Software :: Compose Two Smaller Images Into One Larger Image
Mar 13, 2009
I've been using python's PIL (import Image in py2.5) and the command line utility ImageMagick to add text to images and compose images. I can't figure out how to get the composed image not to crop. That is, suppose I compose A onto B to create C. A is short and wide, while B is tall and narrow. I'd like C to be tall and wide, but instead it has the same dimensions as B.
The width of A is determined by dynamic text. My current solution is to get the width and height of A and B, and then create a maximally sized image, T, onto which I compose B and then A.I'm just wondering if there is some way to streamline this. Can ImageMagick do this for me? These operations take a non-trivial amount of time.
I have four thousand images. I want to create one thousand images where each of those is tiled with 4 images. This is possible with montage out of the imagemagik package. But it is way too slow.Does anyone know of a high performing program which can compose four images to one image?
I have an Ubuntu server and i've installed drbl-clonezilla to clone and restore pc, I have a 40 gigabyte image to be deployed on other pc's with larger hard drive ex. 160 GB or 240giga, my problem is that when I deploy the image on a larger disk I end up with a disk with a partition of 40 GB and the rest unallocated, how can i restore the the disk and use full disk space, the goal is to automate the process. In clonezilla-drbl there is the possibility to start a "prerun" and "postrun" fonction that could help complete the deployment process.
I need to clone a 160GB hard drive with Linux Mint 9 (not more than 10GB used) to a 30GB SSD that is partitioned carefully (aligned to cylinder boundaries) and is currently running Ubuntu (which I wish to overwrite with Linux Mint 9). The SSD has a /boot partition, / and swap. The source (160 GB) does not have a separate boot partition. Can anyone help me fill in the steps below? /dev/sdc will be the source (160GB) and /dev/sda is the target (with partitions 1,2 and swap on 5).
make a copy of /etc/fstab from the target drive before proceeding. Ready the target partitions. Can I reuse the existing destination partitions on the SSD? Ready the filesystems on each of the target partitions. /boot is ext2, / is ext4 and swap is already set up too. As I said, all contain data (Ubuntu) that I wish to overwrite. So what steps are needed here? Do I need to erase anything (files, etc.) before the copy/clone? next, use dd to copy MBR (right?) And exclude partition table:
Code:
dd if=/dev/sdc1 of=/dev/sda1 count=1 bs=446
Mount the source and destination drives:
Code:
mount -t ext4 /dev/sdc1 /mnt/source mount -t ext2 /dev/sda1 /mnt/boot_target mount -t ext4 /dev/sda2 /mnt/root_target
I suppose I can leave the swap partition on the target untouched. Copy the files from the source partition to the destination
Code:
cp -a /mnt/source/boot /mnt/boot_target cp -a /mnt/source/ /mnt/root_target
then I assume I go to /mnt/root_target and delete the /boot directory, right? Change /etc/fstab to reflect the new partitions. I mount by label. Will my partition labels be intact after this? Do I have to make any changes to GRUB? Anything else?
I am trying to upload some pics on my Facebook account using Firefox. When I click on Facebook's file upload icon, Firefox bring up a 'File Upload' window. I noticed that smaller image file is previewed on the lower right hand corner, while bigger image file is not. Is there anyway I can change this behavior or maybe change what Firefox is using to browse my files?
I've been working on getting another OS installed on my computer for one of my classes (OS specific assembly instructions). To get this OS running, I had to start using a GPT rather than a MBR table. I backed up my Ubuntu partition (ext4) using the old-fashioned dd command. I've since been able to get everything working again after a dd restore.
The problem is that my original Ubuntu partition was only about 50GB and the dd image only takes up 40 GB. After I restored the image to the new drive (146BG), gparted is reporting 119GB used and only 26GB free. What can I do to reduce the size of my install to 40GB again?
When looking at the disk in baobab, it says the the filesystem is only 47.2 GB and that only 20.9 GB has been used. This is likely what the old partition's breakdown was. So my new question is: How can I make the filesystem capacity (47.2 GB) equal that of the partition that it is on (146 GB)?
I am running Fedora 10 and would like to move from my 40gb hard disk to a larger (320gb drive). I would like to take an exact image of the smaller drive and put this on the bigger drive.
I'm trying to restore an image from a 40gb partition(6gb used) to a 100gb partition. I set everything up in gparted and and restored the partition image with clonezilla. In gparted, the partition shows the full 100gb partition with 6gb used, however when I boot windows and open the properties on the C: partition, it shows that it's only 40gb. Is there some setting to restore the partition image and use the full 100gb?
