Keep all overlay information during image acquisition when using the base IMAQ package

I have made an X control from the IMAQ image display control that has the ability to overlay points and lines on an image but when I put my X control into my image acquisition loop the overlay information disappears  with every new image I acquire.
How can I keep the overlay in place and just update the control with the new image and not overwrite the overlay data? I have tried the merge overlay function but this does not seem to work.
Thanks.
Solved!
Go to Solution.

Overlays normally are erased when you acquire a new image.  You could create the overlays on a separate image, then copy the overlays to each new image before you display it.  The other option is to recreate the overlays for each new image.

  • Why does the revealed image flicker when using the Show/Hide feature?

    I started using the Show/Hide Button and Forms function in InDesign CS6 and have had some peculiar things happen. I was mocking up some samples and on the swf version if you hover over the left side of the blue rectangle all is fine but if you move to the right side of the blue rectangle the image starts to flicker. When you hover over the red rectangle the pop-up image just flickers constantly. I guess there must be some issue with having the button for a revealed image under some portion of the revealed image. See: http://www.idugsf.com/_a/FI_BookSamples.html .
    The problem went away when the button and the revealed image did not overlap.
    This problem didn't occur with another file I had originally created in CS5.
    On the pdf version the buttons which are on their own layer behind the revealed image moved to the front in the pdf: http://www.idugsf.com/_a/FI_BookSamples.pdf

  • Image rotates when using the crop tool

    New to Aperture  my question is when I use the crop tool the image appears to rotate in one direction or the other.  Then of course in limited to the size i can drag out the crop window by the edges of the photo itself.  Any ideas

    If you use the straighten tool first and then select the crop tool, Aperture will show the entire image including the parts that were cropped off during the straighten operation. Other than that, can't think of what you are seeing.

  • Entire image moves when using the Healing Brush

    After I alt/click to select the color for the brush, the entire image moves with the mouse.  Any ideas on this?

  • The configuration file did not contain well formed AppV configuration XML - When using Office 2013 ODT package

    All,
    I'm experiencing an issue where when using the Office 2013 package pulled down from ODT, that if I try to change the locations of either InfoPath Filler 2013 or Publisher 2013 from the default of Microsoft Office 2013 then I receive the message "The
    configuration file did not contain well formed AppV configuration XML. Please check the management server event log for more information". If I check Applications and Services\Microsoft\AppV\Server-Management\Admin the error displayed there is "An
    error was encountered parsing dynamic configuration file '0'. However I am able to change the shortcut location for all other applications except the above 2. I've tried redownloading the files using the ODT and also changing the version number (so far I've
    tried both the 15.0.4631.1002 and 15.0.4659.1001 with the same result).
    As all I'm interested in so far is having a package which contains Visio and Project I've tried following the article to exclude all the other Office elements:
    http://technet.microsoft.com/library/jj219426(v=office.15).aspx#BKMK_ExcludeAppElement. However the package looks to be the same and when I load it into the management console all the options and elements to Office 2013 are available like they were before
    when I hadn't set the exclude tags so I'm not sure whether the ExcludeApp parameters actually work correctly.
    This then brings me onto the 3rd issue I've experienced. I have a group for the Visio users and I've set custom security for them to have Visio delivered to them but not Project and then a seperate group for just Project users who will have Project delivered
    to them but not have Visio. When testing this sometimes seems to work but other times it seems to trip out and a user just in the Project or Visio group will get all of the Office 2013 applications and under the default location of Microsoft Office 2013. When
    trying to spot correlation with this it appears random and can happen to any user on any device. We have sequenced a few applications ourselves where different parts are needed for different users and we have successfully managed this using different security
    groups for different applications, just as I'm trying here with Office 2013.
    Has anyone else experienced the issue with the "did not contain well formed XML" as at the start of the post and how were you able to resolve this? Also has anyone any advice on how to troubleshoot the issue with the security seeming to trip out
    and publish all applications within a package to a user regardless of whether they are in the correct group or not?
    The management / publishing servers are 5.0.1224.0 which is SP1 HF4 and the clients are on SP2 HF5.
    Thanks

