Saving Images to memory
I have a PCI 1408 card. My labview program is supposed to capture images when triggered. How do i store the images to the computer memory and called it back when i need it? other then using the buffer LL ?
By default, images acquired using High Level grab, snap and sequence are already stored in system memory. There are also low level examples showing how to do image acquisition into onboard memory. As you will see in the examples, the difference is in the IMAQ Configure List.vi where you can specify the memory location for the image buffer.
To access images stored onboard, you will need to use the IMAQ Copy.vi to copy the image from the onboard memory into system memory. If not using onboard memory, you can directly access the captured images via the pink image wires.

Whilst tethered can my images be saved onto a memory card or is it going to be by passed?
Shooting whilst tethered to a D7100 can my images be saved onto a memory card? Or is the images going to by pass card and go straight on to computer?
Thanks
TapiwaCould it be because the SIM card got damaged while I cut it to fit the IPhone?
Very likely. Hard to believe the carrier in Mexico doesn't have a micro-SIM card available.
Or somehow the Chinese carrier found out and locked it?
No, which is not possible.
What can I do? Get a new SIM and see if it works again?
Get a micro-SIM from the carrier in Mexico that you don't have to manually cut down. If that carrier doesn't provide one, switch to another carrier that is not so low-budget. -
What is the best way to capture RGB8 image to memory for later write to disk?
HI-
I have been using the code below for some time now but wonder if an expert can take a look and let me kown if there are ways to improve it. Problem I run into is that I preallocate the memory beforehand (camera.buffering[]), and with a 5 MP camera, this takes up a lot of RAM. It seems like when I am running this program in debug mode all day and constantly start/stop it without allowing it to free the memory gracefully, i eventually bog the system and start getting Out of Memory error -12, in other places in my code such as DisplayBitmap or GetBitmapfrom File. Is this all related to how much memory I am trying to allocate prior to begining the camera capture routine below? Am I not allocating and free-ing it properly?
Code is below for how I grab the image and then send to memory usign memcpy. Is there a better, more efficient or faster method? I have removed error checking/etc from code below simply to save space. This operates at 15 fps.
I also included my allocation and free-ing code, too.
Thanks in advance.

//caemra capture loop//
camera.dxerror = IMAQdxGrab (camera.session, camera.image, 1, &camera.bufNum);
stat = imaqRotate2 (rotateimage, camera.image, camera.rotate_image, pixval, IMAQ_BILINEAR, TRUE);
stat = imaqScale (scaledimage, rotateimage, 4, 4, IMAQ_SCALE_SMALLER,IMAQ_NO_RECT);
stat = imaqGetImageInfo(camera.image,&camera.info);
stat = imaqDisplayImage (scaledimage, 0, FALSE);
memcpy (camera.buffering[camera.count], camera.info.imageStart, camera.info.pixelsPerLine*camera.CAMY*camera.bytesperpixel);
//memory allocation code//
camera.buffering = (int **)malloc(camera.maxcount*sizeof(int*));
for(i=0;i<camera.maxcount;i++)
camera.buffering[i] = (int *)malloc(camera.info.pixelsPerLine*camera.CAMY*camera.bytesperpixel);
// free allocated memory code//
for(x=0;x<camera.maxcount;x++)
free(camera.buffering[x]);
free(camera.buffering);How many images are you storing in RAM? Typically when I need to work with tens, hundreds, or even thousands of images, I save them to the hard drive after I capture them as a PNG with 1000 quality. Sometimes I process them before saving, sometimes I process them offline from the saved images depending on the application. If you don't need all of the images simultaneously in memory at once, just save them to PNG. If you only process one image at a time, only allocate enough memory for the processing you need to perform on a single image.

N96 capturing but not saving images
Hi,
I've had an N96 for ages without issue but recently it has stopped saving images.
Camera works fine, can take photos and they display on the screen as captured but then, unlike before, they are not automatically saved.
Have checked memory space - loads left
Restored camera settings - no change
Have checked other folders and "all photos" rather than just gallery - still no sign of latest image(s)
Any help..?Rob, the option to retain the original Raw file (in this case CR2) is in conversion to DNG done from the Library module, not to conversions done during importation when Copy as DNG is selected, because in this case the original remains on the card.
CDPhoto, if, on the Import page, you select Copy instead of Copy as DNG, your files on the hard disc will be CR2s. If your really do want them converted to DNG, in the right side panel select File Handling/Make a Second Copy To: and designate a location. The second copy will be CR2. -
has anyone had the problem where, when they select option and tap an image (in my case i pulled one from my email using an image i uploaded from my drive) and gotten an error that says "there was an error saving image" and your only option is 'ok'? i've read other forums and understand that jpeg's are the ideal form, and this had a .jpg extension.
any thougths anyone?
so many thanks in advance.

Saving image to a folder not working on azure
I am saving image
files to a folder in my application and saving its path in database . Image uploads working fine when I am running locally
and its path is also storing.When I deployed it on azure it
gives an error that " An error occurred while processing your request ". I have two tables in my database . First one where text is saved is working fine on azure but image upload thrown this error.
I am using this code
to upload
image and its works fine when I am running locally. Need help ?Hi,
Have you made any progress ?
May I ask what application is it that you are running ? You mentioned that it works locally but not when deploying to Azure. Have you checked the connections strings?
If you are still having any difficulty in understanding the code, perhaps you could post it on the below blog.

