  • How do I achieve lossless JPEG joining without truncation of partial MCUs?

    - by Karan
    I am working on a project for which I need to join thousands of JPEG images losslessly (I'm not talking about the Lossless JPEG/JPEG 2000/JPEG-LS formats here). Aforementioned images have varying levels of chroma subsampling (1x1, 1x2, 2x1, 2x2), resulting in varying MCU sizes (8x8, 8x16, 16x8, 16x16 px). However, in any given set of images to be joined together, each image has identical characteristics. For now, let's assume I only have 2 images. Image #1 (I1) is 256x256px in size and #2 (I2) is 239x256px in size. 2x2 subsampling is used such that MCU size is 16x16px. I2 thus obviously has partial MCUs at the right edge, since its width is not evenly divisible by 16. (I've read that so-called 'partial' MCUs actually contain the data for a complete MCU, but the image dimensions instruct the renderer to only display the relevant pixels and ignore/hide the extra ones.) Looking around for tools that could help me accomplish this, I came across a modified version of JpegTran, that contains an experimental lossless crop 'n' drop (cut & paste) feature. All the other apps I encountered that support lossless JPEG editing seem to utilise IJG's (JpegTran) code, so this seemed to be the logical choice. Also, given the sheer number of images, I wanted something that could preferably be run from the command-line so that I could automate the process with a script. Unfortunately, while everything else worked fine, it seems JpegTran truncates the partial MCUs instead of retaining them. Thus in the example above, the final joined image contains all of I1, but only 224x256px of I2. Why 224? because 239 = 14x16+15, which means there are 14 full MCUs along the width, and 1 partial MCU (just 1px short of the complete 16px). The last 15px is what is getting blanked, leading to a 495x256px image with 15px of blank (grey) pixels at the right edge. See images below (shame that imgur re-compresses them): (left )+ (right) = As you can clearly see, the red portion (15px) of I2 has been truncated by JpegTran. If the MCUs were 8px in width, the lost portion would have been the right-most 7px of I2. Similarly, joining I3 (256x239px) *below * I1 would cause the loss of 7 or 15px, depending on the MCU height of course: (top) + (bottom) = If this is better suited to some other StackExchange (or even non-SE) site/forum where JPEG/image encoding experts hang out, do let me know. Can what I am attempting even be done, or is the so-called 'lossless' JPEG crop 'n' drop only valid for images with no partial MCUs? (Maybe that is why the feature is still in an "experimental state" more than a decade after being introduced...) Until I know for sure that it is impossible, I am not interested in suggestions for lossy joining. Avoiding any generational loss whatsoever is the sole reason why I'm breaking my head over this, else I'd have had this done and dusted ages ago. Also, I am not interested in suggestions related to switching image formats. I do not control the source of the images. If it can be done, how? Please keep in mind that any alternate apps suggested must ideally be capable of automation, given the requirements stated above. (But given how it's unlikely I'm even going to receive a useful answer given the constraints, I would be happy with any app suggestion just as long as it actually works. I can always look into an AutoIT/AHK script or something later to automate it.) I understand that an odd-sized final image might cause issues, so I am fully prepared to accept any solution, even if it results in blank (preferably black) padding pixels to the right/bottom. What I mean is, I don't care if I1 + I2 is 496x256px (1px padding) or even 512x256px (17px padding) in size, as long as the final image contains all the actual image data from both source images, and the entire process is lossless. Obviously the lesser the padding (if any), the better, but at this point any solution will do. A Windows-based solution would be perfect, but a Linux-based one would be entirely acceptable.

  • Samsung 530U3C clean system installation

    - by user1292810
    I have bought Samsung 530U3C notebook with i5-3317/12GB RAM/500GB HDD/24GB ExpressCache/Windows 8 preinstalled. I would like to install my own clean version of Win8. But I would like to preserve recovery partition. I will sell this laptop in probably 1-1.5 year and I would like to be able to restore settings to factory ones. What is more, in the future I would like to install Ubuntu as well, but Windows goes first. At the moment discs and partitions looks like below (sorry for non English screen): http://i.stack.imgur.com/p4W6t.jpg DISC 0: 500MB - recovery partition 300MB - system partition 442.22GB - Drive C: - Boot, Page File, Crash Dump, Primary partition 21.64GB - recovery partition 1.00GB - recovery partition DISC 1: 9.00GB - primary partition 13.24GB - primary partition Which partitions can I format and which of them should I preserve? Can I format and merge partitions from that 24GB ExpressCache and install Windows on it?

  • Why do I get error 0x0070004 when trying to update to Windows 8.1 from Windows 8?

    - by Jeffrey Lin
    So, I'm trying to update Windows 8 to Windows 8.1 via the Windows Store, but every time I attempt to, the update downloads properly, but then I get the error: Windows 8.1 This app wasn't installed - view details When I click on it, it says: Something happened and the Windows 8.1 could not be installed. Please try again. Error code: 0x80070004 Try again Cancel Install What does this mean? A quick Google search yields nothing. I have tried rebooting, clearing the store cache, and resetting Windows Update. A quick chkdsk scan shows no errors. A SFC scan shows that there are many issues. http://pastebin.com/TZiH8ZXZ Could this be the issue? I found the error log! http://pastebin.com/BXZEsejm Why is the registry corrupt?

