• several images capture and read their path to send the byte array to the web service

  Hello

  Have a problem when the image capture, the requirement is to open the camera and capture multiple images, and once done it should send the array of bytes to the web service, wrote the class with reader and Video Control of the code and then using the saved file to store image API, but when the user capture multiple images it replaces previous if I keep the path to say dynamic by using the date and time then how I just know what images are recently captured and their path, one time I know that the path of recently captured using new fileconnection images can read the image byte array.

• 5.1 Lightroom ceased to import JPEGs of iPhone. The iphone and the images will be displayed, but import said that they cannot be read. This has just begun. Even the phone, IOS and the OS.

  5.1 Lightroom ceased to import JPEGs of iPhone. The iphone and the images will be displayed, but import said that they cannot be read. This has just begun. Even the phone, IOS and the OS.

  The message 'could not be read' indicates you do not have WRITE permission on the destination folder. So, here's what you need to do

  1. The Lightroom Import dialog box, go to the Destination section to the right and make a note of the specified folder.
  2. Change the folder to something else; OR in your operating system, change the permissions on this specific file WRITE permission.

  }

  }

  }

  You can recode this treatment so that it uses only:

  e.nextElement ())

  Once a loop iteration.

  Directly at the start saying something like:

  String fileName = e.nextElement ());

  and use fileName everywhere in your loop.

  Also be aware that printStackTrace() will do nothing in your situation, it only works if you catch Throwable.  So make sure you something output all your catches exception and also have a catch (Throwable t) to catch the things you miss, as follows:

  {} catch (Throwable t)

  t.printStackTrace ();

  System.out.println ("Eception exception:" + t.toString ());

  }

  I think your code is thrown an exception and you don't see it.

• Microphones capture multiple producers/consumers

  I was getting buffer overflow problems when I used foolishly multiple "Capture sound" Express VIs to listen to several pickups and treat them.

  I then created a structure of producer/consumer where I realized 2 signals (2 producer loops) and loop them into 1. It was working fine!

  I developed this idea today to 3 microphones (and hoped for later). The problem is that I get the errors again. I can't quite explain the errors, so I have attached the images (in sequence). By highlighting the execution, it seems that the error occurs on the SECOND iteration of the "Sound Input read" in each 3 loops "producer".

  I hope someone can shed some light on this issue. Seems strange that it would work for 2 microphones, but not for the 3.

  I tried briefly to play with the sampling rates high with no apparent result.

  Try to double the number of samples to get into configuration VI while leaving many points before reading VI the same.  The configure VI defines the size of the buffer.  The VI read the entry defines how many points is read at each iteration.  The buffer must be always bigger than the number of points, read so the computer has between the buffer time for enough points to read and read the real no overflow (which seems to be your problem).  Adding another entry added more charge processing, maintenance if the bed is now produce not fast enough (the computer unless a sampling period unique answer to avoid an overflow).  I made that mistake myself more than once.

  ==========================================

  You can do the Panning... with Photo Story 3.

  (FWIW... it's always a good idea to create a system)
  Restore point before installing software or updates)

  PhotoStory 3 for Windows
  http://www.Microsoft.com/download/en/details.aspx?ID=11132
  (works on XP, Vista and?) Win7?)

  This is not a full tutorial, but should be enough to help you started...

  First be sure that the photo is less than 7200 x 7200 pixels pixels.

  Import a panoramic photo in Photo Story 3 and move on
  the screen "tell your photos and customize the animation."
  (do not remove the black borders)

  On the left, click Custom animation...

  Check the box on the screen to customize the animation...... "specify
  Start and end Position of the movement "." Resize and reposition the
  Start management Position and final Position you prefer and
  on the left, click the Preview button to see the result.

  Also you can import multiple instances of a photo and
  Pan from point A to point B in the first instance,... then point B
  point c on the second instance and so on.

  When the effects of movement are completed you can add music if
  you want and go to the screen "Save Your Story."

