Debian Multimedia :: Rotating Images On Linux
Oct 21, 2015
I have been using Debian 8 with XFCE for the past 9 months.
Recently I had a simple job of going through a bunch of receipts (several hundred) and rotating them so that they were all portrait. Easy you may say? Linux fails dramatically.
My only requirements are a visual tool where I can see the image and then a button or even better a keyboard shortcut so I can rotate clockwise/anti-clockwise and move onto the next.
Here are my attempts at this:
ATTEMPT 01 - GIMP
GIMP works but you have to load it up everytime, and the save as feature tries to push XCF format onto you. I just want to overwrite it.
ATTEMPT 02 - GTHUMB
GThumb works as well, but its horribly slow, pops up an annoying image distortion prompt everytime you do it, and it moves the image you've just rotated to the end of the filmstrip and takes you there with it. Unworkable in reality.
ATTEMPT 03 - Nautilus
Nautilus simply fails altogether with a GTK error in the background.
ATTEMPT 04 - Ristretto
This is the default viewer with Debian 8 and it works. Or so I thought. When you rotate in Ristretto it just rotates it within the software and doesn't persist it within the image. So I went off and did 50 of them, thought I had and when I went to view them in other software they were still landscape. Incredibly frustrating.
ATTEMPT 05 - Windows 7 - Standard Image Viewer
This just works. I click one button, rotate left/right and then click next and it's saved. Ristretto could do this if it actually persisted the changes but it doesn't. So I find myself doing this job in a Windows 7 Virtual Machine because Linux just simply doesn't provide a working tool for me.
Any software that does the above simple task well in Linux?

I'm looking for an app for Linux that creates bootable images. Back when I used windows, I used Imgburn. Now, I need an app like that for Linux. Wherever I looked online, I saw either one (or both) of these ideas.
1. Run Imgburn under wine
2. Get k3b
I don't like using wine because the programs run very slow. I'm not sure exactly how to get k3b to produce a bootable image. So that's where I'm stuck.

Does linux support images in .jpeg format? What is the difference if I save my image in .jpeg or .JPEG or .jpg from a linux point of view? Is this case sensitive?

I have a problem with my Debian 8 installation. This morning I was playing around with libvirt and virt-manager while I was routinely installing updates using apt-get. While doing that, my system crashed (probably because of the running Win8 VM). After resetting (in hardware), I got access to the emergency console where I tried executing "dpkg --configure -a" which worked.
After restarting, I first noticed that the login screen background (just the normal Jessie one on LXDM) was missing and the screen was black instead. After logging in, I saw that nearly every image/icon/whatever is missing. For example:
- the icons in lxpanel (I use LXDE)
- the copy and paste icons nearly everywhere
- the New Tab icon in Firefox
- many more icons
- the desktop and login background
A few images are still there:
- interestingly, the lxpanel icons are replaced by "icon missing" icons which still work
- most icons in Firefox except for New Tab
- all images of LibreOffices (so this problem might be Gtk+ only)
Some programs don't work (obviously because they can't load their menu icons and don't a fallback). An example for this would be Inkscape. It crashes at start:
Code: Select all(inkscape:2513): Gtk-WARNING **: Error loading theme icon 'document-open' for stock: Format der Bilddatei unbekannt
(inkscape:2513): Gtk-WARNING **: Error loading theme icon 'document-open' for stock: Format der Bilddatei unbekannt
(inkscape:2513): Gtk-WARNING **: Error loading theme icon 'document-open' for stock: Format der Bilddatei unbekannt
[Code] .....
Note: I use a German system. "Format der Bilddatei unbekannt" means something like "Format of image file is unknown", "Bildtyp 'xpm' wird nicht unterstützt" means "xpm image type is not supported".
Concerning the desktop background, I looked at /etc/alternatives/desktop-background and found a correct SVG image which was the one I had before.
How I could restore these images?

I recently reinstalled Debian Lenny. Now, many images are greyed out. For instance, I can't see graphs in Google Analytics; can't change time period.Also, some video sites require the latest version of Flash. When I go to Adobe download, I only see *.debs for Ubuntu. But I'm not sure which version of Ubuntu is compatible with Lenny.

It seems to me that there is a media player that can play .iso files. which one or ones do this so that I don't have to install the dozen or so that are in the repositories.

