General :: Windows - Convert PDF To Grayscale ?
Aug 3, 2011
I scanned a document in color to PDF, and I don't want to re-scan it.
How can I convert this PDF document to grayscale (preferably without loss of other information)?
My usual toolset of doPDF, pdfsam and the Neevia online converter don't work here. I was thinking I could simply print to PDF and select the Grayscale color option, but doPDF doesn't have that option.
I'm using Windows, but I can probably handle a solution for any OS.

I had a Windows XP Home box setup with MySQL, Apache, bind9, phpBB. Then one evening while preparing a Linux replacement my Windows XP Home tower died. It completely croaked. It won't boot up past POST at all. No beep codes or anything! It just sits there with the power on like a brick. I cannot boot it to grab the database through the webserver with any web based MySQL script system. I also do not have another Windows box that I can install MySQL on.
There is no possible way I have to retrieve any MySQL databases that I had on it except by mounting the hard drive where MySQL stored the databases for Windows on it. I've Googled for hours on end trying to find a solution but to no avail. I tried simply copying the contents of the database as-is from where it was on Windows to where it would be on Linux but when I try to browse the phpBB forums I get this error:

I have some checksums.md5 verification files from an ntfs external drive, but using windows notation: instead of /, spaces between file names (not escaped), reserved shell characters (like (, &, ', to name a few). The checksums.md5 has a bunch of checksums and filenames:
[code]...
I want to use this checksums.md5 to verify the files that I've copied to my machine: but I'm on a Linux, so I need to convert the names inside checksums.md5 from Windows to Linux to use the md5sum utility from the shell. The first line in my example would become: f12f75c1f2d1a658dc32ca6ef9ef3ffc My Windows & Files (2010)/[bak]/testing.wmv Is there some application for this (converting a file listing, from windows cmd notation, to linux shell notation) or will I need to create a bash script using sed that just "replaces" what is "wrong" with the filenames

I want to convert many text files(copied from windows workstation) into utf-8 encoding file. Yes, iconv is available for it. However, I have to give source file encoding at the command line parameters! The problem is, at most case, I am not sure the source encoding of it. And, I also want to use a script to convert many files recursively.

I'm running Xfce 4.6.1 and xfdesktop 4.6.1.1 (or so aptitude said). When I use 'None' image option - just colour - I get the colour I ask for but if I change that to either 'Single image' or 'Image list' then both the image and the background colour are made greyscale.
I have tried looking through all the options I could find to do with Xfce and searching Google but I don't know how to phrase it as my searches tend to bring up black and white wallpapers.
Running X as a different user on the same computer does not cause the same problem which makes me think it might be cause by a user setting though I spent a long time with a black and white wallpaper and do not know when the issue first arose.

I'm trying to print a PDF from Evince it don't work at all...
When I try to print in grayscale it send a blank paper to the printer...When I try to print anything in color I can't change the margin of the paper, it always put like ZERO margin and the text go throw the end of the paper.
The paper size is A5 (Half A4) and the printer is in LAN in a Windows computer.
It's me or when I print in grayscale it print faster? So, it's an update or something? Because last time I printed from Ubuntu (like a month ago) it printed perfectly OK in grayscale (I don't know about the margin).

I have backup outlook.pst files on the non-bootable windows os partition. I can access these backups from the Ubuntu partition, but of course they aren't readable. I understand that one can use Mozilla's Thuderbird on Windows os to establish outlook exportable files for the Ubuntu client,but I don't have that option as my Windows os is not booting. I've found Ubuntu so dependable that I have no interest in attempting another expensive and lengthy recovery process of windows.

I have Ubuntu 9.04 and just installed Sound Converter. I am trying to convert a bunch of .ogg files to mp3 to play on my iPod and it's not working so well. In the Sound Converter options I have is set to convert to high quality mp3. I choose the folder that the files are in and after a moment (slow laptop) Sound Converter populates, I hit 'convert' and it shows that the conversion completes in two seconds. All that it did was create the new folder structure of artist/album but there is nothing in there. Not sure what I am missing. I used Sound Converter before and it worked fine.

Now, when you right click on audio file, under 'scripts', you will see ConvertAudioFile option.

I have a lot of .flac files downloaded from several sites. Most of them come with a .cue file, and the .jpg with the cover, etc. It seems it is the intention of the uploader that one rebuilds the original CDDA. However, if I had a stand-alone CD/DVD player with flac I would hardly see the point of converting the flac to cdda. Furthermore, I could even play the flacs with a software player although, in this case, the audio quality would not be so good due to the noise picked up by the signal from the PC digital circuits.

What I am trying to do is to convert a mass of files from standard Windows text encoding to UNIX encoding(462 .txt files). After a bit of searching, I found this bit of code, changed the necessary parts, put in "Sleep" so I could see the output and ran it:
Code: #!/bin/bash

Using dspspy, I've recorded a number of audio files ending in .rec. Only problem is, it seems the only possible way to play them is through `cat file.rec >> /dev/dsp`. Neither sox, lame or audacity can convert them to another format.Any command-line tools that can? A .wav or .raw would be best. I just can't seem to find any conversion tools.

I have a unique issue. Unique in the sense that I have only found the opposite of what I'm after so far. Here goes:
I have a special bootable "Linux" USB. Tested the USB and it boots up and builds any old PC - with an appropriate BIOS. I would like to convert this USB - better still its contents - to an ISO.
Reason? VMWare server doesn't support USB bootable BIOS at present. Not sure it ever will.

I have some wma file which I would like to convert to mp3. My situation is that the wma files are in different sub directories. I already have a good script which I found online but its problem is that you only can convert wma in current directory. I would like to edit this script, so I can be able to convert my wma files in sub directories too.
A copy of script is below:

I don't have that much experience in scripting but I think that don't need that much modifications to meet my requirements.
