Notes Slide¶

A slide may have an associated notes page. The notes it contains are displayed under the slide in the PowerPoint UI when in edit mode. The slide notes are also shown in presenter mode, are displayed in Notes Pages view, and are printed on those notes pages.

Internally, a notes page is referred to as a notes slide. This is sensible because it is actually a specialized instance of a slide. It contains shapes, many of which are placeholders, and allows inserting of new shapes such as auto shapes, tables, and charts (although it is probably not common). Much of the functionality for a notes slide is inherited from existing base classes.

A notes slide is created using the notes master as a template. A presentation has no notes master when created from a template in PowerPoint. One is created according to a PowerPoint-internal preset default the first time it is needed, which is generally when a notes slide is created. It’s possible one can also be created by entering the Notes Master view and almost certainly is created by editing the master found there (haven’t tried it though). A presentation can have at most one notes master.

On creation, certain placeholders (slide image, notes, slide number) are copied from the notes master onto the new notes slide (if they have not been removed from the master). These “cloned” placeholders inherit position, size, and formatting from their corresponding notes master placeholder. If the position, size, or formatting of a notes slide placeholder is changed, the changed property is no long inherited (unchanged properties, however, continue to be inherited).

The remaining three placeholders that can appear on the notes master (date, header text, footer text) can optionally be made to appear on an individual notes slide using the Header and Footer… dialog. This dialog also has a button allowing all notes slides to be updated with the selected options. There appears to be some heuristic logic that automatically propagates these settings to notes for new slides as they are created.

A notes slide is not automatically created for each slide. Rather it is created the first time it is needed, perhaps most commonly when notes text is typed into the notes area under the slide in the UI.

Candidate Protocol¶

A notes slide is created on first access if one doesn’t exist. Consequently, Slide.has_notes_slide is provided to detect the presence of an existing notes slide, avoiding creation of unwanted notes slide objects:

>>> slide.has_notes_slide
False

Because a notes slide is created on first access, Slide.notes_slide unconditionally returns a NotesSlide object. Once created, the same instance is returned on each call:

>>> notes_slide = slide.notes_slide
>>> notes_slide
<pptx.notes.NotesSlide object at 0x10698c1e0>
>>> slide.has_notes_slide
True

Like any slide (slide, slide layout, slide master, etc.), a notes slide has shapes and placeholders, as well as other standard properties:

>>> notes_slide.shapes
<pptx.shapes.shapetree.NotesSlideShapes object at 0x10698c1e0>
>>> notes_slide.placeholders
<pptx.shapes.shapetree.NotesSlidePlaceholders object at 0x10698f622>

The distinctive characteristic of a notes slide is the notes it contains. These notes are contained in the text frame of the notes placeholder and are manipulated using the same properties and methods as any shape textframe:

>>> text_frame = notes_slide.notes_text_frame
>>> text_frame.text = 'foobar'
>>> text_frame.text
'foobar'
>>> text_frame.add_paragraph('barfoo')
>>> text_frame.text
'foobar\nbarfoo'

PowerPoint behavior¶

Notes page has its own view (View > Notes Page)
- Notes can be edited from there too
- It has a hide background graphics option and the other background settings
- Notes have richer edit capabilities (such as ruler for tabs and indents) in the Notes view.
A notes slide, once created, doesn’t disappear when its notes content is deleted.
NotesSlide placeholders inherit properties from the NotesMaster placeholder of the same type.
For some reason PowerPoint adds a second theme for the NotesMaster, not sure what that’s all about. I’ll just add the default theme2.xml, then folks can avoid that if they encounter problems just by pre-loading a notesMaster of their own in their template.

Example XML¶

Empty notes page element:
