Slides, notes and masters in a PPT file

Each slide, notes page and master is a top-level record, found through the persist directory from a SlidePersistAtom in one of the lists.

SlideContainer

Type 0x03EE. It holds a SlideAtom, optional slide show settings, the drawing (type 0x040C) with the slide’s shapes, a colour scheme and optional programmatic tags.

SlideAtom

Type 0x03EF, recVer 2, recLen 24.

Offset	Size	Field	Meaning
8	4	`geom`	A SlideLayoutType: the layout, as a hint.
12	8	`rgPlaceholderTypes`	Eight bytes of PlaceholderEnum, one for each placeholder.
20	4	`masterIdRef`	The master the slide follows, by slide identifier. Zero on a master.
24	4	`notesIdRef`	The slide’s notes page, or zero.
28	2	`slideFlags`	Bit 0: uses the master’s objects. Bit 1: its colour scheme. Bit 2: its background.
30	2	`unused`	Ignored.

geom	Layout	geom	Layout
0	Title slide	10	Column and two rows
1	Title and body (or a main master)	11	Two rows and column
2	Title master	13	Two columns and row
7	Title only	14	Four objects
8	Two columns	15	Big object
9	Two rows	16	Blank
17	Vertical title and body	18	Vertical title and two rows

Transitions

A SlideContainer can hold a SlideShowSlideInfoAtom (type 0x03F9, recLen 16) that sets the transition to the slide and how it advances.

Offset	Size	Field	Meaning
8	4	`slideTime`	Time on the slide in milliseconds, used with `fAutoAdvance`.
12	4	`soundIdRef`	The sound to play.
16	1	`effectDirection`	The variant of the effect.
17	1	`effectType`	The transition (table below).
18	2	flags	Bit 0 `fManualAdvance`, bit 2 `fHidden`, bit 4 `fSound`, bit 6 `fLoopSound`, bit 8 `fStopSound`, bit 10 `fAutoAdvance`, bit 12 `fCursorVisible`.
20	1	`speed`	0 is 0.75 seconds, 1 is 0.5 and 2 is 0.25.
21	3	`unused`	Ignored.

effectType	Transition	effectType	Transition
0	Cut	11	Box in or out
1	Random	13	Split
2	Blinds	17	Diamond
3	Checker	18	Plus
4	Cover	19	Wedge

Notes

A notes page is a NotesContainer (type 0x03F0) with a NotesAtom and a drawing. The text is on a placeholder whose PlaceholderAtom is PT_NotesBody, in the text records of that shape.

Offset	Size	Field	Meaning
8	4	`slideIdRef`	The slide these notes belong to, by slide identifier. Zero on the notes master.
12	2	`slideFlags`	What follows the notes master.
14	2	`unused`	Ignored.

A slide’s notesIdRef is matched against the slideId in the notes list’s SlidePersistAtoms, and a NotesAtom’s slideIdRef against a slide’s.

Masters and handouts

The master list holds a MainMasterContainer (type 0x03F8) for each main master, and a SlideContainer for each title master. A main master holds text styles, colour schemes and shapes that slides inherit. The notes master and the handout master are a NotesContainer and a HandoutContainer (type 0x0FC9), found through the two references in the DocumentAtom.

Placeholders

A placeholder shape has a PlaceholderAtom (type 0x0BC3, recLen 8) in its client data. The shape’s text style and position come from the master.

Offset	Size	Field	Meaning
8	4	`position`	An identifier for the placeholder. 0xFFFFFFFF means this shape is not one.
12	1	`placementId`	The kind of placeholder (table below).
13	1	`size`	The preferred size.
14	2	`unused`	Ignored.

Value	Kind	Value	Kind
