• Change Ctrl.Val.Get or binary write format of LV8.5 until 2014

  Hello

  I have recently updated from LV8.5 to 2014 and a problem of compatibility. I used the Crl.Val.Get method to get an array of values and save them in a binary file:

  

  to read later with a binary read:

  

  My problem is that the files generated in this way with LV2014 (64-bit) cannot be read by LV8.5 (32 bit) - the result is a "LabVIEW: Unflatten or stream of bytes read operation failed due to corrupted, unexpected or truncated data" error or an application crash.

  Writing binary VI changed of LV8.5 ro 2014? Is this a problem for 32/64-bit? Oddly enough LV2014 reads the files generated with LV8.5 without problem. Is it possible for me to this LV2014 program to ensure backward compatibility with LV8.5 (something that I need for a prolonged transition period).

  Kind regards

  Casper

  About, unless you set the binary file format exactly (for example define how you store the data in the file until the byte level) I'd be dubious on the file is readable in the new/old versions of LabVIEW - especially if you are using types of complex data as of the beams.

  Dealing with backward compatibility would be either define the binary file format and work to that or use a file format string in function (e.g., JSON, XML, INI) for which you can write a compatible rear parser. The OpenG library has screw for saving/loading of the controls in the Panel before a VI in an INI file, for example (even if OpenG stop supporting, it's a format string in function, so you can always write your own parser if you need to in the future). I know that don't helps you you in your current situation, but maybe something to keep in mind for the future.

• Write a bmp to binary questions

  Hello

  I have a string of text BMP I got an oscilloscope of Yokogawa. I can write this file directly to a. BMP, but binary writing adds 4 bytes at the beginning of the BMP string that actually a BMP format invalid. Remove the 4 bytes with a text editor, save, and reopen the case it will be valid which can be opened by any image viewer.

  I also tried the regular script text file function, but it's the jarbled of the image, however, does not add the 4 extra bytes as a binary writing.

  And I tried the recommendation of this post, but the BMP file is also jarbled.

  Here's my VI:

  

  Writing the file binary write, extra 4 bytes...

  

  I see here the 4 bytes in the data string.

  

  What happens if you wire a FAKE on the array or string of size "prepend" when writing the binary file? (the default is TRUE).

  (If you use 'write in the text file' be sure "convert EOL" is disabled (it is enabled by default).)

• IMAQ write bmp conversion problem

  I automatically tries to get a 3-d chart to write the content of the image in a bitmap image, I am currntly using the property node "get image", and then the bmp.vi 'write' but gives a bitmap of poor quality as well. I found simply right-clicking on the front panel and with the help of "copy data" and then paste it into ms paint gives really good quality. (see attachment) So:

  There are two ways to write a bmp file, as I discovered: [n/b, I am running 8.2 lv]

  writing bmp.vi & imaq write bmp.vi

  the bmp.vi of writing requires an input of a cluster with the image data it contains in the form of a 1 d table, the bmp of writing imaq simply to an input image.

  Q: is there a good way to convert between them as the bmp.vi of writing returns less Muslim bitmaps imaq writing bmp.vi is capable of.

  Or is it a way to dirrectly read an image other than 'get image' use 3d as a method node? or data 'copy' lets get data wrote?

  Chears John P.

  Hi John,.

  If you set number of bits of the image get invoke node to be 24, that this feature will also define the bitmap that you write to drop to 24 bits.  Simply connect to a constant of 24 to terminal nodes invoke bit depth.

• Use to write key VI with a table of cluster

  Hello

  I wanted to use an array of clusters to define certain configuration settings for an application. Unfortunately, 'Write key VI' does not support the type of cluster. Has anyone modified this function ('write key VI') in support of cluster and cluster table? Otherwise, no idea to keep it as simple as possible?

  My clusters include boolean, path, U32 and string.

  Thank you

  Olivier

  FYI, I have eventually save the cluster as a binary ("Write to binary function') file and a VI to read/write it. Is the easiest way for me as the other functions seem to have a limit on the complexity of the clusters they can handle.

  Thnaks for your suggestions,

  Olivier

• Cluster of savings in the form of binary data

  I have a compound cluster of ~ 50 items of different types that I need to save it as binary data. Obvoiusly I could do with the method of "brute force" of 50 different entries in the file, but that seems silly.

  Is there an easier way to empty just the disk in the form of binary data?  By registering as a cluster seems to add extra characters.

  In a world of LV, I just recorded in as a variant, but it must be saved as binary raw in order to be read by another program as a C structure.

  There is the beautiful Boolean entry in the binary write for "add/array of strings of size."  Unfortunately, this boolean applies only to the type of upper-level data that is being written.  So whatever it is inside the cluster will always these lengths prefixed.  Therefore, you have to separate your data and write each piece individually.

• format of binary data in labview 8.6 or more

  I'm writing a binary file in LV8.6 to an array of clusters in which each cluster has many types of data in it including more tables and clusters. I want to read that data in a MatLab program, but nothing is read correctly.  It seems also that there is change between after labview 7.x where the type defs have been written in 16-bit before now are 32-bit. and I can find no documentation on how the binary write function stores the data of complex data types.  Any search for documentation on the site of labview brings just hundreds of visits irrelevant.  I try to read the binary file in matlab and I don't see any numbers expected coming out.

