• IMAQ Vision: image not valid type

  I use the evaluation version of LabView Pro and Vision Builder to process a video taken from a Webcam from Microsoft. I try to apply a part of the function as a filter of treatment or look at a histogram as graph below but LabView always returns invalid image type.  I assume that these functions cannot process the image directly from webcam (using Vision acquisition) and may need to be converted before their transformation. However, I'm unable to do it. Please give me any suggestions or provide that I have to use the function

  

  In most cases, WebCam will deliver Image RGB (color). Even if you have turned on the WebCam in grayscale mode (then RGB components are equal). IMAQ polygon can handle the U16 only U8 I have 16 or types of SGL.

  What you can do:

  (A) use IMAQ ColorHistograph instead of the polygon IMAQ.

  or

  (B) convert your color to grayscale image (good way is to take ExtractSingleColorPlane IMAQ and set the type of intensity. Destination image must have type Grayscale U8). You will then be able to use IMAQ polygon.

• IMAQ resample invalid image type

  Hello

  I'm rewriting an old non-versatile version of a VI. I don't have much experience but I have the old VI as a kind of model for what I do. It's weird, but even if I try to do things exactly the same way, they do not work.

  I acquire an image high resolution camera (IMAQ to acquire) which is too large (1280 x 1024). I want to resample (IMAQ resample) at 256x320px.

  I get the error message: error-1074396080 occurred in the type of IMAQ image resample not valid.

  The probe I put to read of the Src of the Image shows the image correctly and tells me that it is a 16-bit unsigned image. This should be a valid image type, right?

  No, not right. IMAQ resample does not support the type of U16 (at least until VDM2011). See help.

  Convert your image to I16 (if possible) before resampling.

  Hello

  I found the "imaq create King vi" and its good for what I want to do, but I have a problem.

  In Control Panel, you can set only one KING. But I want to create many Kings (lines) on the same image of King cunstructor to make me a table of coordinates "line".

  Can you help me?

  Thank you.

• How to determine the image type in IMAQdx

  You can use the property IMAQ node to determine the image type when creating images.  However, when I try with IMAQdx I get 0 bits per pixel and I do not see a type as for IMAQ image.  I am creating 8-bit images when my camera is color.  How can I determine the image type of the camera file?

  

  Hi rammer,.

  IMAQdx exposes an attribute called "TypeOfImageInUse" that will give you the image type expected for the current settings of the camera. However, none of the functions that return an image IMAQdx will automatically convert the image to the format automatically, so you don't normally have to worry about this.

  I do not believe that the attribute is now directly exposed as his own property node, but you can use the CameraAttributes-> ActiveAttribute/ValueU32 those for questioning as any other attribute of dynamic camera.

• create the type of step for a stage of COM

  Hello

  I use the COM adapter to interface with TestComplete.

  My current setup is that I have a Master file of sequence that contains two sequence files (one for each trial).

  The individual called movie file have 4 steps as indicated:

  Get property: Create the new object

  Calling a method to open project

  Call the method to run the test, and then pass the parameter in TestComplete

  Get the result of the property

  My problem is that if I want to spend a different setting in the step to call the method to run the test , I have to create another sequence file to do this.

  Is there a way to create one Type of step to call the method, run the test and pass parameter to TestComplete?  and how will this affect the other steps in this sequence file (for example to create new object, open a project, Get property resut)?

  Thank you!

  Jigg,

  Yes, I think it worked!  Thank you very much!

  Question: to chaange the param1, it is necessary to specify the module and change the value in the edit sequence window call under the table of parameters.

  Is it possible to build an easier user interface as the synchronization-> Wait-> Configuration window not to wait, where you can just put in the value of the parameter, and that's all.

  Thank you

• IMAQ flatten image for the 64-bit version of string

  Hello

  I noticed customer odd based on vision "flatten image chain" on labview 64-bit edition. In my program I use flatten image to the string (with compression to JPEG and kind of flatten Image) to compress and send data to another application. I noticed on the compressed image color missmatch. I say red (255,0,0) 32-bit RGB image and I flattened for string and then save this string as a binary JPEG using Write to vi. When I open the file of the picture is blue (0,0,255). It doesen't matter how data is written (big endian, little endian or native) the result is always the same. 32-bit edition Labview, the code worked correctly.

  I reported a bug in the NC and I'm still waiting for a solution to this problem.

