How to read and display a fits image into JPanel

Hi,I currently want to read a .fits file and display it in JPanel,have no idea how to achieve it.Any suggestions and source codes are appreciated.Thanks in advance!

fits stands for flexible image transport system,it defined only for astronomy image data.it is not normal image,I am afraid I can not use the way you said to read fits file.Anyway,thanks a lot.

How to read and display a signal from my a miccrontroller (MCB1700) onto labview connected via a CAN port on a PXI machine

How do you read and display a signal from my a miccrontroller (MCB1700) onto labview connected via a CAN port on a PXI machine?
I tried using a DAQ Assistant but the CAN port is not included as one of the supported physical channels even though all its drivers are upto date.
Please help..
Thanks.
Solved!
Go to Solution.

Attached herewith is a print screen of what is showing on MAX
The CAN ports are on NI PXI-8461
Hopefully that clarrifies something.

How to read and display a signal from my PIC Microcontroller onto Labview?

Hi,
I am doing a project on a Pulse Oximeter and i am trying to read and display the signal from my PIC Microcontroller on Labview? How do i go about doing it? I am using the PIC16F877 and also making use of the USART?
How do i implement and initialise the USART in PIC16? What are the steps to be taken, please guide me through the process? The link provides information regarding the USART connection, initialisting and stuff? Is it correct to use these codes in my program?Link: http://ww1.microchip.com/downloads/en/AppNotes/00774a.pdf
Also, i am using the RS232 serial interface to connect to the PC? The connector i am using is the DB9 Connector. Which template and VI can i use? Am i supposed to use the NI-DAQmx and VISA? Also, for my USART connection, i am using the MAX232 Driver which is applicable for my application as i am working with +5V. So far, i have been reading and trying out on Labview and the steps i have taken are:
1) Open a New VI and used the Instrument I/O(Read & Display) template?
2) How do i configure the Instrument I/O Assistant Express VI to read the info from my device connected to COM1?
3) I was reading the Labview Manual, 'Getting Started with Labview' and i was following the steps under Page 55, Communicating with an Instrument. Am i on the right track?
4) How do i check and make sure that the port settings of the I/O Assistant and my PIC Micro Match
Please help me out and guide me through the process. I am student at a polytechnic and i am very new to Labview and the software is used as a development tool for the project. I have a deadline to meet and i hope i can get a response as fast as possible. Your help will be kindly and greatly appreciated.

Getting Started with Labview.pdf ‏901 KB

Hi Ashwin,
It is a good idea to first be able to communicate with the microcontroller using some sort of serial communication software such as "HyperTerminal" or "Procomm", etc. Refer to MicroChip's recommendations on this.
Once that works, then you are ready to use LabView.
Here is a link which covers many aspects of serial communication. Link - click here
You probably received a development kit. They usually have a readily available interface. It's been a long time since I played with the PIC, but I seem to remember that you need to program the serial communication driver (as well as at least a bootloader) to get the serial communication going. The driver contains the necessary protocols so that you PC can have a machine conversation with the target (PIC).
It sounds like a fun & interesting project. Please avoid to have replies to your personal email. By having the answers posted to this thread, you will get much more support and advice.
Have fun,

Hi Ashwin,
I am not familiar with the PIC Microcontrollers, but I am assuming you mean that you have the microcontroller sending out serial data that you want to read on another computer with LabVIEW. Please let me know if this is incorrect.
What type of data is coming out of the serial port? Is it ASCII, or binary? The reason I ask this is that the serial communication in LabVIEW is done through a protocol called VISA, which uses ASCII data to send and receive. You can later convert this data into whatever form you need, but this is what it is designed to read and write.
You can check the settings such as baud rate and data bits in a configuration utility called Measurement and Automation Explorer, or MAX. When you open up the MAX interface, you can expand the Devices and Interfaces entry on the left, and then expand the Ports entry to see your serial port. When you highlight this port, select the Port Settings tab at the bottom of the window, and you can see what the current settings are, and change them if you need to. You can also set these parameters in LabVIEW using the VISA Configure Serial Port VI.
You can also test communication in MAX by right clicking on the correct port and choosing Open VISA Session. Then choose the Basic I/O light blue tab, and then go to the Read tab. When you click execute, it should read in what is coming from the serial port. This will allow you to verify that the correct information is coming in before even trying to acquire the data in the LabVIEW environment.
In LabVIEW, the best resource to use the Basic Serial Write and Read example program that ships with LabVIEW. By examining the block diagram of this program, you will be able to see the basic programming flow of serial communication in LabVIEW.
I hope this information was helpful! Please let us know if there's anything else we can help with.

