How to convert 16-bit to 8-bit without dithering

I have 16-bit TIFF of RGB that I need to convert to 8-bit Windows bitmaps.

When I Image > Mode > 8 Bits/channel, introduced Photoshop dither.  He doesn't want.  He's just doing.

Of course Photoshop erode try to simulate the fine 0-32768 for 16-bit tiff with 0-255, rude to the 8-bit bitmap.

But the nature of my photos do not dither.  He cannot have pixels that are identical to the neighbouring pixels have become true.

So I want the simplest kind of 16-bit conversion to 8-bit - pixel by pixel - each 16-bit level is replaced with the level of 8 nearest bits.

If there is no way to disable the dithering in Image > Mode > 8 Bits / layer is there some other way for the bitmaps in 8-bit necessary?

Thank you

.

Create a new 8-bit doc and copy the original 16-bit file to the new RFSO bit using the copy (or merged copy) and paste.

Save for web strips almost anything but the image of the file data. Probably better to copy and paste If you need dithering for color space conversion, or do as suggested and change the color settings.

Save for web (and devices) is in the file menu.

    Pls answer my qus...

    You will need to do a clean install, there is no place on the way to upgrade Windows 7 32 bit to 64 bit.

    Using the disk of 64-bit Windows 7, install Windows 7 Windows Easy Transfer Utility from the DVD (to find it, simply navigate to x:\support\migwiz, "x:" is the name of your hard drive. (In this case, you will see a collection of files, the important"that you must search for and double-click is 'migsetup'.) run it and create a DAMP (Windows Easy Transfer file), if you have an external hard drive, you can access it later when you perform a clean install of Windows 7 64-bit disk so you can stored there.

    Once you have done this, just do a clean install of Windows 7 64 bit disc. In Windows 7 64 bit disk, start Windows Easy Transfer, follow the wizard screen, tap on which is stored the WET file (external hard drive) and it will restore your personal files and settings. Reinstall the applications needed.

    http://www.notebooks.com/2009/10/07/using-Windows-easy-transfer-in-Windows-7/

    Boot from the Windows 7 DVD
    Click Install now
    Accept the license agreement
    When the option is displayed to select a type of installation, click (Custom advanced)

    Select the disk partition where you want to install Windows 7 click Next.

    You will receive the following warning:

    The partition you have selected may contain files from a previous Installation of Windows. If so, these files and folders will be moved to a folder named Windows.old. You will be able to access the information in Windows.old, but you will be able to use your previous version of Windows.

    (At all costs, do NOT click on anything in Format, deletion or Partition name.) So even do a custom installation, your personal files are still kept. Click OK

    The installation program will now begin installation. During installation, your computer will be restarted several times.

    Once the installation is complete, you can complete the Out of Box experience as the choice of your laptop, create a username, password, your time zone. You can then proceed to download the latest updates for Windows and reinstall your applications and drivers.

    You can then retrieve your personal files from the Windows.old folder and reinstall all of your applications and drivers.

  • How to convert a Tiff image to JPEG without being FORCED to 8-bit color?

    I'm an artist.  I have high quality TIFF images.  When I convert TIFF to jpeg it make me color 8-bit automatically. (Forget about 32 bit - it does not in jpeg format that at all)   The only way that I can return to the 16-bit color is to use the already broken file and bring it up to 16 bits.  IT makes NO sense at all.  Once the jpeg format is broken, how is the world supposed to convert back to the top. ??  So even though it says that you have converted the 16 - bit file, metadata is always about the 8-bit file.

    In addition to en plus de tout all this confusion, an image, for example, in the case of so-called converted to 16-bit, gets a lot grow so even the original Tiff image.  It looks good on the one hand and more exposed on the other.  I guess that's throwing in resolution photoshop fake, I'm good?

    I'm wasting my time with this 16-bit imaginary conversion?

    Is it possible to take the original Tiff image and convert default 8-bit to 16-bit jpeg without value?  I tried all sorts of things.  I even asked my web guy.  My web guy said only 8 bits is unexceptable for printing, same for the web.

    Would this have something to do with my computer and the scanner?

    I have the memory of 8 GB iMAC OS X 10.8.3 (3.2 GHz).

    And I also have a capable graphic arts Epson Expression 10000XL scanner from scanniing to 48-bit color.

    This color stuff is really important!  This is IMPORTANT!  I have files FINE art.  I'm already losing so much quality with jpeg conversion. (which I am required to do for SmugMug, in addition to the compression of all my files of 50 MB or less)

    Anyone who knows anything that could help me would be much appreciated.