  LabVIEW: labview professional development system 2010 32/64 bits (with vision development module) completely v10.0f2 lie

  Systems: labview 64 bit on windows 7 64 bit-> flatten image to string-> false color

  LabVIEW 32-bit on windows 7 64 bit-> flatten image to String-> colors OK

  LabVIEW 32-bit on windows 7 32 bit-> flatten image to String-> colors OK

  A picture of the block diagram that I used to test the conversion is attached.

  See you soon

  Hi 3DVision.

  I think I see the problem... you code looks like he expects that out of "flattening the image of the chain" will actually be a JPG file as a string, because you have chosen to use the JPG compression options. However, this is not the way that VI is intended to be used. It is simply a way to convert an image type of Vision in a string representation which can be easier to haul around (for example via the network, the user file format, etc.). It is a parallel to normal 'flatten' that can be used on any type of data from LabVIEW. The format of this string is the owner and has provisions for storing information that is specific to the Vision images that cannot be represented in the file formats normal image (overlay information, benchmarking, custom, etc. data info). If you are save the string flattened in a file and expects to open as a normal JPG file, it is unlikely to work properly. The only way that it would be guaranteed to work is if you switch to the corresponding VI "unflatten chain. I don't know why it works in 32-bit mode, but it sounds like a lucky fluke.

  For your use case, you probably want to use the VI "IMAQ write the string. This does not give a result string that is identical to the specified file format.

• 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.

• Hunt group type Set up with outdoor extension numbers IE cell phones

  With the help of CUCM 9.1

  Is there a quick and easy way to create a type of fighter group set up to help on the outside (cell phone numbers)?

  The scenario will be a (person who will be on call) using an internal DID to be forwarded to a cell phone of the person oncall this particular week.  If no response she pass 4 members to the next line and also try their cell phone.  After that it would just repeat the whole process.  So far, it looks like a solution is possible with the single line scope perhaps?

  Any ideas would be grealy appreciated.

  Hello

  I put something like this on CUCM 8.0 a couple of years.

  I used the Mobile connection feature as you suggested and it worked ok after some playing with timers.

  The main problem was that it was impossible for remote users to disconnect to the hunt group. They could disable Mobile Connect using the IVR, but calls would still ring on their deskphones - if you log on phones (i.e. Extension mobility) before leaving the office this problem should appear.

  The other question was how long calls to connect especially if a couple of people in the Group has not responded. In fact, we recorded a message asking callers to be patient, which was played when the call was received first (we were using UCCX to IVR and call transfer).

  I hope this is of use.

• First Pro CC gives an error "Could not create image buffer" and crashing after installing a videocard GeForce GTX 1070.

  Hi all

  I recently installed a GeForce GTX 1070 video card and drivers current in my bench mounted, very happy for the potential break in the rendering and playback (I was using previously a very old ASUS Radeon HD 7850). I had nothing else problems since.

  When I first tried a project of creation of opening, audio refused to play (speakers, headphones, everything...) I looked at the volume mixer while playing through the timeline and no audio only showed upward). Everything seemed fine. I closed, cleared the cache, opened the first, this time hold Alt while doing so to reset the preferences. Open very well, audio read back fine, that only now first was blocked indefinitely the generation of PEK files for a short audio clip in the project.

  After a long bit of troubleshooting in the speakers, I went ahead and did a complete uninstall of Premiere Pro and After Effects, then reinstalled both programs to their current versions (2015.4 and 2015.3, respectively). No more problems of generation PEK, but something much worse. Now, whenever I try to change the CUDA acceleration enabled, I can maybe five minutes absolute performance first until I get an error "Could not create image buffer", warning of notifications of Windows that your computer is low on memory, and finally, a complete crash where the screen goes black, flickers a couple times, then stays black for good with only the mouse cursor appears on the screen.

  The images that I'm editing is all images Go Pro, no effects applied. I am doing this for a client and need ready in a week, but the constant crashing makes them difficult to work around. I can more or less run by changing the acceleration of software only, display options but it is much slower and the memory is still eaten up like crazy (if I place the open Task Manager and start to scrub through the timeline I can watch the memory usage get up to 95% in 20 seconds approximately). Reading suffers as a result once the RAM is full until almost full.

  Technical specifications

  It is worth noting that, with my old dusty Radeon GPU, I was able to edit these clips with ease. No reading, no problem of image buffer. I do not see my RAM never go above 60% usage, when I got this card is installed.

  Also worth noting, that the first, I have noticed absolutely no problems, and the video card itself seems to work very well. I can play MGSV at max settings with perfect reading, as well as other graphics intensive games.

  Any help?

  It's been almost a week and I had zero problems. First Pro CC 2015.2 works like a dream! I'll go ahead and mark this thread closed.

