Ubuntu :: DJVU Converted (Slowly) To (Massive) PDF

Mar 7, 2010

There are quite a few threads in this forum on how to convert a DJVU file into a PDF (among which this thread the instruction of which I followed.) I converted a DJVU file by printing it to a PS file from the Document Viewer. Then I printed again the PS to file into a PDF from that same application. The second phase took more than 24 hours and resulted in a scanned PDF of less than 500 pages with a size of 315 MB! I have many books of more pages which come down to 1 MB only. What happened in the process to make it so damn slow and so inefficient? Is there a good alternative (not ps2pdf because it provides the same result)?

Ubuntu :: How To Make A Bookmark In A Djvu File

Jul 2, 2010

What happens is that I like the djvu format (a lot!), and I'd like to export all my pdf books (I'm studying the university and I have a lot of pdf books) to djvu format.The problem is that I found very uncomfortable to read a djvu book (with hundreds of pages) without the help of bookmarks or index.I have found some djvu files with bookmarks and that's why I believe that there is a way to do this.I found an application called djvubookmarker on , but this application only works on Windows OS (and doesn't work really good, it has some bugs) so I haven't used wine to use this application with my Ubuntu.

Debian Installation :: All Packages Downloaded Gone - Use Package Downloaded?

Mar 1, 2010

after the netinst finished to download the last package, one hour later the process never continues, I checked the log file and I didn't find anything suspecious, also dmesg and nothing, in fact, in the log file before checked I found that the last line was registered just a minute ago - DHCP renew IP-, so my questions are:

1. all the packages downloaded are gone?, can I restart the installation using all those packages downloaded?

2. where I can find the error or problem that cause that the installation was freezed?

3. in the case that installation needs to start from the beginning, can I use the package downloaded?

General :: Remove Background Layer Of Djvu File?

Jan 11, 2011

I've downloaded some files from the Internet Archive. They come in different file formats and most of the time I use pdf. However, sometimes the scans are saves in colour instead of b/w. This makes it difficult/impossible to read on a dedicated ebook reader. In that case I downloaded the djvu files as on the PC you can select which layer (color, bw,fore,back) one would like to see. Selecting the bw gives excellent results. However, the ebook reader does not has this option.

The question is, how can I remove /extract a layer from the djvu file and save only this layer.

So far I've tried the following two approaches:

1) select bw in the djvu viewer on the PC and printed to postscript file. Followed by a ps2pdf conversion. This works, but generates a fairly large pdf file. Sure, I can again upload it to any2djvu but it just seems to much manual work for each file.

2) I tried the shared annotation feature and said (mode bw). This works on the PC as desired but is ignored on the ebook reader as the other layers are still present.

General :: Windows - Program Which Uses LZW Compression

Oct 4, 2010

how to do Lempel-Ziv-Welch compression using pen and paper for my algorithms and data structures class. Unfortunately we have only a couple of examples in our book of how it is done. I'd like to practice compressing and decompressing text using it, but I need to find a way to check if I'm right doing it right or wrong.

So I'm looking for some preferably free/open source program which can compress and decompress LZW for Windows or GNU/Linux. Programs without binary distributions are fine too.

Fedora :: System Support NTFS Compression?

Oct 22, 2009

I haven't seen this addressed anywhere & quite frankly a "google" wasn't any help. So I pose the question here.
If I, under M$, turn on the NTFS compression, will that drive still work under LINUX?
My thought is that it won't as I haven't seen any control in LINUX for it.

Ubuntu Multimedia :: Mplayer Screenshot Png Compression

Sep 13, 2010

I use mplayer to play my media files. Occasionally I want to take screenshots of media I am playing. I use the -vf screenshot option to take screenshots which generates shotxxxx.png. The issue is that all those png are not compressed and usually large. When dealing with Hi-Def media they are extremely large, each is 4-5 MB in size at the least. Is there a way I can set the option for compression of png images. If I use imagemagick the same files get compressed to like 1.5MB of png file.

Ubuntu :: Compression Excluding Certain Ascii Characters?

Jun 8, 2011

I am working on a project where I am dialing out of a modem!! Old stuff, ya, but the modem allows my device send info from remote sites from my datibase through a phone line so that this IT departments dont have to worry my device being a security issue on their networks.

Any way, the modem I'm using isn't incredibly well designed, and when a certain ascii char is read by the modem, it reads it as an EOF indicator. It is also important that the files I send are compressed.

My question is: Does anyone know of a compression format that allows ME to dissallow IT's use of certain ascii chars?

just as an illustration:

Device --------> Modem ---------> Off-site

and the Modem stops talking to the device when a certain char is passed to it.

Ubuntu :: BZ2 Compression Surely Taking Long Time

Dec 8, 2010

I compressed a directory containing many image files. The directory amounted to 5.3gig. Compressed with TAR using .tgz the compression took a couple minutes at most and compressed down to 4.3 gig. Compressed using .bz2 the compression took about 90 minutes and compressed down to 4.2 gig. Hardly worth the extra time. Do these numbers look normal to you?

Ubuntu Multimedia :: Editing Flac Compression In Banshee?

How do I adjust the flac settings in Banshee to do this? The option to edit the settings is not available for flac? I guess there is a config file somewhere?
