The SVG (Scalable Vector Graphics) format is a vector image which can be easily scaled to any size without losing its quality. It is becoming increasingly popular among web developers, graphic designers and animators due to its versatility and scalability. SVG is an XML-based vector image format and can be used to create animations. There are several properties related to SVG stroke which need to be understood in order to create an animation.
The stroke is an important element in SVG as it can be used to draw shapes and lines, as well as to create animations. The stroke is essentially a line drawn around the shape or outline of an SVG. It can be customized in various ways and there are a number of properties associated with it that can be used to create interesting animations. These properties include the stroke width, stroke color, stroke linecap, stroke dasharray, stroke dashoffset, stroke linejoin, and stroke opacity.
Stroke Width
The stroke width is the width of the line drawn around the shape or outline of the SVG. It is measured in pixels and can be set to any value between 0 (no line) and the maximum size of the SVG. It is important to note that if the stroke width is too large, it can cause the animation to become distorted or pixelated. The stroke width can be set using the “stroke-width” property.
Stroke Color
The stroke color is the color of the line drawn around the shape or outline of the SVG. It is specified using the “stroke” property and can be set to any color, including RGB values or hexadecimal values. It is important to note that the stroke color will be visible even if the stroke width is set to 0.
Stroke Linecap
The stroke linecap is the style of the line drawn around the shape or outline of the SVG. It is specified using the “stroke-linecap” property and can be set to one of three values: butt (default), round, or square. The linecap determines the style of the ends of the line, and the difference between the three values can be seen in the image below.
Stroke Dasharray
The stroke dasharray is used to create dashed lines, which can be used to create interesting animations. It is specified using the “stroke-dasharray” property and is a comma-separated list of lengths of alternating dashes and gaps. The length of the dashes and gaps can be any positive number, and the number of dashes and gaps can be any positive integer. If the list contains an odd number of values, then the last value will be repeated.
Stroke Dashoffset
The stroke dashoffset is used to specify the offset of the start of the dashed line. It is specified using the “stroke-dashoffset” property and is a positive number that is equal to the length of the dashes and gaps in the stroke dasharray. It is important to note that the stroke dashoffset must be equal to or less than the length of the dashes and gaps in the dasharray.
Stroke Linejoin
The stroke linejoin is the style of the joins between different parts of the stroke. It is specified using the “stroke-linejoin” property and can be set to one of three values: miter (default), round, or bevel. The linejoin determines the style of the joins between the different parts of the line, and the difference between the three values can be seen in the image below.
Stroke Opacity
The stroke opacity is the opacity of the line drawn around the shape or outline of the SVG. It is specified using the “stroke-opacity” property and can be set to any value between 0 (fully transparent) and 1 (fully opaque). It is important to note that the stroke opacity will be visible even if the stroke width is set to 0.
These are the SVG stroke properties that are necessary to create an animated SVG. Understanding how these properties work and how they can be used to create animations is essential for creating dynamic and engaging animations. With the right knowledge and practice, you can create stunning animations with SVG.