You need to pass your filename String as a parameter to your functionality. It depends how you're currently set up though. We can't really see the top of your call so it's difficult to determine what you are calling and we don't really know from where you're calling either.
If you're running standalone, then on launch of the application, you can feed in a file name as an argument that you can read in in String args[] in the main function and pass down to your XML splitter.
If you're a method in a class that's part of a bigger pile, you can feed the file name as a String to the method from wherever you call from if it makes sense architecturally.
You might also want to pass down a File object if that makes sense in your current code (i.e. if you're using your file for other purposes prior to the split, to avoid recreating closing/opening for no reason).
Depends what you're trying to do. If I put together a piece like this, I would probably create an <yourcurrentrootpackage>.xml.splitter package.
Also, on a side note, you're problem isn't really reading and writing XML in java, but seems more to be making your functionality generic so that any XML file can be split with your code.

How to read and display table data entries from ERP in CRM

Hello experts,
I am new to CRM. I need to read data base entries from ERP in CRM system. What would be the best way to do . The table is a standard SAP table with a custom include (several customer fields). Calling a web service would be the best way..? or is there any other way that I can do it too.
Also, to display these entries what would be the best tool? Should I built my own transaction/report to do it?
Any advise or guidance would be a great kick start to learn the CRM development environment.

How to acces and display datas storaged in cache for a SUP 2.0 workflow?

HI to all.
I have an application with a item menu which obtains data thought a online request. the result is shown is a listview.
My problem is when my BlackBerry has no conection ( offline scenario). When I select the menu item, I obtain an error.
How to acces and display datas storaged in cache for my MBO? I have read that I can use getMessageValueCollection in custom.js to access to my datas but once I get the datas, How can associate those datas to a Listview like a online request?? Do i have to develop my own screen in html or how?
Thanks.

I'm not entirely clear on what you mean by "cache" in this context. I'm going to assume that what you are really referring to is the contents of the workflow message, so correct me if I'm wrong. There is, in later releases, the ability to set an device-side request cache time so that if you issue an online request it'll store the results in an on-device cache and if you subsequently reissue the same online request with the same parameter values within that timeout period it'll get the data from the cache rather than going to the server, but my gut instinct is that this is not what you are referring to.
To access the data in the workflow message, you are correct, you would call getMessageValueCollection(). It will return an object hierarchy with objects defined in WorkflowMessage.js. Note that if your online request fails, the data won't magically appear in your workflow message.
To use the data in the workflow message to update a listview, feel free to examine the code in the listview widgets and in API.js. You can also create a custom listview as follows:
function customBeforeNavigateForward(screenKey, destScreenKey) {
     // In this example, we only want to replace the listview on the "My Approvals" screen
     if (destScreenKey == 'My_Approvals'){
          // First, we get the MessageValueCollection that we are currently operating on
          var message = getCurrentMessageValueCollection();
          // Next, we'll get the list MessageValue from that MessageValueCollection
          var itemList = message.getData("LeaveApprovalItem3");
          // Because its a list, the Value of the MessageValue will be an array
          var items = itemList.getValue();
          // Figure out how many items are in the list
          var numOfItems = items.length;
          // Iterate through the results and build our list
          var i = 0;
          var htmlOutput = '<div><ul data-role="listview" data-theme="k" data-filter="true">';
          var firstChar = '';
          while ( i < numOfItems ){
               // Get the current item. This will be a MessageValueCollection.
               var currItem= items<i>;
               // Get the properties of the current item.
               var owner = currItem.getData("LeaveApprovalItem_owner_attribKey").getValue();
               var type = currItem.getData("LeaveApprovalItem_itemType_attribKey").getValue();
               var status = currItem.getData("LeaveApprovalItem_itemStatus_attribKey").getValue();
               var startDate = currItem.getData("LeaveApprovalItem_startDate_attribKey").getValue();
               var endDate = currItem.getData("LeaveApprovalItem_endDate_attribKey").getValue();
               // Format the data in a specific presentation
               var formatStartDate = Date.parse(startDate).toString('MMM/d/yyyy');
               var formatEndDate = Date.parse(endDate).toString('MMM/d/yyyy');
               // Decide which thumbnail image to use
               var imageToUse = ''
                    if (status == 'Pending'){