  • VMWare Fusion: "No Permission to access this virtual machine"

    - by Craig Walker
    I had a VMWare Fusion VM backed up on my home network file server (Ubuntu). I wanted to run it again, so I copied it back to my Macbook. When I tried to launch it in VMWare, I got an error message: No permission to access this virtual machine. Configuration file: /Users/craig/WinXP Clean + Scanner.vmwarevm/WinXP Pro Test.vmx The permissions look fine to me: The bundle directory is 777 The bundle files (including the listed .vmx) are all 666 User is craig (my current user); group is staff. I changed the group to wheel at the suggestion of this page, but that didn't help. Finder shows read & write for craig, staff, and everyone on the bundle directory The bundle dir is also not locked Finder also shows rw and unlocked for the .vmx file The parent directory is also rw & unlocked Disk Utility permissions check doesn't show any problems with any of the associated files It sure looks like I should have wide open access to run this VM; why is Fusion complaining?

  • Can't add a network printer - Windows 7

    - by r0ca
    Hi all, I have an HP 2600n installed on a SBS2003 server. This printer works fine when I print from the server itself and also from my Windows 7 computer #1. From my Windows 7 #2, it doesn't work. I get the error message that I need to install the driver. The error message is in french but here it the translation. No drivers has been found Windows is unable to find a driver for HP Color Laserjet 2600n on the network. To find a driver manually, click ok. If not, click on cancel and contact your sys adm. I reinstalled from scratch the printer, deleted the driver... Still no luck Any takers?

  • i5 vs. i7 processor dev laptop

    - by vector
    Greetings! I need to get a laptop for dev work ( mostly server side Java, NetBeans ) and wonder if anyone had a chance to use either the i5 or i7 based laptop? Is the i7 an overkill? ... or will the i5 handle it just fine? I'm thinking something from the HP line running Ubuntu. Thanks

  • Are all bluetooth adapters the same ?

    - by ldigas
    I have a wireless bluetooth mouse which I'm not using. It used to have a bluetooth adapter with it, which I lost a long time ago ... (don't ask). Since my regular mouse just died (bad contact in cable from messing with it too much) I was thinking of buying just the new generic bluetooth adapter ? Are all those adapters the same thing ? Or can this that came with the mouse be somehow different ? Edit by ldigas: How would one find out what bluetooth standard/class/adapter one needs ? (I don't see anything useful written on the sticker on the mouse). Or to put it bluntly - will it work with this one in your opinion ?

  • Bash: Reset and Clear Commands

    - by sixtyfootersdude
    I have been using the command: reset to clear my terminal. Although I am pretty sure this is not what I should be doing. Reset, as the name suggests resets your entire terminal (changes lots of stuff). Here is what I want: I basically want to use the command clear. However if you clear and then scroll up you still get tonnes of stuff from before. In general this is not a problem however I am looking at gross logs that are long and I want to make sure that I am just viewing the most recent one. I know that I could use more or something like that but I prefer this approach.

  • What is the data transfer speeds within the disk, to other devices?

    - by Kumar
    I use Debian 6 on a HP Elitbook 6930 with 2Gigs of RAM. I was copying two AVI files, 1.5 GB in total, and noticed that the data copying was done at the rate of 4MB/sec. When I copy same AVIs to my Western Digital Passport 25G USB plugin drive the data transfer speed is 11+MB/sec. This speed is different if I plugin the drive to different USB ports. Interestingly, at work I also downloaded a 16MB IE8 exe on my virtual xp, run inside Oracle Sun Virtual Box, and it was downloaded AND saved within a second. We have a high speed network at work. :-) Why and how this difference in data speeds is possible?

  • Disable "longhaul" kernel module with a GRUB command?

    - by Julian Schweigert
    I've got a problem with a VIA C3 (1GHz)-system: the system freezes immediately when the CPU frequency goes under 731MHz because of an incompatibility with the (not completely implemented) i686 commands and a powersave feature of the kernel. There is a workaround: deactivate the "longhaul" kernelmodule via alias longhaul off in /etc/modprobe.d/aliases. But the system freezes before I can install any Linux distribution - even Clonezilla freezes. Is there a possibility to deactivate the module with a GRUB boot parameter before the kernel is loaded?

  • Mac OS X Update 10.6.8 weird phishing behaviour

    - by Carlos
    I just updated to Mac App Store 1.0.2 with the update to 10.6.8. The Mac App Store said I have one update available, for Angry Birds.... I do not have Angry Birds on my system, but when I clicked the update button I got the following message. "You have updates available for other accounts. Sign in to [email protected] to update applications for that account." Needless to say this account does not exist. Any ideas what this is all about?

