SVG Shapes

SVG has some predefined shape elements that can be used and manipulated by developers:

The following chapters will explain each element, starting with the rect element.


The <rect> Tag

The <rect> tag is used to create a rectangle and variations of a rectangle shape.

To understand how this works, copy the following code into Notepad and save the file as "rect1.svg". Place the file in your Web directory:

<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" 
"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg width="100%" height="100%" version="1.1"
xmlns="http://www.w3.org/2000/svg">
<rect width="300" height="100"
style="fill:rgb(0,0,255);stroke-width:1;
stroke:rgb(0,0,0)"/>
</svg>

Let's look at another example that contains some new attributes:

<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" 
"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg width="100%" height="100%" version="1.1"
xmlns="http://www.w3.org/2000/svg">
<rect x="20" y="20" width="250" height="250"
style="fill:blue;stroke:pink;stroke-width:5;
fill-opacity:0.1;stroke-opacity:0.9"/>
</svg>

Define the opacity for the whole element:

<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" 
"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg width="100%" height="100%" version="1.1"
xmlns="http://www.w3.org/2000/svg">
<rect x="20" y="20" width="250" height="250"
style="fill:blue;stroke:pink;stroke-width:5;
opacity:0.9"/>
</svg>

Last example, create a rectangle with rounded corners:

<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" 
"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg width="100%" height="100%" version="1.1"
xmlns="http://www.w3.org/2000/svg">
<rect x="20" y="20" rx="20" ry="20" width="250"
height="100" style="fill:red;stroke:black;
stroke-width:5;opacity:0.5"/>
</svg>
