view_wview[0] -= number;
view_hview[0] -= number;

view_xview[0] += number;
view_yview[0] += number;

Have fun

I'm pretty sure the easiest way (assuming you're using Game Maker) is to manipulate view_wview and view_hview, but keep the view ports the same.

A smaller view_w(h)view means greater magnification.

As far as I know, there's no easy way to zoom in on a specific object. I don't have too much experience with views my self.

You'll need to do your math with these variables:
the player's x position (player.x)
the player's y position (player.y)
the view's x position (view_xview)
the view's y position (view_yview)
the view's width (view_wview)
the view's height (view_hview)

Alright so I was curious to see if I could do it.
Here is a prototype I made in a few minutes, hope this helps.
