How to display a bmp in labview?

Hi, all
I want to display bmp in labview. I use function: draw image from File in OpenG library.
But i report error because this is Unsupported image depth. My bmp is 16 bit depth.
Should i conver it to other supported bit depth? there are so many files. Anyone can tell
me how to resolve this problem? Thanks very much.
attached my bmp file.

For vision you will need a seperate license.
Here's a VI that will read 16 bit images. However the colors for 16 bit color are ambigious. So you will need to tinker with the colors.

How to display scope plot in Labview GUI?

I am trying to figure out how to show TDS8000 scope output plot in LV GUI(?)
This maybe a two fold question.
1. I suppose it may be necessary to adjust the scope scale with appropriate level so that the plot will show enough details of information. (e.g., finding Max and Min points)
2. how to display scope plot in LV GUI?
It would be a great help if anyone can share an example VI.
Thanks,

Hi jjlee,
It shouldn't be that difficult of a task. Most instrument drivers have
a simple initialize VI, and then some type of waveform measurement VI.
You would connect these two VIs and then take the output from the
waveform measurement (may be waveform acquire or something like that)
to a graph or chart (depending on if you're outside of inside of a
loop). That should be all you need to do for the simplest form of this
application. You would, of course, want to handle errors and close the
connection to the device when you're done collecting the data.
Hope this is of some help,

Does anyone know how to display (in LabVIEW) the memory use during execution of an image and data acquisition VI to predict when it is time to cease the acquisition to prevent the program crashing?

Does anyone know how to display (in LabVIEW) the memory use during execution of an image and data acquisition VI to predict when it is time to cease the acquisition to prevent the program crashing?
I am acquiring images and data to a buffer on the edge of the while loop, and am finding that the crashing of the program is unpredictable, but almost always due to a memory saturation when the buffers gets too big.
I have attached the VI.
Thanks for the help

Take a look at this document that discusses how to monitor IMAQ memory usage:

I want to use Get Panel Image in Labview 5.0.1 and need details on how to save the BMP data generated

I am trying to generate an application that saves a copy of its front panel on completion. This is easy to do using an invoke node with Print VI to HTML but this does not work in an .exe format. I have seen elsewhere that you have to use the Get Panel Image method, but no details are supplied in LV 5.0.1 documentation of how to use the "image" data (1-D Unsigned Byte array) that is generated. I want to save this in a format that can then be read as a bitmap in any standard graphics package. Any assistance?

Hi,
If you'd upgrade to LV5.1 or 6 you could use the 'standard' vi's for this.
You need a VI called "Write BMP File.vi". It's not shipped with LV5.0.1.
This vi only uses 3 subVI's, so perhaps someone at NI can convert it and
send it to you (sorry, I won't, it's copywrited).
If you cannot get this VI anywhere, you'll need to figure out the BMP file
format yourself. It's not too complicated, but still could take some days.
Perhaps someone figured it out before LV5.1 was released.
Regards,
Wiebe.

How to display URL images and URL link (html) from Smartforms?

Hi Gurus,
I'm having difficulty on how to display targeted URL images and URL link from the smartforms, after i sending it out as html mail. The mail i sent just can be preview as a plain text, which can't execute the html code that i put inside the smartforms itself. I follow a few step from this very useful blog.. Hopefully, you guys can give me some solutions or ideas on this.

1- put your images in a directory under the web app directory. Example: app/images/
2- in your jsp, use: String file = application.getRealPath("/images/"); to get the images directory. See http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/servlet/ServletContext.html#getRealPath(java.lang.String)
3- it's not the right forum to post this kind of question. Post them in the JSP/Servlet JSTL forum instead

How to display PSA screen capture on Front Panel

Any one know how to display screen capture of PSA series specturm analyzer on front panel. I can save the JPEG file in the C drive, but I can't display on the front pannel. Please see my labview code.

Do you actually need to save the front panel image? Or do you want to save a graph of the signal (spectrum) that you acquired? If the latter will do the trick, you can simply read the waveform over GPIB (or whichever means you control the analyzer) into an array that is plotted to a waveform graph in LabVIEW. You then save the image of the waveform graph as an image.
Since you have all the data, you can even save the data which can be viewed later (and not only by LabVIEW).

How to display every other images in image indicator

Hi All,
I am using IMAQ to grab and save high freq and high resolution images. I have an image indicator directly from "Image Grab Acquire". So, the image indicator is displaying every single images at a very high frequency too. We have to display frames, but not necessarily every single one (enough so the operator can see what's going on). So, I am wondering how I can display, say every other images (such as all odd/even number of images), or jump over two and display the third?
Any help will be appreciated!
Thanks!
Wenlong

Here are some general comments.
Image acquisition is "a horse of a different color" -- unlike many other I/O devices, the memory that holds the data (here called the "buffer") is managed by the driver, and isn't directly available to LabVIEW.
I'm guessing that you are using NI Video hardware, as you are using IMAQ functions (I've only used IMAQdx). Is this true? What camera are you using?
The IMAQ Extract Buffer (probably) "clocks" itself to the camera (I say "probably" because I don't know the hardware you are using). This means that the While loop containing it will run at the frame rate of the camera (hence you can easily calculate the frame rate, as your code shows).
This looks like an NI Demo routine, so I'm guessing that you don't have a lot of experience with Vision processing. If you've got a lot of other LabVIEW experience, you should be able to make the leap to vision, once you get the idea of how buffers work. Unfortunately, there's not as much in the way of tutorials and white papers on Vision as on other LabVIEW topics.
So to your question -- how to display every Nth image. Here's the key loop (which is lifted directly from your code):
As menioned above, this routine is "clocked" by the Extract Buffer function. What you do to display every N'th image is to put the Image control inside something like a Case statement that "fires" every Nth time.
Here's an "Nth" version of the above loop (some details omitted) --
We still drive the loop filling every buffer with a frame. But we then use the Integer Divide function to select the Nth image (those that have a remainder of 0 when i is divided by Nth) and wire the "image" line (it doesn't really hold an image) to the "Image" control, with the other case being "Default" (so all other valeus go there) and with nothing inside. Thus every Nth time through this loop, the output of Extract Buffer is wire to an Image (and displayed), the other N-1 times the wire goes nowhere.

How to display two waveforms in one waveform chart?

hellow!anyone can tell me how to display two waveform together in one waveform chart? thanks!

Hello,
An easy way to tell how to make multi-plot charts and graphs is to hold your mouse over the chart/graph terminal on the block diagram and make sure Context Help (Help >> Show Context Help) is enabled. This screen will tell you how to connect the indicator for a multiple-plot display.
You might want to take a look at my attached screenshots of a working multi-plot chart.
Hope this helps!

Idoc-xi-file scenario. how to display file in html format

I am not sure whether this is a valid question.........but want to confirm as it was asked by somebody
In idoc-xi-file scenario....... how to display file in html format ??
Thanks in advance
Kumar

Hi Vijayakumar,
Thanks for your reply !! You mean to say I got to use XSLT mapping and also .htm and .html extension together to produce the html file ?? or it is sufficient to use any one of them to produce the html file ??
