SVG 导航器

Adds zooming and panning capabilities to SVG files

Note
——————————–
You can access file URLs by going to Chrome’s extension settings, and checking “Allow access to file URLs”

Usage
——————————–
Go to a website with an SVG file. The extension begins working on the SVG graphic and you may:
* Pan: click and drag or hold the space bar and drag the cursor to pan around the image
* Zoom in or out: use mouse scroll wheel
* Zoom: click and drag a zoom box of the desired area if enabled
* Zoom out: tap alt key
* Reset zoom: press escape
Trying to pan on an SVG by shift click and dragging currently causes undesirable panning; possibly a Google Chrome bug/feature.
If you want to view local files with this extension, you must enable “Allow access to file URLs” in Chrome’s Extensions view.
