I did an infeasible amount of work comparing different approaches to  
getting an optimum image.  I concluded that making texi2pdf force the  
images to 6 wide, and using the larger image produced by lily was the best  
approach.  The real issue about this (if we wanted the pdf to look much  
better) is that using bitmapped images in PDF documents is not ideal - it  
would be much better to use lilypond book and to use .eps images.  However,  
-book doesn't appear to have a -dpreview option.  This would make a good  
enhancement.

I'm fine with any of these changes, but I feel out of my depth so we should  
definitely have a countdown for patches for any of those options.

The image sizes on big-html are almost certainly fine, if the images were  
there at all - see Issue 1663.  For the pdf, the images we create are too  
big to fit across one page of the PDF.  The images are created by this:


$(outdir)/%-small.png: $(outdir)/%.png
pngtopnm $ | pnmscale -w=600 | pnmtopng  $@

in Documentation/web/ly-examples/GNUmakefile.

The w=600 means they're 600 pixels wide, which is ~6 and is just too  
wide.  To correct this would mean 2 changes: add a line to create a smaller  
image for the PDF; and check why thy appear so bad in the PDF anyway - they  
appear badly scaled up. I'm looking at this.

Comment #3 on issue 982 by philehol...@googlemail.com: web big-html and pdf  
look bad

http://code.google.com/p/lilypond/issues/detail?id=982

It turns out that pnmscale (or pnmtopng) sets the image's resolution to  
72dpi.  texi2pdf obeys this, so a 600 pixel image is rendered in the PDF at  
8.3, which a) looks crap and b) is too big.  The 2 options appear to be to  
1) set the image size at 6 explicitly; 2) to use the larger image anyway,  
at possible cost to the size of the doc or 3) use imagemagick rather than  
pnmscale to resize the images.

we've lived for a year with this.  It can't be all that important.

http://code.google.com/p/lilypond/issues/detail?id=982

Lots of problems with image sizes in the big-html and pdf versions of web
manual.

Also problems with with @docLinkXYZ macros; they should have a special
  @ifset bigpage
  @ifset tex
portion to handle the different relative URLs of the different output forms.
