Hi John, you are right, png files are better than jpg, but Greenstone
doesn´t process it !!! I made a PDF document composed with png files. I
imported it in Greenstone but it doesn´t export each page, so when I
browse the document in the collection I see no images ! If I use jpg
files, Greenstone process it with no problems !

Is something about the PDFPlug? I also use -complex option but nothing
happens.

Thanks in advance.

Diego

You could try using .PNG format images instead of lossy JPG or tiff.
