IMAQ FFT destination image, help!

Hello,
I am new to using LabVIEW so please bear with me!
I am reading/working my way through the IMAQ user manual for LabVIEW and I am trying to get IMAQ FFT working. But I have trouble finding the VI that the destination image of IMAQ FFT VI should be connected to. At the second it gives me an error when I try and run the program.
At the second I am really struggling to find the correct VI
Also I am little unclear what the destination image is for, does the image need to be saved?
Many thanks,
Jack

Hi,
For IMAQ FFT Destination Image should be connected and must be complex:

Error -1074396077 (IMAQ Vision: Incompatible image type) after running IMAQ Mask

I am attempting to process color picture of pellet. I want to exclude any particle that touches the edges of the color images. I created mask from original image and used this mask on the original color image to retain only the color particles that don't touch the boundary. The error occured when I ran the IMAQ Mask. The error message is “Error -1074396077 (IMAQ Vision: Incompatible image type)”. How can I fix it ?
I have picture and program as attached.

Hi XuanThuy,
The IMAQ Cast function is part of the Vision Development Module (VDM), under the Image Management Palette, as indicated by this document: http://zone.ni.com/reference/en-XX/help/370281P-01/imaqvision/imaq_cast_image/. If you can't locate it and you indeed have the VDM, there may be an issue with the installation of this module. A similar issue has been encountered and resolved in this forum post: http://forums.ni.com/t5/Machine-Vision/can-t-find-IMAQ-cast-image-vi/td-p/340157. What version of the vision software are you using?

IMAQ resample invalid image type

Hi,
I am rewriting an old non-versatile version of a VI. I don't have much experience but I have the old VI as sort of a template for what I need to do. It's weird but although I try to do things exactly the same way, they don't work.
I acquire a high resolution image from the camera (IMAQ Acquire) which is too big (1280x1024). I want to resample (IMAQ Resample) it to 256x320px.
I get the error message: Error -1074396080 occurred at IMAQ Resample Invalid image type.
The probe I put in to read the Image Src shows the image correctly and tells me it is an unsigned 16 bit image. This should be a valid image type, right?
Dennis
P.S. I use LabView 2009

No, not right. IMAQ Resample doesn't support U16 type (at least up to VDM2011). Refer to Help.
Convert your image to I16 (if possible) prior to resampling.

So your data is stored in XML. So what? You haven't asked a question about the XML or how to format it or how to access it. You asked a question that had nothing to do with XML at all. It's as if you said "My data is stored on a Windows computer so I will call Microsoft's support line to ask them this question."
And I can't even suggest a suitable forum because a "text area" could be an AWT component or an HTML component. But I do suggest you ask in the right place.

How to replace string with image( Say Emoticons )??

Hello Friends !!
I am working on chat messenger and want some help in "How to access Emoticons when somebody typed :), ;), :)) and many more strings.....?"
Is there any sample code to do that job or any function to perform such task??
Thanks in Advance....

use event listener... found match, load image instead of text on the fly.

IMAQ clipboard to image is slow

I programmatically make print screen commands, but conversion with the IMAQ function "clipboard to image" takes too long, 580 ms each time to be precise. More than half a second, and this on P4 2Ghz with 1 GB of RIMM, 1280*1024 pixels true color.
Is there a way to get the screendump in an RGB array maybe by calling user32.dll directly?
I need the screendump as an IMAQ image or 2D-array.
Thanks in advance,
Manu.

Andrew,
I have put together a small VI that should accomplish what you are after. I am attaching both the VI and a sample image that I used to test the code. Before running the VI, be sure to copy an image to your clipboard. The 3 2D array indicators on the front panel should correspond to the red, green, and blue components of each pixel in the original image.
Respectfully,

String to image field..

Hello all,
     shortly,   this is what i need:
     does anyone have an idea how to show string in an image field????
     now for the long story..:
     I have a table, that all cells are image fields.
     I send to some of them a xstring of a picture, and they are showing me the pictures (works fine).
     Now, i've got a demeand -
          if i have an indicator - i need to put this thing:
          "date: xx/xx/xxxx time xx:xx"
          this date and time can be changed every run.
     I though to make something like that:
          data: lv_string type string.
          lv_string = 'date 22/12/2012'
     then convert it to XSTRING with the fm 'scms_string_to_xstring'.
     but even then - when i send this xstring, the image field won't show the text. Actually it won't show anything.
     does anyone have an idea how to show string in an image field????

