DjVu has been utilized in indirect format to minimize Bandwidth considerations on access to Manual pages. The browser plug-in has the capacity to download the entire manual to a single file ( bundled ) or multiple single page files ( indirect ) on your local system. This page is for those who might rather not install or be able to install a plug-in or utilize the Java viewer. You may also wish to experiment with converting DjVu encoded pages into another graphic format, if so read on.
You will need the following dlls (dates just show the ones used here):
cygjpeg-62.dll 08/10/2003
cygtiff4.dll 08/10/2003
cygwin1.dll 05/25/2004
cygz.dll 12/03/2003
along with ddjvu.exe
Any single DjVu page can be decoded to TIFF or PBM, PGM, PPM, PNM or RLE output file with a command line like:
ddjvu -format=XXX p001.djvu p001.tiff
Where XXX is the desired output format from choices above.
Multiple pages can be decoded by creating a batch file which would issue the appropiate command for the desired pages. Such as:
ddjvu -format=tiff p0001.djuv p0002.tiff
ddjvu -format=tiff p0002.djvu p0002.tiff
or
for FILE in `find p*.djvu ` ; do
ddjvu -format=tiff "${FILE}" "${FILE}.tiff"
done
which would decode all djvu files in a directory to tiff files.
Which brings us to:
"Where do I find the DjVu Files to decode on Softlib?"
If you cannot or prefer not to use a browser plug-in, you can access the manual pages via:
We are going to place the DjVu bitsavers manuals in the bitsavers directory due to original scans capturing the data at 400 DPI vs softlib scans at 600 DPI. The difference might impact someone who wished tinker with OCR or conversion to another format.
