What are the techniques of compression permitted for PDF/A-1?

The PDF/A-1 standard does not specify how the compression is performed. What are the techniques of compression permitted for PDF/A-1?

The information that I have collected (not sure if all are true)

  1. LZW should not be used
  2. JPEG2000 may not be used
  3. Some say, JPEG can be used, but it's a lossy compression. (Standard PDF clearly indicates a lossy compression cannot be used)

How to determine if a particular file is PDF/A-1 also or PDF/A-1b and what type of cuts are used in this file?

Thanks in advance.

Adobe Acrobat Pro provides preflight profiles to test if a PDF conforms to a PDF/A or PDF / X standards. There are also options to convert a PDF file to one of these standards if these corrections are possible.

FYI, there are specifications for the various PDF/A and PDF / X specifications that you can buy (on paper or downloadable PDF files) of the ISO.

  • What are the size of partition recommended for installing Windows 7 Professional 64-bit?

    What are the size of partition recommended for installing Windows 7 Professional 64-bit? I have a 2 TB internal hard drive and want to install Windows and Norton Internet Security on the drive C, drive D and drive E data programs.

    Thanks for a response.

    Original title: size partition Windows 7 Professional 64 bit

    For technical purposes, I recommend you only keep utilities all programs that you install on the startup disk. This is recommended if you plan to upgrade to future releases of Windows such as Windows 8 because you will experience problems with the installation program.

    I recommend however, you can keep accumulated data such as Documents, Photos, music, videos on a separate partition to ensure custody.

    The recommended size for the boot drive around things like Windows, future growth for applications and the Windows updates and program updates will be considered.

    So I recommend not more than 200 GB, for a lot of space, I would shoot up to 300 if you want to keep things like System Restore Points.

  • What are the requirements of optimal hardware for Adobe Photoshop CS6 specification?

    I greet the staff and users of this forum,

    As the title makes clear, the issue is "What are the requirements to the optimal hardware for Adobe Photoshop CS6 specification".
    Unfortunately, I am not satisfied with the specifications indicated on the site, because I think that they are much less important than the specifications needed to run the program to its full potential. This belief comes from my experience with the Adobe Photoshop CS2 product that I currently run on my computer. Indeed, Ps CS2 can not fully execute without causing shifts in time on my computer (i.e. when using smudge diameter of 500 pix / help to liquefy Gallery), even though my characteristics are already higher than those specified for the CS6 (mine are: Intel Core 2 Duo 6300 1.86 GHz, 3 GB RAM). I can assure you that I receive these shifts in the time almost in SafeMode (only key running system processes) and that my computer is clean of any virus/process that could reduce its performance.

    I lived two forums and four telephone operators to always get the same answer: the specs on the website.
    If any user here could give me a more accurate record, I would be really grateful.

    Thank you

  • What are the features of Mozilla Firefox for Linux?

    I found an article about Firefox Desktop features. Linux and Windows have the same characteristics?
    If this isn't the case, I need to know the characteristics for Linux.

    Firefox for Windows, Mac OS x (10.6 +) and Linux (from mozilla.org) are pretty much the same.

    You can find some of the shortcuts from the Menu and KB is a little different on the three operating systems because of their BONES in the Human Interface (HIG) guidelines followed. May also have small differences in appearance.

    For example, tools-> Options on Windows is Firefox-> Preferences on Mac and editing-> Preferences under Linux.

    Adobe is kind of screwing with Flash by Linux users only supported Flash 11.2 with security updates.

  • What are the best settings of catalog for long-term use?

    I have 5 Lightroom and like many people, I learn that I will.  But I currently trying to manage the photos, without any sense real cataloguing and now Lightroom moves slowly in the mode of development.

    Question #1...  These issues are related?

    I don't know if it's available using catalogues, but I would like to have a system of Lightroom that allows me esaid and particular export shoot and then 'REMOVE' from Lightroom completely, without losing the edit history and allowing me to add additional changes (in the FUTURE) if necessary. 

    I don't see a characteristic of the SKIN.

    Question # 2... Is this available through the catalog system?

    Can "re-import you" story edition?

    Can effectively "HIDE you" a Photo folder or I guess... According to my original question... can 'HIDE you' a catalogue of photos?


    Background:

    I don't know I need to set up the catalogs now, but don't want the hassle to guess how best and learn I did a big mistake later or make a choice of cataloging that will cost me later.

    I only 6100 images in Lightroom now, but I would add an average of 200-300 per week. Sometimes much less... Sometimes even more.  200 images, I'm probably the only edition of 50, but I like the idea of having the stem (except for the absolute terrible shots) all available for future review or edition.

    As slow as the activity is, photography is a new job for me, so I'll just do more years forward.

    Thanks in advance for your suggestions as long as "layman's terms" and possible.

    John

    If you do not back up your catalog on a basis regular then you are walking on very thin ice. If this catalog is damaged, or if your computer breaks down, you get the idea, you will lose all your work. Why don't you back up your catalog? This is the file that stores all of your changes, your whole story, is absolutely essential for the functioning of Lightroom. Are you ready to throw all your work? Part of the backup process optimizes the catalogue, which could contribute to the performance of compromise. But I would look at other opportunities as well. You can try to delete your preferences file to see if that makes a difference.

  • What are the options for 3 bit for Hw_Arm_Sel in PCI-6601 field

    Hello

    I'm programming our own driver to operate the PCI-6601. For our application, we need option arms material. I know, it is possible to use 2 counters for this, but NEITHER-TIO also supports hw_arm. Although it is not explained in the registration document at all, after some tedious verification in the DDK examples I found that the pieces are in the Gi register metering mode. I know that the position of the HW_enable as well as the position of the 3 options sellect bits PIN. What I don't know is what are the options of 3 bits for Hw_Arm_Sel field. I contacted the support NEITHER, but received no support. How can NEITHER sell boards and when a customer who doesn't use LAbview or Measurement Studio, or DDK, but implements its own driver is then so arrogant at least of NOR? Also, how can OR publish only a part of the records of the Board of support and when a customer contacts and request for some records do not get supported at all? I can't predict the missing records, and he is professional enough to document comes in part from records of 660 x Instruments. And, upon request, you have nothing.

    I hope that someone from the community are aware of this Hw_Arm_Sel 3 pin option. Otherwise, there is just one option of the error and the trial. Or simply throw away the jury.

    What should be the parameters when I do a new sequence?

    When I look into the window in Premiere Pro I constantly have to "shrink" the image to fit the window, is that something I should do or he says that the configuration of the sequence is bad?

    But more importantly what should be the parameters of export? I exported a long video of 4 minutes and the size was 1 GB, I know that it's too big.

    I need to export without losing quality and export another one which is consistent with the limits on the size of Youtube and Vimeo.

    Vimeo is 500 MB per week, sometimes I download 4 videos per week. I think that Youtube, you can download 500 MB at a time.

    I need to get the smaller size with lose the least possible quality AND the best export quality settings, so I suppose I have 3 separate issues.

    What are the best settings of sequence for HD video?

    What are the best export settings for HD without losing quality?

    What are the best export settings for the size of out about 500 MB with losing the least possible quality?