How to Generate and Display SVG Graphics in ABAP

Hi everybody,
I tried to complete the Tutorial "How to Generate and Display SVG Graphics in ABAP, Part 1" by Siarhei Ulasenka (https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/ad83a990-0201-0010-d680-a189f8bc20fa).
Unfortunately when I tried the example to display an SVG Drawing in an ABAP Report I get the error message "Es ist ein Laufzeitfehler aufgetreten, ungültiges Zeichen" (english should be something like "Runtime Error, unkown character"). But it works when I open the svgfile in a new IE Window (parameter in_place from cl_gui_html_viewer->show_url). Also when I open a svg file from the local disc it works fine.
The code:
    CALL METHOD html_control->load_data
      EXPORTING
        url            = 'chart.svg'
        type         = 'image'
        subtype    = 'svg+xml'
      CHANGING
        data_table = lt_svg
      EXCEPTIONS
        OTHERS     = 1.
    CALL METHOD html_control->show_url
      EXPORTING
        url        = 'chart.svg'
        in_place   = 'X'
      EXCEPTIONS
        cntl_error = 1.
Has anyone a solution? Thanks in advance for your help!

Does Aperture read and display XMP data generated by LR?

Does anyone know if Aperture reads and displays XMP data generated by LR? I am not interested particularly in keywords.

Thanks for the quick reply, William.
I would suggest to David Schloss and AUPN that this would be a feature worth supporting. Although, hopefully both new software and improving skills in using them make me less concerned about preserving a static conversion or interpretation of an image, I think that whatever software we use to read/exchange keywords and other IPTC data is a constant.

Simultaneously trigger and display two camera images with two frame grabbers

When I try to simultaneously trigger and display two camera images, each with their own frame grabbers, Labview is only able to display one of the images at a time.
My hardware:
Two Sony XC-EU50 cameras (not in sync with each other)
NI-1410
NI-1405
My Software:
Windows XP and Labview 7.1 with IMAQ
I connect each camera to its own frame grabber. Both frame grabbers are in the same computer. I input a trigger into each frame grabber. Both trigger signals are identical. Trigger rate is only 0.2 Hz.
I want to display and save both images at the same time. The program i put together only displays one image at a time. The image that is displayed alternates from one camera to the other.
Please help with any suggestions.
Thanks.

Without having triggered two cameras connected to two NI boards with LabVIEW yet: This shouldn't be a limitation in LabVIEW.
Updating two Image Display Indicators in one run of a while loop definitely works properly, so this cannot be the reason for the problem.
Your code uses the IMAQ Snap.vi. This VI is not reentrant, so the both instances of this VI on your block diagram cannot execute at the same time.
I could not find an appropriate example matching your scenario exactly. (Maybe someone else knows better?)
I recommend to have a look at the examples in the "IMAQ Signal IO.llb" and do some copy and paste to get a VI that satisfies your requirements.
The "Grab with two boards.VI" illustrates how to acquire images without using the not-reentrant "IMAQ Snap.VI".
Hope this helps, Guenter
P.S.: Do you know NI's Vision Forum? http://forums.ni.com/ni/board?board.id=200

How to read 32 bit depth .bmp image

How to read 32 bit depth .bmp image using LabVIEW?

Go to Solution.

A "standard" image, by which I mean an image type most typically encountered, stores image data in RGB format with 8 bits per colour, making them 24-bit images (24bbp - bits per pixel). A 32-bit image normally includes an additional 8 bits for the alpha channel, but in BMP files this format is complex (see wiki article), and it appears the LabVIEW Read BMP function does not support it.
Do you have the IMAQ toolkit? I can't test the theory, but perhaps the IMAQ functions for reading image files are more advanced and can read your images?