My parents bought a new hard drive for a laptop that I've owned for several years. It's much larger than the current one, so I plan on splitting it up to dual boot it with Ubuntu.I have no problem with partitioning a drive (I always keep a LiveCD handy), but my question is this: how can I go about moving the existing partition to the new drive? This is a laptop, so I can't simply plug the new drive into another slot.
Also, even if I manage to move it, will Windows still work on the new drive in a larger partition? I've had this laptop for quite a while, and I've lost the recovery discs that came with it a long time ago. I also have a lot of software without CDs to reinstall them with. This makes not reinstalling Windows a high priority.
I'm looking for some help on this issue. I have an image (Windows XP) made with CloneZilla of a 160Gb disk (used space = 11Gb) and I 'need' to restore that image to a smaller disk (120Gb). In order to try everything out I created a virtual machine in VMWare. I've tried about every option available in CloneZilla without succes. The latest thing I tried was using dd to just copy over the partition to a created partition on the smaller disk but when booting I got:
Code:Booting...Error loading operating system.Then I thought installing the image to a disk with the same size, resize the partition with GParted and make a new CloneZilla image, but for some odd reason (typical to Windows) when booting I get a BSOD, impossible to read. The BSOD happens when booting from the disk with the same size, before resizing the partition. This also is a virtual machine.Can anyone point out what I'm missing? Or, if anyone has succesfully done this, how did you go about it?
I am looking for an Open Source software making it possible to make a disk image of an Ubuntu installation as well as a Windows XP installation.I have checked out Clonezilla which almost solved the problem. However, the disk to which you restore needs to be the same size or bigger. I want to restore the whole thingo a smaller disk than the original.I am considering getting myself an SSD disk which will be considerably smaller than the 160 gb disk I have right now. I need it to work for Windows as well. Unfortunately I can't get rid of Windows quite yet I often participate in webinars on GotoWebinar and they do not support Linux ...
Using Samba I have looked into the file that stores all my web sites, there were a few strange files that get larger and larger all the time. File names are _Za01716 and _Za01820, they are nearly 50mb in size now. I know these are not Log files so what are they and can I delete them?
I have a couple of gigs of png files, each with 5-7 photos on each file. Currently I am making 5-7 duplicates of the file, then opening each one in gimp, and cropping and saving each one. kind of time consuming. Does anyone know of a program that will let me split an image into multiple slices?
I am using 10.04 LTS Lucid, and I notice the free space of root is getting smaller and smaller.
Five months ago, there was about 3.9GB free space of root, but now it is only 1.6GB. I always run sudo apt-get autoremove and sudo apt-get autoclean every time the update is finished, and also use Bleachbit to clean the system, but both are useless.
I never faced such problem with older versions of Ubuntu, is there any measure to fix it?
I need to convert a .jbg image to something else more 'generic' (.jpg, .png) but i discover that thar format seems not to be supported by default. Searching i found that i need jbigkit, so i download it but know dont know how to make it work?
Oooookay, so basically the idea I have is that I would like to boot Windows XP over an AoE connection. This is no issue, however the problem comes when I want to have a single, read-only image as the base image and want to be able to boot multiple computers off this image.Licensing issues aside (let's assume that this complies with all licensing issues, or we can think of it as just a conceptual "how could we do this"), the basic issues are thus:Each boot of Windows will require a writable AoE device...The original disk image must be read-only to avoid changes in 1 boot affecting all boots(As far as I know) The AoE device must be a disk image, or some block device rather than a mounted file system (if this is not so, aufs could be used)So the long and the short of this, from what I can tell is that we need a read only device that we can write to.
At the end of a session, the changes to the device will be discarded, so these can be thought of as simple temporary sessions. This means that there is little concern with having changes to the original read-only image effecting the modifications to the "duplicate" images.
I would like to avoid duplicating the image for each instance, however if no solution can be reached then this could be a possibility (every boot, we can copy the image, give the fresh image to the new boot and remove when done)Optimally, changes to the filesystem will be written to a different filesystem (much like what aufs does, however as stated earlier, afaik aufs only deals with 2 mounted file systems, whereas we need the end result to be an image or block device)Sorry if I havn't explained this particularly well, however I've been trying to think of solutions, caveats and generally how to define the problem as I was writing. If you think that this idea is ridiculous because software x handles the problem better, I'd be very pleased to hear about it, but the basic requirement of temporary, network bootable windows xp sessions still applies.

