Unexpected IMAQ image type conversion indicated

When wiring an Image to an IMAQ "object"/vi (e.g. Write Custom Data, Image Info, Calibration, ...) a type conversion indicator (grey dot) appears whenever the wire starts at a property node.
The conversion indicator doesn't appear when wiring from a local variable or an unbundle "object".
I would expect the value of an image object to behave similarly, regardless whether it is wired from a local variable, unbundle node or property node. Am I getting something wrong, is this a bug, or is there really some data type conversion going on?
Many thanks for all answers
Patrick

The image type is a type def.  It appears that the Value returns a non-typedef value.  LV shows a conversion dot whenever you change between a non-typedef and typedef variable, even if they are the exact same structure.

  • Image type conversion

    Hi, How can i use BufferedImage class to perform image type conversion, thanks

    I fyou're talking about changing the image encoding, see the documentation for ImageIO.
    {color:#0000ff}http://java.sun.com/javase/6/docs/api/javax/imageio/ImageIO.html{color}
    Particularly the read and write methods.
    If you're talking about changing the BufferedImage.TYPE_xxx, construct a new BI with the same size and drawImage the previous image on it.
    If something else, clarify. And next time you ask a question, please try to be clear about your requirements.

  • Error -1074396077 (IMAQ Vision: Incompatible image type) after running IMAQ Mask

    I am attempting to process color picture of pellet. I want to exclude any particle that touches the edges of the color images. I created mask from original image and used this mask on the original color image to retain only the color particles that don't touch the boundary. The error occured  when I ran the IMAQ Mask. The error message is “Error -1074396077 (IMAQ Vision:  Incompatible image type)”. How can I fix it ?

    Hi XuanThuy,
    The IMAQ Cast function is part of the Vision Development Module (VDM), under the Image Management Palette, as indicated by this document: http://zone.ni.com/reference/en-XX/help/370281P-01/imaqvision/imaq_cast_image/. If you can't locate it and you indeed have the VDM, there may be an issue with the installation of this module. A similar issue has been encountered and resolved in this forum post: http://forums.ni.com/t5/Machine-Vision/can-t-find-IMAQ-cast-image-vi/td-p/340157.

  • LabWindows/CVI and IMAQ - Invalid Image Type when saving bitmap

    I create and image, grab it, then display it, but when I go to save it using imaqWriteBMPFile, I get an error that maps to Invalid Image Type, so I use imaqCast to cast it to an IMAQ_IMAGE_U8 type (which is what the orignal image was created as), then it works, except that my image has changed, that looks like the contrast or something has changed. Any suggestions?

    What kind of camera & IMAQ board are you using? I have seen similar problems when a 12 bit camera is used. The image is acquired as a 16 bit image, and if you just convert it to an 8 bit image, it ends up looking like the one you attached. To correctly convert to 8 bits, you need to shift the appropriate number of bits during the conversion. For a 12 bit camera, that would be 4 bits.

  • Automator - Change Image Type - Multiple page PDF- TIFF conversion

    I was able to do this on a friend's computer (not sure which version of OS X they were running), but this seems impossible on Snow Leopard.
    I need to convert hundreds of multiple page PDFs to TIFFs. I can't get this to work, and the Change Image Type option only lists single page PDF conversion. I could separate PDFs into multiple files, convert to TIFFs, but then I don't know how to recombine a bunch of TIFF pages into a larger file. From google searches, I know this is possible using tiffutil, but I don't really understand how to use that well, and I really need an automatic process.
    I'm at my wits end with this, because I did it just last week on someone else's computer and it was easy as pie. Why can't you convert multiple page PDFs in Snow Leopard?
    Any ideas?
    Thanks!

    I just tried this - two problems.
    It creates a separate tiff document for each page of the input pdf.
    Also, this action is just annoying because it results in randomly named files in some temp folder that i can only locate using the reveal finder item action. I know I can rename files in automator, but I'd really like to have the output file have the same name as the input file.
    It confuses me why they would remove this functionality in Snow Leopard.

  • IMAQ resample invalid image type

    Hi,
    I am rewriting an old non-versatile version of a VI. I don't have much experience but I have the old VI as sort of a template for what I need to do. It's weird but although I try to do things exactly the same way, they don't work.
    I acquire a high resolution image from the camera (IMAQ Acquire) which is too big (1280x1024). I want to resample (IMAQ Resample) it to 256x320px.
    I get the error message: Error -1074396080 occurred at IMAQ Resample Invalid image type.
    The probe I put in to read the Image Src shows the image correctly and tells me it is an unsigned 16 bit image. This should be a valid image type, right?