  For those just tuning, I was able to find a solution by uninstalling the Premiere Pro and After Effects, and then reinstall them back to last known stable on my bench (Premiere Pro 2015.2 and after 2015.2 effects). So far, running these versions has been very good, even with active CUDA acceleration.

  The only downside is that all the projects I've done in Premiere Pro version 2015.4 should be re-edited from scratch. But I've had absolutely zero problems using the program, which is a relief. Hope Adobe fixes this problem whenever 2015.5 is out!

• How to create this type of drop shadow to a vector

  Hello!

  I wanted to ask you how to create this type of drop shadow to a vector in illustrator. I've seen these files and tried a lot to create that effect

  

  The shadow under the letters make this beautiful banner.

  Any help would be appreciated.

  I wouldn't have the effect of "vector". I could do this:

  1. Select the text object
  2. The background/contour value 'None '.
  3. Add 2 attributes of filling level of the objects in the "appearance" Panel
  4. Give the top of the page a 'white' and low 'Black.
  5. Select the fill 'Black' and it has an effect of "blur".
  6. Set the transparency of the fill black to "multiply".
  7. Save the appearance as a 'chart' Style and assign to each character separately

  If you want to change the character of a select skin, make the changes, and 'Option' drag the thumbnail from the appearance on the graphical Style available today. The changes will appear at any location, the Style is used.

  

• What settings to use in Photoshop to create images for 42 "LCD TV

  Hello world

  I hope you can help me please:

  I want to do a video advertising in store for a store selling at retail.  I use Adobe Photoshop to create images and create the movie using Windows Live Movie Maker.  The film runs on a 42 "Hannspree LCD TV.

  Question

  Should what settings I use in Photoshop for this TV?

  For example, I choose file > New > Preset: Film and video > size:... .but what size?

  Is there a certain pixel size, aspect, resolution etc, I need to know to LCD TVs or design in general?

  Here's a picture where I need help:

  

  I noticed that Windows Live Movie Maker has an option of image format, such as:

  

  But I still want to know what settings to use in Photoshop.

  Sorry for the question long and if the solution is real obvious - I'm a newbie!

  Hi Bazraam

  This is the setting I would use. I normally would raise the resolution to 300 just in case I want to print the image, but if not 72 will work fine

  

• How to create a type for an enumeration definition

  Sorry for this question of newbe, but I'm working on cleaning up my Act by using types of producer/consumer for event driven state machines.  To do this, it is convenient to create a type definition for the control of the enumeration that defines the possible States of the loop of the consumer.  I don't understand all of the discussion in the books I read.  I just placed an enumeration of control on the front and edited the State names, using them to define the queue for the loop of the consumer.  However, when I use the other functions of the queue and create a constant for the State to put it on the queue, a constant gets shot at the time of its creation.  If the list of States is modified, the item queue using the defined constant previously shows a symbol of constraint (red dot) and the constant does contain not the new State potential... is what the type definition is to propagate this definition to the constants so that they keep up with additions to the list of enumeration...?

  I've been playing with a short example to see how it works.  If someone could help me with something of definition, I would appretiate it.

  Thank you

  Hummer1

  Hi Hummer1,

  Follow these steps:

  1. under the 'file' menu, select 'new '.... »

  2. a dialog box will appear.  Select "custom control" and click "ok".

  3. a new façade will pop up, called "control1.ctl".  Put your constant listed on this new façade.  Add all your statements for your state machine, the way that you did.

  4. under the menu on your new custom control, you will see a field called 'control '.  Click on it and choose 'type definition' (or 'type strict definition').

  5. save your new control custom as "states.ctl" or "enum.ctl" or any name strikes your fancy.

  Now, go back to your main VI.  In the palette "orders", click on "select control".   Choose the typedef, that you just created.  Put it on the front panel.  Right-click on it and select "search terminal.  Your block diagram will jump upward and terminal control will be highlights.  Right-click on it and select "change constant.  Now, you can wire this constant in your queue.  Do the same for any other subVIs that use the same queue, so that they you are referencing the typedef.

  When you want to make changes to your control, open it in the same way you would open a VI and make the changes.  Then, under the "file" menu, select "apply changes".  Changes will propagate through all your screws

  I have attached a small example of a typedef for you.

• IMAQ Cast Image error

  Hi guys!

  So I installed a program using a camera and an analysis of the image. It works fine on another computer, but during the installation of this second system, I get:

  

  The research I found: http://forums.ni.com/t5/LabVIEW/imaq-cast-image-error/m-p/3217035/highlight/true#M934230
