• Polygon color with RGB U64 images / Image conversion of RGB U64 in RGB U32

  Hi guys,.

  I want to use the color polygon feature, but I have an input RGB U64 image. The only supported is image RGB U32 type. Is it possible to convert the image to U64 U32 and use the color polygon feature?  I know I'll lose accuracy, but what for the moment.

  Otherwise, you know the functions of polygon that supports RGB U64 images as input?

  Please let me know.

  Thank you

  IMAQ Cast Image VI Converts the current image type for the image type specified by Type of Image.

  How Casting works: The VI shifts the value from the source to the range of 8-bit using the depth of specific bit of the source image. Then the VI defines each color component in the destination value for the corresponding component in the value of the source.

• SGL and variable U32 are wired to same variable DBL through the structure of the case, block data poster SGL DBL during case U32.

  Hello

  Here, I have attached an example, similar code module is used in our project.

  In this example in the control of two structures business SGL and U32 panels is directly related to the signpost DBL. If I give 4294967295(U32 value of maximum range in the case of forgery under the example) its display 4294967296.

  Please give me the solution to show the correct value of U32 in signpost DBL.

  Thank you

  Wherry

  In your code, 4294967295 is first converted to the SGL (on the edge of the box structure), then to the DBL. But this value may not be exactly converted SGL (due to lack of significant digits).

  You should convert the SGL DBL value in the case of true.

• How to divide numbers (U32 to U8)

  Hello

  How to cut a number of byte values (U8)? I found the 'number of Split' - thing in labview. What should I use twice to U32? (first 32-> 2 x U16 and U16-> 2xU8).

  Or is it also a more rapid/more elegant way to do it?

  Thanks for help

  You can simply use the Cast of Type function to convert an array of U8.

  

• U32 + "digits of precision" (?)

  Hello

  What is the meaning of this behavior?
  Is this expected behavior? and, if so, why?

  I asked this question before on the french forum (french is my mother tongue)... here ... but I don't have all the answers.

  

  For a U32 (even for an I16, I32, U16,...), is it normal to be able to define the "digits of precision?" (for me, which is meaningless)
  In addition, this may cause display errors (79,99999..)

  

  What is your opinion of that?

  Thank you all (and sorry for my bad English)

  Digital controls is not an entire display format, just a floating point format.  It is also probably related to the other s format that would apply legitimately to integers, (such as scientific notation which would use two decimal values and still be an integer 1 million = 1e6 999,9999 would be 9.99999e5.

  So, you take an integer value, and it passes through code designed to return the floating-point values and also technical and scientific notation.

  There is no specific reason why you do not want to display an integer with digits after the decimal point, so 0 digits of precision would be normal.  But there is no reason to prevent a person only to display decimal digits.   And when you get down to the display of 16 digits of precision, it doesn't surprise me that you reach the limits of numbers floating point, which is the underlying code that should be used to display decimal values on integers.

  At the end of the day, I think that this could be considered expected behavior and not anything that anyone would cause problems in the practical world.

• Set the format digital u32 when writing of TDMS files

  We use two meters of a PCI-6251, with two counters in the mode of angular position, to measure the angular positions of the two optical encoders 1000 per second for intervals of 10 to 20 hours.  We are writing to write files using PDM.  The files are very large, about 800 MB, but it is acceptable.  Convert us the TDMS files in .txt files, and then the data from .txt files are analyzed in Mathematica.

  My question is: How does one control the digital format of the data that is written in TDMS write?  At this moment we have two counters of the value of the product N = 10000 numbers U32 samples are then transmitted continuously to a TDMS file every 10 seconds.  The counters are using units of ticks (integers) and we would like to see whole in our data files.  We are convinced that the counters are producing U32 to the format number, since we see the correct U32 integers in the indicators on the front panel and we see labels on the value axis on our waveform graphs are integers, not real numbers.