    No, not right. IMAQ Resample doesn't support U16 type (at least up to VDM2011). Refer to Help.
    Convert your image to I16 (if possible) prior to resampling.

  • Imaq invalid image type

    Hi,
    i try to analyse a video image. it is an image typ 32 bit rgb. In the sub vi I try to count the pixel with a red value greater than the green and the blue value. Therefore i need to split the colorplanes.
    After that I write the values in an arry to count them.
    Sometimes the Error "Invalid image typ" appears. I´m not sure why this error sometimes appeared and sometimes not.
    I hope someone can help me to find the solution.

    Hello,
    does the error happen only, when your ROI is passed as an empty cluster? So, if you have an active ROI, there is no error right?
    Make sure your ROI is not empty, or alternatively you could use "IMAQ SetImageSize" after allocating the memory for the mask (set the size to the same size as the input rgb image with "IMAQ GetImageSize".
    Does this help?

  • IMAQ image out- what's the best way?

    Hello forum,
    I'm developing an interface to acquire a square image from an NI-DAQmx PCI 6221 on LabVIEW 7.0 and Windows XP. At present I am simply collecting my information from a physical sine wave generator on the bench, but eventually this will be used to process images from a CARS microscope.
    My problem is that I am trying to figure out a user-friendly way of "buffering" all previously acquired images in the session, and then choosing one several of them to save as an uncompressed BMP. At the moment I am using two image displays; one for the whole image overview (picture indicator) and one to pan around and zoom on fine details (IMAQ image indicator). The IMAQ image indicator is also outputting to an IMAQ browser window, which I have modified based on the Browser Example.vi which ships with LV. However, there are several difficulties with this method.
    Firstly, I'm not sure how to select an indexed image from the browser itself to save; the only way I can think of would end up wiring the IMAQ image out to the BMP writing VI, but that would only save the current image, and not necessarily the one the user wants.
    Secondly, I haven't quite got the hang of combining case structures, event structures and while loops yet, so there's a very specific order things have to be done in or the program hangs, (e.g.. you must press the buttons: Acquisition - Unlock Browser - Stop in that order, nothing else works properly), and I'm pretty sure I've set the browser up wrong because every time I finish with the acquisition window, an error message appears.
    Thirdly, it would be nice if I could hide the browser window until I've finished with the other window, but I can't seem to get IMAQ windshow to do that. I have boolean constants wired to Hide/Show and Set/Get but no matter what combination of false and true I use, the window appears anyway.
    I will attach the VI and subVIs to this post in a zipped folder, and would appreciate any help you could give me. General constructive criticism on my wiring, methods, Rude Goldbergs, etc, would also be appreciated if anyone has the time, as I'm still pretty new to LabVIEW.
    Thanks in advance!

    Image Acquisition VI 0.4.zip ‏187 KB

    DH is right about the difficulty in removing wind noise, but hoping it might prove useful, here is a hint I copied from a thread somewhere in this discussion list.
    How to export audio from Final Cut Express to (free) Audacity and back again after noise removal.
    1) download Audacity
    2) in fce timeline, place in and out points at beginning and end of audio
    3) select that audio clip, and that clip only
    4)file-export-using quicktime conversion, in the pop-up box format as aiff, 44.1kwh 16bit stereo
    5)open audacity, make sure box in bottom left corner says 44100
    6)file-import-audio
    7)go to file and select it, click choose
    8) select part of audio with just wind noise, then go to effects noise removal, click get noise profile etc.
    9)when satisfied, click file-export, click ok, close audacity
    10)Open fce, drag your audio clip to the right hand end of clip. Move playhead to the in marking. Go to File-import
    select your audio file, choose.
    11) file appears in fce browser. Drag from there to overwrite and the audio goes into the track, perfectly synced
    My apologies to whoever posted this hint, I tried to find the name to give credit. This really does work to get rid of room hum, but wind noise is a really different beast and this may not help. I suspect, as DH says, it will remove too much of the audio you want to keep. Hugh

  • Is there a way to list the 'names' of the IMAQ images in memory?

    looking for a way to generate an array of strings that contains the 'names' of all the IMAQ images in memory. I'm doing some heavy image processing and the nature of the image processing functions makes it easier to work with multiple copies of images to avoid nasty surprises (like images declared one type being unexpectedly recast as another). Unfortunately, this means drawing dozens of wires everywhere to image disposal points, which does nothing but add clutter to the block diagram.
    I'd like to be able to poll the images in memory and delete only those images which are no longer needed.
    Thanks,

    Root,
    You could use IMAQ GetImageInfo to get the name of an image.  If your image references are stored in an array it would be easy to generate a list of image names using IMAQ GetImageInfo in a For Loop.
    Hope this helps,

  • Why does moving the mouse over an IMAQ image display slow the GUI down so much?

