Ubuntu :: Gimp Batch Process Multiple Files Index To B&W?
Apr 15, 2010
I scanned hundreds of pages in gray scale and would like to batch process them to B&W. You can do this using the gimp GUI. what it does is get rid of all the gray shading from reflections off the paper when scanned. So you get crisp white backgrounds with black text and diagrams. I would like to simply do this to the entire group directory at one time as it would be quite a lot of effort to open them and do them one by one.
I have some random files in a folder. I want to rename all of the files in a batch process. I have a text file that contains the Currentname of all the files in the folder, as well as a text file with all of the Newname of files in the folder. I want to replace Currentnames with Newnames.
For example, here are the names of the files in the folder: 1.mp4 2.mp4 3.mp4
I have a text file with the Currentname of all the files in the folder: 1.mp4 2.mp4 3.mp4
I have a text file with the proper Newname of the file: a.mp4 b.mp4 c.mp4
I want to rename Currentname with Newname in the folder. So when I go to the folder the Newname of the files are: a.mp4 b.mp4 c.mp4
I don't know if it's possible but GIMP is able to receive command line arguments, so why not? Basically, I want to create a batch (action, macro or what it may be called) and then set up a cron job which will run every hour. So, it would be something like "If an image is in X folder, then resize, watermark & move it to Y folder".
I'm completely new to scripting and I'm trying to figure out how to write a script that will get a list of all the files in a directorywn through any subdirectories.When I have the list I want to o each file in VI and change the fileformat. So far all I have been able to figure out is that VI can do the batch processing and that "ls -R" gets me the recursive file list. I'm still pretty clueless on how to do the batch process with the VI editor. I think I'm supposed to use the Ex mode but I don't know how to get the list of arguments from the filelist into the editor so they can be processed. If it matters the files were all written in a Windows editor and have gotten the MS carriage returns so I want to do a :set ff=unix command on all the files without having to go into each file manually, there are over 300 files that need updated.
I need to close images I work with when I'm done with them. As an example scenario, I can open several images and work on them, but every time I open them they create new instances in gimp, meaning the gimp could in the end be using several gigs of ram for images I can't even see are there.Also, I can't start gimp for batch only (Using 2.7 dev version)Code:$ gimp -i -b "(script-fu-thing 1)"This is a development version of GIMP. Debug messages may appear here.(gimp:11407): Gimp-Core-CRITICAL **: gimp_viewable_get_stock_id: assertion `GIMP_IS_VIEWABLE (viewable)' failedgimp: fatal error: Segmentation fault
I want a simple short gimp batch script that will take one image, paste it into a predetermined layer on another image, export as png and discard changes. Unfortunately, I can't find any tutorials on using gimp batch. Anyone know any such tutorials (Or better yet, what my script needs to be)
So far this is what I have. I need a way to loop through the layers to check the name of them, I also need a way to ditch the previously opened files from memory (Otherwise gimp still has both images in memory) (I'm going to mark this solved so I can make a cleaner post once I get it together)
FC 12 64 bit. When I print an image from Gimp 2.6.8, where is most of the work being done to create data that the printer can use - on my computer or on my printer? The printing of images on my HP Laserjet 4000 or my Officejet 7000 is relatively slow. Can I speed it up by having more of the computation done on my computer instead of on the printers? Or is most of the work already being done by the computer?
I have a process running on Linux.When i do ps -eaf | grep <myProcess>, it show muliple entries for <myProcess> with different pids for each entry.Kindly tell me what could be the reason for a process having multiple pids?
I have a large image that I want to print over 4 pages, each page showing 1/4 of the overall image, that I will past together. I'm doing this from GIMP on an up-to-date fc12 system. Searching around I find that there is a "scale" field in the print dialog and the lp command that cups supports and according to the documentation if I set scale to "200%" it should do what I want.However, when I set scale to 200% I get only one page with the upper left 1/4 of the page and then nothing. How do I get it to print the remaining 3 pages?
