Save Image to Disk via CWIMAQ and CWIMAQVision in VB

Hi, I use NI 1428 CameraLink framegrabber and notice
a bug with saving image to disk via CWIMAQ object. It
adds 8 columns black pixels to the end of each image.
Savimg image to disk via CWIMAQVision is fine.
Has anybody experienced the same thing ?
Also, are the CWIMAQ buffers thread safe ?
I use them as a ring buffer, so multiple
threads may access the same image buffer at the
same time. I have used my own mutex to safe guard
each access. But I wonder if the thread safe is
built in.

I have never experienced the 8 black pixels using CWIMAQ save. However, I would use the CWIMAQVision.Write function anyway - this way you also get the vision information.
Here is a document that discusses multi-threading in IMAQ:

Acquire images with labview via firewire and TWAIN

Hi,
I have a camera from optronics. This camera is plugged to my computer
via a FireWire IEEE-1394 connection. The company optronics offers a
TWAIN driver for this camera: some files like TWAIN.dll and
TWAIN_32.dll. I would like to acquire images with labview and
communicate with the camera but I have no idea on how I should get
started.
The 3 main things I'd like to do are: 1) change the exposure time 2) snap images 3) see the images in labview.
I will really appreciate if someone could give me some ideas to get started...

Michael, From a
more general standpoint, what you'll need to do is use a Call
Library Function Node (located in the All Functions>>Advanced
palette) to call the necessary functions out of those DLLs. Before you
can do this, you'll need to know some specifics about what functions
are available in those DLLs and what parameters/outputs are associated
with them. This information is typically available in the product
manual or perhaps someone else with experience with your specific
device can speak to that. Once you know the functions necessary to
execute the desired operations, you simply configure a Call Library
Function Node for each of them and place them in your LabVIEW code.
Just
saw this and want to clarify on this. This is a total no-go! The Twain
interface is a very old technology from the days when Windows was a
cooperative multitasking environment without real tasks or threads. In
order for Twain to allow for some sort of multitasked integration into
an application it requires you to integrate the Twain handling into the
message loop of your application. As you do not have direct control
over the source code LabVIEW is written from, this is a very tedious
operation, with Windows message hooks and such, lots and lots of
semaphore protection to avoid race conditions etc. etc.
There is simply no way that you can do anything even remotely workable
just by using the Call Library Node. You will need a (rather complex)
external shared library that goes in between Twain and LabVIEW and
takes care of all the subtleties. I know for sure because I wrote such
a beast in the past.
Now there is a Toolkit from the French Alliance member Alliance Vision http://www.alliancevision.com/us/index.html that
does this. If you need Twain I would definitely go for this. My own
library is only to the point of what I had needed for a particular
project, (meaning it supports two specific scanners without issues) and
without any documentation for external users and I couldn't give it
away for free either.
Just want to warn you but there is a good chance that the Alliance
Vision Twain Toolkit does not really give you full programmatic control
of all the parameters of non-scanner devices and you won't be able to
avoid letting the Twain driver show the device specific configuration
dialog to manipulate specific settings.
In my own library I have low level functions to directly manipulate
Twain attributes but in order to be able to use that you would need a
through knowledge of the Twain specifications down to the API. That
together with the difficulties to support other devices I don't have
available, made us decide to not try to sell this Toolkit yet.

How to save files to disk without losing image quality

Hi, I'm a Visual Basic developer and I'm doing an acquisition system with a CCD camera and 1408 IMAQ framegrabber. I need to save the images into a hard disk. My problem is that when i begin to save images to disk, the acquisition's performance come down (the images gets slow).
Now I'm using the ActiveX CWImaq provideing by National Instruments.
I would be grateful if you would send me any advice.
regards.

There is a really good tutorial on the developer zone called IMAQ Acquisition, Images, and Displaying in Visual Basic , which talks also about buffered image acquisition in Visual Basic.
You can find built-in examples of how to do buffered image acquisition in the following folder with the default path: C:\Program Files\National Instruments\NI-IMAQ\Sample\VB\
I hope this helps!

How to play/record at same time and save image from video

i started working on a project and that made my life hell although it was so simple. reason was that i couldnt find small/simple code to understand problems and no proper documents. . finally i have done that. and here is the code (without much complex code of interface). it shows vidoe, records a small part of it at start and takes a snapshot (no buttons or events involved). hope it might help someone starting to learn JMF.

so here the code. all messed up. coz i have just completed it and havent worked on interface or formatting this code properly (didnt have much time). but hope it will help. ask me if u have any questions. dont want others to have those basic problems that i had to face.

u did a good effort for the JMF beginners i appreciate that....thanks i lot....i need you help in a project in
which i have to connect to a d-link 950G IP camera and process that
mpeg-4 stream (i know there are some problems in JMF and mpeg4) and show it over applet of JFrame.