    I have a large application with several vi's running simultaneously under labview 8.6.1.  When I mouse over an image display control in one of the vi's, everything slows down a shocking amount in all the other vi's.  The windows task manager does not show a large increase in CPU use.  My pc is has a quad cpu with 4GB of RAM, and the CPU and memory loads do not appear to be terribly taxing to the system.  However, many of my vi's apparently come almost to a standstill if I just move the mouse in a circle around my image control.
    This looks like it is largely a GUI display issue.  If I make a new vi and put a while loop in it that only displays the iteration loop number to an indicator, I can see the iterating occurring, then stopping totally when I mouse inside the image display control.  When I stop moving the mouse inside the control, or when I move it outside the control, the interation loop number jumps up, as if it had been incrementing behind the scenes the whole time.  So only display of the interating was halted.
    This problem occurs even if the vi with the image control is not executing.  If the vi with the image control is open but not running, and I mouse over the image on it, the other guis all come to a screeching halt.
    Does mousing in the image display control really utterly crush all other guis in all other labview windows?  Is this an issue inherent to the image display control?  If so, is there anything I can do about this? 
    Also, this issue is not entirely limited to display.  I started looking at it in greater detail because this issue also exposed what I think is a race condition in my code.  I have a vi that acquires an image from a ccd and puts it into an IMAQ image.ctl.  This image then gets passed up to a vi up the call chain, and is put on a queue and sent over to be de-queued by a vi that has the image display control.  Here's the kicker:  when I mouse over the image display control, the image successfully gets acquired inside the subvi, and if I probe the wire leading to the output IMAQ image display.ctl, I see the image.  If I simultaneously probe the wire coming out of the subvi one level up the call chain, the image gets lost about half the time.  This only happens if I am mousing in the image display control IN A TOTALLY DIFFERENT AND SEPARATE VI.  If I bump up the priority of the ccd image acquisition vi to 'highest priority', the problem only happens about 1% of the time, and I really have to mouse around to make it happen.  Still, it's disturbing that mousing in the GUI in one window results in a failure of a separate subvi to simply pass an image up the call chain.  I understand that IMAQ images are referenced rather than passed by value, but I don't see why there should be a failure to pass the image up the call chain.  I've looked for a race condition, but can't find one.
    Eric

    I have finally been able to replicate the behavior that you are seeing on another computer once the image was large enough.  Here are a few notes about this behavior:
    First. The UI only slows down when the images are large, 16 bit images.  The reason why this is unique to 16 bit images is that they can only be displayed on the front panel as 8 bit images.  The workaround that Weiyuan suggested to change the 16 bit display mapping hints towards the root of the problem...that any time a mouse runs over the indicator, Windows asks the entire image to re-draw (having a separate indicator overlapping the image will create the same behavior).  With a 16 bit image, not only does the image have to re-draw on the screen but the 16 bit pixels need to be mapped to 8 bits.  When setting the 16 bit display mapping to Full Dynamic, this requires mor computation/pixel than 90% dynamic or one of the other mapping schemes.
    This is expected behavior if your program is running and you're trying to display a large 16 bit image.  To fix this behavior there are a couple options:
    Change the 16 bit display mapping to something other than full dynamic.  You can choose which 8 bits to display or if you want to map the bits. 
    Resize the image just for viewing purposes on your front panel (since you aren't going to view every single pixel of you image on the screen). You can use the IMAQ Resample.vi to do this.  This will allow you to take your 1500x1500 pixel image and only display a 500x500 pixel version.
    If you are interested in viewing small details of the large image, consider just displaying a smaller region of interest at a time.
    Let me know if any of these solutions work for you.  Good luck on your application.

