Analysis of the binary file when writing of a 2D array

• Adds data to the binary file as concatenated array

  Hello

  I have a problem that can has been discussed several times, but I don't have a clear answer.

  Normally I have devices that produce 2D image tables. I have send them to collection of loop with a queue and then index in the form of a 3D Board and in the end save the binary file.

  It works very well. But I'm starting to struggle with problems of memory, when the number of these images exceeds more than that. 2000.

  So I try to enjoy the fast SSD drive and record images in bulk (eg. 300) in binary file.

  In the diagram attached, where I am simulating the camera with some files before reading. The program works well, but when I try to open the new file in the secondary schema, I see only the first 300 images (in this case).

  I read on the forum, I have to adjust the number of like -1 in reading binary file and then I can read data from the cluster of tables. It is not very good for me, because I need to work with the data with Matlab and I would like to have the same format as before (for example table 3D - 320 x 240 x 4000). Is it possible to add 3D table to the existing as concatenated file?

  I hope it makes sense :-)

  Thank you

  • Good to simulate the creation of the Image using a table of random numbers 2D!  Always good to model the real problem (e/s files) without "complicating details" (manipulation of the camera).
  • Good use of the producer/consumer in LT_Save.  Do you know the sentinels?  You only need a single queue, the queue of data, sending to a table of data for the consumer.  When the producer quits (because the stop button is pushed), it places an empty array (you can just right click on the entry for the item and choose "Create Constant").  In the consumer, when you dequeue, test to see if you have an empty array.  If you do, stop the loop of consumption and the output queue (since you know that the producer has already stopped and you have stopped, too).
  • I'm not sure what you're trying to do in the File_Read_3D routine, but I'll tell you 'it's fake  So, let's analyze the situation.  Somehow, your two routines form a producer/consumer 'pair' - LT_Save 'product' a file of tables 3D (for most of 300 pages, unless it's the grand finale of data) and file_read_3D "consume" them and "do something", still somewhat ill-defined.  Yes you pourrait (and perhaps should) merge these two routines in a unique "Simulator".  Here's what I mean:

  

  This is taken directly from your code.  I replaced the button 'stop' queue with code of Sentinel (which I won't), and added a ' tail ', Sim file, to simulate writing these data in a file (it also use a sentinel).

  Your existing code of producer puts unique 2D arrays in the queue of data.  This routine their fate and "builds" up to 300 of them at a time before 'doing something with them', in your code, writing to a file, here, this simulation by writing to a queue of 3D Sim file.  Let's look at the first 'easy' case, where we get all of the 300 items.  The loop For ends, turning a 3D Board composed of 300 paintings 2D, we simply enqueue in our Sim file, our simulated.  You may notice that there is an empty array? function (which, in this case, is never true, always False) whose value is reversed (to be always true) and connected to a conditional indexation Tunnel Terminal.  The reason for this strange logic will become clear in the next paragraph.

  Now consider what happens when you press the button stop then your left (not shown) producer.  As we use sentries, he places an empty 2D array.  Well, we dequeue it and detect it with the 'Empty table?' feature, which allows us to do three things: stop at the beginning of the loop, stop adding the empty table at the exit Tunnel of indexing using the conditional Terminal (empty array = True, Negate changes to False, then the empty table is not added to the range) , and it also cause all loop to exit.  What happens when get out us the whole loop?  Well, we're done with the queue of data, to set free us.  We know also that we queued last 'good' data in the queue of the Sim queue, so create us a Sentinel (empty 3D table) and queue for the file to-be-developed Sim consumer loop.

  Now, here is where you come from it.  Write this final consumer loop.  Should be pretty simple - you Dequeue, and if you don't have a table empty 3D, you do the following:

  • Your table consists of Images 2D N (up to 300).  In a single loop, extract you each image and do what you want to do with it (view, save to file, etc.).  Note that if you write a sub - VI, called "process an Image" which takes a 2D array and done something with it, you will be "declutter" your code by "in order to hide the details.
  • If you don't have you had an empty array, you simply exit the while loop and release the queue of the Sim file.

  OK, now translate this file.  You're offshore for a good start by writing your file with the size of the table headers, which means that if you read a file into a 3D chart, you will have a 3D Board (as you did in the consumer of the Sim file) and can perform the same treatment as above.  All you have to worry is the Sentinel - how do you know when you have reached the end of the file?  I'm sure you can understand this, if you do not already know...

  Bob Schor

  PS - you should know that the code snippet I posted is not 'properly' born both everything.  I pasted in fact about 6 versions here, as I continued to find errors that I wrote the description of yourself (like forgetting the function 'No' in the conditional terminal).  This illustrates the virtue of written Documentation-"slow you down", did you examine your code, and say you "Oops, I forgot to...» »

• The binary file format

  With the help of LV2010.  I have a program that stores data in a binary file.  The file is a set of strings and floating point values.  I need to write another program in VB.NET that can save/read these files, so I need information on the actual file format of the data.  Is there a documentation which describes how the file is saved?  Thank you.

  Interesting. Usually, this question gets asked in the opposite direction with people trying to decode in a cluster.

  If you use the WriteToBinary function, your data are written as native data types in order to cluster in the binary file. Because you use a cluster, each string is being preceded by a length, which I believe is an I32.

  This is described in the help file for writing to a binary file. I think the people of thing travel length of string/array much however.