I recently installed JDK 6 runtime using apt-get install in terminal. I downloaded a .jar file and attempted to run it but I got an error telling me it has blocked the file for some reason.Another thing was, how can I run batch files? I know ubuntu doesn't come with something like MS DOS but is there anything similar that I can run batch files with?
Is it possible?I am mainly looking for A shell script or program that can convert a Batch (.BAT) file into a Windows executable (.EXE), or A program that can be run from MS-DOS that can turn a batch into an exe.
So I have a php script that is setup to stream flash video (.flv) and I absolutely love having it. The problem is that any files I want to stream have to be in .flv format for it to work properly as .avi and others obviously don't stream well. Up until now, I've used FFMpeg to change the format from .avi to .flv, however the process takes a lot of time if you have a lot of videos, added to that you have to do one file at a time definitely makes it a pain.Does anyone know of a bash script that can take all the files (i.e. avi, .wmv, .mkv, .mpeg4) in one folder and automatically convert it to .flv? Then possibly delete the old files? Low resolution is fine, so long as it at least viewable. Does anyone have a script or know of a program that can do this (I run Ubuntu 10.04). I think FFMpeg has the best chance of doing this, but I don't know the syntax to actually do so.
I've searched the internet, and while I have found a few scripts, they didn't work for me (still looking into two scripts I found.I am currently messing with them to see if I can get them to work).It would be immensely helpful if someone knew of a way to do this.I also forget to mention that I have used Winff, but I was looking more for a bash script to do this so that I can set a cron job to convert them every hour or so.
I have recently been tasked to extract the subtitles from a lot of mkv files. Hundreds of them, maybe even more than a thousand. To do this, I modified a script I found online:
#!/bin/bash IFS="|" if test -z $1; then
[Code].....
So in the above example the subtitle is actually in track number one and my script would be borked for that particular file. Is there a way to integrate mkvinfo into the script and parse it to see what track should be extracted? Like, read it line-by-line and change the value of some #TRACKNO variable everytime a string like "| + Track number:" appears, and stop when a string like "| + Track type: subtitles" appears? Maybe even skip doing anything if there aren't any subtitles.
PS: I actually prefer SRT subtitles to ***. If there was some command line tool I could use to convert the resulting *** file to SRT I would be much obliged.
a movie is encoded with AC3 in 6 channel audio, what I get out is all of the sounds except for voices, which in 5.1 would be sent to the center channel. What I usually do is fire up avidemux and convert the audio to mp3 stereo, as converting to a 5.1 format usually ends up with a very odd sound (like running everything through an echo chamber). What I'd like to do is run a script to batch-convert these files from AC3 to MP3. The video format may vary, but they are usually XVID. I am comfortable at the command line, but I am not well-versed in audio/video tool terms. I don't need anything extravagant, I just want something that works. Heck, even if it is done one at a time, having a shell script that I can use to simply type:
I have quite a few sound sample files totaling over 4 gigs in size with around 80 root folders and then around 34 sub folders. i have a total of 13 DVD's in the above format. how do i "change the date" on all files in one go is that possible?
I'm trying to clean up a few hundred thousand mp3 files and I'm dying to find a way to automate some of the mechanical tasks I keep doing. It seems like at least two of these tasks could be easily accomplished with something at the command line, but I don't have the chops/know-how to figure out how (and would really rather not trial and error with batch deleting files & folders...).
1) Delete all folders named "_MACOSX" (and all subfolders/files contained therein) -- Basically, I'd like to apply this command to a few hundred directories that may or may not contain a subfolder called "_MACOSX" that I'd really like to get rid of.
2) Delete all files named "*.m3u". -- Similar to the first, I want to automatically scan all directories and subdirectories in a given location for all instances of this file-type and delete them wherever they're found.
3) Move all files named *.txt", "*.doc", "*.pdf" to a specific location. -- Similar to the last, except instead of deleting, I'd like to just move them, so that if there is anything worth keeping, I can keep it.
