Create Open XML PowerPoint documents in Python

Hi,

I'm trying to do either: a) Have a table placeholder shape in my layout, and stuff a table into it - this doesn't seem to be possible as I can't set rows,cols etc on an existing table shape or b) Create a new table shape using the height,width,left,top etc from a placeholder shape in the layout. This seems to fail as the actual shape in the slide ends up with height,width,top,left all set to 0. The cloned placeholder shape seems to not copy these values into the local shape?

Example:

>>> for idx,ph in enumerate(ps.slidelayouts[3].shapes.placeholders):
...     print "id: %d name: %s height: %d sz: %r" % (idx, ph.name, ph.height, ph.sz)
... 
id: 0 name: Title 1 height: 747338 sz: 'full'
id: 1 name: Content Placeholder 2 height: 3098203 sz: 'half'
id: 2 name: Content Placeholder 3 height: 3098203 sz: 'half'
id: 3 name: Date Placeholder 4 height: 0 sz: 'half'
id: 4 name: Footer Placeholder 5 height: 0 sz: 'quarter'
id: 5 name: Slide Number Placeholder 6 height: 0 sz: 'quarter'
id: 6 name: Table Placeholder 8 height: 1045863 sz: 'quarter'
id: 7 name: Text Placeholder 10 height: 939800 sz: 'quarter'

>>> for idx,ph in enumerate(sld.shapes.placeholders):
...     print "id: %d name: %s height: %d sz: %r" % (idx, ph.name, ph.height, ph.sz)
... 
id: 0 name: Title 1 height: 0 sz: 'full'
id: 1 name: Content Placeholder 2 height: 0 sz: 'half'
id: 2 name: Content Placeholder 3 height: 0 sz: 'half'
id: 3 name: Table Placeholder 4 height: 0 sz: 'quarter'
id: 4 name: Text Placeholder 5 height: 0 sz: 'quarter'

which makes my attempt to copy those values fall flat.

Any ideas?

I saw issue 66 and thought I would contribute some debugging files.

I created a pptx from python-pptx and confirmed it wouldn't open in Keynote. Saved to another name in PowerPoint and this new file could be opened in Keynote. I installed opc-diag and generated the output.

github n00b, so now I need to figure out how to upload the files.

Hi Steve, this is an awesome library. I just started using it--apologies if my issue is simplistic or if I can find the answer elsewhere. I didn't see this in the docs or any previous issue--I am creating a pptx and serving it via Apache. I have the mimetype set to application/vnd.openxmlformats-officedocument.presentationml.presentation per one of your other issue comments. The file downloads fine from Chrome and FF, but when I open it, I get a "PowerPoint found a problem with content in the file...PowerPoint can attempt to repair the file. If you trust the source of this file, click Repair."

It's just a simple ppt with text and some images. Googling identifies a problem with "block / unblock" for Windows, but even after I unblock the file on Windows, PowerPoint still has an issue and wants to repair it (Mac and Windows 7 VM).

Have you seen this issue before? My Python code follows your examples. Thanks!

When I try to load a template I am getting this error. KeyError: "no content type 'image/x-wmf' in pptx.spec.pml_parttypes"

I added the following snippet to the "pml_parttypes" dictioanary in the "pptx/spec.py" file and it seems to fix the problem. Not sure if its the right fix.

'image/x-wmf': { 'basename' : 'image' , 'ext' : '.wmf' , 'name' : 'Image Part' , 'cardinality' : PTS_CARDINALITY_TUPLE , 'required' : False , 'baseURI' : '/ppt/media' , 'has_rels' : PTS_HASRELS_NEVER , 'rels_from' : ['handoutMaster', 'notesSlide', 'notesMaster', 'slide', 'slideLayout', 'slideMaster'] , 'reltype' : RT_IMAGE }

Hi PPTX Team I am trying to study pptx module to output presentation for CAE, but I can’t find an example for setting multi-axis. Do you have example for it? Thanks a lot For example: I want to set a chart and contain three vertical axis and one horizontal axis.

