Ubuntu Multimedia :: Removing The Watermark From Jpeg?
Feb 18, 2010
I met a guy who is going about with a thermal imaging device. He wants to remove the watermark from the images and tells me that the software developed by the company can do this using only the jpeg. Unfortunately it's only available for windows. I'm dubious that this is possible, but I have to admit I'm not extremely well versed in image manipulation. Is it possible to extract the unadulterated image from a copy with the watermark and other data on it?

I installed Phatch but I can not figure out how to use it. Documentation sucks. I want to watermark a ton of images. Can someone get me started? Or at least agree that with me that Phatch is not easy to figure out?

I know a bunch of commands and I am comfortable using the terminal, I even set a powerpc server but I can't figure out how to remove epiphany on this new computer I'm setting up. I didn't install anything with tasksel. I installed gnome and xorg afterwards... I load it up and 'startx' just fine. then I check around for the programs that were installed. I lik'em gimp, lot's of utilities. gedit. anyway I find epiphany, which I have already established that I dislike, I immediately go to the root terminal (another nice program that comes with gnome) and type apt-get remove epiphany-browser-data the output says it will be deleting gnome... however I have researched and found these are simpy meta packages that don't really matter.... however under the section that states all the packages that will be removed by autoremove there is a huge list... I doubt these packages are safe to remove. how to remove epiphany without removing a huge amount of probably needed software

Somewhere along the line I have managed to get the below error when loading a jpeg in the gimp (either with 'open with' on context menu or directly)Running as an unprivileged user
Code:
Calling error for procedure 'file-jpeg-load':
Procedure 'file-jpeg-load' not found
Opening '/home/fortyfourgalena/Desktop/photos/liza/inkosanalodge_20061201/20061201_171151_PC010620.jpg' failed: Procedure 'file-jpeg-load' not found
[code]...
This happens on a system running 10.04 / 64-bit. As I seem to recall a recent gimp update (might be wrong), I checked a 32-bit 10.04 laptop and it does not show the behavior. For information: the 64-bit system has some additional stuff installed for image processing (ufraw and darktable) but I have been using this already for a while without issues. The other main change on this 64-bit system before I noticed the problem was the installation of a geforce 8400 video card including the 'nomodeset' option in grub and install of the latest driver from the nvidia website. verify that the gimp on a 64-bit system is still functioning.Further a 'repair' from within synaptic throws the following error
Code:
E: /var/cache/apt/archives/gimp_2.6.8-2ubuntu1.2_amd64.deb: subprocess dpkg-deb --fsys-tarfile returned error exit status 2
Note: I found some messages regarding this problem on the web but they were referring to older kernels (2.6.8); and people reverted back to an even older kernel. And yes, there have been a recent kernel upgrade.

I am using the following command to create a video of a bunch of jpeg files. The problem is that some of the jpegs are portrait and others are landscape. Ffmpeg is stretching the portrait images. Is it possible to maintain aspect ratio of the jpegs... perhaps put black bars on the portrait images using ffmpeg?
ffmpeg -r .75 -f image2 -i Image%d.jpg output.mp4

I use GIMP to edit pictures. When I cut part of one picture and put onto another picture, I try to save it as a jpeg, but it says "You must export image before you can save- JPEG Plug-In can't handle transparency." Is there another plug in that allows me to do this?
Also on a GIMP related subject, how can I set the eraser tool to transparency instead of white/other colors?

Any recommendations, the only thing I can find is inkscape, gimp doesn't seem to offer that facility.

I'm trying to find out how to add watermark to a video using a ffmpeg via console, because I have to do it quick. There is tutorial on ..... (other forums use also this video tutorial) for this but there is a small problem - in ffmpeg 6.1 there is no more vhook subsystem which is used in tutorial...

I've used ubuntu before, mostly because it works when windows doesn't and I just got a new amd fusion netbook. The acer aspire one 522.
I have a couple issues, 2 with grub, and one with an amd watermark.
1. There are two ubuntus and two ubuntu memory tests in the grub, I can't see any difference between them, after I booted the first time into ubuntu and updated, I restarted and the grub gave me two ubuntus.
Can I remove the second one from the list? (not an issue I just want to clean it up)
2. I need to make windows 7 the default operating system, I've looked at other guides and I can't figure it out. I've tried menu.lst, and when I try grub.cfg I can't change the default.
3. I installed the unofficial drivers for the wireless adapter and graphics card (6250 on fusion) and now everything is working fine with them, except I have the unremovable watermark in the bottom right corner that says "AMD Unsupported hardware"
How do I remove this?
BONUS question! How do I tell ubuntu, this is my netbook, stop denying me access to my own computer and let me in that folder!
I can't access the root folder, and I'd like to do install things without ubuntu asking me for my password every time. I'm not worried about other people being on this netbook, no super valuable info, and not really anyone else is on it anyway. Any way I could give it a master password and roam freely inside my netbook?

