How to make a Histogram from a BufferedImage?

Hi all,
I am wondering how I can make a Histogram from a BufferedImage - I'm looking for some sample source code on how to this, since I have never worked with the Histogram class before. I need to know how to implement and use Histograms.
I'd be greatly appreciative if anyone could help-out a fellow programmer.
Cheers

TestStand does not have these functions.
You can store all the values in database (enable option) and use either CVI or LV to display it.
How are you displaying it using a VI and how much time does the VI take to display it?

    How do I make a silhouette from a portrait?
    Ah, but wouldn’t it be ever so much easier to explain if you actually provided (a lores of) the image in question?
    And how do I make the background transparent?
    Preferably with a Layer Mask and then saving in the appropriate file format (psd or png24 for example support transparency).

  • How to make bootable iso from download

    how to make bootable iso from download

    This one - https://www.microsoft.com/en-us/download/details.aspx?id=5587
    1st:  This is NOT a .ISO file!!
    2nd.  It is a .MSI file which is a Microsoft Installer file.
    3rd:  Read the instructions:
    Install Instructions:
    Click the Download button to start the download.
    Do one of the following:
    To start the installation immediately, click Run.
    To save the download to your computer for installation at a later time, click
    Save.
    To cancel the installation, click Cancel.
    When installation completes a file called readme.txt will open to provide instructions for burning a home computer restore CD. The file is also located
    next to the ISO image file for later reference.
    4th: If you are unable to read and follow instructions, there is nothing anyone in these forums can do to assist you.  You must be capable of reading and following instructions! 
    Please remember to click “Mark as Answer” on the post that helps you, and to click “Unmark as Answer” if a marked post does not actually answer your question. This can be beneficial to other community members reading the thread. ”
    OK, well sorry to disagree with you but:-
    1. Using windows 7, the download does not provide a save but only a run option.
    2. In the MS predownload instructions you copied it refers to the readme text next to "the ISO image"
    3. This is a copy of the read me file attached:-
    "This ReadMe document is one of the Windows Home Server Home Computer Restore CD files. Unless you changed the installation location during setup, the Home Computer Restore CD files and license terms are located in one of the following folders:
    * On Windows Vista: %HOMEPATH%\Documents\Windows Home Server Home Computer Restore CD (Dual Boot)
    * On Windows XP: %HOMEPATH%\My Documents\Windows Home Server Home Computer Restore CD (Dual Boot)
    To use the Home Computer Restore CD software, you must write the ISO image file (restorecd_dual.iso) to a blank CD. A CD/DVD burner is required to write
    the ISO image file to the CD. Usually a CD/DVD burner includes the software that you need to write ISO image files. Follow the instructions with your burner software, and then select the option to write an ISO image, not the option to write
    individual files. Note that you cannot write the ISO image by using Windows Explorer to copy the file to the CD-ROM drive.
    Burning the ISO image creates a bootable CD. To restore your home computer, boot the computer from the CD and follow the instructions.
    Microsoft may update the Windows Home Server Home Computer Restore CD software. You can download the latest version from the Microsoft Web site at http://go.microsoft.com/fwlink/?LinkID=109282.
    If you want to review the license terms for the Windows Home Server Home Computer Restore CD, the file EULA_DUAL.TXT can be found in the same folder"
    As you will see it refers to the downloaded .iso file. Nowhere is there a reference to a msi.  As there was only a run function on the downloaded file, it could not be saved. How is an ordinary Windows user meant to interpret the instructs
    if the download function does not work? What you do is try and follow the instructions and produce a load of frigging coffee mats, as it seems did many of the posters on this thread. Are we all illiterate?
    If Microsoft could think in the way of a user it would help a lot of people.
    So Rick Dee, please inform me how I misread the instructions?

  • How to make data flow from one application to other in BPEL.