Code pres = Presentation('file.pptx')

Relevant Error: File "/usr/local/Cellar/python/3.7.3/Frameworks/Python.framework/Versions/3.7/lib/python3.7/zipfile.py", line 1428, in read with self.open(name, "r", pwd) as fp: File "/usr/local/Cellar/python/3.7.3/Frameworks/Python.framework/Versions/3.7/lib/python3.7/zipfile.py", line 1467, in open zinfo = self.getinfo(name) File "/usr/local/Cellar/python/3.7.3/Frameworks/Python.framework/Versions/3.7/lib/python3.7/zipfile.py", line 1395, in getinfo 'There is no item named %r in the archive' % name) KeyError: "There is no item named 'ppt/slides/NULL' in the archive"

I'd like to extract the text content from ppt slides following the document:

from pptx import Presentation

prs = Presentation('notes/lec02.ppt')

# text_runs will be populated with a list of strings,
# one for each text run in presentation
text_runs = []

for slide in prs.slides:
    for shape in slide.shapes:
        if not shape.has_textframe:
            continue
        for paragraph in shape.textframe.paragraphs:
            for run in paragraph.runs:
                text_runs.append(run.text)

But got such a weird error:

Did I do anything wrong? How should I deal with this issue? Thanks!

Within power point, under "paragraph", it is possible to set "Right-to-Left" text direction. How can it be done with python pptx? It isn't text alignment. Text alignment is something else. So if my presentation contains Hebrew then the text gets messed up. Thanks.

This seems to be a similar issue to the one described here: https://github.com/scanny/python-pptx/issues/174

I'm running a virtualenv with Python3.6. This is the error that I get when I see when I try to read in a powerpoint presentation using the ppt.Presentation() method:

  File "slidenator.py", line 309, in <module>

This used to work just fine in Python2. Not sure what the issue could be here. The solution described previously mentioned that there was some issue with argparse, but I'm unclear what that means.

When creating a pie chart, is it possible to add the category names as labels to the chart eliminating the need for the legend ?

chart.plots[0].has_data_labels = True data_labels = chart.plots[0].data_labels data_labels.number_format = '0%'

This puts the series values as labels. It would be nice if we can put the category values also.

I'm trying to add matplotlib plots to a PowerPoint. I have used this code on python-docx without issue. It doesn't seem to working for python-pptx.

This code doesn't work and gives error OSError: cannot identify image file <_io.BytesIO object at 0x00000000407A17D8> It works fine if I have the file saved to file system and use a string path

...
buf = io.BytesIO()
t = list(range(0, 10, 1))
plt.plot(t, t, 'r--', t, [x**2 for x in t], 'bs', t, [x**3 for x in t], 'g^')
plt.savefig(buf, format="png")

slide.placeholders[0].text = 'string1'
slide.placeholders[13].text = 'string2'
slide.placeholders[14].insert_picture(buf)

Using this code in python-docx has worked fine on the same machine

buff = io.BytesIO()
t = list(range(0, 10, 1))
plt.plot(t, t, 'r--', t, [x**2 for x in t], 'bs', t, [x**3 for x in t], 'g^')
plt.savefig(buff, format="png")
doc.add_picture(buff)

Am I misunderstanding something about the API?

I have first modified a template using Google Slide. The file was originally created by PowerPoint. I modified the layout of the (only) master. It appears that PowerPoint can read these after exporting from GSlide, but python-pptx will read some default layouts, but cannot identify/read the modified ones. To summup: GSlide Masters and Layouts are not read but a default master+layout is applied instead.

Hello, I've installed new version of python 3.11, and wanted to install pptx module, but it seams there is some issue which I' cant solve. Not sure if pptx is available also within the new version of python ?

I generate synthesized voice narrations for my slides and keep the text with time stamps, like so:

(1.526)The (1.651)conditional (2.308)statement (2.839)consists (3.433)of (3.526)the (3.62)word (3.948)if, (4.526)a (4.62)condition, (5.576)the (5.686)colon, (6.542)and (6.683)the (6.761)body, (7.505)which (7.755)consists (8.317)of (8.411)the (8.505)statements (9.176)that (9.317)will (9.442)be (9.645)executed (10.348)if (10.458)the (10.551)condition (11.098)holds.

Suppose I add a few words somewhere in the narration, which results in the timestamps being shifted. I want to be able to write a Python script to automatically shift the animation delays, so the animations would be synchronized with the modified narration.

Hence, I would like to request a feature that would allow me to access and modify animation delays from a Python script. Thank you for the consideration.