• Keep the text formatting when writing new file with FILEIO

  Hi all
  
  I wonder if there is a way to keep the formatting of the text when I write it in a new file using FILEIO. In particular, I have the following text in a domain member:
  
  test < background = L1_garaz / > (text in the tag a color and itsbold) test
  
  
  I use the following code to write the foregoing in a new filw using FILEIO:
  
  on mouseup
  
  
  Annot = member("annotator").text
  path = the moviepath & "Annotated_text\".
  whichanno = baGetFilename ('Save', ' "& path &" "," "," doc files | ") * .doc", 0, -2, 0, 0, 'save the doc file')
  
  myanott = new (xtra "FileIO")
  
  myanott. CreateFile (whichanno) - create
  myanott.openFile(whichanno,0)
  writeString(myanott,annot) - write the new string
  myanott.closeFile)
  myanott = CANCEL
  
  end
  
  the problem is that despite the type of file I want to choose to save it (.doc, txt, etc.), he refuses to save the text with its original formatting (with the colors and the words "BOLD"). No idea how to solve this problem?
  

  Use a member of text instead of a field member, then you can access the formatting of the text through property .rtf... then save this info to a file:
  Annot = member("annotator").rtf
  .....
  ...
  writeString(myanott,annot) - write the new string

  Quote:
  Posted by: wgb14
  NOP, its said property found rtf. So if saving to RTF (without change to the ownership of the member("annotator") still once he will not keep the main text formmat

• How to determine the size of the binary file data set

  Hi all

  I write specific sets of data in table in a binary file, by adding each time so the file grows a set of data for each write operation.  I use the set file position function to make sure that I'm at the end of the file each time.

  When I read the file, I want to read only the last 25 data sets (or numbers).  To do this, I thought using the position set file to set the file position where it was 25 sets of data from the end.  Math easy, right?  Apparently not.

  Well, as I was collecting data file size as I began the initial tet run, I find the size of the file (using file order size and get number of bytes so) as the size increases the same amount every time.  My size and the format of my data being written is the same every time, a series of four numbers double precision.

  I get increments are as follows, after the first write - 44 bytes, after 2nd - 52 bytes, 3 - 52 bytes, bytes 44 4th, 5th - 52 bytes, 6 - 52 bytes, 7th - 44 bytes and it seems to continue this trend in the future.

  Why each write operation would be identical in size of bytes.  This means that my basic math for the determination of the poistion of correct file to read only the last 25 sets of data won't be easy, and if somewhere along the line after I've accumulated hundreds or thousands of data sets, what happens if the model changes.

  Any help on why this occurs or on a working method, all about the problem would be much appreciated.

  Thank you

• Analysis of the log files from vCenter

  Hello, a virtual machine has been removed in our area, and I need to analyse what/how it happened. Unfortunately, the vSphere and vCenter log files have since turned.

• How can I maintain the original size of the JPEG file when you import into Photoss?

  I noticed that when I use pictures to import images from the SD card in the camera, the images are substantially smaller than when I drag the same image directly from the SD card on the desktop. In general, a 3.6 Mb picture somehow diminishes to about 2.6 MB. I'm wrong and get frustrated to this drop in image quality!

  Any help / advice will be highly appreciated. Thank you

  In what circumstances you see this small size?

  Photos did a bit of copy bit when importing images in its library.  If you drag the thumbnail of an image on the desktop you bet that the preview version, which will have a small file size.

  Export the image on the desktop via the file export Export X Unmodified Originals ➙ ➙ menu option will give you the full size file that was imported into the library.

  Drag the thumbnail on the desktop will get you the original file.

• How to ensure that the binary file is stored in the location specified for my DLL files?

  I'm new to computers and has a Dell Inspiron 1545 laptop with a program in Windows Vista Home Premium on a 64-bit platform. I have a thread in my sidebar gadget new MSNBC and the dates for the stories are frozen in December of last year and does not update the current stories. I had no problem with this before and I haven't added or deleted programs because of this problem to the best of my knowledge. I got advice here on the checking of dll files and 4 of them come back with saying error messages and see that the binary is stored at the specified location for debug files. I searched for information help with this and I found a few tips that not saved and re-entered the files, I tried and different versions of the idea, at first it made no difference and then I redid it and it screwed up my weather gadgets so I redid it and they worked very well. I then tried on the DLLs for the MSNBC gadget, but it doesn't seem to change anything, although the gadget to power for the Dow Jones News feed is now screwed up. Is there a site I can go to what can explain the route of binary/specified path or debug file. Save/re seems to be the right path, it affects obviously the gadgets but not as I want, any help in this direction would be appreciated at. Meanwhile I'll go back and try again.

  Hi dumdeedumdum

  
  What are the files dll are facing problems with?

   

  You can perform a SFC scan and check if the problem is resolved.
  To Perform a Scan SFC -
  a. click Start, click programs, on Accessoriesprincipally made, right click guestand then click run as administrator. If you are prompted for an administrator password or a confirmation, type the password, or click on Allow.
  b. type the following command and press ENTER:
  sfc/scannow
  A message appears indicating that "the system scan will start. Be patient because the scan can take some time.
  c. If all files require a SFC replace will replace them. You may be asked to insert your Win7 DVD for this process to continue.
  d. If everything is correct you should, after the scan, see the following message "resource protection Windows not found any breach of integrity".
  e. once the scan is finished, close the command prompt window, restart the computer and check.
