• Convert a table to a cluster of 4 elements array values 2D 2D double precision, or a table 1 d

  Y at - it an easy way to convert a 2D cluster table (4 elements each including a Boolean value and three numbers dbl) to a table 2D or 1 d of double precision values? I need to store my data in a text file to control a robot, I'm trying.

  Thank you.

  There are 1 million different ways to do it. The best thing to do would be to leave the data exactly as it is and simply use Flatten in XML format (search the palette). It accepts virtually any type of data, including a 2D cluster table as you described. He will spit human readable (although not necessarily nice) text that you can write to a text file. Then, read you data from the file and use Unflatten of XML to do the reverse.

  Or you can use a similar model to flatten your data in a 1 d of double table which you can then unflatten.

  

• Can I enter both a table and a constant of double precision in the VI form?

  I would like to calculate a new 1 d array using the formula VI. LabVIEW 'smart enough' to enter a 1 d table and a double precision constant in the VI form and leave a 1 d table receives basic commands?

  For example, can I enter [1 2 3] table and the constant [2] and say "table * constant-1" in the VI form and get an output of [1-3-5] or do I have to make a loop for or something?

  The Express VI formula seems that it can have up to 8 inputs.

  Twolfe, the best way to find an answer to this type of question is to try it.

  I didn't know this (because I have no reason to use that express VI), but you can wire a table to it.  He treats like any other LabVIEW operation on arrays.

  But if you were to make a loop, then you should already be avoiding Express VI and start making actual emissions.

  

• VISA Read Double Precision Corruption number with the 2400 Keithly

  I am confused on this point.  I have two systems with built in GPIB Controllers PXI.  Among the randomally systems began to show the behavior where the double precision read data returned orders gibberish.  On the other system, I use the same code and everything works.  Chain controls standard job very well (voltage value, current value, query set of voltage etc.).  I tried the following:

  Reset computer

  Keithly instruments exchanged (the problem follows the PC)

  Exchanged GPIB cables

  Update driver 488.2

  Used separate HS-USB-controller GPIB.

  I will be reinstall NI-VISA as well.

  The only difference is that I installed a few other drivers LeCroy instrument to the failed system.  But the problem is a not deliver after I installed the drivers, it occurred during the performance of my code.

  Has anyone ever seen this before?  What could be other causes?

  The problem was with the Keithley, change the format of the data without my knowledge.

• Will I lose data conversion to double precision single-precision float?

  Before you say Yes...

  I use a crio unit in scan mode interface. Which returns the mode of scanning values in floating point double precision. Apparently I'm supposed to be able to choose between double precision fixed-point ("not calibrated") and ("calibrated") floating point data, but this feature seems to be exclusive to the fpga interface and is not available with the scan engine. The two data types are 64 bits per value, when it comes to the size on disk, anyway is still basically the same.

  The system continuously records 13 channels of comma floating double-precision at 200 Hz. using the binary file write, I measured it is about 92 MB/hr on the disk. (more than 120 MB/hr with PDM and much more to write on the worksheet) In short, this 92 mb/hr rate is just too much data on the disk on this system.

  The modules that I record since, 9236 9237 and 9215 c-series modules, have 24-bit a/d converters or less. Does this mean that I have not need 64-bit to represent the number and accuracy even?

  Can I force/cast point values double-precision floating that I receive of the variables of e/s scan engine to the data type of a different, smaller, as a single-precision floating point and retain the same precision?

  You can test it by looking at the difference between a DBL and converted to SGL DBL. But I support the Nickerbocker trick. I don't think it will make the difference

• AE never use 'double precision FP64' calculation of Visual effects?

  I'm trying to find out if after effects never really use double precision calculate what whether or not. I know the basis of coding video is really ever use it, but I wonder if the particle effects benefit from double precision or if it's mostly to single precision.

  I am currently using a GTX black Titan, which has a good amount of double precision performance, but I don't know if I ever really use it. I'm looking to the new Titan X, which essentially replaces the power of calculation of double-precision with even more unique precision. I especially to create the content of the game in real time and can always benefit from the upgrade of single precision performance, but I also use After effects a good amount and won't lose boosts performance in it. I can get more benefits on the Titan X because that all rendered I do generally is through converters of cpu and no gpu converters, but I do not know what changes After Effects has achieved since CS6.