I never faced such problem with older versions of Ubuntu, is there any measure to fix it? 1. There is not any .deb in the /var/cache/apt/archives. 2. The total content of /var/log is only 167.6 MB, that won't be a problem.
I have this function that is supposed to print draw the first image from a function then hide the rest of the images using 'display: none' however for some reason the boolean test does not seem to work on one of my servers however it works on another, is there some php.ini setting I am missing or can you see any issues with the following code:
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.
using the update maneger to update on ubuntu new linux images available 2.6.31-17 generic and after the download is complete both images exist in the grub menu should i remove them ? or just remove them from the boot menu ? and if so how could i do each.
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.
My recent install of 11.2/KDE on a laptop suffers from a strange misbehaviour of the compose key (I have declared the Windows and Menu keys as Compose). It appears that two different sets of composing sequences are active, depending on the application.
I have to explain that I use a lot of unusual characters on a regular basis and therefore keep adding more sequences to /usr/share/X11/locale/en_US.UTF-8/Compose. I have even redeclared a couple of predefined sequences to values that are more useful for me. All these work fine, for example in a terminal window (konsole or xterm) or in konqueror, or even in OpenOffice.
However, other applictions seam only able to handle the default set of Compose sequences. This applies, for example, to Firefox or Gimp. It does not matter whether they are invoked from the command line or from a desktop icon. I tried both the Firefox shipped with OpenSuse, and a download from mozilla.org: Same result.
I tried to delete other Compose files from /usr/share/X11/locale/* but it did not help. I wonder where the default rules are actually found after deleting all the Compose files, even if (for some reason) the locales have changed in these applications.
I have OpenSuse 11.3 with Gnome.I noticed that the compose key is set to Shift + Right-Ctrl as default. How can I change this? In the system / keyboard settings / options / compose key position I can set another compose key, but then it works additionally. The Shift + Right-Ctrl checkbox is of course unchecked.So how can I completely disable or change the compose key? And does this come from different compose key settings for XWindow and Gnome/GTK+?
I am trying to type German Umlaut letters on an English keyboard using kde 4.4. For some reason I seem unable to figure out how to do that (I have just recently switched to kde, was using gnome before). I have looked through various threads and the kubuntu wiki [URL], but can't get the compose key to work. In gnome I used to type "AltGr" plus "[" followed by a vowel and thus get my Umlaut - before I fiddled with the system settings this worked in kde, but only in firefox & Open Office (I assume they are gtk apps).
Since it did not work in Kmail, I went to the system settings, set up a ComposeKey (AltGr, but also tried rightWin), but it doesn't change anything for the kde applications. It only means that the old key-combination now stopped working in firefox and OO. In the system setting of kde 4.4 I can't see the options to enable xkb-options, but I assume the advanced options of the keyboard layout are xkb-options of previous kde releases. I unticked the box 'reset old options', but nothing changed. I type a lot of German text, so using a character map is not an option.
I was trying to follow instructions from here [URL]..community/ComposeKey but couldn't get ANYTHING to work and can't type any special character. According to the instructions, if no third level / compose key is selected, then AltGr switches to third level and Shift+AltGr to forth. So I leave them unchecked to get default behaviour and they trying to type something but no characters appear.
I then started to experiment with different checkboxes, setting third level to Menu and Right Alt, combining them with checkboxes in Compose key position group - with no success. Any ideas what is wrong with this?
For some reason thunderbird randomly decided to stop letting my dad reply to emails with attachments. He can reply to normal emails, but as soon as he tries responding to an email with an attachment thunderbird just shows this:
Note the cutoff toolbar -- that might be a seperate issue though.
It will then show the above for all emails he tries responding to until I restart thunderbird.
I have tried:
1. Running Ubuntu classic with no effects. 2. Moving ~/.thunderbird 3. Changing the theme to clearlooks. 4. Resizing/maximizing/moving the window.
I have not installed or removed anything, the last upgrade I did was a few days ago, a bunch of qt libs were upgraded, along with firefox and openoffice.
My dad really likes thunderbird, and he needs to be able to reply to emails. I suppose I can set him up with Evolution if I have to, but he probably won't like that.
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.
I am looking for an application that I can select different types of instruments and select notes to play, and then make different instruments play at the same time or specified time in the track, thus composing a complete music. I am not looking for connecting instruments to computer and recording them, but I am looking for something that can compose music without using actual instruments.
