about graphics extracted from PDFs, where the OCRed text is behind the
page image. If so I disagree. It is true that the extraction, I use
pdfimages.exe from the XPDF package, yields uncompressed Tiffs. The
reason seems to be simply that the act of reading (and displaying)
includes the decompression already and the extractor makes do without
the extra complication of a compression step (rightly so, one task, one
But in all the PDFs I generate myself I notice that there is no recoding
but all my graphic material is included as is. Whatever I include, Jpeg
in all kinds of quality, PNG in B/W, gray, full colour, 256 colours, 16
colours (great for diagrams and extremely small, but makes PDF
exceedingly slow, so I don't use it), the size of the PDF follows
exactly the sum of the sizes of embedded graphics.
So my guess is you are a victim of a misconception here, but I may have
misunderstood or be wrong.