  Totally irrelevant. Effects like Particle World are not the same hardware accelerated, so what might even be the point on single-precision and double-precision? And for all purposes useful, it is even irrelevant if that were the case - many pixel operations and position related calculations are quantified / integer for which single precision is sufficient. Double-precision really only countries out for complex vector operations where rounding errors for example can mess with for dynamics or similar collision detection.

• images in double cancellation

  Hit girl copy in the image folder and copy all the images as duplicate. can I cancel it. or need to delete individually. We are talking here about 5000

  If the copies are in the same folder with the original... and the
  folder is still open... you could try to go to... Change / cancel the copy.

  If the copies are in the same folder with the original... and the
  file was closed, reopen the file and the file
  names.

  If each duplicate file name is preceded by the words... "Copy Of"...
  Find the folder of the copy and delete them all... thus leaving
  the originals.

  When all the "copy of" files are displayed... go to...
  Edition / select all
  Drop / delete

  It is a complete and separate folder copy... could you
  Right-click right/delete the folder.

  If you delete the wrong files... Look in the trash
  and you may be able to recover.

  Good luck...

• Why my screen background image get doubled in size all of a sudden?

  My background image screen is all messed up.  I changed the image and now every photo, I try to set as background is too much and very grainy.  I have no idea of what happened, and I'm sure it's an easy fix... I don't know what it is.

  Change your resolution to a native of your screen:

  Start > Control Panel > appearance and personalization. Click personalization, click display settings. Under resolution, move the slider to the right size. If you have a laptop or a flat screen monitor, using its native resolution. Native resolution of your laptop in the documentation provided with your computer (which can be in a file on the hard drive) and will also be on the mftr computer tech support site. for your model. Native resolution of your screen will be in the documentation that came with the monitor and sometimes on the protective plastic sheet that was covering the screen.

• Elimination of the double precision

  I must eliminate double vagueness with math real number in my application, but I cannot understand how to use the BB API. I tried to write a method that checks for series 9 and 0, and rounded up to the previous digit upward or by eliminating the final figures, but my method caused too many problems.

  Edit: I would like to give an example of the error:

  I expect this result: 0.0002

  But after some calculations double to keep the result, the program returns 0.0002000001

  Any ideas on how I can eliminate double vagueness?

  Thank you

  Scott

  Thanks for all the answers. I forgot this thread, but remembered it when the problem came once again.

  I solved the problem by using whole mathematics instead of double math, and I use indexOf(".") for formatting integers. It was actually a relatively easy solution.

  Thank you

• images in double Muse

  I am building a Web site with about 360 images in what I put there.

  The entire site has more than 2300 images, most are small Muse generated jpgs and 8px small square square colored, rendered text in menus accordions for the selection of the page - if you click on a square to go to a page. It seems to me that rather than having just a few small places that reuses of each page, what I have is multiple images - one for each instance of something on every page - including the navigation on each page.

  There are 80 odd pages and muse about 765 generated small squares that total more than 6 MB in the image folder. The menus are on 3 master pages, and each is identical (other things vary). Menus to take a while to load and I guess that's because they use somehow 6Mo to a value of small squares - how can I simplify this? The squares are background colors in the text without text box. It would be more logical to make the squares a fill of an image file, rather than a background color in the text box?

  I wonder also why Muse would make the small jpgs places instead of png, for a single color tiny place, I would have thought would be a smaller file?

  There are other items that I have repeated on each page via copying and pasting and each of them is in multiple too... they're all rendered text, but identical.

  Is there an easy way to muse to use only a single instance of an image if it is repeated elsewhere - especially with those that it restores? I thought to replace the text rendered by one of the images generated through html, but this seems a bit laborious, I was expecting something more easy.

  Thanks for your help, I hope this makes sense.

  See you soon

  template to reuse images... that's what a master's. example of Master A has your background colors (images) then Master B {a Master A as its master page} adds a menu bar and Master C is the next change. This design of the chain DASYE made Master used by every page of your site, because all the other Master pages link to it.

• Possible bug: save the table with double and extended precision to the worksheet

  If one concatenates an array of double-precision and an array of precision extended with the 'build' vi table, then recorded using 'Write in a spreadsheet file' vi any digits to the right of the decimal are reset to zero in the saved file. Regardless of the entry of signifier of format (for example %.10f) to the vi 'Write in a spreadsheet file'.

