Dojo SVG (Scalable Vector Graphics) is a powerful tool for creating designs that can be used in a variety of ways. It is a great way to create designs that can be used in webpages, applications, and even printed media. The Dojo SVG library provides a set of tools to make creating and manipulating vector graphics easier.

One of the most common uses of Dojo SVG is to create a rect. A rect is a basic shape that can be used in a variety of ways. It is a great way to create simple shapes to use in a design. In this article, we will look at how to create a rect in Dojo SVG.

1. Create a New SVG Element

The first step in creating a rect in Dojo SVG is to create a new SVG element. This element will be the container for the rect. To create the element, use the createElementNS() method. This method takes two arguments: the namespace and the SVG element type. The namespace should be set to “http://www.w3.org/2000/svg” and the element type should be set to “svg”.

The createElementNS() method returns a reference to the new SVG element. This reference can then be used to set properties and add child elements. For example, the following code creates a new SVG element and sets its width and height:

var svg = document.createElementNS("http://www.w3.org/2000/svg", "svg"); svg.setAttribute("width", 500); svg.setAttribute("height", 500); 

2. Create a Rect Element

The next step is to create a rect element. To create the rect element, use the createElementNS() method again. This time, the namespace should be set to “http://www.w3.org/2000/svg” and the element type should be set to “rect”.

The createElementNS() method returns a reference to the new rect element. This reference can then be used to set properties and add child elements. For example, the following code creates a new rect element and sets its width and height:

var rect = document.createElementNS("http://www.w3.org/2000/svg", "rect"); rect.setAttribute("width", 100); rect.setAttribute("height", 100); 

3. Set Other Properties

The rect element also supports several other properties. These properties can be used to change the appearance of the rect. For example, the following code sets the x and y coordinates, the fill color, and the stroke width:

rect.setAttribute("x", 50); rect.setAttribute("y", 50); rect.setAttribute("fill", "#000000"); rect.setAttribute("stroke-width", 2); 

4. Add the Rect Element to the SVG Element

Once the rect element has been created and its properties have been set, it can be added to the SVG element. To do this, use the appendChild() method. This method takes a single argument: the element to be added. For example, the following code adds the rect element to the SVG element:

svg.appendChild(rect); 

5. Add the SVG Element to the Document

The last step is to add the SVG element to the document. To do this, use the appendChild() method again. This time, the argument should be the SVG element. For example, the following code adds the SVG element to the document:

document.body.appendChild(svg); 

Conclusion

Creating a rect in Dojo SVG is a fairly simple process. It involves creating a new SVG element, creating a rect element, setting properties, and adding the rect element to the SVG element. Once this is done, the SVG element can be added to the document and the rect will be displayed.

Dojo SVG is a powerful tool for creating designs. By learning how to create a rect in Dojo SVG, you can create simple shapes that can be used in a variety of ways.
