Gradient definition10/27/2022 ![]() Setting these three attributes will allow you to move the gradient around and change its size, as shown in the second rect above. It requires a center point, designated by the cx and cy attributes, and a radius, r. The first of these defines a circle around which the gradient ends. The radial gradient is again defined by two points, which determine where its edges are. However, unlike linear gradients, it's a bit more complex. Like linear gradients, the node can take several attributes to describe its position and orientation. The stops used here are the same as before, but now the object will be red in the center, and in all directions gradually change to blue at the edge. Also, like with fill and stroke, you can specify a stop-opacity attribute to set the opacity at that position (again, in FF3 you can also use rgba values to do this). Duplicate values will use the stop that is assigned furthest down the XML tree. You can insert as many stop colors as you like to create a blend that's as beautiful or hideous as you need, but the offsets should always increase from 0% (or 0 if you want to drop the % sign) to 100% (or 1). For instance, this one tells the gradient to start at the color red, change to transparent-black in the middle, and end at the color blue. ![]() ![]() The two methods have been intermixed for the purposes of this example. This can be assigned directly or through CSS. These nodes tell the gradient what color it should be at certain positions by specifying an offset attribute for the position, and a stop-color attribute. Inside the linear gradient are several nodes. ![]() Above is an example of a linear gradient being applied to a element. ![]()
