• IMAQ flatten image for the 64-bit version of string

  Hello

  I noticed customer odd based on vision "flatten image chain" on labview 64-bit edition. In my program I use flatten image to the string (with compression to JPEG and kind of flatten Image) to compress and send data to another application. I noticed on the compressed image color missmatch. I say red (255,0,0) 32-bit RGB image and I flattened for string and then save this string as a binary JPEG using Write to vi. When I open the file of the picture is blue (0,0,255). It doesen't matter how data is written (big endian, little endian or native) the result is always the same. 32-bit edition Labview, the code worked correctly.

  I reported a bug in the NC and I'm still waiting for a solution to this problem.

  LabVIEW: labview professional development system 2010 32/64 bits (with vision development module) completely v10.0f2 lie

  Systems: labview 64 bit on windows 7 64 bit-> flatten image to string-> false color

  LabVIEW 32-bit on windows 7 64 bit-> flatten image to String-> colors OK

  LabVIEW 32-bit on windows 7 32 bit-> flatten image to String-> colors OK

  A picture of the block diagram that I used to test the conversion is attached.

  See you soon

  Hi 3DVision.

  I think I see the problem... you code looks like he expects that out of "flattening the image of the chain" will actually be a JPG file as a string, because you have chosen to use the JPG compression options. However, this is not the way that VI is intended to be used. It is simply a way to convert an image type of Vision in a string representation which can be easier to haul around (for example via the network, the user file format, etc.). It is a parallel to normal 'flatten' that can be used on any type of data from LabVIEW. The format of this string is the owner and has provisions for storing information that is specific to the Vision images that cannot be represented in the file formats normal image (overlay information, benchmarking, custom, etc. data info). If you are save the string flattened in a file and expects to open as a normal JPG file, it is unlikely to work properly. The only way that it would be guaranteed to work is if you switch to the corresponding VI "unflatten chain. I don't know why it works in 32-bit mode, but it sounds like a lucky fluke.

  For your use case, you probably want to use the VI "IMAQ write the string. This does not give a result string that is identical to the specified file format.

• Compress the Images on the report

  Hello

  I am currently running a report that requires a ton of pictures.

  The size of the photo files varies between 4 and 10 MB per photo.

  When I generate one. PDF of my DIadem report the size of the file is big enough.  Is there anyway to compress the image similar to "Compress pictures" feature in excel?

  Thank you

  Hi Tim,.

  You can set compression JPEG and PDF resolution with program variables by setting them in a Script of DIAdem. You can set the program variables are discussed in these help documents:

• Best practices for the compression of the image in dps

  Hello! I read up on best practices for the compression of the image in dps and I read the asset from the source of panoramas, sequences of images, Pan and zoom images and audio skins is resampled not downloading. You will need to resize them and compress them before deleting the in your article, because the dps do not do it for you. Hey can do!

  So Im also read as he active source of slideshows, scrolling images, and buttons ARE resampled as PNG images. Does this mean that DPS will compress for you when you build the article? Does this say I shouldn't worth going bother to resize these images at all? I can just pop in 300 DPI files 15 MB used in the print magazine and dps will compress their construction article - and this will have no effect on the size of the file?

  And this is also the case with static background images?

  
  

  Thanks for your help!

  All images are automatically resampled to based on the size of the folio you do. You can put in any image resolution you want, it's not serious.

• Tiara (image) to the database file

  Hi all

  Recently, we found a problem with our application. Instead export the report to a network drive images, we save it in a database.

  So far, we have saved on a network without any problems. We are able to access our database and insert some text values in the application, but now we need to save files (images). This is where things are more complicated. Tiara features a textStream object, but not an inputstream that allows to read a byte array...

  Then, someone had a problem like this and found a solution? I found a few samples of something similar on the site of NOR, but they are all for labview...

  Any help is greatly appreciated,

• How much space will be an average image of the system take?

  I am planning to buy an external hard drive, so I store my backup system on it my computer failure. I just want to know how much will be an image of the system average resumes if you have a few programs with a value of approximately 20 GB.

  PB

  If you make an overall picture of the partition to the OS, it will take the same amount as the OS partition before compression.  Compression can reduce the size of ~ 25%

  For example
  Your operating system partition is 40 GB image would be ~ 30 concerts.

• organize images in the form of grid

  Hello

  How to organize images in the form of grid as a form of the matrix 2 x 2.

  any solution please.

  Kind regards

  Hari

  Thinnker,

  I'm not sure I understand what you're trying to do, but I have modified what I could from your code to make it work without changing the structure so that it become unrecognizable to you.

  I've replaced your IMAQ control with control of 2D image, because I have not installed IMAQ. This VI works as expected and load your file of jpg files in the table of the photo.

  If you work with IMAQ, note that your images will be loaded all into the same reference IMAQ because you create only one (called untitled), so with each image you load, you override the earlier. You must move the IMAQ Create function in the loop For and generate a new reference for each image you want to load (each requires a unique string for its name).

  You can retrieve the image encoded base64 string object, but will not receive the path of the file (The API Reference). To display the image, you can use a URI of the data with a tag.

• Problem with image extract the content and the tile at the same time show on ListField

  My application is Application News get JSON webservice to appear on ListField.

  On each line in the list, it will show you the image thumbnail, title and Teaser as below.

  _______________________________________

  |                |                       Title

  |   Thumb  |_______________________________

  |_______  |                       Teaser

  First of all, I have to get JSON that contains the url of the thumbnail image, title and Teaser.

  
  

  I managed to view the title and Teaser, but the thumbnail is not. When I Fetch image with the url of the thumbnail image, it returns only bitmap = null for me.

  My method is first call httpdispatcher to get the thumbnail image, title and Teaser and then wait and call another httpdispatcher to retrieve the url of the image thumbnail, then added to listfield.

  Here is my code

  Class helloScreen{

  The point here is that I have JSON and get the url of the thumbnail to fetch before add to listfield. The image should be ready in bitmap_temp but it still get null.

  UiApplication.getUiApplication().invokeAndWait(new Runnable() {

  Hello

  I was unable to find a post that details how to retrieve the bytes of the image of an image (given the path to the file of the image on the device).  Basically, using the FilePicker, I'm able to get the path of an image chosen by the user:

  There you go:

  Pass just your file as method parameter name.

   public static byte[] getBytesFromFile(String filename) throws IOException {
          FileConnection fconn = null;
          InputStream is = null;

  The problem is that the Torch 9800 Simulator choke on it.  "I get randomly ' JVM error 104: Eception: OutOfMemoryError.  I say randomly because sometimes after taking pictures of 3-5 successfully, and sometimes it pours on the first attempt to photograph.  I've cleaned many times Simulator.

  The same code works perfectly in 5.0 simulators (9550, 9530).  I can take pictures until I'm blue in the face without an exception OutOfMemoryError.

  I saw this method of capture an image (using the MMAPI implementation)...

  Take a photo in an application device of BlackBerry - Multimedia - Development Guide - BlackBerry Java...

  .. .but I want the user to be able to have the user of the native camera of experience.  Therefore, listen to JPG file was added.  Is it still valid in 6.0?  It is, of course, to some extent, or my photo app would not work.  Is there something with log being numbered differently?

  The FileSystemJournalListener is not the problem.

  The exception OutOfMemoryError seems to be related sending images of native Java coding to JavaScript.

  Only one problem in 6.0.