Data type for Saving Image in SQL database
Hi,
Which is the best way for saving images in the database? Filestream or Varbinary(max)?. Will the Varbinary max comsume much space or it will only take the actual size of the data?I've used FILETABLE for storing images in SQL 2012
You can configure it to have transact and non transact access if you want

How do I stop Firefox from grabbing my saved images and coverting them to Firefox?
I am working on images in Dreamweaver and Adobe Photoshop, and when I try to save them, Firefox coverts them into Firefox images with a Firefox icon and then I can't edit them properly in Photoshop or Dreamweaver. How do I stop Firefox from grabbing my saved images? in English
I will try that, but it's pretty time consuming to have to check that for each of my images. I am a web designer and I work with a lot of images.
Is there any way to set that globally for all of my saved images? -
Saving image using mobile into sap R/3
We are using sap mobile platform version 2.3 and our client requirement is to save images using mobile apps.
We already saved images in mime repository but for this we have to required client modifiable , but due to security reason we can't do this.
Please Help.Hi Nilesh ,
I had a scenario to attach image to pr05 transaction from mobile, so that when click view attachment button in pr05 i can see the image . My code is based on that .
it is the function module with import parameter base64 string and filename ,last three letters of the file name proceeding the . is the extension
in your case you need to create custom object type instead of BUS2089 .

I save a lot of images using firefox, often times from a large batch or series of images. It used to be that I would click on a previously saved image and the entire file name including the file extension (i.e. image_example.jpg) would appear in the "save as" line. Now when I click on a previously saved file, the file name appears without the file extension (i.e. image_example). Which means I have to manually type .jpg every time. For a large collection of images that I am hoping to use the same root file name and then add chronological numbers at the end, this has become incredibly frustrating, especially as it is a previously unnecessary task.
I am using a new Macbook Pro and maybe there's something Apple related to this...? It did not happen on my old PowerBook G4. I have file extensions turned on in System Preferences.
It should be noted that I have searched high and low and have even gone into the Apple Genius Bar where they were just confused as I was and of course ended by urging me to use Safari (shocker!) as it has all kinds of new extensions and bells and whistles. I seriously feel alone on an island with this dumb, hard to google problem. Thanks so much for any help anyone out there might have.
I mean: is this as simple as changing a setting in about:config?
Your assistance is greatly appreciated.Thanks for your response Mylenium, however like I mentioned multiple times, I did change all of my trackpad/scrolling settings in system preferences. And if I wanted to use a normal mouse (or a tablet), I would've gotten an iMac instead of a MacBook Pro. I travel often and work all over the place, not always with access to a decently sized workspace that would be required for using a mouse or tablet.

Saving image in ms sql database.
Hi all, i have a problem saving image in the database.i used
request.getParameter("imagename"), to get the content of the textfield in the html file but the problem is that it omits the filepath and gives me just the image name and that gives me an error.. Pls help meYour actual problem is less or more web browser related. The right way is that the browser should only send the filename, but a certain widely used browser developed by a team in Redmond would send the full file path as it is at the client side, which is completely wrong.
The bigger picture what you're trying to achieve, uploading a file from the client to the server, shouldn't be done that way, simply because this isn't going to work at all if the client runs at a completely different machine on the other side of the network than where the server runs. You need to send the actual file contents to the server. Just set the form's enctype to multipart/form-data and parse the body of the request to get the actual file contents. To ease the work I recommend you to use Apache Commons FileUpload API for parsing the multipart/form-data request. Go to their homepage and check out the 'User guide' and 'Frequently Asked Questions' how to use it and for some tricks. -

Saved image displays differently outside Photoshop
When I save an image I've been working on in Photoshop, then open the saved file outside Photoshop, the image looks quite different than it does inside Photoshop, much drabber and less saturated. I have both Photoshop and the display program set to sRGB. I figure that I should have consistency within the monitor, whether it's calibrated or not. I'm sure I'm missing something basic here. I'd appreciate any help here, because my prints wind up drab, too. Many thanks!

I overlooked one switch in the Save dialog. Now the images display correctly.
Can you be more specific, please?
Were you saving images without a color profile before, and some application(s) in your system were displaying them improperly?
Problem is, in that case one wouldn't really expect to see the kind of difference you describe unless your document profile really wasn't sRGB IEC61966-2.1.
Is it possible you're editing your images in the Adobe RGB 1998 color space? That could happen if you're opening images through Camera Raw, as the color space it's set to deliver is configured separately (via the link at the bottom-center of the Camera Raw dialog) from the Photoshop defaults.
By the way, if you don't already know, you can easily set the status block in the lower-left of the Photoshop window to show you the color space of your current document:

but images saved from my phone or camera images that have not been manipulated upload fine, What am i doing wrong?Save/Export them as JPG. Photoshop defaults to PSD, so make sure you select JPG and not just rename the file to .jpg.
There are two ways to save them as JPG: Regular Save as option or Save for Web & Devices
