<h2>Use a WebGL drawer implementation (using three.js) instead of the default context2d drawer</h2>

<div class="mirrored">

<div class="description">
|
|
The context2d drawing operations in core OpenSeadragon have been
|
|
consolidated from the <pre>TiledImage</pre> and <pre>Tile</pre> classes into the
|
|
<pre>Drawer</pre> class, which inherits from a new <pre>DrawerBase</pre> base class.
|
|
The <pre>TiledImage</pre> and <pre>Tile</pre> classes now handle the logic of managing
|
|
tile positioning and image data, with cleaner separation from details of the rendering
|
|
process. <pre>DrawerBase</pre> defines a public API that core OpenSeadragon code uses to
|
|
interact with the drawer implementation. To use a custom drawer/render, define
|
|
a new class that inherits from <pre>DrawerBase</pre> and implements the public API.
|
|
The constructor of this class can be passed in during construction of the viewer using the
|
|
new <pre>customDrawer</pre> option.