  You can left click on the 'Settings' button for several choices of
  resolution... the profile of 1024 x 768 is perhaps a good choice.

  Also... Choose a backup location and a name for your video.

  To save the project as a. WMV video file... click Next
  last time.

  Then you can import that video as well as other photos and
  video clips in DVD Maker to create your DVD. If you have
  problems with the video clips you may need to convert to MP4
  paste them into WMV format before importing in creation of DVD.

• Could not watch television and the images are black and white on Qosmio

  Hi, live Saudi Arabia
  I have problem with my TV Tuner. When I scan the channel it is find frequency for some channels, but cannot look at them!

  also when I try to capture using model-SVIDEO color balck & white that I try to use PAL nothing changed
  And thanks for the help

  Hello

  One question; Did you purchse the notebook in your country?

  I guess that the black and white image appears on the TV. Am I wrong?
  This can happen if the TV doesn t s-video or if the s-video option is not enabled on the TV.

  In addition, I would recommend to check the version of the driver installed tuner.
  Then go to the page of the Toshiba driver and check the version of the tuner driver.
  If the new driver is available, so please download and install on the Qosmio.

• Capture of sequences of images - issues with nested for loops

  Hi all

  I've written a vi. to capture a number of images ("Image") and save these images, sent to a folder of my choice.  Each image is identified sequentially.  However, I would like to make a number of iterations ("run") of this capture sequence, such that each image file name would be "Filename (Run) _(Image_No).png", for example run 5, image 10 'Filename 5_10.png.  I tried a nested for loop for this but I have an error message 'Current asynchronous i/o Operation' (I have attached a printscreen).

  Can someone help me solve this problem?  Please find attached my vi.

  Sincere greetings and thanks,

  Miika

  Hi toto26,.

  Thank you for your response.  I solved the problem by using a sequence structure flat - file in the first image and all the treatment in the second.

• The most effective way to log data and read simultaneously (DAQmx, PDM) high data rates

  Hello
   
  I want to acquire the data of several Modules cDAQ using several chassis to
  high data rates (100 k samples per second if possible). Let's say the measurement time is 10 minutes and we got a large number of channels (40 for example). The measured data is written to a PDM file. I guess, the memory or the HARD disk speed is the limits. For the user, there must be a possibility to view the selection of channels in a graph during the measurement.

  My question: what is the best and most effective way to save and read data at the same time?

  First of all, I use an architecture of producer-consumer and I don't want to write and display the data in the same loop. I expect two possibilities:

  [1] to use the 'DAQmx configure logging.vi' with the operation 'journal and read' to write the data to a PDM file. To display the data in a second loop, I would create a DVR samples documented and 'sent' the DVR for the second loop, where the data will be displayed in a graph (data value reference). This method has the disadvantage that the data of all channels is copied into memory. Correct me if I'm wrong.

  [2] use 'DAQmx configure logging.vi', but only with the "journal" operation to write the data to a PDM file. To view the selected data, I had read a number of samples of the TDMS file in the second loop (I'm currently writing the TDMS file). In this case, I have only one copy data from the selected channels (not), but there will be more HARD drive accesses necessary.

  What is the most effective and efficient solution in this case?

  Are there ways to connect and read data with high frequencies of sampling?

  Thank you for your help.

  You say that the measurement time is 10 minutes. If you have 40 channels and you enjoy all CHs at 100 kHz, it is quite a number of values.

