  Hello

  How can I search for 32-bit in .csv file usinf labview 8.6.1 hexadecimal number

  Mathan,

  This post was not really a solution.  He just ordered Sandy to post in the appropriate forum, which we now know is LabVIEW 8.6.1 LV.

  Sandy,

  You want to read the text file, then use the search/Split String function to find the matching characters that make up your hexagonal pattern.

  What you ask is a little strange wordly since .csv files are text files, and you ask a "32-bit hexadecimal number.  Can you give an example of what you are looking for?  My response assumes you have a 8 string that consists of the characters 0-9, A - F for catch the 4 bytes.  Maybe you are dealing with just 4 bytes that present themselves as ASCII characters in a text file.  In which case you wouldn't have one. CSV file.

  If the response of research/Split String is not useful to you, you will need to provide details about what you are looking for and also an example of your. CSV file.

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

  Hello

  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.

  Thank you

• How can I display the time of the data stored in a file using labview?

  How can I display the time of the data stored in a file using labview?

  Hi Matt,

  I think that we will need a little more information as to how you capture the data, what data you capture, etc.

  If you capture a waveform, is to extract the time data waveform which includes the t0 and dt values, so you can understand the time stamp of a specific data point as in the image below.

• a 16 bit saved TIFF file does not work in ImageJ

  Hello

  I have a camera that records a 12-bit TIFF file.  When I have a saved TIFF file, it can be opened in ImageJ and all pixel values are preserved.  Also, if I display in Labview using IMAQ, it can be displayed properly and if I use ImageToArray, all values are correct too.  However, if I save it in a new file using written IMAQ 2 file, the saved file can be loaded in Labview with the correct pixel values, however, if I open this file saved in ImageJ, all the values are converted to 16 - bit wrongly.  For example, the value 62 (00111110) becomes 1000000000111110.  Apparently, the first figure when converted to 16-bit, it designates the first bit to 1 instead of 0.  I'm confused because the same saved when the image loaded into labview vi, the value is 62.

  Is it possible to fix it?  Could this be a problem with ImageJ instead of labview? I joined the original file and save the file here.

  Greetings, Charles;

  After looking at the attached screenshot, I have a question for you. Which is currently connected to the IMAQ Create for Source2? I guess it is an enumeration with I16 selected, correct?

  The same thing happens if you use U16 times on LabVIEW and ImageJ, or any lower bit depth? Finally, if you save the image to a different file format, you get similar behavior?

  Best regards;

• Is there a simple way to convert the bits to 16 bit depth?

  It seems there are specific methods PDF/BITMAP to convert 8-bit depth, but I can't find any documentation to make it easily the file as a whole. Is there a way to do this? I want to convert from 32 to 16 bit.

  I have the Image Processor Pro code that looks like this:

    // Bit Depth
    var bd = toNumber(task.@bitDepth) || 0;
    if (bd) {
      var bpc = doc.bitsPerChannel;
      try {
        if (bd == 8) {
          doc.bitsPerChannel = BitsPerChannelType.ONE;
        } else if (bd == 8) {
          doc.bitsPerChannel = BitsPerChannelType.EIGHT;
        } else if (bd == 16) {
          doc.bitsPerChannel = BitsPerChannelType.SIXTEEN;
        } else if (bd == 32) {
          doc.bitsPerChannel = BitsPerChannelType.THIRTYTWO;
        }
      } catch (e) {
        LogFile.logException(e, "Error selecting bit depth " + bd);
      }
    }
  

  Then, later, I have this code that modifies the document mode so that you can save it as a bmp file:

    if (ImageProcessorOptions.JDI && ext == "bmp") {
      // We need to make adjustments depending the number of
      // bmp save bits selected
      if (saveOpts.depth == BMPDepthType.ONE ||
          saveOpts.depth == BMPDepthType.SIXTEEN ||
          saveOpts.depth == BMPDepthType.TWENTYFOUR ||
          saveOpts.depth == BMPDepthType.THIRTYTWO) {
        saveOpts.rleCompression = false;
      }
      if (saveOpts.depth == BMPDepthType.FOUR ||
          saveOpts.depth == BMPDepthType.EIGHT) {
        doc.changeMode(ChangeMode.GRAYSCALE);
      }
      if (saveOpts.depth == BMPDepthType.ONE) {
        if (doc.mode != ChangeMode.BITMAP) {
          doc.changeMode(ChangeMode.GRAYSCALE);
        }
        var cnvtOpts = new BitmapConversionOptions();
        doc.changeMode(ChangeMode.BITMAP, cnvtOpts);
      }
    }
  

  I don't think I've tested with PDF files.

  I hope this helps.

• How can I search for integer of 32 bits in .csv file

  Hello

  I'm working on a project where I need to store the serial number of 32-bit in .csv file. I am convert the hexadecimal number of 32-bit hexadecimal string and writing to spread sheet. I want to compare each new number with the number stored in the .csv file. How can I do this?