Firefox 32 hangs on "Save Image" dialogue box Windows 8.1..Tried everything

I clean installed windows 8.1..
then installed all latest drivers for my devices...
installed latest Firefox..
Then i needed some images ..so opened Google image search and searched images..opened one image in a New Tab.. clicked "View Image" and tried saving it by right clicking and selecting "Save Image"..
First it took a lot of time for the "Save Image" window to appear..
and then it hanged...
I tried doing it again by force closing and re-opening firefox..but same thing happened even if the Image is small like 100X100 pixels..
Then I opened the mozilla support questions and tried the following solutions some other users have suggested;
1: Opened FIrefox in safe mode (Same thing happens)
2: Disabled addons (Only addons i had was flash downloader and downthemall! - Same thing happens)
3: Reset Firefox (No use)
4: Disabled Hardware Acceleration (No Use - In fact firefox hangs as soon as I "View Image")
4: reinstalled Firefox (No Use)
5: Uninstalled my ATI Radeon display drivers (No Use)
6: Disabled JAVA and Flash (No Use)
So this problem still persists....and its quite annoying
Another thing I have noticed is when i try to save/download other files like mp3 or email attachment or pdf .. The window where it shows whether to Open or Save the file opens immediately..but takes around 15 seconds before I can actually Select and option and click Ok.

SOLVED - Atleast for Now....
So I think I have found the solution to this problem...
I reinstalled windows 8.1...
Then did 2 things..
1: Disabled Skydrive from Group Policy Editor and selected Always save files to local drive.
2: Disabled Bing Search from local file search (Windows Key + C-> Settings->Search and Apps->Search)
Installed Firefox..
and Now I don't have the problem...
I am going to install java, Flash and Addons ..and check again if the same problem occurs again..
Will update what happens..

Camera RAW JPG 'Save image....' dialogue reversal?

In camera RAW, to save a JPG you click on the 'Save image...' dialogue and another window opens with the JPG options.
To skip this window and directly save the image, you hold down the ALT key and click on the 'Save image'.
Is it possible to reverse these settings, so that if you want the JPG dialogue to open you have to hold down the ALT key and to save without the dialogue, you just click on the save button?

Thank you, Mr. Spock!
Very true. it would be counterintutive.
But my left hand is stiff from holding the ALT key!
Is it possible to redefine the keys in camera RAW?

TS1702 I can not save image to camera roll from google images after I downloaded IOS 6. It keeps saying image save failed.

After I downloaded IOS 6 on my iphone 4s i went on google images and clicked on a picture. I then tried to save image to my camera roll and was asked do I want to put image in camera roll. I pressed no by mistake and I have not been able to save any images since. I deleted google off of my iphone and reinstalled it
and it still says image save failed. I can not find an option on the google app to change the setting or on my iphone in settings.

OMg!!i had the same problem like just now and what I did was I went to settings, went to reset and then I only rest the location and when I went to google again, they asked me if I wanted to use my current location and I said yes and then I tried o save a pic and they asked me of they can access my pics and u have to say yes
HOpe I helped

Can't save images from email

When I get an email with an image in it, if I click on the image, all of these options are greyed out: Quick Look, Save Image, Assign to Contact, Copy and Print. How do I fix that? I want to save images to my camera roll that people send me.

I can send if I use:
// Create your new message part
BodyPart messageBodyPart = new MimeBodyPart();
String htmlText = "<H1>Hello</H1>" +
"<img src=\"cid:memememe\">";
messageBodyPart.setContent(htmlText, "text/html");
// Create a related multi-part to combine the parts
MimeMultipart multipart = new MimeMultipart("related");
multipart.addBodyPart(messageBodyPart);
// Create part for the image
messageBodyPart = new MimeBodyPart();
// Fetch the image and associate to part
DataSource fds = new FileDataSource(file);
messageBodyPart.setDataHandler(new DataHandler(fds));
messageBodyPart.setHeader("Content-ID","<memememe>");
// Add part to multi-part
multipart.addBodyPart(messageBodyPart);
but if I try to read message (html and image inside it) sended from Outlook? i can't find images.
messageBodyPart.getHeader("Content-ID");
returned null.

TWO CRITICAL BUGS: 1) File, "Save Page As" and 2) right-click the picture and select "Save Image As", both do not work at all in Firefox 27, 28, and 29!

