How to create an gray scale png image from intensitie​s values

Hi,
  I would like create a gray scale png image from set of intensities values which is saved in excel sheet . Is IMAQ tool necessary for this vi?
thanks & regards
Manoj

You posted in the feedback forum, which is not correct for your question. I am guessing you are talking about LabVIEW since you mention "vi".

The answer is NO. Plain LabVIEW is sufficient.
LabVIEW Champion . Do more with less code and in less time .

  • How to create a 16-bit grayscale image from matrix of values

    Hello all,
    I'm having a problem converting a series of measurements into a specific image. I have a matrix of nxm dimensions (n and m variable), which contains measurement data. My intention is to transform this matrix into an image to be analyzed later on by an external software. The trick, however, is that the image has to be in 16-bit grayscale format: in grayscale for doing the image processing, and 16 bits to make sure that resolution is not hindered.
    I've been looking around the web and still haven't found a way of somehow mapping the measurement values I have in that matrix into pixels (16-bit grayscale ones, that is). I have access to the Full Development System version of LabView, but not other toolboxes.
    Does anyone have any suggestions?

    Hi everyone,
    I've managed to get it to work thanks to some help from people on other forums. The key is to use the IMAQ driver, which gives the VIs necessary to create images on 16-bit grayscale (only supported nicely by PNG format apparently).
    The discussion on the other forum can be found here: http://stackoverflow.com/questions/11101420/structure-of-16-bit-grayscale-image-to-be-generated-in-c...

    How to create a contact sheet of images in CS5.  Different set up than older version I worked on before.

    Have I missed something that the Adobe Bridge Output Module didn’t seem to offer a printing option?  Tried the older plug-in which is what I was familiar with, but that seems to download all the plug ins, not just contact sheets. Do I have to download the whole shebang?

    Hi guys,
    Is there an example anywhere for Labview 8.6 for loading a picture control with png image from the web?

    Hi lavalava,
    here you find a note on how to load pictures from the internet. After grabbing the data you could save them to a file, load the file with the picture file functions and then convert it into the image datatype to feed a picture indicator with the data...

    Each time I use Photodownloader it downloads all images , also those that were downloaded preveously
    How can I set photodownloader?

    I share my card with my wife and she likes to download our images also on her PC, so erasing all images is not an option.

    Don’t you format the card in the camera after each download? That will wipe all images and prepare the card for a fresh shoot.

    Hi Mahendra,
    Thank you so much for your reply.
    So you mean to say that it all depends upon the Sourcing Rule and ASL based upon that system would automatically create a Blanket Release or If its Automatic Release/Review then we have to manually create release through autocreate.
    The reason why i am asking this query is now when i tested it, system is automatically creating release and starngely there is no Sourcing Rule and ASL has been defined.
    But we are looking for a Manual Release through autocreate window.
    It would be great if you could please suggest.
    Regards,
    JohnJohn,
    When you say system is automatically creating release..as far as i know...it should be referencing a PO..correct...in the releases window..
    can you pull that up..and see if you can get any clue..bcz that PO would BPA...
    Also I am not that much into Iproc...I don't know...whether Iproc has some other setups

  • HT5517 How can have full picture using mirrored image from iPad

    How can have full picture using mirrored image from iPad on my Apple TV airplay

    Welcome to the Apple Community.
    Mirroring won't fill the TV screen. The iPad has an aspect ratio of 4:3 and the iPhone 4S or prior an aspect ratio of 3:2, neither of these will fit exactly into a TV screen which as an aspect ratio of 16:9. The Apple TV will not zoom the mirrored image, because it may well cut off information which is situated at the top or bottom of the screen.
    You may wish to try each of the settings in ‘Settings > Audio & Video > Adjust for AirPlay overscan’ for the best setting that suits you.

  • Problem loading images from a return value of a function

    hello, I write because I uin problem in loading images from a return value of a function.
    I created a database with a field "image" of type string, where I put the physical address of the image. I have written like this: {__DIR__ }foto.jpg
    Place the code, so you understand better
    function imageViewImage(): javafx.scene.image.Image {
    connetti();
    lass.forName(driverName);
    con = DriverManager.getConnection(url,user,"");
    stmt = con.createStatement();

    JOptionPane.showMessageDialog(null, result);
    var imagez = Image{
    url:"{result}";
    return imagez;
    The image is in the source code package
    First I connect to the database, run the query and I take the contents of the image.
    Can anyone help me?
    Is right to put in the database {__DIR__} foto.jpg or do I put only foto.jpg?

