Scalable Vector Graphics, hereafter referred to as SVG, is the least familiar components of web development. Its better knows siblings are HyperText Markup Language or HTML, Cascading Style Sheets or CSS and JavaScript
SVG can be used to create illustrations for a web page in exactly the same way that photographic images such as .JPG and .PNG are used. In some ways SVG images have some advantages over their photographic counterparts. These advantages are:
SVG files are very small and therefore load faster and take up less space
A small photographic image loses quality and becomes blurry if it is enlarged. On the other hand can be resized to any dimension without losing quality.
These two advantages should make it worth our while to becme familiar with this product.
The World Wide Web consortium began development of SVG in 1999 and Version 1 appeared in 2001. Further develpment occurred and the first draft of the second version appeared in 2018. The most recent draft was released in 2023.
SVG supports interactivity, animation and three types of graphical objects:
vector graphics
images
text
It can be styled using CSS and can use CSS for scripting. It can also be embedded in HTML. We shall give a brief description of each.
Path
A path is a compound shape drawn with straight lines and curves. It can be a shape in its own righ or can be used for clipping
Standard Shapes
These include the following:
paths
closed polygons
circles
ellipses
rectangles
round-cornered rectangles
Colours
Colours can be applied to all of the shapes mentioned above. SVG can use the rgb and rgba systems as well as the same colour constants that HTML recognises.
Clipping
This involves using a shape or combination of shapes to provide new outlines for other shapes. Yes, it is easier to work on an example of clipping than actually discussing it.
Interactivity
SVG images can respond to user's in many ways. This includes clicking or hovering with the mouse, getting or losing focus and keyboard keys.
Animation
SVG has inbuilt elements to control animation. This can be enhanced using JavaScript.
