I am looking to use Labview to capture an image and store it.
I also want to tag other data onto the image so that I can place the image in context i.e. orientation and positioning. Can someone point me in the right direction?
Pinki2k;
You may want to take a look at IMAQ, which can be used along with LabVIEW for what you want. Another alternative may be IVision from HYtek Automation.
You will get better answers if you post this question in the Vision forum.

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

When I am trying to package my artwork in Adobe Illustrator CC, it is not capturing my images and fonts. How do I make sure my linked photos and fonts are captured?
Not all fonts can be packaged depending on their licensing. Some fonts are set to not allow packaging. For those you would have to manually locate them on your computer and add them to the folder where the packaging occurred.
For the images have you checked the "copy links" option? -

hi guys;
kindly, can any one tell me : is it possible to use Labview installed on desktop pc to show up statistically the main performance key features between mutlicore systems and single core systems but with (two versions, embedded and general purpose CPU) . in other words: I'm trying to resemble embedded cpu with general purpose CPU so that i can only work on Desktop pc than say that the obtained results are the same for embedded multicore CPU.
to get things more clear:...embedded multicore processors are now hitting the embedded market segments such as (small and portable devices with internet, multimedia and wimax tech. enabled that take advantage of recent multicore tech.).
general-puroses Multicore processors: like desktop and servers based processors,
according to what 've read, Intel is producing same processor model but with different applications : (embedded and general-purposes applications)Hello,
Please look at this page which shows a new feature in LabVIEW 2009, but particularly interesting is the video which shows the performance benefits on a PC platform of single core VS multicore.
LabVIEW doesn't have any ability to emulate a multi-core embedded processor (unless its an intel x86 processor that labVIEW supports!) so to discover the performance benefits of embedded multicore processors, you would need an external hardware board and devise a test in which labVIEW can measure the timing via an external pin toggled by a program running on the embedded processor that could utilise multiple cores (there may be other ways but this is the way that comes to my mind).
I hope this helps you!

How to capture an image and save it using action script
Hello,
I need to know if is posible to capture an image or a screen region and save it using action scrip.
Somebody know how to do it ??
Thanksyou can capture an image using the bitmapdata class and getPixel(). you can then save that to a bitmap using server-side code like php.

I have some question on "Use LabVIEW to Control two DSP and RTDX"
I have some question when writing LabVIEW. I have DSP6711 and DSP6416, I use RTDX to send data to LabVIEW.
I write three programes for LabVIEW, one is RTDX for DSP6711, another is RTDX for DSP6416, and the final is RTDX for two DSPs.
The program of LabVIEW is workable when doing DSP6711 or doing DSP6416. But there is some problem when running DSP6711 and DSP6416 on LabVIEW at the same time.
How to tell the LabVIEW's tool of " RTDX read" to get the datas from different DSPWhat you want to do should be fairly straightward and a good way to learn labview.
First off, if you haven't already, I would download the drivers for the Keithley and Agilent instruments. I found the keithley drivers at the link below. You will need to find the labview drivers for the Agilent PS at their website. Drivers are the VI's you will use in your program to control the insturments.

If you open Labview and go to the help menu and click on Labview bookshelf there is alot of information on getting you started coding labview. This should get you started, if you have anymore questions just ask in this same thread and I am sure you will get all the help you need.

Use LabVIEW FPGA as a DAQ and detect peak
Hi everyone, need your help now.
I want to use Labview to encode a FPGA to achieve following function:
1.Acquire data as a DAQ from a Photodetector
2.then use peak detect VI to measure the peak information
3. some simple mathematical operations
is it possible for me to achive all these only using one FPGA? and is it OK to connect DAQ's output and the input of the peak detect VI?
thanks a lot. I am a beginner, so it confused me a lot.Hi
What is you hardware? cRIO? FlexRIO? And what your signal type? Anolog or digital?
You can refer to the help of Peak detect.vi to comfirm if the data (sigle point integer or integer array ) can be wired directly. I am afraid you can not wire the FPGA IO OUT directly to the Peak detect.vi, but you can create a array for the data and then use the peak detect.vi

Can i use labview to capture and process images from ip cameras connected to a switch.
Hi,
i have more then one ip cameras conneted in LAN by a switch. i have a PC conneted to same switch. is it possible to capture images from these ip cameras and process them(for example performing simple barcode scan or QR-code scan or OCR)? Which IP cameras will be supported?There is functionally no difference whether the camera is connected directly to the system or via a switch. Both should work the same. The only real requirement that you'd need to care about is whether the switch can pass multicast UDP traffic correctly (this is used for network discovery of IP cameras). Generally all unmanaged switches (probably what you are using) will treat multicast traffic identical to broadcast traffic, but some managed switches/routers may need to be configured to pass multicast.

