How to resize an SVG image?

Files in format .png or .jpg are easy to resize and in most cases, you do not need to use any special software to do it.
The resizing is more complicated when you want to change the size for .svg format files.

resize SVG files

What is making the .svg different from other image formats?

There can be a lot of confusion about which kind of image format to use to achieve the best result in any given situation.

In the case of .jpg and .png formats, the size of the image depends on the number of pixels. The image resolution is therefore defined by the number of pixels that defined the height and width of an image.

The .svg is a vector-based image format. SVG defines the graphics in XML format. A vector image uses geometric forms such as points, lines, curves, and shapes to represent different parts of the image as discrete objects. This is why they retain their high quality no matter how much you scale them (more about the .svg file you can read here).

How to resize a SVG image?

SVG images can be created and edited with any text editor but it is often more convenient to create SVG images with a drawing program, like Illustrator, Sketch, Inkscape, or another vector-based program.

I am using two ways to resize .svg files by using the text editor (you can use any text editor to resize your image).

Option 1:

When you will open the .svg file in the text editor it should show lines of code.

Example:

<svg width="100" height="100">
  <circle cx="50" cy="50" r="40" stroke="green" stroke-width="4" fill="yellow" />
</svg>

The width and height attributes of the element define the width and height of the SVG image. So you can change the width and height to what you want.

Option 2:

If you haven’t defined the width and the height of the image in the SVG code you can adjust the size in CSS:

svg {
  width:10%;
}

Example:

Hope this helps!

Round text animation on Scroll

Lately, I posted the SVG tutorial, how to move the text on the path (to see the tutorial click here), today I’ll show you another SVG text effect, how to move SVG text on the circle path by mouse scrolling.

animate a text on the circle

Animation:

*animation opened in the Safari browser.
*to see the live output of the animation on the website click here.

Demo:

What do you need to do?

  1. Add SVG
  2. Add CSS
  3. Add JavaScript

Step1.

Add SVG

Add an SVG shape (circle), and the text:

<svg id="tutorial" data-name="tutorial" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 144.48 144.48">
 
  <path class="shape" id="shape" d="M242.93,123A71.74,71.74,0,1,1,171.2,51.22,71.73,71.73,0,0,1,242.93,123Z" transform="translate(-98.96 -50.72)"/>

   <text font-family="arial" font-size="14" fill="black">
        <textPath xlink:href="#shape" startOffset="500px" id="textPath">Scroll to move a text on the circle.</textPath>
      
    </text>
</svg>

Step2.

Add CSS

Style the text and the circle:

body {
  height: 200vh;  
}

.shape {
  fill:none;
  stroke:#1d1d1b;
}

#tutorial {
  position: fixed;
  overflow: visible;
  width: 15%;
  left: 40%;
  top: 100px;
  transform: rotate(-150deg);
}

Step3.

Add JavaScript

const textPath = document.querySelector("#textPath");

const a = document.documentElement, 
      b = document.body,
      st = 'scrollTop',
      sh = 'scrollHeight';

document.addEventListener("scroll", event => {
  let percent = (a[st]||b[st]) / ((a[sh]||b[sh]) - a.clientHeight) * 100;
  textPath.setAttribute("startOffset", (-percent * 5) + 500)
});

*animation opened in the Safari browser.
*to see the animation on the website click here.

Demo:

Example2 – Moving text on a heart path:

*animation opened in the Safari browser.

Demo:

Step1.

Add a SVG path/ shape

In this tutorial we’ll create text on the circle (add a SVG path to the body section, to see more about the SVG path click here.):

<svg id="tutorial" data-name="tutorial" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 144.48 144.48">
 
  <path class="shape" id="shape" d="M242.93,123A71.74,71.74,0,1,1,171.2,51.22,71.73,71.73,0,0,1,242.93,123Z" transform="translate(-98.96 -50.72)"/>

Step2.

Add CSS/ Style the circle

.shape {
  fill:none;
  stroke:#1d1d1b;
}

#tutorial {
  position: relative;
  overflow: visible;
  width: 15%;
  left: 40%;
  top: 100px;
  transform: rotate(-120deg);
}

Step3.

Add the text( body section)

  <text font-family="arial" font-size="14" fill="black">
        <textPath xlink:href="#shape">SVG moving text on the circle.</textPath>

Step4.

SVG Stroke & Fill Animation

Some time ago we went through the tutorial SVG Path Drawing Animation, today we can go a bit further and learn how to fill our strokes.

SVG Fill Animation

Demo:

*to see the live output of the animation on the website click here.

Step1.