  Thank you

  Hi Sandy, some details in your question make me think you develop your LabVIEW application: If this is the case, you should repost this question in the appropriate forum, since this one is dedicated to LabWindows/CVI and its users.

  If this is not true, to be more specific in your question, as I have caouldn can't understand weather you are puzzled by reading from the CSV file or by comparing numbers.

• How to read the bits of the file?

  Hello everyone,

  I am a beginner in LabVIEW. I need to get the bits of the file, but I don't know how I can do it. I use the example of 'Read Binary File VI' the help of LabVIEW, but it returns table DBL. And for a long time, I can't find a way to convert this table to table to bits. Can anyone help me? Thanks in advance.

  It is a very vague question. A file is nothing more than a long string of bits, so you could simply read a string and analyze the bits you like. I don't know how you do what they

  One possibility would be to cast to an array of U8, then use 'number of boolean array' in an autoindexing FOR loop, followed by the fitness in an array of Boolean 1 d. You can also format the U8% 08 b and concatenate the strings. There is no "official" way to represent the "bits" to the human observer.

• With the help of a PC with PS5 and need to open BMP files. Everything speaks of a format ad on. Where it is located or is - it possible.

  Using a PC with Windows 7 and 64-Bit Photoshop CS5 Extended. I work with the old digital files saved in BMP format and unable to open. Help talk an ad - for various formats, where do you find such an animal, it is still possible.

  You shouldn't have any add-on to open an image file in BMP format. Photoshop.exe a BMP file format support open and save images in BMP format should not be a problem. You can use BMP files you can't open it in Photoshop with other programs like the viewers the Image and paint programs that support the *.bmp files? Your file is possibly corrupted.

  Camera raw Adobe gives me 8-bit and 16-bit option for files to open, but my camera works with 14 bit (canon 6 d), what to do? If I get 8-bit option that I don't take advantage of the 14 bits on the other hand if I go for the option of 16 bits (as says that my files are 14) what's happening?

  Photoshop will work with the 14bpc data in the raw file, don't worry about this. The options that you mention "workflow" and apply to the final rendered file opened in Photoshop (bit depth, color profile, pixel dimensions and the value of the PPI). "16bpc" of Photoshop (15 + 1) is the only option if you need more output 8bpc ACR.

• I have some 24 and 32-bit PNG. On the bridge Panel, I don't see the value of bit depth.

  I see the value of bit depth (8-16-32) for the PSD but when I generate a .png32 that this value does not appear on the Bridge Panel file properties; I check on Panel detail of Windows image viewer and it says 32 bit. Thanks for your help!

  Hi iolnation,

  No, Bridge does not show the depth of bits for PNG files. You may apply for a feature on the link below, telling them why it is important for you to see the depth of bit for PNG in Bridge. I'm all for anything that will affect better PNG.

• HDR Lightroom "will not support the bit depth.

  I tried to merge the 3 files with HDR in Lightroom raw, Photoshop with 32 bit is set and then back to Lightroom.

  Once I saved the file in photoshop, it automatically loaded into LR, but said he could not handle the bit depth, when I tried to make adjustments.

  Any suggestions will be greatly appreciated.

  Make sure that you save the file in mode HDR 32-bit TIFF and PSD not.

  

• Problems with the PDF any bit depth

  

  The left image is a view in Acrobat Pro to an original file. It also appears correctly in the Indesign document in preview high resolution. The right shows the result after an export to PDF of this document of identity.

  The background color of the original image is a 4-bit RGB bitmap image; on the right, Acrobat Pro claims that it is now "24-bit". The original image can be changed by editing with Photoshop (he claims that it is an "unsupported color space"); refrying the original by printing a second time for PDF does not work, because the image remains unchanged. Change the color on the inside space the original PDF leads to the same result (changes the color space, but the bit depth remains the same). Open the entire PDF file in Photoshop gives the same result, as shown on the right (because apparently the PS can not handle this 4 - bit color space).

  The only way of setting the color space that has worked so far is to open all PDF in Illustrator and re-save AS. However, Illustrator converts * some * vectorised text (without specifying why, because it is all Arial).

  Any suggestions on how to solve this problem while maintaining the original vector data?

  (OT, but worth noting anyway: I had to connect (waiting), go to the forum ID (wait once again), find a ' Post' button which worked (new waiting) and try to write this mail in 3 different browsers.) IE does not work - you cannot insert an image and expect to be able to type text. Firefox took so long to load even the text editor that I dropped. Chrome works - slowly. Certainly room for improvement here.)

  edited by retouching with Photoshop (he claims it is an "unsupported color space");

  It is true that Photoshop is the Mode of Bitmap 1 bit and modes of 8-bit in levels of grayscale, Duotone and color Index with nothing in between.

  I guess you tried to export with compression and a sampling turned off?