  I'm on Vista Ultimate 32 bit and labview 9.0

  This is a possible bug that is easily circumvented by the conversion of a type before you incorporate arrar in a worksheet. Nevertheless, it's a bug and it cost me some time.

  Hi JL,.

  No, this is not a bug - it's a feature

  Well, if you'd look closer you would recognize the 'save to spreadsheet' as polymorphic VI. As this polymorphic VI does not support the EXTENSION numbers internally (it only supports DBL, I64, and String) LabVIEW selects the instance with more precision: I64 (I64 a 64 bits of precision, DBL that 53...). Your options are:

  -the value of the instance to use as the DBL (by right click and "Select type... »)

  -make a copy of this VI, save it under a different name and make support number of POST (not rework the polymorphic VI like you would break compatibility with other facilities of LV or future revisions)

• ORDImageSignature SQL/MM still Image

  Hello
  
  We have migrated our application from Oracle 10 g to Oracle 11 g.
  All our images are stored in the database as ORDImage.
  And I've been using ORDImageSignature for image comparison.
  
  But as ORDImageSignature methods are amortized in Oracle 11 g, it seems I have to use standard methods SQL/MM still Image to make the comparison of images.
  
  < li > here is how I made the comparison of the image using ORDImageSignature :
  

  procedure link_photo_to_point(in_pt_id in number, in_img_id in number, out_message out varchar2) is
       l_exist number := 0;
  begin
       select count(*) into l_exist 
       from photos inner join photo_components on phco_phot_id = phot_id
       where ordsys.imgsimilar(phot_signature, (select phot_signature from photos where phot_id = in_img_id),'color=1,texture=1,shape=1,location=1', 0, 1) = 1
       and phco_spatial_id = in_pt_id;
       if (l_exist > 0) then
            dbms_output.put_line('Error : a similar photo is already linked to the point' || in_pt_id);
       else
            insert into photo_components(phco_spatial_id, phco_phot_id) values (in_pt_id, in_img_id);
            dbms_output.put_line('The photo was successfully linked to the point' || in_pt_id);
       end if;
  end;

  < li > and here's how I'm trying to do the same thing using still images SQL/MM :
  

  procedure link_photo_to_point(in_pt_id in number, in_img_id in number, out_message out varchar2) is
       l_exist number := 0;
       l_score double precision;
       l_img_obj si_stillimage;
       l_img_blob blob;
       l_featurelist si_featurelist;
  begin
       select p.phot_source.source.localdata into l_img_blob from photos p where p.phot_id = in_img_id;
       l_img_obj := new si_stillimage(l_img_blob);
       select count(*) into l_exist from photos p inner join photo_components on phco_phot_id = phot_id
       where l_featurelist.si_score(new si_stillimage(p.phot_source.source.localdata)) = l_score
       and phco_spatial_id = in_pt_id;
       if (l_exist > 0) then
            dbms_output.put_line('Error : a similar photo is already linked to the point' || in_pt_id);
       else
            insert into photo_components(phco_spatial_id, phco_phot_id) values (in_pt_id, in_img_id);
            dbms_output.put_line('The photo was successfully linked to the point' || in_pt_id);
       end if;
  end;

  And of course, I get the following message displays as I do not know how to fill in the si_featurelist variable, so it can contains the features of the image...

  ORA-30625: shipping method on the argument NULL SELF is not allowed

  I think that the documentation is not clear on how to do it.
  
  Any help would be appreciated.
  
  Thank you.
  
  Yann.

  Okay, I think I've found my mistake. Here's what I did:

  First, I tried to add a new column to the PICTURES table to store directly the subject of the photo :

  alter table PHOTOS add phot_source2 SI_Stillimage;
  update photos p set p.phot_source2 = si_stillimage(p.phot_source.source.localData) where p.phot_id < 10;
  

  It worked.