Add SVG

To create the animation you need to make sure that your SVG shape/path has a stroke. To see how to create basic shapes using SVG click here.

            fill-opacity: 0;
          }
          95% {

SVG Path Drawing Animation

Path Drawing Animation

The <path> element is used to define a path. It can draw anything you like!

Demo:

To see the live output of the animation on the website click here.

To create SVG Path Drawing Animation we’ll use the same SVG path from the tutorial – SVG Draw on Scroll (which I created in Adobe Illustrator).

Step1.

Add HTML

Get an SVG path (make sure that your shape has a stroke).

SVG Path drawing
<svg id="heart" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 348.43 311.23"><defs><style>.cls-1{fill:none;stroke:#be1622;stroke-miterlimit:10; }</style></defs><title>heart</title><path class="cls-1" d="M340.67,131.25c18.71-30.63,56.59-48.3,92.07-43s66.5,33.36,75.38,68.13c6.22,24.37,2.19,50.32-5.52,74.26-3.88,12.06-8.72,23.89-15.53,34.57s-15.51,20.05-24.35,29.15a861.3,861.3,0,0,1-120.45,103c-32.42-26.2-66.67-45.07-97.36-71.12-14.78-12.55-27.69-27.18-39.75-42.36-15.45-19.44-29.86-40.37-36.88-64.19-8.22-27.87-5.39-59.21,9.37-84.24C194.56,106.85,227,88,260.28,87.45s63.31,15.29,81.13,43.43Z" transform="translate(-163.24 -86.84)"/></svg>

Step2.

Add CSS

We will use the stroke-dasharray property for creating dashes in the stroke of SVG shapes, and also a stroke-dashoffset property to define the location along an SVG path where the dash of a stroke will begin.

body {
  background-color: #2a9d8f; 
  display: flex;
  justify-content: center;
  align-items: center;
  height: 100vh;
  
}

svg {
  width: 100%;
  max-width: 400px;
  padding: 150px;
  
}

.cls-1{
       stroke-width: 3px;
       stroke-dasharray: 1200;
       stroke-dashoffset: 1200;
       animation: draw 3s linear forwards infinite;
}

@keyframes draw {
  to {
    stroke-dashoffset: 0;
  }
}

SVG Draw on Scroll

SVG Draw on Scroll

Using SVG and JavaScript to draw a heart on scroll. Note that it has to be a <path> element:

Demo:

Step1.

Add HTML

Get a SVG path

To make this animation working it has to be a path (any other of SVG elements won’t work).

To create an animation I drew a path (heart) in Adobe Illustrator. To read more about SVG and learn how to create a SVG file click here and here.

<div class="container">
<div class="text"><h1>Scroll to draw</h1></div>
  
  
<svg id="heart" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 348.43 311.23"><defs><style>.heart{fill:none;stroke:#be1622;stroke-miterlimit:10; }</style></defs><title>heart</title><path id="heart1" class="heart" d="M340.67,131.25c18.71-30.63,56.59-48.3,92.07-43s66.5,33.36,75.38,68.13c6.22,24.37,2.19,50.32-5.52,74.26-3.88,12.06-8.72,23.89-15.53,34.57s-15.51,20.05-24.35,29.15a861.3,861.3,0,0,1-120.45,103c-32.42-26.2-66.67-45.07-97.36-71.12-14.78-12.55-27.69-27.18-39.75-42.36-15.45-19.44-29.86-40.37-36.88-64.19-8.22-27.87-5.39-59.21,9.37-84.24C194.56,106.85,227,88,260.28,87.45s63.31,15.29,81.13,43.43Z" transform="translate(-163.24 -86.84)"/></svg>
  
</div>

Step2.

Add CSS

body {
  background: linear-gradient(141deg, #f0f3bd 0%, #02c39a 51%, #00a896 75%);
  display: flex;
  justify-content: center;
  align-items: center;
  height: 5000px;
  
}

.container {
  position: relative; 
}

svg {
  stroke-width: 2px;
  position: fixed;
  width: 200px;
  height: auto;
  margin:0;
  top: 30%;
  left: 45%;
}

.text {
  position: absolute;
  top:-2500px;
  display: block;
  color: white;
  width:400px;
  left:-100px;
  text-shadow: 1px 1px 1px black;
}

Step3.

Add JavaScript

const svg = document.getElementById("heart1");
const length = svg.getTotalLength();


svg.style.strokeDasharray = length;

svg.style.strokeDashoffset = length;

window.addEventListener("scroll", function () {
  const scrollpercent = (document.body.scrollTop + document.documentElement.scrollTop) / (document.documentElement.scrollHeight - document.documentElement.clientHeight);

  const draw = length * scrollpercent;

  svg.style.strokeDashoffset = length - draw;

});

Enjoy coding!