I have the following issue: I want to upload some documents on my site(mostly pdfs) with watermark and as far my status is: I have managed to get my watermark in:
transparent png
pdf format
>> When it is a text/pdf I use a script using pdftk, which merges the pdf version of watermark to the pdf document (success)
>> When it is a scanned document(pdf) if I use pdftk, it only works if I apply the watermark as stamp (foreground not background). But in this case the watermark overlaps the original document despite the fact that watermark has the right opacity.... (fail) So the only solution is to apply a transparent watermark. So the question is:How to make a pdf transparent Or how to apply watermark from png file I tried adobe acrobat with wine and it applies the pdf watermark as stamp(foreground) with right opacity so I suppose it was a kind of bug maybe from pdftk, but I would like a command like way to do it so that I can make a script.

I know the basics and have read the Ubuntu Pocket Guide several times and reference it a lot still. I went to the trouble of installing Fuppes onto my system (Ubuntu Server 9.1) and after configuring it and playing around with it I did not get the results I wanted. I soon after found PS3 Media Server which did almost everything I wanted to instantly with no configuration.
But what to do with the fuppes install? I did the following
Code:
sudo apt-get autoremove fuppes
Just for arguement sakes I attempted to run
[Code]....

what i did was, remove evolution mail from synaptic, what i wanted to do was just remove the indicator applet from the task bar. i read a bunch of bad stuff about removing evolution from synaptic vs just removing the applet.
im worried. did i break anything or put my security at risk. after, i used a command (older) (sudo apt-get install ubuntu-desktop)to install ubuntu desktop. because i thought that it would fix evolution. then i went to synaptic and installed a package called evolution. i rechecked evolution in applications menu. however, i notice that i have both a checkable evolution and two evolution icons. nothing 'seems' broken. im not sure if it ever was. and evolution calender pops up as normal, as does the the installed plain evolution. they both seems to be an exact copy of the other.
all i really wanted to do was remove the indicator applet. did i make a serious mistake. since ive had ubuntu, ive reformatted a lot because i was worried i made a mistake of some kind. however now im into the more "make a mistake and fix it stage' as im pretty happy with my current desktop and have worked hard to customize it. the command, sudo apt-get remove indicator-messages removed the mail icon. i still am worried that i broke something, or put my security at risk. also, now i have two mail icons. evolution mail and calendar, and another just called evolution.

I use EasyTAG to edit the tags of my music. I believed I could also use EasyTAG to remove embedded album art, but this is not entirely the case.EasyTAG appears able to remove references to an embedded image so that the image will not appear in audio players and tag editors. However, the image must still exist within the audio file because the file size remains exactly the same. Contrast this with Mp3tag where removing album art also decreases the audio file's size.My question: is this a bug on EasyTAG's part? If so, what Linux program could I use instead?

I'm trying to batch encode some old mpeg2 vids to x264. After much playing around, I've finally found some settings that work across the board in preserving quality. The good news is the converted vids are about half the size.
I'm using handbrake to do this and with over a thousand clips, converting via the gui would be way too time consuming. Naturally CLI is much faster for something like this. I've found all the flags and arguments to pass to handbrake
So, suppose my vids are in ~/MyVideos. I want to store my converted vids in ~/ConvertedVids. The problem is that there is a whole folder hierarchy after ~/MyVideos that goes several levels deep; I want to preserve this. In handbrake, the output file is a parameter like so:
Code:
handbrake_cli -i input_file -o output_file
I know stripping away the filepath upto ~/MyVideos/ should be trivial with awk. I don't know awk and was wondering if someone here could give me the command I need.

How do we get rid of the "Unsupported Hardware" watermark? The best advice I've found is to download the video driver directly form AMD. So I got this file
ati-driver-installer-10-12-x86.x86_64.run
I've no idea how to install it, and after I double-click it seems Ubuntu doesn't know what to do with it either. Any ideas?

My OS is Ubuntu 9.10 64bit. I have been having problems with audio in several of my applications - all of which were fixed by removing Pulseaudio and installing Esound. After uninstalling pulseaudio, there is now no volume bar in the notification applet on my desktop panel.
In addition to this, my volume keys on my keyboard (Lenovo Y550 Ideapad) no longer work. Is there an application I can install that will put a volume bar back on my notification panel (using Esound)?

