Imaq image to word report

I have IMAQ image and I want to generate report ald place this image in table cell:
Can I do that without safing image on disk?

Hi,
I don't believe there is another way, because you have to specify the path to the file.
What you can do is to create programmatically and delete the file at the end of your program execution.

Problem sending Tab/Cluster control image to Word report.

I've set up an option for the user to send a control image to a Word report where they can decide to Print and/or save from Word (I've found the normal Print option too slow with the printer available). The Word document opens fine but I am loosing data from my indicators, without which there's not much point in printing!!
Is there a problem with Clusters, I have a chart and table on another page of the Tab in my main program and they come out fine.
I'm using LV8 with the Report toolkit and Word 2000
Thanks
Ian

This problem has been reported in previous posts on the LabVIEW forums. LabVIEW R&D is aware of the problem, and it should be fixed in a future LabVIEW version. For now, the only workaround I know of is to make extra space in your clusters so the controls are visible in the report. I know it's ugly, but it's the only thing I know that works (other than reverting back to LabVIEW 7.1).

Dynamic Images in PDF Report

Hi,
I want to create Badges from employee table (ID, NAME, JOB_TITLE, PHOTO). I downloaded and installed a demo application "USING DYNAMIC IMAGES IN PDF REPORT". It works fine with smale images < 20K. I'm getting the following error for images > 20K :
"ORA-06502: PL/SQL: numeric or value error: raw variable length too long"
it seems like a buffer problem.
could you pls help to solve this problem
Thanks,
Ribhi

Hi Carsten
That was exactly* I was looking for. Maybe I should Google more in German ;-)
The main problem was that I defined my image outside the first repeating group (that doesn't repeat, it's always just one object) - the first group is followed by 7 more.
Just like the "Name" (that's positioned outside the group in the document header), I positioned the image above the table representing the group.
Doing that, the "Name" is filled correctly, the Image only when the Output Format is Excel or HTML - not Word or PDF ... makes no sense but that's tje way it is.
After moving the image inside the group....it works great!
(One more thing...the image size is fixed to the image you use as "dummy". Is there any way to make that more flexible, because now some scaling happens...)???
@Trent: That was the way we initially did it, but when the size of the row exceeds 32K...you know what happens.. And even with a small image the 32K limit is hit easily
The way I use it now (very similar to Carsten's description) there is no limit....
Thank you all!

Using IMAQ Image controls in LabVIEW steps

Hi guys
So far, I was using TestStand 4.0 together with LabVIEW 8.5 and Vision Development Module 8.5 with no problems. Recently, I've updated to LV 8.6 and VDM 8.6. I've started to experience weird problems when using LabVIEW steps with inputs/outputs containing IMAQ Image controls. When I try to click on such a step in seq editor, or try to insert a new step into the sequence, the step initialization takes a very long time (tens of seconds) or freezes completely. I've also tried to upgrade TS to version 4.1, but no difference. Also, my colleague experiences very similar symptoms on the same software setup. The only difference is that on his machine, it takes only a few seconds when you click on the vision step. However, the steps not containing an IMAQ Image control behave normally, i.e. you can't experience any "initialization time" when clicking on them in the sequence.
To illustrate, I'm attaching a simple VI containing nothing more that a single IMAQ Image control. If you don't link it to the connector pane, the VI works fine when inserted as a TS step. If the IMAQ Image control is linked to the connector pane, TS freezes when inserting such a step.

Hello Vladimir,
Thank you for posting on the NI Discussion Forums. This was reported to R&D (#123249) for further investigation. The only workaround I can offer for now is to work with the VIs from version 8.5 of LabVIEW if they have vision controls linked to the connector pane. Thanks for the feedback!

Showing dynamic and unknown number of images in SSRS report

I am using SSRS 2008. I need to display an unknown number of unspecified images on the report.
Basically I have a webpage, where the user selects a specific ID (ex. 24) from a dropdown and then click "View Report".
The report should then display any images, associated with that ID. The only thing I know about the images, is the path to where the images are stored. The path is kept in a database, so I should be able to retrieve the path ok.
But then how do i get the report to display the images, when I do not know the name or number of images?
Please help.

Hi dukie4lif,
According to your description, you have a report to display images selected by users. Now your issue is, the users select a specific ID to get images, but you only have the path of images stored in your database. Is my understanding correct?
For your requirement, if the users want to get images by selecting a specific ID, this ID must be stored in database and associated with the path of those images. Otherwise the database can never query any records with this ID if it doesn’t have any ID stored.
Now we need to go to your database, create one more table or add one more column in the table which have your path stored to store those IDs, and let them associated with those path. Use a parameter in this report for users selecting IDs. Then your goal will
be achieved.

If you have any question, please feel free to ask.

Hi all,
I have a table, Standard_Products, and i want to show an image in my report along with some other data.
I am using file browser to import the images at the moment.
Please advise what to do - at the moment the column is showing "Datatype" instead of the image itself.

