok, the archive doesn't add the image I want.

Thank you reading, sammarrques.

Your blog read a little.

It's a point that I concerned.

Writer and Draw is a little different.

When put picture on Writer Document,we need to think about Wrap text around a picture.

I read your blog a little more.