    Nicke,
    The config files are UTF-8. I did find the same article as yourself, however when searching for the value ‘TakeoverExtensionPointsFrom46=’ within either of the configuration.xml files that text isn’t found.
    No sinister reason not to share the file used, just it’s the same structure as referenced in the article:
    http://technet.microsoft.com/en-us/library/dn745895(v=office.15).aspx. The only difference being that I’m using ProPlusVolume and I’ve set a version number (which is the October
    2014 update). I’ve even looked to follow the above example as closely as possible in just using the ExcludeApp ID of Access and InfoPath, just to try and prove the process. However I still get the usual full package. The version of the Click-to-Run setup.exe
    I’m using is 15.0.4623.1001, so later than the version specified at the end of that article which is 15.0.4619.1000. Where can I expect to see the elements excluded? Will it be when loading the package into the management console or would it just not appear
    on the machine when delivered?
    <Configuration>
      <Add SourcePath="C:\OfficeDeploymentToolV2" Version="15.0.4659.1001" OfficeClientEdition="32">
        <Product ID="ProPlusVolume">
          <Language ID="en-us" />
    <ExcludeApp ID="Access" />
    <ExcludeApp ID="InfoPath" />
        </Product>
      </Add>
    </Configuration>
    3). We’ve not used global publishing in our environment yet so I will try that. I’ve set both GlobalRefreshEnabled and GlobalRefreshOnLogon to True and when using the command Get-AppvPublishingServer on the client I’m testing with I can see this is pulled
    through correctly. I’ve also added the client name to the AD group used to grant access to the package and it is published. However nothing is pulling through onto the Client, so are there any steps I’ve missed or misinterpreted when looking to set this up?
    I guess the global publishing is there to keep in with licensing for Office being per device? On a slight aside, as Windows licensing is being changed to allow per user licensing
    http://www.zdnet.com/microsoft-to-make-per-user-windows-licensing-available-to-enterprise-customers-7000035401/ does anyone know if there are any plans to allow for Office / Project / Visio licenses to go per user as well? We’re a volume license customer
    rather than subscription based so I think a lot of the options to selectively deploy Visio and Project are excluded for us.
    Dan,
    Ok that explains why the security could be tripping out then and leading to this result. As above I’ll try with global publishing and see how I get on.
     From what I’ve read / watched  I think only one Office 2013 package can be published to a machine, so we would be unable to have a separate package for Visio and a separate package for Project and then attempt to deliver
    them both together. If a user wanted both Project and Visio then I guess we’d need to have a combined Project and Visio package to cover than scenario, but then 2 more separate Project and Visio packages for those who would only want either Project and Visio
    (I think).
    The scenario we’re looking at is to see whether we are able to deliver Project and / or Visio to different users through an AppV package and this will then cover users on XenApp or on fat clients. Only a small proportion of our
    users will need access to Project and / or Visio so therefore we’d only have a small amount of Project and Visio licenses.
    However from what I’ve tested up to this point and from what I’ve picked up from Forum posts / watched on TechEd sessions is that as publishing is Global and is unable to use different security groups for different elements of the
    suite, then using Office through AppV is only suitable if you will be delivering the whole suite (including Project and Visio) to all of your users. So in a scenario where you’d only want certain elements to be delivered to a handful of users then you’d need
    to keep with traditional ESD methods to have this installed onto fat clients and steer clear of XenApp. If wanting to install to XenApp then a lockdown tool like AppSense or AppLocker would also need to be brought into the equation.
    Is my understanding above correct or have I missed some options / methods?
    If the full Office package is always delivered but a company only has Office licenses and no Project and Visio licenses for all its users, how do they stop Project and Visio being delivered and being available? Or again if you have
    this use case is the AppV method one which will be unsuitable?
    Thanks

  • I have changed operator and also changed IOS and did a back up of my old phone in Itunes so i would keep all my contacts etc. Now when i want to get everything back in the phone, Itunes asks me for a password, which i do not have. How to bypass this?

    I have changed operator and also changed IOS and did a back up of my old phone in Itunes so i would keep all my contacts etc. Now when i want to get everything back in the phone, Itunes asks me for a password, which i do not have since i did not enter any password when i did the back up. Is there any way I can bypass this password request? Otherwise i have lost all my contacts etc.
    Greatful for help.

    Contacts are designed to be synced to a supported application on the computer or a cloud service like Gmail, iCloud, or an Exchange server.
    Have you failed to use the device as designed?