    Aloha,

    -Melissa

    First jpeg is 8-bit only it there's no way to register as a 16 or 32-bit jpg, just does not exist. Secondly people print in 8 bit all the time and most if not all web graphics are 8-bit because this is the only way to see because there is no 32-bit or 16-bit monitors to see. All pro monitors are 8-bit monitors.

    If you like on the color range and want the range of colors that provide 16 and 32 bit, so why jpg? Jpg by his own nature throws of color just to compress, why it is popular on the web, because of its small file size not its quality. If you need 16 or 32-bit for what it is, it must be in a format that supports this color depth.

    That being said, that a jpg to 8 bit image displays 16 million colors, 256 shades of red, 256 shades of green and 256 shades of blue.

    Now, here's where I think your information bit is disabled. a jpg image is a 24-bit image that will produce 8-bit red, 8-bit, 8 bits of blue and green.

    8, 16 and 32 channel are not total not the color information.

    If the overall picture was of 8 bits, the image would be gayscale.

  • How to record a bit 2D array in .bmp file?

    Hello

    I'm new to LabVIEW...

    I have a 2D binary table and I want to record to file .bmp. The .bmp file must be 1-bit bit depth in order to satisfy the devide requriement.

    I tried to use flatten pixmap , but there only 4-, 8 - and 24-bit pixmap options for table 2D. 1-bit pixmap is for Boolean table entry.

    I don't know how to convert the bit 2D array in the array of Boolean or any other method to resolve this problem.

    Thank you are to help.

    Thank you

    Hi Jinyang,

  • How to convert U32 matrix 8-bit grayscale image?

    Good day to all,

    I got a U32 512 * 512 data table of photomultiplier using the analog inputs of the DAQ card. My question is how to convert this matrix 32-bit to 8-bit monochrome image for display.

    I tried the method in this post to convert grayscale image https://decibel.ni.com/content/docs/DOC-4155 table but the result resembles an outline rather than the actual image. I guess that's because their contribution to flatten Pixmap is 8 bits, but mine is 32-bit. I have a gamma correction to the scale of my data? But how?

    I have attached the original image, which is a particle. I have also attached my labview code and the processed image.  Thank you!

    Then, you will likely make you own custom conversion then increasing the difference between the brightest and darkest. You could just do 4294963840 the zero and 4293967276 the max and scale up to 0-255

    How can I convert 16-bit files to 8-bit in 5 Lightroom?

    You can actually convert a 16-bit image to 8-bit using Lightroom image. You can export a copy and make the copy an 8-bit image. Lightroom does not change the content of the image or makeup. The images that you import into Lightroom are kept in State of origin. But you can export copies in different configurations.

  • Is there a simple way to convert the bits to 16 bit depth?

    It seems there are specific methods PDF/BITMAP to convert 8-bit depth, but I can't find any documentation to make it easily the file as a whole. Is there a way to do this? I want to convert from 32 to 16 bit.

    I have the Image Processor Pro code that looks like this:

      // Bit Depth
      var bd = toNumber(task.@bitDepth) || 0;
      if (bd) {
        var bpc = doc.bitsPerChannel;
        try {
          if (bd == 8) {
            doc.bitsPerChannel = BitsPerChannelType.ONE;
          } else if (bd == 8) {
            doc.bitsPerChannel = BitsPerChannelType.EIGHT;
          } else if (bd == 16) {
            doc.bitsPerChannel = BitsPerChannelType.SIXTEEN;
          } else if (bd == 32) {
            doc.bitsPerChannel = BitsPerChannelType.THIRTYTWO;
          }
        } catch (e) {
          LogFile.logException(e, "Error selecting bit depth " + bd);
        }
      }
    

    Then, later, I have this code that modifies the document mode so that you can save it as a bmp file:

      if (ImageProcessorOptions.JDI && ext == "bmp") {
        // We need to make adjustments depending the number of
        // bmp save bits selected
        if (saveOpts.depth == BMPDepthType.ONE ||
            saveOpts.depth == BMPDepthType.SIXTEEN ||
            saveOpts.depth == BMPDepthType.TWENTYFOUR ||
            saveOpts.depth == BMPDepthType.THIRTYTWO) {
          saveOpts.rleCompression = false;
        }
        if (saveOpts.depth == BMPDepthType.FOUR ||
            saveOpts.depth == BMPDepthType.EIGHT) {
          doc.changeMode(ChangeMode.GRAYSCALE);
        }
        if (saveOpts.depth == BMPDepthType.ONE) {
          if (doc.mode != ChangeMode.BITMAP) {
            doc.changeMode(ChangeMode.GRAYSCALE);
          }
          var cnvtOpts = new BitmapConversionOptions();
          doc.changeMode(ChangeMode.BITMAP, cnvtOpts);
        }
      }
    

    I don't think I've tested with PDF files.