  • How do I find the image type of an image file

    This was posted on the LabView forum in error yesterday,  Please excuse the dual post.
    I am trying to open a JPEG image.  If I do not know the image type (8U, 16I, GrayscaleSingle, ... etc)... is there a way to find out that information?
    If you open the file using IMAQ ReadFile...you have to supply a Create Image input to allocate space...the input specifies a type to read...but if the type of the stored data is not the type specified in the read file you either read the file as the type specified, or the file does not produce any values...(and no error is produced).
    Examples:
    Store a JPEG as a Single Percision Floating point image.
    Use a Creat File to specify that the file is read with the following types...with the following results
    Type Specified        Type Read         Resulting image
    U8                               U8                     8 bit image appears
    16I                               16I
    Solved!
    Go to Solution.

    Hummer1,
    There are two methods to accomplish this:
    1) IMAQ GetFileInfo, which has quite a few outputs involving the image details.
    2) Read JPEG File, which you can unbundle the image data output to get the image depth, or other attributes.
    I would reccomend the IMAQ function, due to it being more detailed.
    Hope this helps

  • Handling IMAQ Images in the TestStand Opeator Interface

    I'm modifying the LabVIEW Operator Interface to display images from IMAQ VIs on the front panel. I've got it to work a number of ways, but never if I compile the interface into an executable.
    I've tried using the "IMAQ Image Cluter to Image Dataype" and "IMAQ Image Datatype to Image Cluster" vi's to store and pass references to the Operator Inteface. It works in development mode but not when built. I understand this won't work as the reference is local to the adapter you are using so I abandoned that.
    I've tried storing the Image into a global VI and then reading that global VI in the interface for display. I've made sure to call the Global VI dynamically in the operator interface so I'm using the same VI and not one compiled into the executable. It works in development mode but not compiled. Don't know why.
    Another method I tried was to use the "Flatten To String" and "Unflatten From String" functions to store the image in a local string (as a binary string) in the sequence. I then tried accessing the local with the "ProperyObject" Method "GetValString" in the Operator Interface VI. When I try this I get an error and the development system shuts down. I know I'm access the local correctly as I have accessed other locals from the sequence in this manner.
    Any ideas why one or both of the last two methods are not working for me? Is there any other methods that would work? How about sending the image to a common dll? Can you store an image or image reference in a dll so any platform could access it?
    Thanks,
    Dave

    Thanks for the tip about trying another data type. I tried an numeric array and it did not work as well. But now I could see what is happening. When the GetValString reads the local it does not interpret the escape code '\'. i.e. if the string contains '\00' it ends up as '5C 30 30'. The Unflatten From String vi is expecting hex 00 and an error occures.
    I wrote a crude VI to look for the escape code and convert what follows to pure hex. It first converts the string to byte array, interprets each byte, creates a new hex array then converts it back to a string. The good news is that it works for numeric arrays, and I was able to read the array values in the Operator Interface by reading the flattened data from the sequence. However, when I applied the VI to the Image Flattened data, the array was 2,295,879 elements long and my VI was way too slow to convert the whote image.
    Is there a fast way of converting the string to pure hex values?
    Don't know why my VI didn't show up. I'm now trying to attach an image of the block diagram.

    No. Grab generates tiff files. The Grab help suggests using Preview to open and convert the file types.
    There are a number of other image conversion tools out there as well.
    You might also try CMD-SHIFT-4 - this permits you to select a portion of your screen and saves it a .png file. Most modern servers understand png.

    Since Y is maintained in header say X.Also Y has its own BOM with active status 1.
    I took  MRP run for header X, I found that Y has generated planned order without conversion indicator. 
    Is there any setting missing.
    Kindly suggest.

  • LabView 8.6 Imaq Image.ctl error when trying to probe wire.

    I just installed 8.6 from 8.0. Now when I try and probe a wire I get a dialog that wants me to find the IMAQ Image.ctl file. If I cancel out of the window about three time it will finally set the probe. I do not have vision or IMAQ on this computer. Has any one had this problem? Is this another one of the times I get to uninstall and reinstall LabVIEW?

    Does this happen for all of your wires that you try probing, or just one particular data type?
    It does happen for all of the wires types.  
    Does the dialog look similar to the dialog that appears when you load a vi that can find the associated files, or does it appear as something different?
    If I right click I get a dialog that looks very similar to the dialog that pops up when the associated files are missing.
    I might reccomend installing vision acquisition software (only install the IMAQ driver, not IMAQ-dx) and see if this fixes the problem
    Is this avaliable if I do not have a license for vision 8.6?