Malfunction in generating word report out of an app (using the report generation toolkit)

I placed in my program some features that generate a word report with some graphics and text using the report generation toolkit. When I'm in the developing system everything works. But the point is that I have to create an exe for a user and in testing this the report is not generated (and no error msg occurs). Does anyone handeled this problem already and could give me some hints? Thx.

Hi muchalla,
the report generation toolkit for MS office depends on the version of MS Office (not the OS). You must generate your application for the version of MS Office or use some dynamic technic.
The different versions of the llbs you need are on the CD in a subfolder called compability.
Here I have asked if some ideas to do this will work. Until now I haven't got the time to verify it by myself.
You will find here more information about using the report toolkit with applications.

Images in a report

How can I import an image in a report and see it in a RTF
generated file? If I follow the help of the Report Builder 6i,
and after resizing the image, there are always problems in
MSWord - either the image has another size, or it is in some
other place of the report. If I generate the same report into a
PDF it is running well...
Thanks.

Hi,
Please refer this link.
I guess you have to place image into two location. Please refer the location path the below link then try to use same syntax

Images in a report column

Hi,
I'm working with obiee 11.1.1.6.1 and I need to add images in a report column.
I tried to follow the advices of Gerard for formulas as in
http://gerardnico.com/wiki/dat/obiee/image
but I don't see the images. I used the formula
'<img src="dir/dir/.../myimage.gif">' with data format HTML.
What wrong? Thank for your help.

Print Image in Oracle Report

I have an scan image in my report. I can see the image in the Layout editor but when the report runs all that comes out is a blank piece of paper. The image does not print.
The version of reports is 2.5. Does anyone have any idea why the image does not print.
Thank You
JK

Hi
If you are using a scan image (which is a bit map)in rep 2.5 and run them through oracle applications 11 and below you may have do lot of system level programming to support bit map images, because oracle apps 11 and below are charter based they do not support bit map. There may be a work around I had been trying for the past 2 years. But with apps 11i and rep6i this is possible.

What datatype should i use to store imaq image in sql database?

Hi there i am thinking of saving the imaq image into database for retrieval in my website so that it's like a stream but i don't like what datatype does labview store the image as.

You have two options for storing images in a relational database:
A. Don't put it in a database. Store it as a file, and store the pointer int he DB (as mentioned above).
B. Store it as a blob datatype. See here for more info.

How can I use or convert a imaq image to plot images back on waveform graph

Hi
I am currently opening and manipulating (rotate and resize) a PNG image using IMAQ Vision in LabView 8.2.1 This works well and I can display the Image on the front panel using a IMAQ Image Control.
In addition to this I would now like to display the image as a background on waveformgraph. I can do this with the original PNG file by reading it and then flatten it to a pixmap ie make it a Picture but this is of little use as I need to use the manipulated IMAQ image.
Therefor I would like to know how to convert the manipulted IMAQ Image to right Picture Format (without resaving) in order to use it on the PlotImages.Back property node of a wavefrom graph.
I very much welcome your suggestions as I feel it should be easy yet can not seem to solve it. Thank you for your time!!!

Hi Randall
Apologies for replying somewhat late but I have been out of the office for a few days.
Your suggestions and code helped me greatly and led to solving my query so thank you for that.
There is one more thing (well many many more but I will place new posts for those however that you might be able to answer for me.
Following your suggestion to use the image to array function I searched through more examples and found the code that did exactly what I wanted to do. Please see attached.
In this code a For loop is used to add 65793 to the color table. It works very well but I do not know why it is used exactly. Can you exlplain? I also realize I never made it clear that I use grayscale PNG files rather then color images.
Thanks again for your excellent help, it is much appreciated.

Why does moving the mouse over an IMAQ image display slow the GUI down so much?

I have a large application with several vi's running simultaneously under labview 8.6.1. When I mouse over an image display control in one of the vi's, everything slows down a shocking amount in all the other vi's. The windows task manager does not show a large increase in CPU use. My pc is has a quad cpu with 4GB of RAM, and the CPU and memory loads do not appear to be terribly taxing to the system. However, many of my vi's apparently come almost to a standstill if I just move the mouse in a circle around my image control.
This looks like it is largely a GUI display issue. If I make a new vi and put a while loop in it that only displays the iteration loop number to an indicator, I can see the iterating occurring, then stopping totally when I mouse inside the image display control. When I stop moving the mouse inside the control, or when I move it outside the control, the interation loop number jumps up, as if it had been incrementing behind the scenes the whole time. So only display of the interating was halted.
This problem occurs even if the vi with the image control is not executing. If the vi with the image control is open but not running, and I mouse over the image on it, the other guis all come to a screeching halt.
Does mousing in the image display control really utterly crush all other guis in all other labview windows? Is this an issue inherent to the image display control? If so, is there anything I can do about this?
Also, this issue is not entirely limited to display. I started looking at it in greater detail because this issue also exposed what I think is a race condition in my code. I have a vi that acquires an image from a ccd and puts it into an IMAQ image.ctl. This image then gets passed up to a vi up the call chain, and is put on a queue and sent over to be de-queued by a vi that has the image display control. Here's the kicker: when I mouse over the image display control, the image successfully gets acquired inside the subvi, and if I probe the wire leading to the output IMAQ image display.ctl, I see the image. If I simultaneously probe the wire coming out of the subvi one level up the call chain, the image gets lost about half the time. This only happens if I am mousing in the image display control IN A TOTALLY DIFFERENT AND SEPARATE VI. If I bump up the priority of the ccd image acquisition vi to 'highest priority', the problem only happens about 1% of the time, and I really have to mouse around to make it happen. Still, it's disturbing that mousing in the GUI in one window results in a failure of a separate subvi to simply pass an image up the call chain. I understand that IMAQ images are referenced rather than passed by value, but I don't see why there should be a failure to pass the image up the call chain. I've looked for a race condition, but can't find one.
Eric

