- use large images with smooth lines (SVG is vector graphics)
- edit size, position, shape or colors of images (easy to change)
- clip, mask or filter images (SVG supports these features)
- user interactive objects (DOM events can be added to SVG elements)
To demonstrate these advantages of SVG, Mozilla Japan has made a practical web application with SVG. “Foxkeh’s Wallpaper Creator” is a tool that allows you to easily create your own wallpaper in your browser. Not only can you choose Foxkeh and background image, you can easily change the size, position and transparency of Foxkeh and calender image.
I believe this application is enough easy to use and no more explanation is needed.
Just try creating wallpaper and realize how SVG is useful for web applications!
