Scaling objects is handled by applying
to your desired object. In this case, “x,y” refers to the horizontal scale and vertical scale of the applied object (not x and y positioning as with the translate property). To scale an object uniformly, you need include only the x value, as the y value will be assumed to be the same.
In each case, the value of 1 is equivalent to “100%.” So, to apply a scale transformation that is twice as large as the original object, you would apply transform="scale(2)". Reductions are thus handled using decimal values; to apply a scale transformation making an object half as big as the original object, you would apply transform="scale(0.5)".
To illustrate this ...
