Dear all,

I've created this.
http://www.cirma.unito.it/research/alternando/photoBook.pdf

(it's 5 mB)

The cover and the separators in the pages are generated stretching on  
layers the same image (a pdf generated by Metapost)

% cover
\setlayer	[mybg]	
		[x=0\paperwidth, y=0\paperheight]
		{\color[lightgray]\externalfigure[alternando]
		[height=1\paperheight,width=1\paperwidth]}
% red horizontal separator
\setlayer	[mybg2]	
		[x=0\paperwidth, y=.45\paperheight]
		{\color[darkred]\externalfigure[alternando]
		[height=.1\paperheight,width=\paperwidth]}
% gray vertical separator
\setlayer	[mybg3]	
		[x=.9\paperwidth, y=0\paperheight]
		{\color[lightgray]\externalfigure[alternando]
		[height=\paperheight,width=.05\paperwidth]}


In Preview.app on macosx it's all displayed as expected
(this is a png snapshot of the horizontal separator:
http://www.cirma.unito.it/research/alternando/hbar.png
  ).
  But Acrobat displays the separators (the cover is ok) as a sequence  
of filled boxes. Can it depends on some resolutions setting? Or what?

I did this interview where I just mentioned that I read Foucault. Who  
doesn't in university, right? I was in this strip club giving this  
guy a lap dance and all he wanted to do was to discuss Foucault with  
me. Well, I can stand naked and do my little dance, or I can discuss  
Foucault, but not at the same time; too much information.

hi andrea,

zoom to a level of 6400% and you can give the answer yourself. this is
just the way acrobat's rip is interpreting your separator gfx.

you can try to remove the horizontal border lines (also too fine for
printing). additionaly you can use (slightly) alternating background
colors per line to emphasize the horizontal borders (like in exxel).

btw: very nice location (only sunlight is missing); please drop a note
when the final pdf is released :)

best wishes, peter

many thanks Peter (sorry for the delay).
I solved converting the resulting figure in Preview in two pngs and  
including them as png.

Best
