Remove transparent pixels and blur?

Question

PHP

Hello.
1) How can I remove transparent pixels using Imagick?
Example: a photo with a resolution of 2000x2000, it has a certain vector logo with a resolution of 1000x1000, but in the end, half of the picture remains empty, when resized, of course, it will decrease much less than I need, and the logo will not be visible at all.
2) How can I apply a blur filter to a photo using Imagick? And what kind of filters does Imagick have? I would like to implement partial cutting of pixels so that, for example, every second pixel is transparent.