  Someone at - it a link to where I can get the specifications for LV > = 8.6 binary formats.  Or full of info on flatten channel for new versions of labview.

  Thank you.

  The format of the flattened data is documented in the help of LabVIEW. In the contents tab, expand Fundamentals-> how LabVIEW stores data in memory-> Concepts-> data flattened.

  The flatten the string function only saves the data, not the structure. You think of Type descriptors. Yes, it has changed in LabVIEW 8. BT 7, they were 16-bit. BT 8, they are 32-bit. It is also documented in the help of LabVIEW.  Fundamentals-> how LabVIEW stores data in memory-> Concepts-> Type descriptors.

• write the bmp incompatible aid

  In labview 2011, the help on the bmp 'writing' vi reference is different from what is shown in the dialog using the schema context of the block for the necessary data types.  The reference to assistance to the first (2) elements of the cluster as U16 and U8, image type and image depth, respectively.  However, context-sensitive help shows these two as I32 (I just plugged a wire cut at the entrance of 'image' on writing in the comics and on bmp icon context-sensitive help, which displays the data expected for this entry).

  Which is correct?

  The function is correct, the file of detailed help associated with this function does not.

  Interestingly, the BMP reading help file shows the correct data types.

  Good fishing!  A person of OR will probably issue a CAR # to have corrected documentation.

• Easily accessible images AVI - BMP Conversion extraction

  Hi, Im at a roadblock now, I have to extract frames of an AVI video then convert BMP images and load/apply a texture to an object in a 3D scene. Now the problem is not extract frames, Ive managed to extract the images using the available screws of AVI IMAQ but Im stuck after that.
  I found the 'writing BMP file' VI under the utilities of Vision, one of the terminals of the VI says 'File path' which means the way he's going to write the file is now? Or...?
  Secondly, I can't find a way to load/save lots of BMPS at the same time. The texture that I apply to the object comes to a BMP image (and in this case, a lot of BMP images extracted from AVI video) just by using the "Read file BMP" vi, which leads to the directory/path of the BMP on the PC. This is where the problem lies, I need the vi 'Read BMP file' was updated constantly, every 'x' seconds to account for the number of frames / FPS of the video then she reads each frame of the video as its update. But if I need to save the accquired executives AVI MPG I don't see a way to do this.
  Any suggestions would be greatly appreciated.

  Hi again

  I hope that your application is on the right track now. I found other examples for the avi feature, so I'll add the links below.

• How to record a bit 2D array in .bmp file?

  I'm new to LabVIEW...

  I have a 2D binary table and I want to record to file .bmp. The .bmp file must be 1-bit bit depth in order to satisfy the devide requriement.

  I tried to use flatten pixmap , but there only 4-, 8 - and 24-bit pixmap options for table 2D. 1-bit pixmap is for Boolean table entry.

  I don't know how to convert the bit 2D array in the array of Boolean or any other method to resolve this problem.

  Thank you are to help.

• Conversion of .bmp in .png in LabVIEW

  Hello

  Is there a way to convert the files bmp png using LabVIEW?

  Thank you.

  The graphic palette has functions for reading and writing files bmp, png and jpette.  So you can just read bmp and then write png with image data cable connected between the two.

• Opening writing BMP.vi DLL

  I'm trying to convert IMAQ images BMP images without the need to use the BMP.vi to write, because the process of writing BMP files in a directory then reading/loading them becomes slow with huge data files. I opened write it BMP.vi and found a DLL inside that I'm assuming that performs this conversion. I don't seem to be able to open it in Visual Studio? Any particular reason for which his hidden?

  Hello Nik@Bris

  LabVIEW is unfortunately not a package of software open source. Therefore, it is not possible for the clients to access the dll written by National Instruments LabVIEW.

• Convert bmp to jpg

  I am trying to order photos that were sent to me using Photosmart. Unfortunately they are BMP, and I need to convert them to JPG format. I know I did in it happened but didn't write the instructions. I thought I would remember, wrong again. Help, please. Thank you

  Hello khadija

  Unless you have used a 3rd party program allows you to convert images with Microsoft paint. Just open in paint and choose "Save as" and choose jpeg. The disadvantage of this method is that you must manually convert each photo.

  Just a friendly reminder of jpeg is of lower quality than BMP.

  If this does not help, I hope you remember how you converted your photos above.

• Batch export of .eps to .bmp files created eps files / have additional

  A simple action.

  1. File > export > .bmp
  2. Close

  If I run the action on a single file, it works perfectly.

  If I try to run as a batch, it creates fine bmp files.

  But it also creates a file .ai or .eps MyFile.htm!

  Write one or two additional files increases shows the process down.

  After the execution of the batch, it is not difficult to simply delete the additional .eps/AI, of course.

  But write these files seriously slows down the process, and I have about 89 000 files more go.

  Illustrator CS4.  Windows XP

  Oops, never mind.

  The fact that the action has worked with a single file, but creates additional files in the batch should be a clue that the problem was my selections of batch processing dialog.

  I changed the Destination of the "file" to "None" and all is well.

  Duhhh.

  Two thousand down, 88 000 to go!