  In this case, I always try to approach under the conditions of use. If a measure is only 10 minutes, I just connect all PDM data and create a graphic module that could be in the same loop of consumers where connect you the data. You can always work on the raw data files big offline afterwards, the extraction of all the information you need (have a look at the product called NI DIAdem: http://www.ni.com/diadem/)

  The main issue is that the user needs to see in the graph (or perhaps a chart can be useful too). Lets say that the graph is 1024 pixels wide. It makes no sense to show multiple data to 1024 points, Yes? Every second will produce you 100 data points k per channel. What is the useful information, which should see your username? It depends on the application. In similar cases, I usually use some kind of data reduction method: I use a moving average (Point by point Mean.VI for example) with a size of the interval of 100. This way you get 100 data points of 1000 per channel every second. If you feed your graph every second with these average values, it will be able to data points in 1024 of the store (as a default) by channel (curve), which is a little more than 10 minutes, so that the user will see the entire measurement.

  So it depends on the frequency at which you send data to the consumer. For example, collect you values 1024 by iteration of the producer and send it to the consumer. Here you can make a normal means calc or a bearing (according to your needs) and he draw a graphic. This way your chart will display only the values of the last 10 seconds...

  Once I programmed some kind of module where I use a chart and not a graph, and the user can specify the interval of the absolute timestamp that is traced. If the data size is larger than the size of the chart in pixels, the module performs an average calculation in order to reduce the number of data points. Of course, if you need to see the raw data, you can specify an interval that is small. It all depends on how you program zoom functions, etc... In my case I hade a rate of 1 Hz, so I just kept all data in RAM limiting the berries to keep 24 hours of data, so that technicians could monitor the system. In your case, given the enormous amount of data, only a file read/write approach can work, if you really need access to all of the RAW data on the fly. But I hope that the values of working capital means will be enough?

• Emulator CVS displays bitmap color black and white images

  I use a VBAI2009 inspection on 1454 CVS which uses a camera firewire AVT Guppy F - 036C. This system is on a production machine inspect the product we make. VBAI uses the legacy IMAQ for IEEE 1394 on a CVS not the driver IMAQ-dx cameras. The VBAI script contains several steps function color inspection. To get the AVT camera to display the color, I had to install the files of MAX camera using the Bayer color tab because Bayer settings are not accessible from the driver on the CVS IMAQ. I'm no adjustment of the camera of the VBAI. This configuration works well and has worked for 6 months on the machine of production without any problem.

  Now, I need to edit the VBAI script but can't stop the machine to make the changes and test the program. I captured images bitmap using MAX during the inspection was installed 6 months ago and they stored on my host for just such an occasion. I am using these captured images and the CVS emulator in VBAI to make the changes to the program offline. I performed the inspection under the CVS emulator and the acquisition stage is configured to point to the captured bitmap images using the button Configure Simulation settings. The problem I have is that bitmaps are displayed as black & white in the emulator, even if these are images of color seen with paint. I can't find a way to fix this. Is - this problem as a result of using the parameters of Bayer to create the image color or something else in the emulator? The emulator, no installation of color image treats?

  Any help would be appreciated,

  Mark

  The stages of acquisition camera record video mode information used to acquire images. If you use these steps in emulation mode, it converts the type size and the image to match what has been gained for calibration and processing step use the same type of image. Looks like than the stage thought that the image was mono, even if you got it to be color. I will consider how it could have be saved incorrectly when you use the settings of Bayer. In the short term, you can disable the acquisition stage (don't delete so you do not lose the camera settings saved in step) and use a stage of acquisition of simulation or a new phase in the acquisition of 1394 and won't force the image size/type.

  Hope this helps,

  Brad

  When you select B & W, the JPEG image will be B & W, as well as the JPEG image of reduced resolution which is embedded in the RAW file. When you open the RAW file in your computer, you will be able to see the color, but the color will not appear when you use the camera playback function.

  Hi Anton,.

  I didn't know this, but looking at the code my guess is that there are actually other locker that holds a write lock, but he released the writer lock just after the time waiting and before we created the message you see. So unfortunately, the message is not useful for you.

  Is your app lock multiple records using both bed and written? If so, it's probably a blockage due to the locking control. If you try to reproduce several times, I hope you can see the real cause. Or maybe you can find the problem of code inspection.

  Readings never block readings, of course, as you said.
