Hi folks,
Having repaired my GIGI power supply and found my local copy of the user and
techical manuals (big TIFs, I'm assuming there are tools available to let me
convert these to PDFs?)
I seem to remember doing it with Imagemagick's convert utility before -
from a shell or DOS prompt it's probably as simple as:
convert '*.tif' output.pdf
(with scaling / rotation etc. hints as necessary)
I'm not sure if it'll "explode" multi-image TIFFs and append in
sequence
to the output file or not without any help.
Note that it's *not* quick by any means and eats memory; Imagemagick
buffers everything as 32bit internally (the one thing I hate about it!)
so even if you have mono images as input it's still going to treat the
images as 32bit before appending to the output pdf file. For that reason some of the alternatives might be
better for mono images
(ISTR 'tumble' does the same job, although I've never tried it)
Yes, tumble does a great job converting a series of monochrome TIFFs
into a single PDF. Any stuff I'm archiving is first scanned at 600 dpi
and saved as G4 compressed TIFF. The I create both PDF and DJVU files
from the TIFF images. Finally, the TIFF images
(archived as a tar
archive for convenience - I prefer to keep the original scan
data, just
in case) and the PDF + DJVU files are dropped into the archive FS.
Funnily enough the first thing I do when I download a bunch of scans in
PDF format is convert them to multiple TIFF images, as they're easier to
handle in whatever app is appropriate for what I'm trying to do versus
some sucky PDF viewer ;-)
Just for reading a scanned article I find the PDF version easier to
handle. But still keep the original TIFF files just in case.
Regards,
Alex.
