How can I clip a filter like “blur” to a shape? There are tutorials that show how to make a shape disappear behind another shape. But I’m looking for something different:
I have a background image and above (z-axis) I have a smaller transparent rectangle. Now I want to apply a filter like “blur” but only inside the rectangle.
Actually my final goal is to apply the filter to the outside of the rectangle, but I’m already stuck with applying it to the inside:
Is this possible?
