The following is a guest post by Amelia Bellamy-Royds. Here, she shares an epic guide to scaling SVG, covering all the ways you might want to do that. This year, you are going to start using SVG in your web designs. You create a fabulous header logo in Inkscape and you copy and paste the SVG code it spits out into your WordPress header file. Until you open up your web page in test browsers and discover that some leave huge blocks of whitespace above and below the image, while others crop it off too short.
So, scaling SVG should be easy, right? SVG looks great at any scale, but it can scale in so many different ways that getting it to behave just the way you want can be confusing for SVG beginners. The image file describes how the browser should color in a grid that is a certain number of pixels wide and a certain number of pixels tall.
An important side effect is that raster images have a clearly defined aspect ratio : the ratio of width to height. You can force the browser to draw a raster image at a different size than its intrinsic height and width, but if you force it to a different aspect ratio, things will get distorted. For this reason, since the early days of the web there has been support for auto scaling on images: you set the height or the width, and the browser adjusts the other dimension so that the aspect ratio stays constant.
The following example uses inline SVG, adjusting the dimensions of the element dotted linewithout ever altering the size of the drawn graphic:.
Why does it behave this way? SVG is a document. Same with SVG. By default, it will be drawn at the size specified in the code, regardless of the size of the canvas. What happens if you set the height or width or both to auto for these SVGs? The default size for HTML replaced elements will be used: px wide, px tall. Below, I describe the code you need to get the scale you want for the most common situations:.
Other images scale because the browser knows the height, width, and aspect ratio of the image, and it adjusts everything together.
Giving SVG these properties is the first step to getting it to scale. However, scaling SVG goes beyond what is possible with other images. A first glance at the SVG specifications would suggest that the height and width attributes on the top-level svg element will implicitly set an aspect ratio and therefore make SVG scale like other images. So forget height and width. What you want is to set an aspect ratio for the image, and have the drawing scale to fit.
You want a viewBox. The SVG viewBox is a whole lot of magic rolled up in one little attribute. The viewBox does many things:. Its value is a list of four numbers, separated by whitespace or commas: x, y, width, height. Even if your SVG code uses other units, such as inches or centimeters, these will also be scaled to match the overall scale created by the viewBox. The x and y numbers specify the coordinate, in the scaled viewBox coordinate system, to use for the top left corner of the SVG viewport.
SVG is an image format for vector graphics. It literally means Scalable Vector Graphics. Basically, what you work with in Adobe Illustrator.Board of barbering and cosmetology establishment license renewal online
You can use SVG on the web pretty easily, but there is plenty you should know. Notice the artboard is cropped up right against the edges of the design. There is a whole spec for SVG Profiles. I find SVG 1. You can change the size of it though just by selecting the img and changing its width or heightagain like you could a PNG or JPG.
Using it this way has its own set of specific browser support. Essentially: it works everywhere except IE 8 and down and Android 2. SVGeezy can also help. Notice we set the background-size to the size of the logo element. These numbers are aspect-ratio aware of the original size.
The only problem browsers are IE 8 and down and Android 2. Modernizr can help us here, and in a more efficient way than using img. If we replace the background-image with a supported format, only one HTTP request will be made instead of two. Another clever progressive enhancement flavored technique for using SVG as background-image is by using it in conjunction with multiple backgrounds.
SVG and multiple backgrounds have very similar browser support, so if the browser supports multiple backgrounds, it supports SVG, and the declaration will work and override any previous declaration.
Read on! Remember how you can grab the SVG code right from Illustrator while saving if you want? You can also just open the SVG file in a text editor and grab that code.
In other words, it has the same advantages as using a Data URI. It has the same disadvantages too. SVG is already pretty small, but why not do all we can? Upload the old, download the new.
We can jump into the code and give them class names, just like any other HTML element can have. You can use normal stuff like :hover though. Even cooler, SVG has all these fancy filters.

Place it beneath other layers. Maybe white rectangles beneath your objects. When you need to make modifications, you can either export a rectangle individually, or all at once Select them all - the export dialogue box has a Batch export all selected objects option.
But exporting them once beforehand will determine their location and file name. Samuel Dellicour Samuel Dellicour 3 3 silver badges 6 6 bronze badges.

The extra space you are seeing is the space left to accommodate character descenders the tail on 'y', 'g' etc. You can also use vertical-align:top if you need to keep it inline or inline-block.

This is such a gotcha if you happen to be working on a large SVG because you'd never think of it as inline. If you have a little icon, though, it makes sense.

This is similar to what is known from image editing software when blending two layers. The mode is defined by the mode attribute. It allows operations like brightness adjustment, contrast adjustment, color balance or thresholding. Additionally, a component-wise arithmetic operation with the result clamped between [ A convolution combines pixels in the input image with neighboring pixels to produce a resulting image. A wide variety of imaging operations can be achieved through convolutions, including blurring, edge detection, sharpening, embossing and beveling.
The resulting image, which is an RGBA opaque image, depends on the light color, light position and surface geometry of the input bump map.
It's usefulness lies especially in fattening or thinning effects. The input image as a whole is offset by the values specified in the dx and dy attributes. The resulting image is an RGBA image based on the light color. The lighting calculation follows the standard specular component of the Phong lighting model.
The resulting image depends on the light color, light position and surface geometry of the input bump map. The result of the lighting calculation is added.
The filter primitive assumes that the viewer is at infinity in the z direction. It allows the synthesis of artificial textures like clouds or marble. The resulting image will fill the entire filter primitive subregion. It defines a font's outer properties. This process is known as kerning. It can display raster image files or other SVG files.

We were able to accomplish this pretty quickly by using the svg-pan-zoom librarywhich allowed us to easily add UI for pan and zoom controls on top of SVGs. However, after seeing how the control icons appeared over some of our images, it was apparent that we had some overlap issues that we needed to resolve.
We wanted to keep the same control icons, but ensure that they would never overlap the actual image during the initial load. To accomplish this, we planned to add in a small bit of padding to accommodate the space the tools take up.
We use an Embed element to include the SVGs on the page. When using this method, we need to wait for the embedded SVG to load before we can apply the panning and zooming controls. Thankfully, there are a lot of functions available to help make this pretty easy. The code looks like this:. First, we can grab all of the Embed elements using the embeds property of the Document. Then, for each of those elements, we add a new listener for the load event. When the load event is called, we apply the svg-pan-zoom library to the element.
In this case, we were only planning to use the Embed elements for the SVGs, so we can call the svg-pan-zoom function no matter what. Further down, this will be a bit more sophisticated and better support cases where there may be other Embed elements on the page.
At this point, we have zooming and panning functionality, but we still need to add in that extra space for the controls. Again, lucky for us, there are functions that can easily support this! The event listener is certainly a little more sophisticated in this example.
Now, before we apply the svg-pan-zoom tools, we do the following:. Once the SVG has been modified, we still apply the svg-pan-zoom controls as before. However, now we know that the controls will not overlap our image, and we will not be trying to apply them in cases where we don't actually have an SVG. This method of modifying the SVGs provided a pretty convenient way for us to get the control icons to appear as we wanted.
We knew we didn't want to sink a lot of time into changing things. If we had more time, however, we could have considered something like creating custom controls, which svg-pan-zoom does support. Or, we could have even explored other libraries. Given enough time, we could have even written our own panning and zooming tool. There are many different ways to solve issues like this, and thankfully, we found a convenient and effective approach for our needs.