I have finally made the switch from Windows to Linux even in my workstations at home, after several years running it in servers, routers etc and i only miss one single program that can make me delete my last virtual machine with Windows 7 forever, a professional radio broadcasting program. I have been broadcasting radio for several years and have mostly used Sam Broadcaster for Windows, have been testing a lot of linux-variants but nothing can compare with Sam or Radiodj.ro on the Windows-side. I found the package "Mixxx" lately and it's almost suit my needs but still not quite there yet with soundFx, station ID's jingles, request functions etc.
I have managed to get Sam Broadcaster (version 4.9.1) working very well with Wine, the only problem is that the audio sounds really bad. The sound crancle a lot and i have been trying several workarounds and spent hours on google without success. If i could get the audio sounds better i think the best solution for now is to stick with sam since i know that program in my sleep and it can be configured to use MySQL database to store everything from playlists to lyrics of songs etc, it will be some job to switch program if it doesn't use MySQL.

I use Debian Jessie with Linux 4.4.6 from backports and obviously systemd. My graphics card is Intel HD 5500, my processor is Broadwell i5-5200U. I use Toshiba Satellite Pro laptop.Suspending to RAM works fine, but I have problem with hibernation. Resuming from hibernation also works, but only when time between hibernating and resuming is a few hours. When this time is for example 10 hours (I hibernate before going to sleep and resume next day morning), I can't resume from hibernation. I see only black screen and keyboard doesn't work. In that case when I type in terminal
Code: Select alljournalctl
I can see:
Code: Select allPM: Starting manual resume from disk
PM: Checking hibernation image partition UUID=8640b415-7de4-48c2-b6ab-2629a5894316
PM: Hibernation image partition 8:4 present
PM: Looking for hibernation image.
PM: Image not found (code -22)
PM: Hibernation image not present or could not be loaded.
This is weird, because when I hibernate and resume after 2 hours, everything is OK. My SWAP is large enough (I have 16 GiB of memory and 16 GiB of SWAP).
I have Code: Select allGRUB_CMDLINE_LINUX_DEFAULT="quiet resume=UUID=8640b415-7de4-48c2-b6ab-2629a5894316 acpi_osi=linux i915.enable_rc6=1 i915.lvds_downclock=1 i915.enable_fbc=1 pcie_aspm=force" in /etc/default/grub and Code: Select allRESUME=UUID=8640b415-7de4-48c2-b6ab-2629a5894316 in /etc/initramfs-tools/conf.d/resume
I hibernate my computer using hibernate button in Kickoff in KDE Plasma.

I am running Linux from a DVD, not installed. I am not good with installing software, but since the DVD cannot be corrupted, I am content to operate this way. Lately, I have been having problems that previously did not occur. When I try to click on the checkbox to get rid of emails, it doesn't register in most cases, or when it does, I am clicking multiple times so it registers twice, meaning it is unchecked again. Even more frustrating is some issues that are affecting my ability to update my business. I am trying to modify spreadsheets (text not calculations).
Whenever I try to click & drag to select something to change, it keeps jumping around to select only some of what I want, something else or some combination of the 2. When I try to copy and paste several fields from 1 column to another, everything from the several fields in the source column ends up together in the last field in the target column. I am also trying to download some images from a website. There is a single column of links to the images. I have to click on the link to get to the image in order to copy it, then back out to continue looking for more links to do the same.
My computer keeps jumping back 2 steps, then forward 2 steps, and sometimes I lose my place in that list. I could deal with it if it were a small number of links, but this is a list of probably close to 20,000 links. Again, i am operating off of a live DVD so this should not be corruptible, but this has just started happening, and has been an issue the last several sessions.

I am configuring an ubuntu system for a friend of mine, he is Arab and he used to watch (with windows) the films on this site: [url]
I tried to open the site with firefox but I cannot see the image on that page, I see the cursor changing shape and clicking with right button in the properties I see they are gif images, furthermore clicking on the (not displayed) images should open a link to the film but instead a blank page opens with error.

I'm running Ubuntu 10.10 with an NVIDIA GeForce 6100 video adapter and my monitor seems to flicker whenever the the computer is processing. My system is up to date and I did install the recommended NVIDIA driver. The monitor isn't going blank or anything like that, it just seems like every once in a while different images will pop up for less than a second. Any ideas as to what the problem might be? I've attached a copy of the xorg.conf file as well:
Section "Screen"
Identifier "Default Screen"
DefaultDepth 24
EndSection
Section "Module"
Load "glx"
EndSection

I know that ImageMagick's convert program can be used as follows to convert a collection of images -- say, in PNG format -- to a PDF file:
convert *png output.pdf
The problem with this is that each image is then stretched to fit on one page, whereas I would like to keep the original dimensions of the images and put as many as possible on one page in the PDF file before moving on to another page.