  • Update to Lion, Cannot boot into Bootcamp partitions, but can use in Parallels

    - by Jon Jester
    Using Snow Leopard had boot camp partitions for both XP and Windows 7. These were both accessible through Parallels 7 or through direct boot through boot camp. Each is on a separate partitioned hard drive. Upgraded to Lion, both were still accessible through Parallels, but have not been able to directly boot into either. Unfortunately is important to me to be able to boot into a least the Windows 7 partition. Have tried virtually everything I can find online. Seen similar issues, but nothing where they were usable virtually but not directly. Nothing works. reFit, correcting the master boot records in Windows with command line, have wiped the Windows 7 partition clean and reinstalled Windows 7 several times 1st using Boot Camp4 drivers then using Boot Camp3 drivers. Have tried resizing the bootcamp partitions. When booting into the Boot Camp partitions directly will go all the way to seeing the desktop before it fails, where I get a Windows error screen. I can see all the disks and their appropriate partitions both in OS X disk utility as well as the Windows installer utility.

  • Fedora 16 can connect to samba share using smbclient but not in nautilus 3.2.1

    - by Nathan Jones
    I have a machine running Ubuntu 11.10 Server acting as a Samba server to share my home directory. Everything works fine on my Windows 7 machine, but on my Fedora 16 laptop, if I use Nautilus to try to access the share using smb://192.168.0.8/nathan in the location bar, it just has the loading cursor and does nothing. It never shows any errors, nothing. Using smbclient works just fine, but I'd like to get it working in Nautilus.

  • How do I install rubber pins onto a case fan?

    - by Resorath
    I have the following rubber pins with my new case fan: I'm not sure how to install these. They are obvious to install into the case, the rubber pulls easily into the screw hole and stays in place, however the fan they came with they do not seem to fit in the screw holes at all. I put the thin side into the fan and pulled so hard that it actually snapped the rubber, so obviously that is not the correct method. How do you install these rubber pins into stubborn fans of which they were designed for?

  • Fixing Windows 7 hibernation

    - by 80skeys
    I've been mucking around with the partitions on my laptop (I'm an experienced Linux/grub guy) and have somehow ended up affecting the ability of Windows 7 to go into hibernate mode. All other functionality seems to be okay. But when I press Hibernate, it behaves as if it starts to (screen goes dark, a little disk activity) but never powers off and if I move the mouse the login screen instantly comes up. I don't know if Window uses a separate partition for hibernation? There is a 200MB partition on the drive - I seem to recall it was related to diagnostics or some other Windows- boot menu stuff. In any case, wondering if there's some commands I can run to restore the ability to hibernate and also which partitions need to be marked "active" and if there's anything I need to do to the MBR of the hard drive or the MBR of the Windows partition? As I said, Windows boots fine as long as it is designated the Active partition. I just need to fix Hibernation.

  • Local, Multiple-Blog (ie Dashboard) Blogging Software as Alternative to Blogger [closed]

    - by Synetech inc.
    FOR RE-OPENING: I don’t see how it is “too localized”. Plenty of people like to run their own web-apps instead of relying on third-party services. If that were not true, then WordPress, phpBB, Apache, PHP, etc. would not be available for general use. As for “Internet audience at large”, I must have missed the part where it was a rule that you are only allowed to ask for help for things that applies to everyone else too; I thought you were allowed to ask for help. Besides, if someone knows of software that fulfills the question, then it is relevant to whomever would download it, and so is not only applicable to an “extraordinarily narrow situation”. (Besides, the reason that I was asking was because Google had announced that it was discontinuing FTP support for Blogger and so many people were affected—read NOT TOO LOCALIZED—and were trying to find alternatives.) Hi, I am trying to find software (for Windows, PHP, MySQL/SQLite/flat, free, open-source) to localize all of my software and service so that I can keep my files and host when needed from my own system instead of some remote computer. I’ve already selected things like web, FTP, and db servers. I’ve chosen forum and wiki software, as well as an RCS system. At this point, all I’m still looking for—actually, I still need to choose bug-tracking software, but besides that—is blogging software. I still use Blogger and am trying to find something that I can use to import my Blogger stuff and store on (and publish to) my home system. I have read of various blogging software including WordPress, MovableType, and TextPattern. The problem is that I am trying to find something that is like Blogger (which from what I can tell is not available on Google Code as open-source). What I specifically need is multiple-blog support. That is, multiple blogs ala the Blogger Dashboard, not multiple user accounts (although that is important as well). The closest thing that I have been able to find is using Wordpress categories to simulate multiple blogs, but that’s not really what I want. I want software that I can run locally that has a multi-blog dashboard like Blogger. Any ideas? Thanks a lot!

  • RAR Password recovery / hash extraction on Mac OS X

    - by Josh K
    I'm running Mac OS X 10.6.2 and have been handed a couple of old files that need to be extracted. Old backups or finances or bills I believe. They are RAR files, and password protected. Is there a way to extract the hash from these files so I can feed it into John The Ripper or Cain and Abel? Edit I have downloaded cRARk, but unfortunately nothing I have (SimplyRAR, RAR Expander, The Unarchiver) will extract it without a password. Can someone verify that I'm crazy and there is no password on the Mac version?
