How to achieve a total transparency on gradients


Recommended Posts

Welcome to the Serif Affinity forums, @intro55.

I won't pretend to be an expert on gradients, but it looks to me like you defined your gradient to be transparent on one end, and it is. You've oriented the gradient vertically, and it looks transparent to me at the upper dot on the gradient line. I'm not sure why you've marked the spot you did with red arrows. That part of the gradient is still supposed to be blue, and it is.

It looks to me like the gradient on the object/layer matches quite closely what you have in the gradient window, accounting for the rotation.

It looks like you do not have a transparent background, which makes it look like your white half of your gradient is not transparent. Here's a screenshot with a transparent background, the white half is set to 0 %

There is no a way to achieve a full black to transparency gradient?

You must set the same color as the other side of the gradient.
In your case, if the initial color is black, you must set the black on the other side gradient, even though its opacity will be zero and the color will be completely transparent.

It works, tyvm. I was trying with white all the time.
