• Background• Shape Tree

• Tag List• Controls• Name

Masters

• Stored as separate parts ( one part per master ) in the package

• Serve to create consistency and expedite editing

Masters and Layouts

• Masters contain layouts– Each master is “primed” with a set of default

layouts– Layouts “contained” by relationship IDs

Layouts

Layouts ( pre-12 )

• Originally hard-coded mappings of placeholders on a slide surface– Determine location and types

of placeholders per slide– Approx 3 dozen in shipped

Layout Types

Layouts and Masters

• Title Placeholder information inherited from Slide Master

• Other “content” placeholders projected into Body Placeholder

True Layouts ( 12 )

• Now they are full-blown slides– Authors can create completely custom layouts– Smaller set is hard-coded for defaulting but

everything is editable– Stored as separate parts ( one part per

layout ) in the package• Title Masters now are Title Layouts

Layout Inheritance

• Continue to sit between slide master and slide• Each placeholder is a shape and can be edited

as such• Each placeholder now inherits from the slide

master by default– Title Placeholders inherit from Master Title

Placeholder– “Content” Placeholder inherit from Master Body

Placeholder ( excluding transforms )

Placeholders

Placeholders

• Serve four purposes– Prime slide surface– Encourage consistent formatting and

positioning– Act as entry points to functionality– Facilitate layout changes and template

applications• Primary means to opt-into cross-surface

inheritance

Placeholders

• Specialized instances of shapes done in client data– They are actual shapes on the slide surface– Placeholders cannot be grouped

Placeholder Size

• Some Placeholders are projected into Body Placeholder of the previous surface

• Size is a function of Body Placeholder size:– Full– Half– Quarter

Full Half Quarter

Placeholders

• Placeholders generally contain properties not content ( except for text )– Text not rendered on slides but is rendered on

masters and layouts• Instantiation of Placeholders “replaces”

with a new shape ( except for pictures )

Inheritance

• In general– The absence of data

implies inheritance– The absence of a

piece of data all the way through the model uses internal defaults ( where possible )

“Headers and Footers”

• Special set of placeholders– Header– Footer– Date / Time– Slide Number

• All implemented using placeholders as containing shape– Static variants resolve and flatten immediately– Dynamic variants use field codes to resolve

Fields

• Types specified by client• Referenced via GUID ( one GUID / field code )• No caching of last value• No intra-field editing

Field Types

• slidenum• datetime• datetime1• datetime2• datetime3• datetime4• datetime5• datetime6

• datetime7• datetime8• datetime9• datetime10• datetime11• datetime12• datetime13

Two Importance User Scenarios

Apply Layout

• Scenario: Switching layouts within a master

• Problem: Need to “match” placeholders

Apply Layout Algorithm

• Match on Placeholder function– For example, Title Title and Date/Time Date/Time– “Headers and Footers” will float if no match exists

here• Match on exact Placeholder type

– For example, Media Media and Body Body• Match on ability to consume

– For example, Text Object and SubTitle Text• Else, float ( idx = -1 )

Apply Design

• Scenario: Applying a new “design”• Problems

– Which layouts to bring in from new “design”– Which existing slides should be updated to

use the new layouts

Apply Design Algorithm

• Layout “equivalence” defined as– Layouts have the same number of

Placeholders ( not including “HF” Placeholders ), and

– Placeholders in both layouts are of the same type, and

– Layouts have the same name