  Then I set up a minimal example that compares the image 2 for the first 10 images of the PHOTOS table:

  DECLARE
       l_img_obj     si_stillimage;
       l_avgcolor     si_averagecolor;
       l_colorhist     si_colorhistogram;
       l_poscolor     si_positionalcolor;
       l_texture     si_texture;
       l_featurelist     si_featurelist;
       l_blob          BLOB;
       l_count          INTEGER;
  BEGIN
       -- get the blob from the ordimage
       SELECT p.phot_source.source.localdata
       INTO l_blob FROM photos p
       WHERE phot_id = 2;
       -- build the stillimage object from the blob
       l_img_obj := NEW si_stillimage(l_blob);
       -- get image features and build the featureList object
       l_avgcolor    := NEW si_averagecolor(l_img_obj);
       l_colorhist   := NEW si_colorhistogram(l_img_obj);
       l_poscolor    := NEW si_positionalcolor(l_img_obj);
       l_texture     := NEW si_texture(l_img_obj);
       l_featurelist := NEW si_featurelist(l_avgcolor, 1, l_colorhist, 1, l_poscolor, 1, l_texture, 1);
       -- check if a similar image is found in the table
       SELECT COUNT(1)
       INTO l_count
       FROM photos p
       WHERE si_scorebyftrlist(l_featurelist, p.phot_source2) = 0
       AND phot_id < 10;
       -- show message
       dbms_output.put_line(l_count || ' similar photo(s) found');
  END;
  /
  

  It worked.

  Then I tried to replace p.phot_source2 by si_mkstillimage1 (p.phot_source.source.localdata) (causing the problem), and it worked too!

  Then I tried to change phot_id < 10 < 20 phot_id, and finally it failed.

  So I finally understand that I had null values in the column ORDImage ... that was causing the problem.

  Indeed the call to SI_StillImage() with a null parameter gives the error in the above program:

  >
  ORA-06510: PL/SQL: not supported by the user-defined exception
  ORA-06512: at "ORDSYS.SI_STILLIMAGE", line 27
  ORA-06512: at "ORDSYS.SI_MKSTILLIMAGE1", line 6
  ORA-06512: at line 24
  >

  All works fine now.
  I hope that this thread can help someone else :)

  Good bye.

• reproduce the extraction method from page to page 5.0 09 image

  Hello

  (El Cap 10.11.3)

  In recent years, I supported pages 09 to my work as a storyboard artist. Now I would like to do some of my work on an ipad pro as well and this will require me to use the 5.0 instead Pages I need to used 5.0, even when working on my mackbook pro s think I canswitch between machines easily. Everything on the use of the pages 5.0 is great except one problem in my workflow that is as follows: I draw pictures on paper and scan them and make a folder of individual JPEG which I can plug into my model of Storyboard in Pages 09 (at this point, I can also type despcriptions and reorganize etc way Pages). Then (the important bit) when I need to see the images, I double click the cell 09 document containing the image that I need to change and appears as a jpeg icon in the settings window. I can then do it on the desktop and there in photoshop/manga studio where I do the modification. then save it, then copy paste image revised in place in the document.

  Could someone tell how can I reproduce it easily and quickly in Pages 5.0

  

  Above is Pages 09

  and even in the Pages of 5.0:

  

  Thanks for all the tips!

  In Pages v5, you click the image once and when selected, you can drag its icon on the desktop in the Image tab below.

  

• Visibility conditional image in DiAdem report

  Does anyone know how to make an image visible conditional in a DIAdem report?

  I want to do is display a certain image .jpg in the report based on a property of a data file loaded into the portal.  I'm creating a generic reporting structure that actively changes based on which file is loaded into the data portal.

  Someone at - he already tried it or even wanted?

  Steve

  Hi Steve,.

  I wanted to say after you have created the image object, double-click it, and THEN use to get all the properties.  I played with it earlier and found that you can set the size to 0 to hide it.

  Call GraphObjOpen ("Metafile1")
  
    MtaWidth  = 0
  
    MtaHeight = 0
  
  Call GraphObjClose ("Metafile1")
  
  Call PicUpdate

  As I said, you can also put this logic in the ' before refreshing: "field at the bottom of the 'Layout settings' dialog box, which is saved with the TDR file, and then runs whenever you refresh the chart.

  Call GraphObjOpen ("Metafile1"): MtaWidth  = L1 * 3: MtaHeight = L1: call GraphObjClose ("Metafile1")

  You can use an assignment IIf (Condition, TrueValue, FalseValue) rather than the stuff of L1, but you did not say me again what the visibility of the image depends.  Perhaps a property value in the data portal?
