Graphics, Figures & Tables ⇒ Fade a Piece of Text

[jsmith6]

I'm trying to make a piece of text fade out to white and another piece of text fade in from white.

This is how it should look like:

I can do this with HTML and CSS in two simple steps:

1. Create a box with a vertical gradient from alpha to white (for fade out).
2. Place this box over the piece of text I want to fade.

The HTML+CSS code for this is attached. Point is I don't know if this approach is appropriate for LaTeX. I've found an example which I'm trying to modify:

Run LaTeX here

I can see that \pgfdeclareverticalshading will not accept transparency. I also have no idea if I can place this box over a piece of text but make it so it covers the bottom 3cm of text.

I know I can start using shades of gray over different parts of the text but that means I have to depend on the wrapping and it kind of loses it's point.

Can anyone provide a lead on this?
