If you want to use a repeating pattern of some kind, the easiest way to do so is to create an SVG document that defines it and use it as a pattern fill. SVG images are typically smaller than bitmap images and remain sharp on high-dpi screens. We are going to be using svg patterns in three ways. First an svg pattern needs to be defined.
For example this pattern generates small circles, each of radius 1px and positions them at coordinates 1,1 like so:. To define a pattern that can then be used in svg, one must add it to the defs section of an svg container. Note that the SVG pattern we defined above gets translated into a string.
For example:. Patternfills offers several premade patterns that can be used already. Now you can. For example, all of these patterns were created with this library:. If you'd like to use Pattern Fills in your application.

SVG seems to support only linear and radial gradients, but I'm thinking there might be some way to use a transform to simulate what I want. Examples on that link do not work. In my answer to this similar question, I used six linear gradients to approximate a conical gradient.
CSS now supports conical gradients, although browser support is mixed at the time of writing this. If you dig into this pageyou'll find code that approximates a conic gradient in SVG by drawing it as a series of 1 degree arcs.

I think you're describing a radial gradient with many colors. Can you show an image of what you're trying to create? Active Oldest Votes. There's no standard support to do angular conical gradients.There are three ways to fill or stroke SVG elements. You can use a solid color, a pattern, or a gradient.
SVG provides for both linear and radial gradients. You define your graphic in one place and reference it in another. The x and y values determine the starting and ending points of the gradient. In other words this will be a horizontal linear gradient.
While I chose to use percents, both x and y values can be either a percent or a number between 0. I assume the result is what you expected or close to it.
The gradient can be added to a stroke as well as a fill. I set the fill of the rectangle to a solid color and added the gradient to the stroke.
A stroke-width of 20 should be more than enough to see the gradient. You can define as many as you want. Here I added a third color stop so the gradient passes through red in between the blue and green.
The default value is 1. The first gradient is from the previous example. The second gradient references it and changes the direction to vertical by setting new values for x2 and y2. You can see in the resulting graphic that the gradient is the same blue to green transition, but now it runs vertically instead of horizontally.
The next two attributes are new, but again they should look familiar. Markers had markerUnits and patterns had patternUnits to allow the marker or pattern to scale or not to scale. Guess what attribute gradients have and guess what it does. The gradientUnits attribute takes two familiar values, userSpaceOnUse and objectBoundingBox, which determine whether the gradient scales with the element that references it or not.
It determines the scale of x1, y1, x2, y2. The gradientTransform attribute allows you to add transforms like rotate and transition to any gradient. Here I added a gradientTransform to the second gradient from the previous example and rotated it —50 degrees.
The rotation is harder to see with gradients than with patternsbut hopefully you can tell the gradient here as been rotated. If not, compare it to the previous result and you should see the difference.
The spreadMethod attributes takes one of three values pad, reflect, or repeat. All three are easier to understand with an example.
Note : Unfortunately there are browser issues with the reflect and repeat values of spreadMethod. Neither works in Safari, though they should work in other browsers. The gradient transitions back and forth between blue and green. The reflection leads to a gradient transition back and forth between the two color stops. It almost looks like it comes into focus at the point where a solid color is displayed and falls out of focus somewhere in the transition.
It starts the same way by transitioning from blue to green, but at the exact point where it previously reversed itself and transitioned back to blue, it now abruptly changes to blue and transitions back to green. Like patterns, markers, and symbols, gradients are defined in one location and then referenced and used as the fill or stroke on another SVG element.
Using the xlink:href attribute you can have one gradient inherit from another, making it easy, for example, to define color stops on one gradient and change the direction of the transition on another. If you understand how to work with linear gradients, radial gradients should be pretty easy to understand and work with as well.
Download a free sample from my book, Design Fundamentals.Jakob Jenkov Last update: SVG gradients are a way of filling shapes with color, in an uneven fashion. That way the fill or stroke of a shape can change from one color to another. This can look really nice for some types of graphics. The first rectangle has the same stroke color all the way through, but a gradient fill color light to darker green.
The second rectangle has a gradient applied to both its stroke and fill color. The third rectangle has a gradient applied to the stroke, but has no fill. The fourth rectangle has a gradient applied to the fill, but has no stroke. Linear gradients changes evenly from one color to another in a linear fashion.
You already saw some simple examples of linear gradients in the beginning of this text. The color can change either vertically, horizontally, or along a vector you define. You can also just fill part of a shape with a gradient instead of the whole shape.
Here are a few visual examples before we continue onto the explanation:. The first rectangle uses a vertical gradient.
The second rectangle uses a horizontal gradient. The third rectangle uses a diagonal gradient gets darker towards lower right corner. The fourth rectangle only fills the right half of the rectangle with gradient. All this is possible using SVG's linear gradients.
Here is an example:. Reading all of these attribute descriptions can be very confusing. Therefore I have created an image that illustrates the meaning of these attributes:.
Radial gradients are gradients in which the colors change circularly rather than linearly. Here is an example image:. As you can see the colors now change in a circular fashion. The three last green rectangles only vary in the center of the radiation of the lightest green color. The first green rectangle has the colors spread out from the center of the rectangle.
The second rectangle uses the top mid of the rectangle. The third rectangle uses the top left corner as center. This SVG code actually defines the 4th rectangle shown in the example above. The center of a radial gradient is the center of the circular color spread.
If you picture your radial gradient as being a circle, cx and cy marks the center of this circle. The focal point of a radial gradient is the "angle" of the color radiation.
If you think of the radial gradient as a lamp, the focal point decides what angle the light from the lamp hits the shape with. The gradient then looks a bit like a light source hitting your shape. You will most likely have to play around with the center and focal point of your gradients before you get them right.
I know I did that, just to create these simple samples.We've all followed Angular tutorials, and the end result is usually a neatly-formatted "List component" screen showing a list of data, perhaps with a "Details component" to see further details about a chosen object.
But wouldn't it be cool if we could get Angular to create beautiful, responsive diagrams instead?Wow.. You can Export Adobe After Effects Animations as SVG! Here's how.
That's what we're going to create here. Obviously, this looks great, but won't be suitable for all scenarios or types of data, but hopefully this article will teach you some useful techniques, and show you what is possible with Angular and SVG, without too much coding. You can see a "live" version of this website by clicking here. You can also click on an employee to bring up their details.
You'll also notice that I'm cheating a little bit: each of the Employee records already has an x and y coordinate. We're not going to write code to take a set of hierarchical data, and work out where to place it on a new diagram.
Everyone's data will look different, and this wouldn't add much value to the article. This article is more to give you creative ideas which you can use in your own projects, rather than being a step-by-step introduction to Angular.
And there seem to be very few examples showing how to use Angular and SVG together. I hope you find this interesting article useful, please remember to leave a comment if you do!
Gradients in SVG
To create the Angular app, I will now run:. Okay, let's go to that folder, and start Visual Studio Code:. Now, by default, all Angular apps will run on port I like to change this, with each new project, just to make sure there's no clashes. To do this, let's open up package. If we were to now go back to our Command Prompt, we would be able to run our new Angular project:.
Okay, let's quickly check that it worked okay. If you were to now run the app, you'd see a fairly dull screen, showing four columns. When you resize the browser window to a smaller width, the columns will stack one on top of another. Yeah, it's dumb Okay, assuming this is all working fine, let's add some resources to the app. Our little app will contain some employees data, and photos for each of them.
I've also included some icons that I've used in the "full version" of this app, which you can find online. At the top of this tutorial, you'll find an assets. You should then see these 3 folders and their files, in Visual Studio code:. This contains the list of employee records, and all a list of relationship records - which employees are the managers or sub-managers of other employees? The structure looks like this:. In the relationship table, we have an employeeId and managerId value, each of which are foreign keys, linking back to employee records.
It also contains a type string, which is either " Manager " or " Sub-manager ", which we'll use later, just to show how we can easily change the appearance of our diagram's lines to reflect different types of relationships. Yes, I know, those two interfaces should be in separate files What we're doing here is defining two new interfaces which describe how our json data looks like, and importing the json data into two variables, employees and relationships.
By default, Angular can't import data directly from a json file. To fix this, simply open the tsconfig. If you were to now open localhost again, you'll see that it displays our list of employees, along with their photos, and date of birth values. Notice that I've displayed these records using the Bootstrap Cards styling.
I don't know the official term -- it's the kind of gradient you see in color-pickers, where it varies by angle. SVG seems to support only linear and radial gradients, but I'm thinking there might be some way to use a transform to simulate what I want.