Well a bit earlier today I was trying to install the latest VLC following steps from this link:it instructed:Code:sudo add-apt-repository ppa:gnome-media-player-development/developmentsudo apt-get updateBut after the sudo apt-get updateI started getting errors at the end.. here is my log after running it:
Code: sendblink23@sendblink23-Ubuntu:~$ sudo apt-get update Hit http://us.archive.ubuntu.com lucid Release.gpg
W:Failed to fetch http://ppa.launchpad.net/alexftimie/...source/Sources 404 Not Found , W:Failed to fetch http://ppa.launchpad.net/alexftimie/...-i386/Packages 404 Not Found , E:Some index files failed to download. They have been ignored, or old ones used instead.
I just did something stupid... I wanted to remove a numeric prefix from a bunch of files in a folder (EXT4 filesystem), and I ran the following Python commands to rename the files:
I run a script which generated about 10k files in a directory. I just discovered that there is a bug in the script which causes some filenames to have a carriage return (presumably a '' character).
I want to run a sed command to remove the carriage return from the filenames.
Anyone knows which params to pass to sed to clean up the filenames in the manner described?
I am running on Linux (Ubuntu)
The character causing the filename to 'break up' accross multiple lines appear to be a CR (carriage return) instead of ' '. The filename is being diaplayed in thetitle of a text editor with %0D in the positions of where the file name breaks up. So I need to remove the CR chars from my filenames.
I have a lot of pdf files and I want to convert them to a lower quality for the web. I tried to use the following command (using ghostscript): Code: gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/default -dNOPAUSE -dQUIET -dBATCH -sOutputFile=output.pdf input.pdf Is there a way to make a batch to do this for all pdf-s in a folder?
If you had Gimp 2.6 (with gimp-plugin-registry installed) and installed Gimp 2.7 to try its new goodies, but Layer Effects are not showing, and when executing "gimp" from console you get these *nasty* errors:
Code: This is a development version of GIMP. Debug messages may appear here. gimp-user-install: migrating from /home/user/.gimp-2.6 Traceback (most recent call last): File "/usr/lib/gimp/2.0/plug-ins/layerfx.py", line 23, in <module> import gimp, gimpplugin, math ImportError: No module named gimp .....
If you haven't install the 2.7 version yet. Before upgrading, backup "python" directory and then just restore it after installing 2.7.
like to update it on occasion. Recently I attempted to edit an image locally. I use vbulletin, which relies on png for it's forum icons. When I tried to change the default image for a new one I created using GIMP, I saved it as a *.png file. Yet, when I looked at the saved file - it was actually a *.xcf file (which I've never even heard of before).What gives?ensure it is saved with a png extension when I select png extension, instead of the xcf extension it seems intent on saving as?The image was originally a jpg, if that makes any difference. I can't see as it does though. When I was on Windoze, I used Paint Shop Pro - and if I told it to save a file with a png extension, it amazingly saved it with a png extension
Some of you may have had with issues after installing GIMP on Lucid Lynx 10.04. Which may be directly related to "gimp-help-en", which could prevent you from installing other applications and preforming system tasks. If so, use this method to fix it.
Process: (Terminal > $ sudo apt-get install gimp)
1. After installing Gimp go to the terminal:
2. Then load up the language support application:
3. Then it will ask you to install the "gimp-help-en", confirm it.
4. Fix'd
I think this issue is directly linked to a systems with multiple languages, but I haven't been able to test this theory out yet.
possible to rename a list of files in batch in order to maintain the last part of them, then purge a central section and then again maintain the extension?I.E.:
Amarok will play flac files just fine, but when i try to index them into the library via "Update collection" they are not added.
All other threads i can find on this kind of thing also have Amarok not playing flac....but if i drag and drop them in, they play just fine, so i know its not a codec problem.
Is there something i have to enable? Like in some media players, you can set which formats are scanned for...but i cant seem to find such a feature available in any of the Amarok settings...