Note: capitals are used only to highlight important words.
PLEASE, TAKE THESE COMMENTS ON TWO CRITICAL BUGS VERY SERIOUSLY BECAUSE THE BUGS DESCRIBED BELOW ARE SO CRITICAL THAT I CANNOT USE THE LATEST VERSION OF FIREFOX UNLESS THEY DO NOT APPEAR IN THE LATEST VERSION AND THEREFORE I AM FORCED TO REVERT BACK TO FIREFOX 26.
I have Windows 7 64-bit and Firefox 26. I could not install Firefox 27, 28, and 29 due to the persistent presence of the two critical bugs described below. I have 8 GB of RAM and an Intel quad-core processor and a lot of hard disk space available.
I installed Firefox 27 and then Firefox 28 a while back and these two bugs described below were still present and now I have just checked again with Firefox 29 by installing it and yet again, these two bugs described below are present!! UNBELIEVABLE THAT THESE TWO CRITICAL BUGS ARE STILL PRESENT IN FIREFOX 29 WHEN I CLEARLY INFORMED YOU ABOUT THEM IN THE HELP, SUBMIT LINK OF FIREFOX!!
I am forced to revert to Firefox 26!
First, I use Windows 7 64-bit and I always use Firefox with at least 120 tabs opened. BUT I have 8 GB of RAM, an Intel core i7 quad-core processor and more than 1 TB of hard disk space. Consequently, I do not understand why I would have these two critical bugs.
With Firefox 26, I also have at least 120 tabs opened when I start Firefox and I do not have the two critical bugs described below, therefore I do not believe that the number of tabs is the reason of the two critical bugs that are present in Firefox 27, 28, and 29.
---FIRST CRITICAL BUG:
When I open ANY web page and do File, "Save Page As", the window that is supposed to open to locate the folder where I want to save this web page does NOT open at all, even if I wait a long time to see if it opens.
Same problem happened with Firefox 27, 28, and now 29!! When I reverted back to Firefox 26, this problem did NOT happen anymore!
---SECOND CRITICAL BUG:
When I use Google Images, for instance entering model in the search field of Google Images and then pressing enter.
Then I select any picture, open to a new tab this selected picture, then open a new tab by selecting the option View for this picture. Then right-click the picture and select "Save Image As".
Again, the window that is supposed to open to locate the folder where I want to save this picture does NOT open at all, even if I wait a long time to see if it opens.
Same problem happened with Firefox 27, 28, and now 29!! When I reverted back to Firefox 26, this problem did NOT happen anymore!
---THESE TWO CRITICAL BUGS DO NOT APPEAR WHEN I USE INTERNET EXPLORER 11.
I have no idea if you will be able to reproduce these two critical BUGS but I can assure you that they are not present when I use Firefox 26 and they are present when I use Firefox 27, 28, and 29. More, be aware that I have at least 100 tabs opened but I also have this same number of tabs opened in Firefox 26 and yet I do not experience these two critical bugs when I have Firefox 26!
Once again, these two bugs touch at two vital, critical very basic functions of Firefox and therefore I will NOT be able to use any version above 26 if these two bugs are still present, as they are present in Firefox 27, 28, and now 29!!!
Please, make it a priority to solve these two critical bugs. Thanks.
I did read a post related to the same issues “Firefox stops responding when trying to "save page" or "save image" | Firefox Support Forum | Mozilla Support” at https://support.mozilla.org/en-US/questions/991630?esab=a&as=aaq
I am still reading it again to try to figure out exactly what the person did to make his problems be solved, as the post is not clear at all on what solved the problems!
In any case, all the suggestions proposed in this post do not work and I surely cannot do a system restore when it is obvious that the two bugs do not appear in Internet Explorer.

First, I sent an email to the author of PhotoME to inform him of the serious issues his addon caused with Firefox latest versions.
Now, for those of you who do not have the PhotoME addon and yet experience the same problem that I had and that I described above, I suggest the following strategy.
As PhotoME did cause these problems with Firefox latest versions, I am pretty covinved other addons probably might cause these problems too. Therefore, adopt the following method.
Test one addon at a time to see if this particular addon is behind your Firefox issues like the ones I had.
So, disable one addon only at a time. Then close your Firefox and restart it from scratch and see if you still have your Firefox problems. You must restart the Firefox browser from scratch. If you still have these Firefox problems, re-enable the disabled addon, restart your Firefox (again!) and repeat the same method for every single addon that you have.
Try to be selective by choosing first addons that are more likely to cause your Firefox problems such as not very well-known or not very popular addons (like it was the case for the PhotoME addon).
If this method works or if it does not work, report it on this web page so that others can be helped with your comments.
I hope this method will help you because I was really upset that I had these Firefox problems and I first thought it was the fault of Firefox, only to discover later that this PhotoME addon was the culprit and had caused me such upset.

After I rt click and hit "save image/page as" the dialog box doesn't open.

When I try to copy an image or a web page I get no dialog box that opens after I right click and select "save image/page as". The option to send link works.

