I answer to Boccaccio.The question on my discussion page was:How can I obtain a small pdf from a djvu file?
For all about Monteverdi file here : http://imslp.org/wiki/L%27orfeo%2C_favo ... 2C_Claudio
I did this:
Install djvu viewer and firefox djvu plugin.
This viewer has an option:export as.....and here you can choose (pdf tiff png etc) but you must flag the options "force bitonal G4 compression".
I told that file was buggy because when I choose export as a pdf I obteined a white file. So I decided to convert djvu to tiff (G4 compression),I opened the tiff multipage file with Okular and I printed it to pdf.
This way usually works very well with all files ....but i told you that file was buggy .....because here and there I found some little white stains instead of notes......
so I switched to
I installed djvu viewer and I printed that file by a virtual pdf printer flagging the option "print colors like black".This is the file you find on imslp.
Usually all works perfectly on unix sistems too.I tried on a Mozart quartet file found on that site and all worked well.
To bypass that problem about Montevedi Orfeo.djvu on unix sistems you should do this (but it's a long way):
Open djvu file by okular (okular is a djvu reader too) , select a page at once (by selection tool) and save as png. After that convert all your files to pdf.(but you need alot of time)
