What is an SVG Polygon?
An SVG polygon is a two-dimensional shape that is created using straight lines. It is defined by a set of points and the lines between them. It is used to create various shapes, such as triangles, squares, and pentagons. In this tutorial, we will be learning how to create a polygon using SVG.
Creating the SVG Polygon
To create a polygon using SVG, we need to use the
Defining the Points
To define the points for the polygon, we need to specify the number of points and the x- and y-coordinates of each point. The coordinates are specified in a comma-separated list. For example, to create a triangle, we would specify three points with the following coordinates: (x1, y1), (x2, y2), and (x3, y3). This would create a triangle with the three points at the given coordinates.
Setting the Color
To set the color of the polygon, we need to use the fill attribute. This attribute specifies the color of the shape. The default value is black, but we can specify any color we want, either as a hex code (e.g., #FF0000 for red) or as a color name (e.g., blue).
Setting the Opacity
The opacity of the shape can be set using the opacity attribute. This attribute is used to set the transparency of the shape. The default value is 1, which is the same as fully opaque. To set the shape to be partially transparent, we can set the value to any number between 0 and 1. For example, a value of 0.5 would set the shape to be 50% transparent.
Setting the Stroke Width
The stroke width of the shape can be set using the stroke-width attribute. This attribute is used to set the width of the stroke (or line) around the shape. The default value is 1, which is the same as 1 pixel. To set the stroke to be thicker or thinner, we can set the value to any number between 0 and infinity.
Setting the Stroke Color
The stroke color of the shape can be set using the stroke attribute. This attribute is used to set the color of the stroke (or line) around the shape. The default value is black, but we can specify any color we want, either as a hex code (e.g., #FF0000 for red) or as a color name (e.g., blue).
Setting the Stroke Opacity
The opacity of the stroke can be set using the stroke-opacity attribute. This attribute is used to set the transparency of the stroke (or line) around the shape. The default value is 1, which is the same as fully opaque. To set the stroke to be partially transparent, we can set the value to any number between 0 and 1. For example, a value of 0.5 would set the stroke to be 50% transparent.
Example
Let’s look at an example of how to create a polygon using SVG. In this example, we will create a triangle with the following coordinates: (x1, y1), (x2, y2) and (x3, y3). We will also set the color of the triangle to red and the stroke width to 3 pixels.
Conclusion
In this tutorial, we have learned how to create a polygon using SVG. We have seen how to define the points of the polygon, how to set the color, opacity, stroke width, and stroke color of the shape, and we have also seen an example of how to create a triangle. By following the steps outlined in this tutorial, you should now be able to create any polygon you want using SVG.