    This was EXACTLY what I needed about the purchases I made from my device. However, is there a way to re-download other ones you've made from a computer? Because I realized some of them were not just purchased from my device.
    This is a picture of what it looks like now:

    As you can see, the stuff circled in red doesn't give me an option to download from Cloud Beta because it already says "downloaded".
    any way to get around that?

    It's too late for that. Maybe you should consider setting up your next iPhone to backup to iCloud... it happens automatically without user intervention once it's set up. All that's required is a power source for the phone and a WiFi internet connection.

  • How to add image in virtual dir / i/ 11g when using the embedded gateway

    Hi,
    Does somebody knows how to 'simple' import a file or directory
    into the /images/ or /i/ directory created by APEX without tricks like in How I added a  new image to APEX in 11g when using the embedded gateway.
    when using Database 11g with the embedded gateway. with webdav of ftp.
    When I use the url http://localhost/images
    I need to logon.
    There is not 1 username/password that I can use. I tried all.
    When I try http://localhost/i/16admin.gif then the gif is shown.
    I must be something with ACL's or DBMS_EPG or maybe the default port 80 that I use?

    Hi Jules,
    You need a user with XDBADMIN rights to access the WebDav. Once you have access, you can open the URL as webfolder (in IE).

  • Bug Report: Images broke when using get_blob_file_src and not authenticated

    Hi,
    it looks like that images which are retrieved with a
    apex_util.get_blob_file
    call are broken when the user is not authenticated. If the generated image URL is directly called in the browser, it shows a 404 Not found error with a "Invalid Session" in the error log file on the Apache.
    The above image URL is generated when using the apex_util.get_blob_file_src function call. If the new IMAGE format mask (eg. in an IRR) is used it seems to be fine, because that generates a apex_util.get_blob call.
    Testcase:
    1) http://apex.oracle.com/pls/otn/f?p=17201:3 (That's the sample application with page set to "doesn't need authentication")
    -> Image column is broken
    2) Login with demo/patricks_demo_workspace
    3) Go again to page 3 (Products)
    -> Image column is displayed correctly
    Thanks for looking into that

    Hi Scott,
    when I woke up today it also came into my mind that it may has something to do with the referenced P6_PRODUCT_IMAGE in the
    apex_util.get_blob_file_src('P6_PRODUCT_IMAGE',p.product_id)call which references a page item on a non-public page.
    I think apex_util.get_blob_file_src or better apex_util.get_blob_file shouldn't really care if the "definition" of how the BLOB looks like and where to read the information from is on a non-public page. Because it doesn't read or set actual data it just reads the definition, so it shouldn't be a security issue.
    Another question is, if it's so useful to reference a page item to get this BLOB information and not directly being able to specify this information as parameters in the apex_util.get_blob_file_src call. I think I also raised that during the 3.1 beta, because in case if you just want to display a BLOB you still have to create somewhere a page item of type "file browser" to being able to reference it in the get_blob_file_src call. Direct passing of the vales would also be more transparent and self documenting.
    BTW, the above code is an example of the "Sample Application" and wasn't made up by me, so probably a lot of people are using this technique to get rid of there own blob download procedures.
    Have a nice weekend

    I have been noticing that when using the computer the mouse keeps going in places where I really do not want and just now select the sentence without I have done anything. Sometimes goes to places like bookmark or open tabs in website when I am reading a page.
    Also I have noticed opened windows that I have not opened.
    I have verified the sharing folder and also the remote access but it not let me turn it off.
    Also I have add a password to my computer and even using the same one it looks like is not working.
    The I photo stopped working, Mac Mail does not let me add rules (this is from one day to the other)
    The computer is mine, the internet I use is payed by me with a password. I did not give permission to anyone to use my computer or share my files.
    In system preferences in the sharing folder is showing everyone and staff.
    My computer is private I do not own a company and I do not have a network set up in my house.
    I had my photos removed from my computer and even after trying to reinstall I photo and fix the Mac Mail is not working.
    I am receiving emails saying that I have sent emails to people that I do not know and including in a time where I am working and not using the computer.
    Any suggestions in how to fix this issue?
    I really appreciate.

    With the multitude of issues you have I would take it to an Apple store or AASP and have them sort it out. Then I would sign up for Apple camp or one on one.

    Nobody can tell you anything without proper system info or other technical details. The standard answer with all text issues simply is, that you have a "bad font" on your system and need to get rid of it.
