Understanding SVG coordinate system

The initial user coordinate system is the coordinate system established on the SVG canvas. This coordinate system is initially identical to the viewport coordinate system—it has its origin at the top left corner of the viewport with the positive x-axis pointing towards the right, the positive y-axis pointing down.

How do SVG coordinates work?

In the SVG coordinate system the point x=0, y=0 is the upper left corner. The y-axis is thus reversed compared to a normal graph coordinate system. As y increases in SVG, the points, shapes etc. move down, not up.

How does viewBox work in SVG?

The viewbox attribute

1. It defines the aspect ratio of the image.
2. It defines how all the lengths and coordinates used inside the SVG should be scaled to fit the total space available.
3. It defines the origin of the SVG coordinate system, the point where x=0 and y=0.

What unit is SVG?

The <svg> image has its units set in cm . The two <rect> elements have their own units set. One uses pixels (no units explicitly set) and the other uses mm for width and height .

How do I change position in SVG?

When it comes to the positioning of SVG elements like “<rect>” or “<circle>”, there's already a big difference to HTML regarding the syntax. While HTML elements are placed via CSS attributes “left” and “top”, SVG elements can only be placed via “x” and “y” attributes (“cx” and “cy” attributes for circles).

How do I add images to SVG?

To display an image inside SVG circle, use the <circle> element and set the clipping path. The <clipPath> element is used to define a clipping path. Image in SVG is set using the <image> element.

How do I scale an SVG?

How to resize a SVG image

1. Change width and height in XML format. Open the SVG file with your text editor. It should show lines of code as below. <svg width="54px" height="54px" viewBox="0 0 54 54" version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink"> ...
2. 2 . Use “background-size” Another solution is to use CSS.

How do I zoom out in SVG?

Panning and zooming

1. Since SVGs are infinitely scalable, it can be useful to add controls to pan and zoom, particularly to maps. ...
2. Panning and zooming can be easily achieved using the transform attributes translate and scale respectively.
3. However, this will zoom, centred on the top, left corner.

How do I use SVG in react?

Using SVG as a component

SVGs can be imported and used directly as a React component in your React code. The image is not loaded as a separate file, instead, it's rendered along the HTML. A sample use-case would look like this: import React from 'react'; import ReactComponent as ReactLogo from './logo.

Why is my SVG file so big?

The SVG file is bigger because it contains more data (in the form of paths and nodes) in comparison to the data contained in the PNG. SVGs aren't really comparable to PNG images. ... One solution is to rasterize the logo at the required size, and export as PNG (or JPEG even).

How do I crop an SVG file?

How to crop SVG images using Aspose.Imaging Crop

1. Click inside the file drop area to upload SVG images or drag & drop SVG image files.
2. You can upload maximum 10 files for the operation.
3. Set the cropping border of your SVG image.
4. Change the output image format, if necessary.

What is preserveAspectRatio in SVG?

The preserveAspectRatio attribute indicates how an element with a viewBox providing a given aspect ratio must fit into a viewport with a different aspect ratio.

Is SVG responsive?

For an image format that features infinite scalability, SVG can be a surprisingly difficult format to make responsive: vector images do not adjust themselves to the size of the viewport by default.