Hi all,
I´m currently doing some measurements with a type T thermocouple. Currently I get 1 value every second and I can´t figure out how to get more measurement samples per second. Is the system the problem or Should I change some settings in LABVIEW?

Using SE friendly urls - Broken Images and other questions
Im trying to find a workaround for an issue caused when I create SE friendly URLS and i have a few questions too.
I am making www.mydomain.com/itemid=114
into www.mydomain.com/shirts/red/114
question, is keeping the 114 still in the url ok?
does it matter if its at the beginning or the end?
like the above or like this www.mydomain.com/114/shirts/red
and the biggest issue is - how do i work around the image references.
www.mydomain.com/itemid=114
on this page, i have an image named LOGO.jpg
and the reference is just i/logo.jpg which is relative to the page url and the real location is www.mydomain.com/i/logo.jpg
HOWEVER
when i use the SE friendly url, its looking for the image in the relative folder - (which is a fake folder of course)
www.mydomain.com/shirts/red/114
so on this page its looking for www.mydomain.com/shirts/red/i/logo.jpg
SO - my question is - how do I override this and force it to ignore the folders references in the url? I still need it to look for www.mydomain.com/i/logo.jpg. I do realize that I could of course reference the images using a full url ....
meaning instead of using i/logo.jpg i could use www.mydomain.com/i/logo.jpg
but i would rather not go this route since there are about 20 image references within the template. so if there is a better way to scoot around this I would love to know what it is.
Thanks in advance
SamI bet you are using a relative path for your css include
instead of a root path. So if you have the following in your
http://localhost/demo/index.cfm
<link href="../styles/main.css" rel="stylesheet"
type="text/css" />
then it will look in the next folder up for a folder called
styles with a file called main.css
If you have the same line of code in
http://localhost/demo/index.cfm/about-our-company
then it will look for a folder in the root called demo with a
folder in called index.cfm with a folder in called styles with a
file in called main.css.
To solve this you need to reference your style sheet as
follows:-
<link href="/styles/main.css" rel="stylesheet"
type="text/css" />
Notice how the href begins with a forward slash (/) this
means to always access it from the webroot. You will need to do
this for all your internal links as well because they will not
work, this means links and image references the works.

Captured & imported image, and driver package not going to DP
I have an image I've imported and even though I've selected "Distribute Content" manually it does not go to DP. I checked everything I could think of (making sure DP was set to service the boundary group, etc.), but it still won't go.
In status, it says "in process".
Question - do I need image/properties/package share settings "copy the content in this package to a package share on distribution points" selected to enable this image to be sent to the DP?
Under Distribution Settings - do I need to select "Distribute the content for this package to a preferred DP..." and any recommendations on if this should be sent to Automatically, Download only changes, or Manual?
Similarly, I also noticed my Driver Package had also not been sent to the DP, so my question applies to that as well. After creation, do these settings need to be selected?
Thank you
NathanHi,
The reason why this happens is a combination of the following two reasons:
- You enabled for prestaged content in the distribution point.
- Go to the properties of the image, on the "Distribution Settings" tab the radio button is set to "Manually copy this content to the distribution point".
Enabling the prestaging option on a DP will tell the DP to not receive content automatically. It is waiting until an administrator copied *.pkgx files manually to it and registers them using extractcontent.exe. That might be useful for DPs at the end of very
small WAN links.

How do i open and control other programs using labview?
I'm presently trying to use labview to try to open and operate another program,but having much difficulty.The external program i'm using is called the Foundation program.
This Foundation program will use VHDL programming to create a virtual chip and then synthesising it.This program will then simulate the output of this VHDL program to verify that it is working as desired.Then the last stage is to download the whole VHDL program into a FPGA chip using a xilinx cable.
All this need to be done using a labview program - to open the Foundation program and then extract the saved file and then to execute the download command to cause the VHDL program to be downloaded onto the FPGA chip.How do i go
about doing all this?What is the first step i must do.Also all this have to be done thru networking..looks like its too difficult..I really need help.
graysI haven't done VHDL so pardon my ignorance.
LabVIEW can call external DLL via "Call Library Function" or C programs via "Code Interface Node", both located in "Advanced" function.
If your program is a DOS program, use "System Exec.vi" found in "Communication" function. If you need to format your DOS command prior to sending it, use the "Format Into String" function in "String" function palette.
Lastly, if you're trying to extract data, assuming it is text, use "File I/O" functions. If the data is binary, use "File I/O -> Binary File VIs".
Hope that answers most of your questions.
