React svg gradient

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.Deprecated since SVG 2 This feature is no longer recommended.

A recommended approach for defining a platform-independent custom cursor is to create a PNG image and define a cursor element that references the PNG image and identifies the exact position within the image which is the pointer position i. 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.

The gradient covers an area defined by x1, x2, y1 and y2 transformed by the gradientTransform. That area does not cover the shape's bounding box.

It didn't when I tried it but OK. Active Oldest Votes. Why should offset be a percentage? This solved my issue with SVG linearGradients. I was using react-inlinesvg and this issue was not resolved by it.

The gradient can be of two types:. In this example, we will see the Linear Gradient. This is very useful if you want to make a custom button with a curve effect or any multi-color background.

In this example, we will make three buttons Note: It is not only for the buttons you can use gradient in any view with three types of gradient background:. Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App. Assuming that you have node installed, you can use npm to install the react-native-cli command line utility.

Open the terminal and go to the workspace and run. If you want to start a new project with a specific React Native version, you can use the --version argument:. After the updation of React Native 0.

You can combine any or all of them as the masking content. You can also create some interesting masks using gradient or pattern fills. Hopefully it will give you some ideas for how you might use masks in your work. Notice that these values are all between 0 and 1, because the default maskUnits is objectBoundingBox.

The linear path also gets a fill of The blue outline not shown in the code shows the mask boundary. Like clipping paths, you can use multiple SVG elements as the content inside the mask. In this next example I used four rectangles and placed them so each covers a different quadrant of the circle. Notice I gave each rectangle a different fill so each quadrant of the circle is a slightly different shade.

By now you can probably tell the fill is the most interesting part of the mask. The boundaries of the mask act like a clipping path, but the fill determines how much of the graphic below shows through. In this example I use a gradient as the fill. Notice that I defined the linear gradient first and used the id of the gradient as the fill for the mask content.

The mask itself then gets an id which is referenced by the circle. Once again note the pattern. The SVG graphic the circle references the mask gradient-mask and the mask content references the gradient gradient for its fill. Also notice that the mask content is another unexciting rectangle, but because the fill is more interesting, the mask, even a rectangular one, is more interesting.

You can also create a pattern and use the pattern as the fill for the mask content. The difference between this example and the previous one is that I changed the gradient to a pattern of repeating circles.

The pattern fill color changes the value of the original green circle. And of course you can combine patterns and gradients, which I did here by borrowing the linear gradient from the example in the previous section and using it as the fill on the pattern. Hopefully you agree that masks become more interesting when the mask is more than a simple shape with single solid color fill. You can get create with the shape of your mask by building them with paths or combining multiple elements as the mask content.

More interesting, I think, is when you get creative with the fill and use gradients, patterns or both as the mask fill. I offered two clipping path example posts.

Guess what I have planned for the masking? Next week I want to show you a few more examples that make use of text and images as the mask content and allow you to create even more effects.

Download a free sample from my book, Design Fundamentals. Hi, I use the same type of gradient masks you do in my product. Any idea of why this is not working in Firefox 57? Is it possible to use a path with only its stroke-width as a mask? Thank you.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.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Simply change the dependency. For instance the podspec file does not contain the right data author attributes etc. Using the styles from above, set start and end like this to make the gradient go from left to right, instead of from top to bottom:.

The trick here is to render the text twice; once for the mask, and once to let the gradient have the correct size hence the opacity: 0 :. In addition to regular View props, you can also provide additional props to customize your gradient look:.

An array of at least two color values that represent gradient colors. Example: ['red', 'blue'] sets gradient from red to blue. Coordinates declare the position that the gradient starts at, as a fraction of the overall size of the gradient, starting from the top left corner.

An optional array of numbers defining the location of each gradient color stop, mapping to the color with the same index in colors prop.