Um ...
... maybe.
I remember a custom solution from John Brinkman to continue text entries in the text field when the current field is full.
http://blogs.adobe.com/formfeed/2009/04/field_tab_on_full.html
This solution will propably work in a table too, but it's not a 5 minutes job to be realized.

IMAQ Vision - Writing Image Files: File Format

Hi,
I want to save some images in LabView 5.1.1 - IMAQ Vision 2.2.1 acquired by
a camera. Several file formats are supported:
BMP, JPEG, PNG and TIFF
For me the PNG format seems to the most attractive one as it provides
lossy-less compression and platform independentness. But, in the manual
there is a comment which I don't understand: It says that the PNG format is
not recommend for precise gauging or inspection measurements - and that is
exactly what I want to do.
I always thought that once an image file is loaded into LabView there is no
difference regarding to the file format the images were saved in. Can anyone
explain me, what the problem of the PNG format is? Which format can you
recommend for preci
se gauging instead (BMP?)?
Thanks,
Gerd Simons

one correction:
I use IMAQ Vision 5.0 and NI-IMAQ 2.2.1.

Working with Coreco, I get error 1074396072: imaq morphlogy invalid image border

the morphology gets input from threshold, which send o.k in error out. I work with Coreco, which I heard has some problems in defining the camera type or something

The morphology function requires some blank space at the edges of the image, which is called a border. You can set the size of the border when you create the image buffer, and you can adjust the size of the border using IMAQ ImageBorderSize.

IMAQ Error in Image Acquiring Loop

Hey,
I've been trying to develop a control for a USB camera that needs to take many images per run. I'm using the IMAQ-USB commands. The problem I'm getting is that after about 180 images I get the following error:
-1074396030
There are too many classification sessions open. You must close a session before you can open another one.
After I get this once, I continue to receive the error any time I try to use the program untill I unplug and replug the power to the camera.
The camera I'm running is a FLIR IR camera, Labview version 8.5 on windows 7.
If you guys have any idea whats causing this or how to fix it I'm all ears.
I've attached the program below.

Use shift registers on all your references, and use grab instead of snap. I don't have older version installed, so I cannot test this further. What camera model from FLIR are you using?

Converting string to image

hi all
i m facing a problem while converting a string in to an image.
Here is my code......
String s=new String(" Report ");
byte []raw=s.getBytes();
Image image = Image.createImage(raw, 0, raw.length);
but it is not creating an image....
but if we use the returning byte[] of the getSnapshot() method then it will create an image......why this happens...
how can i covert my string into an image???????plz help
ritwik

I need to convert a string to an image, I went throuth the topics in Sun forums but it's still not crear!!!
Please give a sample code to solve the simple task:
convert the string to an image (no applet) off-screen so that this image can be downloaded later !
I try to do this (as advised by some one on this forum)
BufferedImage bi = new BufferedImage(100, 100, 1);
Graphics2D g = bi.createGraphics();
g.drawString("test", 80, 80);
ImageWriter iw = ImageIO.getImageWriter(imageReader R);
iw.setOutput(new FileImageOutputStream(File outputFile));
iw.write(bi);
but only first row works , the rest couses exeptions!!!

Error-1074396074 IMAQ vision: Incompatible imag size

Hi everybody,
I need your help because I have a big problem and I don`t understand why...... But I hope it is easy to resolve.
I searched but found nothing.
I have this kind of error
But I don`t understand because I have two software, the first works very well, So I just copy this code to put in the second software, just to record one video.
Everything it`s the same but with the second there is this error message.
this software works very, whitout problem.
And this software, you cansee it is the same code, doesn`t work
I can`t understand why really..... I try to change the format of the imaq, or use IMAQ cast imag, but whitout results.....
If someone can help me
Thanks a lot in advance

Hi!
It is strange that if you used the same code, one time it works and another time it doesnt. To be able to see good if there is an error it would be great if you could submit your VI. But first try to take a look at this KB: http://digital.ni.com/public.nsf/allkb/4FAC615B62919BA5C1256ED00046997A
This explains the error and I hope you will understand which steps to take as there are also other links inside this KB for more information. So please verify the KB mentioned above and the settings you are doing in your code.
Please let me know how the progress is going.
