Library Version

💡 You can also check the current PptxGenJS library version using the read-only version property

console.log(pptx.version); // e.g. "4.0.0"

Metadata Properties Examples

PptxGenJS uses ES6-style getters/setters.

pptx.title = 'My Awesome Presentation';
pptx.author = 'Brent Ely';
pptx.subject = 'Annual Report';
pptx.company = 'Computer Science Chair';
pptx.revision = '15';

Slide Layouts (Sizes)

Layout option applies to all slides in the current Presentation.

Slide Layout Syntax

pptx.layout = 'LAYOUT_NAME';

Standard Slide Layouts

Layout Name	Default	Layout Slide Size
LAYOUT_16x9	Yes	10 x 5.625 inches
LAYOUT_16x10	No	10 x 6.25 inches
LAYOUT_4x3	No	10 x 7.5 inches
LAYOUT_WIDE	No	13.3 x 7.5 inches

Custom Slide Layouts

You can create custom layouts of any size!

• Use the defineLayout() method to create any size custom layout
• Multiple layouts are supported. E.g.: create an ‘A3’ and ‘A4’, then use as desired

Custom Slide Layout Example

// Define new layout for the Presentation
pptx.defineLayout({ name:'A3', width:16.5, height:11.7 });

// Set presentation to use new layout
pptx.layout = 'A3';

🔍 Need to inspect the current layout size?

console.log(pptx.presLayout); // { width: 10, height: 5.625 }

Text Direction

Text Direction Options

Right-to-Left (RTL) text is supported. Simply set the RTL mode presentation property.

Text Direction Examples

pptx.rtlMode = true; // set RTL text mode to true
pptx.theme = { lang: "he" }; // set RTL language to use (default is 'EN-US')

Notes:

• You may also need to set an RTL lang value such as lang='he' as the default lang is ‘EN-US’
• See Issue#600 for more

Default Font

Default Font Options

Use the headFontFace and bodyFontFace properties to set the default font used in the presentation.

Default Font Examples

pptx.theme = { headFontFace: "Arial Light" };
pptx.theme = { bodyFontFace: "Arial" };