Sorry, here the information that is required:
Version 11.0.4.2 - CS6
Installed recent updates: Yes
OS: Windows 7 Pro (Service pack 1) 64 bit
Model: HP Z420 Workstation
Processor: Intel Xeon CPU E5-1620 @3.60Ghz
Ram: 8Gb
Has it worked before: yes. It started after I opened a project (trough "open project") because double clicking on this project gives the follwoing error: "The directory name is invalid". Via "Open project" I could open it.
Do you have any third-party I/O hardware (e.g., AJA, Matrox, Blackmagic, MOTU)? No
Quicktime 7 pro installed
Do you have any third-party effects or codecs installed? Yes, Optical Flares & Trapcode. But is unrelated since it isn't a specific project.

Are you using the ray-traced 3D renderer? No
Thanks for the help. If you need any other info, let me know

Scroll Bar missing on Safari web pages and unfamiliar screen saver image

I recently upgraded my OS X from Panther to Tiger v. 10.4.11 and upgraded to Safari 3.1.2. Now the scroll bar down the right side is missing from the open web page in Safari. Where did it go and how do I get it back?
Also, unfamiliar images appear, something like a screen saver when I leave my computer for a
few minutes without putting it to sleep or shutting it down. It's a black/white/gray portrait of
a woman and as the picture moves around the screen, the image magnifies. I have no idea
where this image came from nor how to get rid of it. Any ideas?

Hi Busy1, and a warm welcome to the forums!
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it finishes.
The usual reason why updates fail or mess things up, or things don't load/run, is if Permissions are not fixed before & after every update, with a reboot... you may get a partial update when the installer finds it doesn't have Permissions to change one obscure little part of the OS, leaving you with a mix of OS versions.
Some people get away without Repairing Permissions for years, some for only days.
If Permissions are wrong before applying an update, you could get mixed OS versions, if Directory is the slightest messed up, who knows!
If many Permission are repaired, or any Directory errors are found, you may need to re-apply some the latest/biggest updates again, or even do an A&I if you have enough free disk space.
The combo update for PowerPC-based Macs...

The combo update for Intel-based Macs...
http://www.apple.com/support/downloads/macosx10411comboupdateintel.html
Repair Permissions after re-install, then reboot again.
If all the above do not resolve the problem, then it's time for an Archive & Install, which gives you a new OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space...

Might try this for Scroll Bars...

few minutes without putting it to sleep or shutting it down...
Check System Preferences>Desktop & Screen Saver>Screen saver Tab for that.

Lousy web "Save Image" quality? And best res for others?

Double header here. iTouch 2nd Gen:
1) When I "Save Image" from the web via the iTouch, it looks like total crap when opened in the device's photo library. Blurry.
2) When working with photos on my desktop, is there an optimum size/resolution I should set them at for iTouch syncing in particular? Or does it automatically get resized anyway when it syncs to the iTouch? I don't care what they look like via iTunes--I'll save versions just for the iTouch--but I don't want to send files that are unnecessarily large and use more space than needed.
Thanks~

1. known problem. for now we live with it
2. itunes will resize the photos (optimize) during synching, so don't worry about their original sizes on your pc (or Mac)

How the **** do i get back my library i was just using.No didn't save image or restore been using it for months the same way no tells me to choose or create a library and my previous versions don't recover

Do you have a back up?
If not you're into using file recovery software like File Salvage - you can download a free trial and it will scan the disk for you and tell you with might be recoverable. Actual recovery will require that you purchase the app. There may be many files with the same or similar names. Always recover the largest file size.
There are other such apps. Search on Macupdate or the App Store

How to save image from Clipboard to disk?

Hello;
I want to take a screen capture of the entire screen, not only the front
panel and save it to a file. Don't care about the image format right now.
I am able to simulate a PrintScreen key using a call to user32.dll
"keybd_event" in Win2K, but I am stuck here. How do I get that image that is
now in the clipboard to disk? I have searched NI's website high and low, and
nothing yet.
Thanks is advance,
/JB
LabVIEW 6.1

I've kind of done it "programmatically".... using the "system exec.vi" I've
started mspaint.exe... then, I paste the image and save it to disk (too bad
the last two steps are manually done!!!)
The limited documentation on System Exec says it has a Standard Input
terminal... but, I haven't figured out how to programmatically send CTRL-V
or ALT-E to the MSPAINT application as command inputs...
Any further ideas?
Bill

I want to save a converted PDF (via your cloud product) onto my desktop. I want a hardcopy on my drive and not a link via Chrome to your cloud. How do I do this?

Hi WalterFranco,
When you convert your files using ExportPDF or Adobe PDF Pack, files are automatically saved to your online account. But, you can log on to your account at https://cloud.acrobat.com/files, select the file that you want to store on your hard disk, and then click the Download link at the top of the file list.
Please let us know how it goes.
Best,
Sara