Is there a Linux app for mounting and playing audio CDs from image files? I have saved disc images of nearly all of my CD collection, but I have yet to find any convenient way to play them.
Because of the nature of CD audio, every CD image has an accompanying .cue file, so there are actually 2 files (*.iso or *.bin and *.cue) from each disc. VLC Media Player will play DVD .iso images directly, but doesn't know what to do with audio CD images (or the .cue files).
Mounting and unmounting the images at the command line is tedious, given the very long file paths. I'd rather have a GUI-based app. Does any such thing exist for Linux?
FWIW, Acetone ISO doesn't work. It doesn't want to mount my *.iso format CD images. Probably some funkiness of the CD audio format. I think it is what the Acetone devs call a "multi-sector image." Likewise for the *.bin images of CDs.

I am just spent half an hour hunting for a thing that should be totally available already:USB install images of Ubuntu, knoppix and all the others.And, the only good way are so far complicated tutorials where you extract the stuff from an CD image. Why??Hasn't everybody notices that CDs/DVDs are vanishing big time? That more and more systems don't have the readers anymore? Instead of following a 10 point instruction list, it would be nice to just be able to download a Ubuntu 8.10 or whatever USB image and be able to beam that DIRECTLY to a USB stick with a dd command.
Or am a missing something here? Does this exist?It should by no means be mariginal, considering how important USB stick in specific and flash memory in general have become.

In GIMP, can I rotate an image by only a few degrees? It's a scanned image of a crooked xerox copy, and I want to straighten it. I see options only for rotating by 90 or 180 degrees.

I just burned a copy of a DVD.
Great. Now, will I be filling up my hard drive every time I do this? Where does Brasero keep the images that it makes of DVD's and CD's when it copies?
I would like to delete them, after I copy an image...

I'm trying to setup MythTV, but whenever I do so, I get no text on the X window setup screen. The language selection takes a very long time (input is super delayed) and I don't see anything on the screen. This last time I ran it it went the farthest it has gone before, but it always hangs at the theme file selection, as shown by this Terminal output.
Code:
Loading window theme from /usr/local/share/mythtv/themes/Terra/menu-ui.xml
Loading menu theme from /usr/local/share/mythtv/themes/defaultmenu//mainmenu.xml

I have a bunch of images I took of the same thing, but I was holding the camera, so each one moves a little bit. Is there some way to crop the images so that the focal point doesn't move between pictures?I've done some searching but I haven't had much luck finding anything.

I've been using GIMP's 'save for the web' tool to reduce the file sizes of images.
I now have a directory with about 50 images. I'd like to avoid processing them all by hand.
I have a (very) basic knowledge of programming, and I'm comfortable with the commandline. I don't mind doing some homework on how to use new tools.
All I'm really concerned with here is reducing the file sizes of the images I have.
What possible pathways are there for me to prepare large amounts of images for the web?

I have a Sony Bravia TV (ex700) that has DNLA support (spotty at that from what i've read). What i'm wanting, is the ability for a DNLA type device to stream my ISO images (dvd images).So far I've tried Mythbuntu and have had some issues with it. Biggest issue is that the DNLA server does not show up on my sony. Other issues are around iso images playing faster than normal (through the host, not DNLA).
I've also tried minidlna but there appears to be no support for ISO files.At this time, all i want is a linux based DNLA server that supports ISO files.

i have no problem. But with user2, when i start to read a video file, i have no image, just a black screen.The sound is ok, the time is running normally, but no image. *It tested with vlc and gnome-media-player, it is the same. *I have no error message, when I start the program in a console. *I suspected a permission problem, and i checked all the groups, but i don't see any difference between user1 and user2.

I have a very big image directory: One image per minute, whole a year, captured from a webcam. Now I want to make a video (15 or 24FPS) with all the webcam captures, to see how it changed during this period. I've tried automotion, but it makes a very low quality video, besides it blocks with lots of images. I've also tried dvd-slideshow, but it's not possible to make a more-than-1FPS video.
I also need to change the date in each webcam's images, because they are wrong, so it needed to overlay a little layout with the right date for each image, is that possible to manage within some application? Preferibly shell applications which supports lots of Gb of information (anyway I always could make little videos and then glue them)
