I need to scan some small wiring diagrams, drawings, etc. but the file size is important. Which tends to be smaller, tiff, bmp, etc? TIA Harry Giles

Scan it in as anything you want, at the highest resolution you can get. My scanner defaults to .pnm The files will be big, > 5 meg. The convert them to .jpg at a about 70% quality setting in Gimp. Your jpgs should look good and be about 40k. -- use Perl; #powerful programmable prestidigitation

JPEG is good for photographs but I wouldn't use it for line drawings. See DjVu (http://www.djvuzone.org/). For scanned documents, the DjVu format gives excellent quality and size. I don't understand why so few people use it. SuSE 8.1 contains djvulibre-3.5.8-22.rpm. -- Alexandr.Malusek@imv.liu.se
It looks good, but what I am doing is storing the diagrams, etc. on a web site for download. I use Oracle Small Business on line accounting software, and it allows you to store docs and images for download. This particular use is for wiring diagrams for service being done in the field on equipment. A technician can access the file through any customers PC that has internet access, so reams of diagrams don't have to be carried in the service truck. Unfortunately, the more disk space used for this, the more it costs me. So what I need is the format that preserves readability with the smallest amount of space used that can be opened by W$ and Linux. Harry G On Sat December 28 2002 9:53 am, Alexandr Malusek wrote:

I suggest you try it first and then decide. Install the djvulibre package, it contains the Netscape plugin. (/opt/mozilla/plugins/nsdejavu.so is a symlink to /opt/netscape/plugins/nsdejavu.so). Restart Mozilla, check the plugin is installed and go to http://www.djvuzone.org/djvu/uva/tj_letters/index.html to see an example. Plugins for MSIE can be downloaded from http://www.djvuzone.org/. The Netscape plugin works with Konqueror too - just go to Settings -> Configure Konqueror -> Netscape Plugins and push "Scan for New Plugins" and "OK". -- Alexandr.Malusek@imv.liu.se

The .gif format is the most well-known and suitable format for diagrams, line drawings etc., or in general: illustrations with sharp edges. .png is at least as good for this purpose, but AFAIK is not supported by every browser. SH

Another alternative then would be PDF. It also has very good compression rates and outputs small downloadables while being there for every platform. The full program is about 200$ or so and well worth it for compatibility. I don't think it comes in a Linux version, but then again I have not checked. ----- Doug

A few weeks back saw a discussion where it was suggested that setting printer options to PDF (rather than to lp) allowed files in this format to be produced. Seemed to be ok for me - see attachment.

Looks like the gent has a workable solution then to a mainstream format that provides good compression. It is not the best compression format, but it is widely enough used that each customer site should have access to the ability to read it. I use it for all my docs rather than .doc or txt files now. ----- Doug

Probably because nobody heard of it... Till I read this mail, I didn't know of its existence.
SuSE 8.1 contains djvulibre-3.5.8-22.rpm.
But neither gimp nor xsane support it, and that is _very_ important. How do I create documente, easily? I read the "man djvu" page, which is very interesting, but it is far from clear - there are no examples. Do I have to create a jpeg image, and then convert? How? Will that be in "DjVuDocument" format? Ie, one DjVuBitonal layer, and one DjVuPhoto layer. How about multi page documents? And how about a howto? O:-? You see... it is not easy for newcomers to the format. -- Cheers, Carlos Robinson
