I have an object that I've applied a linear gradient to:
that I would like to fade to transparent at the edges:
But I do not know how to do this, given that inkscape doesn't let you apply two gradients to one object (I would like to apply a radial alpha gradient over the linear color gradient). I've accomplished the look here by just using a white elliptical gradient on a new shape, which surrounds the colored shape, plus a white background. But that's obviously not what I want; I want the shape to have a fully transparent background.
Is there a way to achieve this with some kind of Clip & Mask? Or something else?
