Blurring only a part of an underlying picture to make the text readable

[Martin Diestelmann]

I would like to reproduce and use a function that I saw in one of the first presentations of Publisher. It was about text on the picture with the climber. I saw that it was possible to draw a rectangle (Designer) behind the (multi-column) text and the photo area under this rectangle could be blurred with the box blur (Photo) so that the text in front of it was easily readable. I am not able to reproduce this effect: I always have to create a duplicate of the photo, place this duplicate photo in the rectangle. But this is not the solution, because every time I change the layout I have to duplicate and frame the picture again. What am I doing wrong.

Check your PDF, but the text will be rasteried... perhaps not what you want in the end.

Thank you very much for your help!

One can, after applying the effect, group the effect with the image/pixellayer>rasterize this group, to have it not rasterise the text though

The text won't rasterize if the blurring is nested as a child of the image (as opposed to inline with the image and text).
So, the rig can remain flexible and non-destructive... there's no need to rasterize (or make a copy & rasterize) the group/effect before export. 🙂

HI @Martin Diestelmann. Why make this so complicated? Why not put a Box Blur on the underlying graphic layer and mask it?

Isn't that what we're doin'? 😉 
Just using a vector instead of a pixel selection to mask.
