The Tools of the Trade

A robust annotation system with a set of easy-to-use tools will make your app the stalwart of document handling in any business environment.

Toolbar

The annotation toolbar enables quick access to all the annotation types in the PDF spec. It’s fully customizable, and it even supports predefined pen tool settings for seamless switching between visual annotation styles.

Guides

Note

Note annotations let you add longer comments to PDF documents. You can also select a custom icon shape and color for the note through the custom note inspector.

Guides

Ink

With ink annotations, you can add predefined shapes and create freeform drawings on a PDF document. Color and line thickness are easily adjustable via the annotation inspector in the toolbar.

Guides

Text

Add new text directly to the page, and take advantage of many convenient features, like automatic annotation sizing, copy and paste, text rotation, custom font selection, justification, and callout annotations.

Guides

Inspector

The context-sensitive annotation inspector provides fine-grained control over how annotations look — from border and fill colors, to opacity and font settings.

Guides

Rotation

PSPDFKit supports rotation for stamp and free text annotations, which allows your users to freely rotate selected annotations. You can also change the rotation of annotations through the API.