SVG Gradients - Linear

Active Oldest Votes. There's no standard support to do angular conical gradients. Good find. And one neat thing about SVG is that it is the source code. Like HTML, if you can see it, there's no way for the source code to not be included. Hi Ken, I dont know how could it help unless I have the source. I couldn't just hardcode the svg path in my page to generate gradient. I am looking for an angular gradient across a fill circled arc. Not so easy to read I might add.
This looks and awesome! But any suggestions how do I generalize it for an arc with given outer and inner radius? Thanks a lot! You can get discontinuities of colour where two linear gradients meet. Probably the safest place to align the linearGradients with would be the corner of the inner radii. Because then that triangular area between where the two gradients end would be all the same colour.
Does that answer your question? Hi, I needed a gradient along a full arc just like you, but I needed it to vary between 2 colors only - blue to violet Show me an example arc you want to colour - in a fiddle, for example.Learn Development at Frontend Masters. When I create filters, shadows, transformations or gradient backgrounds in CSS, it feels amazing. Who would have thought CSS would come this far.
No need to use images for any of that stuff. Despite all this evolution, CSS still has limitations. For instance, background gradients can only be created in linear or radial styles, but not a conical shape. However, we still have to wait for the W3C to formalize the feature and for the browsers to implement it, which might still take quite some time. In the meantime, I will show you how to simulate a conical gradient using CSS3 only. One of the most interesting features of CSS preprocessors is the mixin.
A mixin is a blend of function and include which, when called, returns its contents. This mixin is only used to set properties of shape and placement, creating a circle of absolute position and centered horizontally and vertically in relation to its parent. By combining a mixin circle with the clip property, we can get a semi-circle. Can you imagine what is going to happen if we rotate one of the semi-circles? The clip: rect top, right, bottom, left property restricts the visible area to a rectangular element, which causes only half of the red circle to be seen in the example above.
The same principle is applied to the blue circle, the. At this point we would have a full circle which is half red and half blue. See example. Since we want to create a full circle by combining semi-circles, from the seventh item first item in the second halfwe must reverse the clip:. From the seventh item, the. We are almost done!! We need to change the colors and the angle of each element. The rotate property has some important points. Its angle is defined according to the number of colors in the circle.
But from the seventh item on, the other half of the circle starts, remember? Thus, the process we just described stops at the seventh item. We will then start the very same process again, but this time, the rotation will take place on another direction. If you are a good observer and understood everything so faryou should have noticed that our our umbrella is actually a fan! So for the last color of the first half of the circle does not get on top of other colors, we need to reverse the index of these elements.
The blur filter is responsible for mixing the colors. But, by applying the blur, the colors strain the limits of the circle. This is the end result :. The conical gradient can be used in different ways to create different effects. But one of the most interesting applications is the Color Pickeras in the example below:.