  But it is also clear that Scripture TDMS puts double-precision (64-bit) numbers floating point in the PDM file, not numbers of U32.  The double-precision floating-point numbers cause our .txt files to be twice as big as they should be - these .txt files are half full with useless zeros and decimal points.  In addition, when you convert the U32 to double-precision real numbers, it seems to be a loss of precision as a result of writing of PDM, which is not acceptable.

  Our experience produces pairs of integers: U32 (or I32) format.  We could even get away with numbers I16.  Is it possible to get our data to stay in U32 (or same I16) format when they are written to the TDMS file?  What controls the digital numbers written to tdms?  Do all the numbers written in a PDM file end up being written as floating-point numbers double-precision?

  We use LabVIEW 8.2 on a PC running windows XP.

  If associate you TDMS write U32 data, data in the file will be U32. Floating-point conversion probably occurs when you read data from the file back. You can change this by plugging in a U32 empty table at the entrance of 'data type' reading PDM.

  You can check the data type in the file by examining the channel properties in the viewer of TDMS files. If NI_DataType is 7, given in the file are U32. If it is 10, data are floating point.

  Hope that helps,

• How to convert U32 matrix 8-bit grayscale image?

  Good day to all,

  I got a U32 512 * 512 data table of photomultiplier using the analog inputs of the DAQ card. My question is how to convert this matrix 32-bit to 8-bit monochrome image for display.

  I tried the method in this post to convert grayscale image https://decibel.ni.com/content/docs/DOC-4155 table but the result resembles an outline rather than the actual image. I guess that's because their contribution to flatten Pixmap is 8 bits, but mine is 32-bit. I have a gamma correction to the scale of my data? But how?

  I have attached the original image, which is a particle. I have also attached my labview code and the processed image.  Thank you!

  Then, you will likely make you own custom conversion then increasing the difference between the brightest and darkest. You could just do 4294963840 the zero and 4293967276 the max and scale up to 0-255

• CWIMAQdx.GetAttribute failed to get attributes in the string or format U32.

  I'm reading all the attributes of a Gige camera. I can get the I64, F64 attributes and Boolean marker. But when the type is string or U32, the returned object "attribute" is "NULL". Can someone let me know what is wrong with my code?

  Thank you

  object attribute = new object();

  if(stype=="I64")

  {

  CWIMAQdx.GetAttribute (sid, attributeInformationArray [i]. Name, CWIMAQdx.ValueType.I64, out attribute);

  sValue = Convert.ToInt64 (attribute). ToString();

  }

  If (sType is "String")

  {

  CWIMAQdx.GetAttribute (sid, "attributeInformationArray [i]. Name', CWIMAQdx.ValueType.String, out attribute);

  sValue = Convert.ToString (attribute);

  }

  If (sType is "U32")

  {

  CWIMAQdx.GetAttribute (sid, "attributeInformationArray [i]. Name', CWIMAQdx.ValueType.U32, out attribute);

  sValue = Convert.ToUInt32 (attribute). ToString();

  }

  Is it just a coincidence that in your second two cases (you mentioned do not work) your code example seems to be passing the constant "attributeInformationArray [i]. Name"rather than the actual attribute name?

• Is it possible to separate the U32 value in four U8 values?

  Hi all...

  I work on a project where I need to use electronic load and set it to different values... To connect with electronic load, I need to give orders in format HEX... The format I should use is an array of U8 byte 26... Each byte is dedicated to an end... As

  byte 1 - bit of departure

  2nd byte - address

  3rd byte - order

  4th byte - the lowest byte of the value of the voltage

  5th byte - the lower byte of the value of the voltage

  6 bytes - the higher the voltage value byte

  7 bytes - the highest byte of current value

  and the manual says

  "represent the voltage of 4 bytes of HEX. Lower byte are to the site before, upper bytes are in the location of the latter. For example: voltage is 16.000V, HEX code is 0X00003E80, 4th byte of 0x80, 5th byte is 0X3E, is 6 bytes 0 x 00, 7th byte is 0x00. »

  in the program, I take the user input voltage which, in decimal format, like 16V... Now rest work should be done by software converting it to HEX n which separates it into 4 bytes. Enter in the table...