    I hope this helps.

  • How to make Windows 7 32-bit to 64-bit without the new windows installation 7

    32-bit to 64-bit without the new windows installation 7

    Moving from 32 bit to 64 bit Windows 7 always requires an own (custom) installation of Windows 7.

    Since this is a clean install of Windows it takes you will need to backup your personal data (documents, pictures, music, etc. on a separate drive). You should also make sure that you have installation media, and product keys available to reinstall your programs.

    Most, but not all Windows 7 32-bit programs will be running on Windows 7 64 bit. Check the support of publishers of program site compatibility.

    32-bit and 64-bit drivers are not interchangeable. You should make sure that your hardware has drivers 64-bit available.

  • How to convert wma to mp3 on external hard drive file

    I have a new version of osxe1 mac 10.11.2 capitan how to convert wma files into mp3 files that are on my external hard drive so my mac can copy on my iTunes

    http://www.mediahuman.com/audio-converter/ - free.  Says it does WMA. I have not used it so try at your own risk...

    Switch (free basic version) - http://www.nch.com.au/switch/index.html - I don't know if this will make WMA

    All2Mp3 - http://download.cnet.com/All2MP3/3000-2140_4-190407.html - limited success with WMA

    Flip4mac - need version payware intermediary that allows you to convert.  Use with Quicktime player.  Flip4Mac - http://dynamic.telestream.net/downloads/download-flip4macwmv.asp?prodid=flip4mac wmv - the free version will allow QuickTime play, but not to convert Windows Media files.

    After installation, a new component of Flip4Mac will appear in system preferences.  Make sure that you set the boxes to make sure that it will play WMV files in Quicktime format.

    VLC - not really a converter but will do a bit on the menu export.  Can be slow to be converted and there will be a learning curve.

    Explore online converters when you download a file in a format and download in another.

    I do not know if your computer can run Audion 3 I think I used to use it to convert WMA.

  • How to convert wdb and xlr files?

    I have Vista Home Premium 32-bit.
    How to convert files from 2003 (Windows Me) on my backup.
    They are important. Some have extensions wdb or xlr. I have Office Word Viewer and Open Office.org, but I can't find a way.
    Does anyone know how to open these files?
    Thank you

    Hi sail,

    Extension WDB is works database file.

    XLR files are spreadsheets or graphs created within the 'Œuvres', XLR files are totally unwearable in Microsoft Excel, however, Excel spreadsheets are not totally compatible with works and some properties of the cell or characteristic data may be lost when you import Excel spreadsheets in the works.

    You need their respective requests to open the file or you could get some third party tools using your favorite search engine, which will help you convert WDB file in word (DOC) format and XLR files to import to Excel.

  • How to convert wma and wav, mp4 files and what not not mp3 with Windows media player?

    * Original title: music questions

    Music has become a huge problem for me.   My car CD player only supports mp3 format.  I wish I could burn my CD from which I get used various locations, so that I can play in my car. Or convert files I have, which are not in mp3 format.  I played the same CD in my car for years.  It's a little sad.  And convert mp3 no mp3 files, so I can play them in my car, because I don't have a player other than Windows media player and speakers belong good markets.   How to convert files to wma and wav and mp4 and what not in mp3?

    Music is expensive nowadays and the multiple formats and thus loss of music bought and in the cloud, or itunes 'cannot locate the source' will not play, and when devices in the event of a failure or who are upgraded drives me crazy.  I have more music in my life and I wish that we would go back to portable music as CD.

    I usually use Windows Media player to RIP CD, that I find at thrift stores.   I have my brother gave me, on the PC that is in all sorts of types of music files.  I found a job online converter and it is, according to me, so thank you guys for suggesting that.  Have tried 3 different ones and finally found one that works in the last one.  I think my brain might need a bit of adjustment, of our days, (won't tell you music I have on CD, would seriously date), no kidding, but probably my PC could also use the setting.   I also have itunes for Windows, but have hardly used it.

    How to convert a layer back to the text "T? He is currently uneditable and I want to change the font (also, how what happened?).

    According to your layers panel. The top layer is a text layer years the second layer is a raster layer. A raster layer once the case has been closed, cannot be cancelled. It will have to be re-created. If for some reason, you left the file open, then it is perhaps possible to cancel it, because it would show in the history stack. But by default that stack is set to 20 States, to more than 20 he would push the battery.

    I think that you have to bite the bullet and redo this layer.