    Hello unkus_nob,
    I would rather suggest you to save only filename of that image like "foto.jpg" in database. And just concat it with the String variable containing "{__DIR__}".
    Actually the javafx compiler converts the {__DIR__} to the existing class directory path something like : "jar:file:/..../".
    var currentDir ="{__DIR__}";
    risultato = "{currentDir}{rs1.getString("immagine"})"; 
    var image = Image{
        url:risultato

  • How to Convert FLIR Gray Scale Image to a Temperatur​e Map in NI VBAI

    I have been working with a FLIR A315 Infra-Red camera and NI's VBAI software.  I need to determine the presence and continuity of a hot mastic foam that has been injected into the hollow bulb of a rubber weatherstrip seal in 4 adjacent locations that flow together inside the weatherstrip bulb to form a continuous foamed mastic plug.
    So far, I have been able to trigger image acquistions in VBAI from a FLIR IR camera by monitoring an Allen-Bradley PLC's status bit.   The communication with the FLIR A315 camera is via the IMAQdx GigE driver.  However, I haven't figured out how to detemine the temperatures from the gray scale images I receive from the FLIR camera.  I wonder if someone could give me some pointers on how to do this.
    I have attached some images below to illustrate what I am working with and how far I've gotten.
    iPhone_Photo.jpg - shows a photograph of the weatherstrip section that the FLIR IR camera is "looking" at.
    FLIR_IR_Monitor.jpg - a screen capture of a FLIR IR monitor utility that shows temperatures measured at a number of points and areas (showing it can be done)
    NI_VBAI.jpg - part of my VBAI 2010 project which shows the image I've acquired from the FLIR A315 IR Camera
    So, I am part of the way there, but so far have not found a way to map the gray scale image that VBAI is acquiring from the FLIR IR camera into a heat map from which I can determine temperatures - and would appreciate some help on how to do this.
    Kind regards,
    Nick

    Hello,
    Image provided by FLIR camera are unsigned 16bit.
    Depending on the FLIR temperature scale you selected (10mK or 100mK), you will have to divide by a 10 or 100 factor to get K values. Don't select radiometric output.
    So if your object is cold, the population of the histogram of your image will be on the left part of it and if the object is hot, the population of the histogram will be on the right part.
    If you want your temperature values in Celcius, just add 273,15 to the Kelvin Value.
    Then you can add a color palette in VBAI (FLIR iron is available)
    Hope this helps

  • Gray scale photos images are different but should be the same; help?

    I send a gray scale image from Lightroom (Edit with ...) and it opened CS4 photoshop.
    I made a blank document , 11x14".
    I used Windows/arrange/ tile to view the blank and the gray scale image. I tired various methods of bringing the gray scale image to the blank one (move tool, select all and move, copy and paste). Each time, I did this within seconds of each other (I made no changes to fill, opacity, and I used Normal). I brought the image in twice so I could print out the SAME image twice on the larger 11x14 at Sams club in order to use the Epson 7800 printer and not the old wet process on the Fugi machine. One image is darker(lighter) than the other every time. I even tried another image and I got two different exposures.
    I wonder if it it only happens with the grayscale images? Perhaps it is a problem coming from Lightroom 2.5?
    I did a three image 16x20 and I didn't notice the difference - partly because they were three differenct images in color. I will try two color images from the same file tomorrow.
    Any thoughts? I haven't found a possible setting problem that would have been applied between the operations.

    Paulo,
    Thanks. I was ready to believe the monitor idea but I still have some reservations.
    I don't doubt what you said about the pixels (sounds correct to me).
    Why?
    I tried another monitor and the images I attached also look like the top one is darker (vertically).
    Also, the same is true if I scrolled the images. It seems to me that I should see a difference as I slowly scroll the image vertically. I didn't see a difference.
    Read on please.
    At any rate (I long for a CRT - my 21" crapped out last year), I am using  two SAMSUNG screens, the
    one attached to the main computer is the Syncmaster T220 - a well rated
    monitor; as far as I knew , read and had friends who recommended them.
    The other I just tried is attached to the second computer a couple of feet away. It is the syncMaster T240HD. 
    So, if it is an LCD monitor problem, it is with both and the same
    company. I would think I would have read some bad reports about these
    LCDs?
    Also, wouldn't the color images also be different when presented the same way? (they aren't).
    However, I went back to the original T220 LCD display and moved an image in to a blank one as before, then did the control J to copy the layer, and the images we different again. But, I zoomed in more than usual and scrolled the images and they were lighter at the bottom of the screen and darker at the top of the screen!!!!!!
    That is good news and bad news! $$$$$$
    If it is the monitor problem, then both images should print as the same.????
    Secondly, the display (LCD) attached to the machine at Sams showed the same difference between the two images. AND, I recall that the display is also a Samsung (I will check that tomorrow).
    What a bunch of coincidences! I guess I have to search the web for some Samsung answers? and contact the company?
    I want to explore as much on my end as possible.
    Hunt and another suggested the Control-J to avoid the problem by copying the layer. That didn't work either.
    I suppose I could tweak one of the images after bringing them in but I don't know how (I clicked the layer and I wasn't able to do anything - like lighten that image).
    Again, thanks for the help. I think the question maybe answered.
    I will send the screen capture shortly.
