• Calculation of frame rates of acquisition image using the 7 Format

  So I finally got my Basler firewire (IEE1394b) camera to capture images at his rate max (120 fps).

  But to do this, I need to use the '7' Format.... which is a bit confusing to me.  When I use the '7' Format, I can't specify the frame (frames per second) rate.  Apparently, you only specify the parameters (length, width, color / mono) of the image and the size of the packets and a few other things.

  So, how can I calculate speed?  I need to know exactly how much time elapses between each image.  And it must be constant.  I can't have a different frame rate.

  NEITHER told I can calculate the frame rate using this equation:

  

  That comes from this article.

  But I am skeptical because the article also says:

  Please note that the time to transfer an image is slightly faster than the time it takes to acquire an image.
  

  People out there can clarify this for me?  Is the frame rate constant?  And then I actually calculate when using size 7?

  The rate will be constant.  It won't change from image to image.  The difficult part is to find what it is.

  Basler camera manual will tell you how to calculate the frame rate.  There are three different calculations, and gives you the slower pace is one you use.  These calculations are accurate enough, I think.

  Another possibility is to measure the frame rate, but that requires several seconds (or minutes) for a measurement precise.  The simplest method is to start a life-long and save a frame in time at the beginning, wait several seconds (or minutes) and save the time of another framework.  Subtract the chassis numbers, subtract the time and divide to get the frame rate.  With a wait of several minutes, it's extremely accurate.  To get the acquisition time, read an image whose value "Next Image", then save the chassis number and read the msec timer immediately after reading.  Using a flat sequence structure is probably the best to ensure that everything happens in the desired order.  If you loop playback, you will see real cadence cadence converge slowly.  Stop it when it is pretty accurate.

  In a program I wrote, I controlled the pace by setting the shutter exposure time.  I used the derived formula of the Basler manual for cadence and reversed to calculate the shutter speed.  This only works if you have another way to adjust the brightness levels (opening, lighting, etc.).

• Problem using the pixel format indexed bytes in the PixelWriter setPixels method

  I'm trying to build a byte array and set it on a WritableImage using the PixelWriter setPixels method.
  
  If I use a RGB pixel format, it works. If I use a byte indexed pixel format, I get a NPE.
  Stride etc should be fine if I'm not mistaken.

          writableImage.getPixelWriter().setPixels(0, 0, imageWidth, imageHeight,
                                                   byteIndexedFormat, indexedBytePixels, 0, imageWidth);
          imageView.setImage(writableImage);
      }
  
  }

  If there is no solution, maybe someone knows a solution? We chose to use the format indexed due to the size of the data / performance reasons.

  You have found a bug in the platform, filed against the project to-online http://javafx-jira.kenai.com to your sample code and a link to this forum question.
  Byte indexed pixel formats seem like a feature never completely (or maybe even any) implemented for me.

  The PixelFormat type uses your unsuccessful case is (PixelFormat.Type.BYTE_INDEXED):

  PixelFormat byteIndexedFormat = PixelFormat.createByteIndexedInstance(colorPalette);
  System.out.println(byteIndexedFormat.getType());
  

  Here are the valid PixelFormat types =>
  http://docs.Oracle.com/JavaFX/2/API/JavaFX/scene/image/PixelFormat.type.html

  BYTE_BGRA
  The pixels are stored in adjacent bytes with the non-premultiplied components stored in order of increasing index: blue, green, red, alpha.
  BYTE_BGRA_PRE
  The pixels are stored in adjacent bytes with the premultiplied components stored in order of increasing index: blue, green, red, alpha.
  BYTE_INDEXED
  The pixel colors are referenced by byte indices stored in the pixel array, with the byte interpreted as an unsigned index into a list of colors provided by the PixelFormat object.
  BYTE_RGB
  The opaque pixels are stored in adjacent bytes with the color components stored in order of increasing index: red, green, blue.
  INT_ARGB
  The pixels are stored in 32-bit integers with the non-premultiplied components stored in order, from MSb to LSb: alpha, red, green, blue.
  INT_ARGB_PRE
  The pixels are stored in 32-bit integers with the premultiplied components stored in order, from MSb to LSb: alpha, red, green, blue.
  

  As for a WritableImage native pixel format is not the same that you use the pixel format, the JavaFX platform needs to do a conversion while reading pixels in a format and write it in another format. To do this, he must be able to determine a PixelGetter for your PixelFormat (the PixelGetter is an internal thing, API not public).

  And here's the source determines the PixelGetter for a given type of PixelFormat:
  http://Hg.OpenJDK.Java.NET/openjfx/8/master/RT/file/06afa65a1aa3/JavaFX-UI-common/src/com/Sun/JavaFX/image/PixelUtils.Java

  119     public static  PixelGetter getGetter(PixelFormat pf) {
  120         switch (pf.getType()) {
  121             case BYTE_BGRA:
  122                 return (PixelGetter) ByteBgra.getter;
  123             case BYTE_BGRA_PRE:
  124                 return (PixelGetter) ByteBgraPre.getter;
  125             case INT_ARGB:
  126                 return (PixelGetter) IntArgb.getter;
  127             case INT_ARGB_PRE:
  128                 return (PixelGetter) IntArgbPre.getter;
  129             case BYTE_RGB:
  130                 return (PixelGetter) ByteRgb.getter;
  131         }
  132         return null;
  133     }
  

  As you can see, the BYTE_INDEXED format is not supported, and null is returned instead... it is the source of your NullPointerException.

