Implementation

import SvgAnnotator from "svg-annotator";

You need to place a single element inside the SvgAnnotator (div, section, svg or canvas), as the SvgAnnotator will base its size upon the first slotted element. This element and all its children will be part of the annotation area.

If your content contains multiple elements, place them inside a single div, section, svg or canvas element:

<SvgAnnotator>
    <div>
        ... any content you want
    </div>
</SvgAnnotator>

<SvgAnnotator>
    <section>
        ... any content you want
    </section>
</SvgAnnotator>

<SvgAnnotator>
    <svg>
        ... any content you want
    </svg>
</SvgAnnotator>

<SvgAnnotator>
    <canvas>
    </canvas>
</SvgAnnotator>

Props

Events

@toggleOpenState returns true if the toolbar is open, and false if it is closed.

@interface exposes methods to the parent (since version 0.3.7) See full documentation for an implementation example.

Caveats

• Moving a shape too quickly can make the pointer leave the current shape and focus on another shape.
• While the menu is open, the drawing area is above the content that was placed in the slot. User interaction with the slotted content is not possible, as all interactions will concern the SvgAnnotator.
• During the pdf generation, all fonts will be converted to 'Helvetica', which is one of the default fonts supported by jspdf. Not providing your font in the prop 'fontFamily' will cause content to remain with 'Helvetica' after the pdf generation resumes.
