SVG

What is SVG?

SVG (Scalable Vector Graphics) is a vector image format.

Contrary to raster graphics or bit maps (an image represented by a rectangular grid of pixels) a vector image is a description of its geometric shapes, or drawing instructions, which the viewing

program will draw on the screen.

SVG Characteristics

SVG is:

  • scalable - zooms wont pixelate or degrade the image quality
  • text-based image format - like a webpage you can view and change the source code of an SVG image
  • editable in vector drawing software (Inkscape, Adobe Illustrator)
  • easily included within an HTML document
  • syntax similar to HTML

SVG: image and text

SVG elements

SVG in the browser

SVG styled by CSS

SVG with custom fonts

This is just the basics. We'll want to manipulate the SVG drawings further, not just style them with CSS, but:

  • add drawing elements,
  • remove them,
  • turn elements into links,
  • transform the image based on user interaction
  • create a new image every time a user visits the site,
  • etc.

To create those actions with need a scripting language for the browser.