• Disabled IPad can be reset using the recovery mode

  Someone with a good it knowledge doctored iPad without permission and now it can be reset using the recovery mode. While that plugged into iTunes, software downloads, iPad, then displays the Apple symbol but then returns the message "iPad is disabled connect to iTunes".

  Hi stephen158,

  I understand that, in the process of restoration of an iPad in recovery mode, your iPad rebooted and returns to the screen "connect to iTunes". This can occur if the software download takes longer than 15 minutes, how the iPad will exit Recovery mode and the software will continue to download. In this case, you should be able to put the iPad in recovery mode and choose to restore the device when prompted.

  1. Connect your device to your computer and open iTunes. If you don't have a computer, borrow one from a friend or go to an Apple Store or service provider authorized Apple for help.
  2. When your device is connected, force restart it: press and hold the sleep/wake and home for at least 10 seconds, and only release when you see the Apple logo. Keep until you see the screen in recovery mode now.
     
  3. When you see the option restore or update, choose update. iTunes will try to reinstall iOS without erasing your data. Please wait while iTunes downloaded the software for your device.
     If the download takes more than 15 minutes the device out of recovery mode, you must repeat these steps and choose restore instead of update when you return to this step.
     
  4. After the update or restore is complete, configure your device. If you have backed up your device with iTunes or iCloud and you need to restore your device in step 3, you may be able to restore from your backup during installation.

  You can enable the detection of wrist as well as an access code and unlock it with the iPhone:

  • On your iPhone, in the application of the watch, go to: My Watch (low left tab) > General > wrist Detection - this turns on.
  • On your iPhone, in the application of the watch, go to: Watch My > Passcode > Passcode turn on (choose a Simple 4 digit access code or a longer).
    • Also in the password settings screen, select Unlock with iPhone.

  After putting on your wrist, your watch don't unlock then after whatever you do first: unlock your watch manually or unlock your iPhone. Then, it will remain unlocked until you delete the monitoring of your wrist, when that it locks automatically.

  You can also set your watch to the screen to reactivate automatically when you lift your wrist, even select what is displayed on the screen to wake up:

  Cannot left click to advance to the next image in the image windows Viewer. I can move forward using the keyboard

  I have a folder of photos that I opened to see several thumbnails. I can left click on a picture and it will open full screen. Then I left click on this image and the next should show but nothing happens. I can use the keyboard arrows to move to the next photo, but I can't use the mouse. The left click works for everything I use it for. I've used regsvr32 /i shimgvw.dll and he said DllRegisterServer and DllInstall in shimgvw.dll succeeded. This does not solve the problem.

• Can I still use the toner cartridge after deposit of 2 and a year and a half?

  I have a HP CE505A toner cartridge model in a sealed box, but the box have a date on it his 20111003 (I think that refers to October 3, 2011). Now my question is if I unseal the box can I still use the toner cartridge (whereas 2 years and a half elapsed from the date on the box), or if I buy another cartridge of toner?

  HP Laserjet toner cartridges are usually not a particular lifecycle or expirary date or end of warranty.

  You can use all your stored correctly with your printer laserjet toner cartridges & most probably you shouldn't find any problems or defects on them, until the cartrdiges are sealed pack & storage, or weather conditions (heat, moisture, and direct light from the Sun) did not cause any damage to the cartrdiges.

  Please consider reading this useful document related to the storage and handling of the HP laserjet print cartridges:

  I'M ON A WIRELESS SYSTEM TO RUN FAST, NOW I'M I'VE SEEN TROUBLE STREAMING MOVIES AND EVEN VIDEOS ON YOU TUBE, CAN SOMEONE ME USING THE ADVICE ON SETTINGS OF WINDOWS VISTA?

  Hi GrahamCroal

   

  1. is the streaming of films and videos slow down or you are totally unable to broadcast their?
  2. what exactly happens when you try streaming?

   

  You can check if the below link help-

  http://Windows.Microsoft.com/en-us/Windows-Vista/which-protocols-does-Windows-Media-Player-use-for-streaming

   

  Also the connection speed must be higher than the data rate of the content you read to discover Fast Streaming. The faster your connection, the better your experience will be. So it depends entirely on the broadband connection you are using and speed offered by the connection. If you want faster streaming then you need check the high-speed broadband connections. You can communicate with the internet service provider for more information about the same thing.

  I hope this helps.

• ScriptUI: get the dimensions of the container using the automatic formatting?

  No there is no way to get the dimensions of a ScriptUI container that uses the automatic formatting?  What container root (Panel or window)?  I'm writing a presentation for a group and I would like to react to the dimensions of the window or Panel, as it is resized, but it seems that this info is still not defined when the automatic formatting is used for containers of the ancestor.  No there is no way to know what size of the containers of the ancestor is without write handlers of layout custom for each of them?

  I think that it is either

  .size
  

  or

  .bounds
  

  which returns the values.