    Hi All,
    I am designing work-flow of my application through BPEL(JDeveloper), I am making different BPEL projects for different functions, like sales manager got the order from sales person and sales manager either approve it or reject it, if he approve it it goes to Production manager and he ships the goods, now I want to keep sales person, sales manger,production manager in seperate BPEL files and want to get the output of sales person to sales manager and sales manager to production manager please help me in dong this.
    I was trying to make partner link in Sales manager of sales person and getting the input from there. I dont know this is right even or not, if it is right I dont know how to make data flow from one application to other.
    Experience people please guide.
    Sales Person -----> Sales Manager ----> Production Manager
    Thanks
    Yatan

    Yes you can do this.
    If you each integration point to be in different process, you have to create three BPEL process.
    1. Create a Async BPEL process 'A' which will be initiated when sales person creates the order.
    2. From BPEL process 'A' call a ASync BPEL process 'B' which has the approval flow. Depending on the input from process 'A' the sales manager will review the order in workflow and approve or reject and send the result back to process 'A'.
    3. Based on the result from workflow, invoke the Sync BPEL process 'C', where you can implement the shipping logic.

    Hi,
    As you have found in the View Menu of iChat is the option to Display the Recipients Bar
    This bar when clicked will display the Screen Names that you know for your Buddy and your own Screen Names.
    The Buddy's names are in the "To:-" section whilst your own are in the "From:-"
    Example pic from my iChat 6
    The Chat window has to Be Open.
    The Buddy's current name becomes a Drop Down that show the To and From names.
    It appears to allow you to Connect Google or Jabber IDs to AIM Buddies but the tick will move to any valid Account if you change either the To choice or the From choice.
    AS you say about the add Buddy drop down that appears - when your Buddy list are displayed as one an extra drop down appears fro you to Select the account/list it is joining as a Buddy

    how can make a room from my start up disk in in mac pro

    Only you can decide what you want to delete to free up space on your PB, Personally I think you'll find 17 GB won't go very far when you start to add video.
    Consider an external drive. Don't forget if you let your free space fall below 10% of the total size of the drive you will risk corrupting your directory structure or causing other damage which may result in a loss of data.

  • How to make "More Products" from Answers visible

    I am using OBIEE 10.3.4.2.
    I developed a solution that requires "Delivers". On my developers' box (Windows 7) everything is visible. Under "More Products", I see:
    Delivers
    BI Publisher
    Marketing
    Disconnected Analytics and
    Download Oracle BI for Microsoft Office.
    The moment I put my RPD and Catalog in System Test--which uses https:// and on a UNIX server, I can now only see:
    Download Oracle BI for Microsoft Office.
    which makes me suspect that their is a setting/configuration that is preventing me from seeing these products.
    Can someone tell me how to make these products visible? What settings do I need to change to make them visible?
    Thanks,
    "D"

    I shut the services both in SYS Test and my DEV box.
    Zipped the Catalog.
    Deleted all the old catalogs from my DEV box.
    unzipped the new Catalog
    started the services and I can see everything under " More Products"
    Shut down the services
    Moved back the Catalog to Sys Test
    And NO LUCK!!!
    I am beginning to think it is something to do with SSL

    Hi,there:
    How can i make a .exe from form builder which can run without form builder?

    Hi,
    You can try to create a batch-file. For instance on WinNT create a CMD file. On Win95/98 create a batch file.
    In that you can use (depending on where you've installed forms/ reports)
    D:\orant\binf50run32.exe <user>/<password>@<database> <startform>.fmx

  • How to make a call from a Web page

    How can I make a call from a number on a Web page ?
    If I select the number, I can only copy it ... then I cannot cut and paste into the phone dialing section ???
    I thought that by selecting the number on the Web page and holding it this would trigger the dialing ... like I used to do with my 9900 Bold BB.

    Are you holding the number or just pressing it quickly? Holding anything will produce a menu whose options would include cut & paste but just pressing the number should activate an action, in this case dialing the number.
    Try just pressing the number with a normal press and not holding it and post back with your results.  
    - If my response has helped you, please click "Options" beside my post and mark it as solved. Clicking the "thumbs up" icon near the bottom of my response would also be appreciated.