I have finally been able to replicate the behavior that you are seeing on another computer once the image was large enough. Here are a few notes about this behavior:
First. The UI only slows down when the images are large, 16 bit images. The reason why this is unique to 16 bit images is that they can only be displayed on the front panel as 8 bit images. The workaround that Weiyuan suggested to change the 16 bit display mapping hints towards the root of the problem...that any time a mouse runs over the indicator, Windows asks the entire image to re-draw (having a separate indicator overlapping the image will create the same behavior). With a 16 bit image, not only does the image have to re-draw on the screen but the 16 bit pixels need to be mapped to 8 bits. When setting the 16 bit display mapping to Full Dynamic, this requires mor computation/pixel than 90% dynamic or one of the other mapping schemes.
This is expected behavior if your program is running and you're trying to display a large 16 bit image. To fix this behavior there are a couple options:
Change the 16 bit display mapping to something other than full dynamic. You can choose which 8 bits to display or if you want to map the bits.
Resize the image just for viewing purposes on your front panel (since you aren't going to view every single pixel of you image on the screen). You can use the IMAQ Resample.vi to do this. This will allow you to take your 1500x1500 pixel image and only display a 500x500 pixel version.
If you are interested in viewing small details of the large image, consider just displaying a smaller region of interest at a time.
Let me know if any of these solutions work for you. Good luck on your application.

IMAQ image out- what's the best way?

Hello forum,
I'm developing an interface to acquire a square image from an NI-DAQmx PCI 6221 on LabVIEW 7.0 and Windows XP. At present I am simply collecting my information from a physical sine wave generator on the bench, but eventually this will be used to process images from a CARS microscope.
My problem is that I am trying to figure out a user-friendly way of "buffering" all previously acquired images in the session, and then choosing one several of them to save as an uncompressed BMP. At the moment I am using two image displays; one for the whole image overview (picture indicator) and one to pan around and zoom on fine details (IMAQ image indicator). The IMAQ image indicator is also outputting to an IMAQ browser window, which I have modified based on the Browser Example.vi which ships with LV. However, there are several difficulties with this method.
Firstly, I'm not sure how to select an indexed image from the browser itself to save; the only way I can think of would end up wiring the IMAQ image out to the BMP writing VI, but that would only save the current image, and not necessarily the one the user wants.
Secondly, I haven't quite got the hang of combining case structures, event structures and while loops yet, so there's a very specific order things have to be done in or the program hangs, (e.g.. you must press the buttons: Acquisition - Unlock Browser - Stop in that order, nothing else works properly), and I'm pretty sure I've set the browser up wrong because every time I finish with the acquisition window, an error message appears.
Thirdly, it would be nice if I could hide the browser window until I've finished with the other window, but I can't seem to get IMAQ windshow to do that. I have boolean constants wired to Hide/Show and Set/Get but no matter what combination of false and true I use, the window appears anyway.
I will attach the VI and subVIs to this post in a zipped folder, and would appreciate any help you could give me. General constructive criticism on my wiring, methods, Rude Goldbergs, etc, would also be appreciated if anyone has the time, as I'm still pretty new to LabVIEW.
Thanks in advance!

DH is right about the difficulty in removing wind noise, but hoping it might prove useful, here is a hint I copied from a thread somewhere in this discussion list.
How to export audio from Final Cut Express to (free) Audacity and back again after noise removal.
1) download Audacity
2) in fce timeline, place in and out points at beginning and end of audio
3) select that audio clip, and that clip only
4)file-export-using quicktime conversion, in the pop-up box format as aiff, 44.1kwh 16bit stereo
5)open audacity, make sure box in bottom left corner says 44100
6)file-import-audio
7)go to file and select it, click choose
8) select part of audio with just wind noise, then go to effects noise removal, click get noise profile etc.
9)when satisfied, click file-export, click ok, close audacity
10)Open fce, drag your audio clip to the right hand end of clip. Move playhead to the in marking. Go to File-import
select your audio file, choose.
11) file appears in fce browser. Drag from there to overwrite and the audio goes into the track, perfectly synced
My apologies to whoever posted this hint, I tried to find the name to give credit. This really does work to get rid of room hum, but wind noise is a really different beast and this may not help. I suspect, as DH says, it will remove too much of the audio you want to keep. Hugh