  My problem is that I am unable to separate from U32 to U8. Can someone help me please...?

  Thank you.

  Hi mohamed,.

  You can use 'divide the number' to get what you need.

• How to convert an integer U32 in ascii?

  I am communicating with a digital camera. I can send it commands and receive ascii as output. In many cases, the data I receive are in packets, which I decode. When I combine my 8-bit with the function array of build, I get a whole U32. Currently I'm only converting an integer U8 and displays the result as a rev program. We want to display as an ascii value, and I was unable to find a way to do it. I am including a screenshot where I'm doing the conversion. Thank you!

  Hi SciManStev,

  What do you mean with ascii value? If you need a string, you can use the function 'type cast '.

• U32? I32

  Hello

  Why "LV" uses "I32" rather than "U32"... While the result is never negative?

  for example:
  -output 'shift spent some number' service 'chain of decimal number '.
  -the terminal loop of an iteration loop While, or a loop For...
  -output 'size' of the table size function

  What is the significance of a 32-bit signed integer to an outcome that will never negative?

  Why developers labview make that choice?

  I guess that's to make it coherent and so having less stress points. For example, the output of the table 1 d research must be I32 since it returns a negative value if there is no match. If wire you a - 1 to an array of index, you get the default value for the data type of table.

  It is the same for many other places where the negative (-1) has a similar meaning. Then there will be many points of coercion if LabVIEW use U32 where a value can be positive only (like the size of the array) but I32 where it can be positive or negative.

• The most effective way to the U16-> U32 Array pack for DMA data transfer?

  I have a RT controller who wants to send data to an FPGA using DMA.  In LabVIEW 8.2, I have no choice but to switch to the low blocks of data however U32 my my input data is an array of U16.  This leaves me two choices: 1) wire U16 table directly into the DMA node that will be rude to U32 but I lose 16 bit * #of table 2) Pack the U16 elements in a U32 table before sending it to the bottom.    I have #2 and I have a method that works (and seems to be quite effective) but I have the feeling that I'm doing the hard (or roundabout way).   Is their a simpler (but equally effective) way to do this procedure?  Thank you

  Here's a solution that swaps the bytes and key elements the same. There are several ways to do so.

  

  (for efficiency, you can place the table 'remodel' inside a case structure then, it happens only if necessary)

• Need help to create a U32

  I'm trying to access a function in a DLL that was created by a programmer here. Authorware tells me that the DLL does not contain the function, I'm calling.

  Does anyone have any documentation on how to package this DLL as being a U32?

  Thank you

  Mark

  Discover the installation of Authorware CD. It has all the information you need to create the dll and u32s. You may find that you do not see the function is because you have not entered the correct arguments.

• WINAPI.u32

  Has anyone got any technical information on this file? In my tests, I know that it is temporarily created in the folder of files authorware users as a piece of Authorware is running on the web and is deleted when the module closes. I also discovered that, for example, the object of knowledge slipped seems reoly to this topic somehow. I would like to know what it is, why it is used and is necessary for the functioning of the Authorware and what depends on it. Thank you

  WinAPI.u32 is a 'wrapper' for a large number of functions that are
  presentations in Windows. Exposes the Windows API in an easy to use
  format of Authorware developers. Look in your custom functions dialog box
  and you can see what functions are responsible for him, to see what exactly
  your piece relies on it.

  Insofar as it has been deleted after the releases of the piece, it is indeed the
  default action, but if you specify "Recycle" for it (whether in a
  Editing, or directly in the aam file button) it will persist between
  tracks and not need to be downloaded again. This is the default for
  Xtras, so take a look at the Mao to see the flag on one of the Xtras for

  Hi all
  I solved this problem. :-)
  I had copied all the files I thought I had to record that I was saving my files. Unfortunately I had also copied the 'user32.dll' as well.
  Removal of the extra "user32.dll" in the saved folder solved the problem.

  The moral of this story is aviod using the dll in the system, DO NOT COPY dll system to your application package and don't EVER published with your application.

  Hope this helps someone.