It was recommended to me that I remove pulseaudio and re-install alsa. All the howtos on reinstalling alsa had instructions for re-installing alsa from the source. Is it possible to re-install alsa from the repos? If so what are the necessary packages that I need to install, for a complete re-install of alsa?

These should be my last pleas for help with regard to Fedora 13. I've been unable to turn off the notifications that appear in the top right corner, despite a decent amount of searching on google. I can't remove any notifications package without removing a bunch of important software along with it. Also, F13 refuses to "Safely Remove" either of my external disks. I have to yank out the usb cord, touching wood each time.

I would like to remove it, because typically I don't need to see it all day. Its enough if it shows up when i go to the upper left corner and see all running applications.
I found this: [URL].... but if you add the repo in that article and update apt,the repo fails.
second try(this one works): [URL].... different extension, same goal. but this one works with gnome 3.14.2 allow gnome to change files when firefox asks.

I want to remove GDM altogether, naturally I tried:
sudo apt-get --purge remove gdm3
But it appears to be taking some lower level gnome libraries down with it. As soon as it's removed, I can no longer start gedit or gnome terminal for example. If either is run from the terminal, I see, "Cannot display" or something along those lines. I end up reinstalling gdm3 and everything works perfectly.I already used update-rc to stop the gdm daemon from booting altogether, I just want to remove it now for a greater sense of cleanliness I guess.

It all started Tuesday morning. I woke up and turned my computer on. Normally I just leave it on all the time, but I turned it off the previous night for some reason. When I turned it on, everything worked fine for about 10 minutes, until my monitor said "Monitor Working Out of Scan Range." I messed with the settings on the monitor to try and get it back, but to no avail. Restarting would make it work, but for even shorter periods. It eventually would display the manufacturer image (Everex), and then go dead again with the same message.
I thought it was the monitor at first, and got a new one. The new one is a wide screen 18.5 inch Dell IN1910N. The problem persisted, so I knew it wasn't this. I kinda figured it out when I started smelling something burning coming from my computer, and discovered it was the graphics card I installed awhile back. It is the pci ATI X1550, and its fan no longer worked.
So I figured, well, I will just remove it and go back to the onboard video. Doing this worked fine, until I got to the stage where it tried to boot to the Xserver, and then the computer just hangs. No sounds indicate I ever get to a logon screen or anything.
Now, I tried commands like sudo dpkg-configure xserver-xorg, and it asked me a lot of questions about my keyboard, but didn't fix my video. I also tried the "Xfix" option in recovery mode, and it purged all the old fglrx drivers, but that didn't help either.
I am currently using a live CD (I was doing straight command-line for awhile, after I also played hell getting the wireless working). I tried literally coping and pasting the entire contents of the X11 folder over, but that didn't work either (the xorg.conf files were the same anyway). I don't know what to do to get my old partition to boot X correctly.
All the commands I was copying before are not in my terminal now, and I'm not sure exactly what command-line information you need. I know that Openchrome is supposed to run the onboard VIA video, but I don't recall the command that tells me everything about it.

i have 2 boxes w/ squeeze/gnome. my home one has bigger HDDs (to me anyway), so i can install/trick out for days. my work box however, has a single paltry 12Gb HDD (and no, i can't afford to run out and buy a bigger one).my question is this: can i slim down my gnome install my removing what are to me at work, non-essential apps (evolution, totem, etc)? if you try to remove any of these in synaptic, it says it will ALSO remove gnome altogether.

When I open Yast's software management in opensuse 11.4, there's like 400mb of changes it basically forces me to install. For instance, flash player, libre office stuff, gstreamer etc.
I remove these from the download list, but when I go install something like the nvidia driver I need, it still downloads and installs all that other stuff first, whether I remove it from the list or not. It still makes me agree to the flash player terms or it won't install anything.
How can I get all these recommended updates off of there and just install what I want to individually?

I've installed Debian GNU/Linux, from a Testing NetInstall ISO, then after setting up the system, I've installed the KDE desktop.Well, I like to have a system with the applications I want, not the applications that the system wants for me, I mean, that's the point of GNU/Linux, isn't?
Thus I want to remove some applications from KDE, let's say KWrite. I know it's a good text editor, but Kate is way better, at least for me, and... I should have the authority to decide what applications I want on my system, I think you got the point.So I installed Kate, and when I try to remove KWrite, APT asks me to remove nothing but this applications: kde-baseapps kde-plasma-desktop.
I don't understand why do KDE forces me to get rid of the entire desktop... when I'm just trying to remove a single application, and a replacement it's already installed.
