Using IMAQ create - Suggestions needed

Hi ppl,

I use a lot of IMAQ create VI to create image stamps in my application. Since there are a lot of instances IMAQ create it will be better to create all the references of the image at once and use them. Or is it OK to create buffers to image and close them inside each sub VI. My fear is that since these sub VI is called inside the loop it will not be a good idea to open the reference of the image for each iteration.

Thank you

If you create a reference to an already created image and if you call IMAQ Dispose.VI on this reference so as the image will be deleted from memory. Thus, the image will also be not available in the other thread where the image was created first.

I think it is best to create the image at the start of the program if you need very often an image 'assistance' to store the results of treatment. I guess that it make little difference in a Subvi if you pass the reference of the image through the front panel or get with IMAQ create. The difference is in not throwing images every time.

IMAQ has all open one image at a time by using a Boolean value, you can close connect to the VI.

  • How to use IMAQ Bayer to RGB?

    Hello everyone.

    Could you please tell how to use IMAQ Bayer to RGB. I read the help that need us Bayer settings. But in aid have no structure of the Parameters of Bayer. I find any example of Bayer IMAQ to RGB and Parameters of Bayer in Labview

    Please read my poor English and help me!

  • How to use IMAQ detected Shapes.vi

    Hi all

    I learn NI Vision, I don't understand how to use IMAQ detected Shapes.vi to detect shapes, such as lines, ellipses, who can give me an example, thank you.

    Hello

    This function uses the edges of the object and try to adapt with different shapes such as rectangles, lines, or some cirles.

    First of all, you need to set parameters to extract the edges of your objects. You Brown the threshold (in order to find the correct edges of your object). You can then choose the parameters of the shape to fit. For example if you want to adjust with a circle, you set the min and max possible RADIUS.

    Try this with vision assistant, it will be easier. And try also with fine contrasting images.

  • IMAQ create and SubVIs

    Hello!

    I am video capture with IMAQ.

    I have a hand program and a Subvi, which made the acquisition.

    When I use the Create.vi IMAQ to allocate say 5000 photos in the Subvi runns all fine

    but whenever I call the Subvi there is a delay until all images are ready for the acquisition.

    So I tried to make the distribution of the hand-Programm-VI where is enough time to do this while the user makes other things.

    Then I put a reference or a single entry to the Subvi with table empty I allocated.

    When I run the program now acquiring works but is about 10 x slower than before.

    What's wrong? Why ventilation is in the Subvi to run at normal speed?

    Welcome C.Riedel

    Thanks to all who tried to help, but I found a solution (unsatisfactory).

    I completely Redid the Subvi by copying and pasting the code in parts to a new VI...

    and it works now. Jey!

    So Bruce was good, the concept is correct. Thanks for that!

    The source of probs remains unknown... NaH... but fortunately it works now!

  • Save to PNG using IMAQ file write file does not save good Gray Scale

    Hi - I have a simple VI which reads a raw U16 file and then try to save the option IMAQ write PNG file (because I want the 16-bit format).

    I defined a custom color table which is just opposite of gray, and this is applied to the image.

    The Image displays properly, but saves the PNG file with non-inverted grayscale.

    U16 RAW file is titled "Martha 1849-02-001-6 - view0000_raw_grey_16bit.raw' and sent to ftp://ftp.ni.com/incoming. "

    How is it and how do we get this working correctly?

    Thank you

    No! your custom color table to display the images, not apply to the image.

    In additional, it cannot save the palette as well as the 16-bit image. The pallet can be stored with 8-bit 'indexed' image.

    What you can do - if you need just reverse gray, use IMAQ opposite to calculate the negative value of an image.

  • DVD-R discs play only on internal burner/reader of DVD that was used to create the disc?

    Hello

    This is the DVD-R that I created will not play on my Player DVD TV Philips standard or any other DVD player other than the one used to create the floppy disks?  I tried to lower the record speed of Windows DVD Maker, Cyberlink Power Director, and Nero 11 and all have the same issue?  I can only read my disks on HP laptop DVD drive?  The discs I used are:

    Philips DVD - R 4.7 GB 1-16 X
    Memorex DVD - R 4.7 GB 16 X

    My old Windows XP machine has no problems burning these discs and they play back well on Player DVD TV Philips and all players with my friends.

    This problem is driving me crazy! This is a 1 year HP Pavilion dv9000 with built in DVD/Blue Ray recorder. It runs 64-bit Vista Home Premium computer. All Windows updates are made and there are zero viruses and malware.

    Any help would be appreciated!

    Read the info above about the correct format to burn in.

    Burn a disc using the ISO image format

    Choose the size of the ISO image when you need a highly compatible disc that will play in computers with an older version of Windows or in devices such as CD and DVD players that can play video files and music digital. For more information about choosing a disc format, see which CD or DVD format should I use?

    See you soon.

    Can we do with Muse or need something like Dreamweaver and custom coding?

    Hello

    Yes, you can create using Adobe Muse of these sites. You will need to scroll down anchor points. You can take a look at this article

  • Adobe Muse can be used to create the database of Web sites?

    Adobe Muse can be used to create database, Web sites or is it only, through 'replace the image through to travel away from your computer'.

    Hi Edgar,

    I'm afraid that this is not possible in Muse at this stage, I will recommend that put you that on our ideas here, section ideas for features in Adobe Museand inform our team of devs to this requirement.

    In muse, you can conceive only of static content. Dynamic content that you can return via DB, you need to write custom code and insert it into Muse via the option "object-> insert html ' or 'properties-> metadata-> html for the head.

  • IMAQ CREATE, image type setting

    Hello

    I'll put my f031b Pro Guppy camera pixel format.

    It seems too long I put attributes with property nodes: pixelformat as Mono 16, no matter what I put in the "IMAQ create"--->"image type", I still get output 16-bit gray scale.

    Is this correct?  What can control when I change the image type to "IMAQ Create"?

    best,

    Wen

    If the image is passed directly to the Image to get VI of IMAQdx, the type is unimportant since it is converted by the driver when it fills with data. Only the border size is relevant.

  • Using to create tooltips for status bar icons

    Does anyone know if there is an easy way, maybe a library I can use to create tool tips that I can use to bring up the information next to my system tray icon?  Or is it something that I have to dive into the SDK to do?  Thanks in advance!

    Hey tstanley-

    CVI does not provide an API to create one of these balloon popups.  However, many other tasks to icon tray can be accomplished with functions in the Toolbox of the programmers.  It is an excellent example that illustrates these functions named Trayicon.

    To create the balloon popup you speak, you're either going to have to manage the API icon by yourself, or make some changes to the toolbox.c source code, because some necessary Manager functions are not exported.  Use this as a reference, I added a few lines of code to toolbox.c (without any verification for clarity of errors) to display a very simple balloon popup.  Let me know if you have any questions.
