Save image fast

Hi, I am using a Basler l104k line scan camera and NI pcie-1427 frame grabber. I want to save my images continuously and each image is 10 bit * 2048 *256 *256.  I am using IMAQ write file to save it into PNG file and it takes about 10 seconds to save one image. Is there any faster way to save these images? Thanks!

When you use the IMAQ cast image function to cast the 10bit image into an 8bit image, do you lose data in the process?  [...]  If data is being discarded, how does the program choose which data is discarded?
You can control the behaviour by specifying the number of shifts, see parameter "# Shifts" in the specification of IMAQ Cast Image. In your case, a "shift value" of 2 would keep the 8 most significant bits.

  • Firefox saves images to wrong location, but only when using "View Image"

    For a while, I have had the problem above. I can save images just fine if I don't use the "view image" function first, with the images going to the intended folders.
    Just to clarify, unlike some of similar problems I have seen described here, I am perfectly happy with Firefox remembering where I wish my pictures to go, on a site to site, or model to model (within the same site) basis.
    The problem lies in that if I use the "view image" function, either in a new tab, or in the existing one, Firefox will often prompt me to save in a random folder where I have previously saved a picture. It will even suggest folders that I have not accessed for days.
    Example:
    I save image A to folder A, by right clicking the image and selecting "save image as".
    I then (immediately after this), right click image A again, select "view image", then right click the resulting picture, and select "save image as". Now there is a fine chance that it want me to save the image to some other (previously used) image folder, even if I have not used the folder for a while, and even though I have just saved the same image to folder A.
    This problem persists with multiple image file types, on multiple sites (I just tried it with someones avatar in this forum, and it wanted me to put it with my holiday pictures from 3 weeks ago).
    I appreciate any assistance you can give - jinxie
    FYI; If I "one-click" a file (like an mp4) to download it, it goes to my main / default download folder as normal.

    This is because Firefox will track where you have saved images or other files from the website domain. Then whenever you select to save the file to your computer, Firefox will start the Save As wizard in the latest folder that you have used last time.
    Here is an example:<br>
    If you save an image from the domain <code>123.com</code> into the folder <code>123</code> it will save there. Then you save an image from the domain <code>456.com</code> to the folder <code>456</code>. Next you save a different image from the domain <code>123.com</code>. The save as wizard will assume that you want to save it with the other image from that domain and will automatically start in the <code>123</code> folder.<br>
    This can make saving files faster and more organized, however not everyone wants this feature enabled.
    To disable this feature you can do the following:
    #Go to <code>about:config</code> in Firefox
    #Locate the <code>browser.download.lastDir.savePerSite</code> string
    #Change the value to <code>false</code>
    This should fix the issue, but please report back if it doesn't.

  • How do I change "save image" to save as jpg or gif rather than an html pointer to the image?

    When I try to download images it is saving them as an HTML file instead of the actual image. I want to save images in their native jpg or gif formats as they are on the web. Downloading wallpapers for example is not possible. Without this I'm not going to stick with Firefox which is unfortunate because so far I love everything else about it, especially sync. I tried to download a Buffalo Bills helmet to use as an icon for a Bills fan forum which I wanted a Firefox shortcut for on my homescreen. I had to use the Android browser to do that because of this problem. Ridiculous!

    Unfortunately, Firefox for Android works quite differently than desktop Firefox in this regard. On the desktop, if you open about:config and set browser.download.useDownloadDir to false, then you prompted for the save location and file name. On Android, this simply stops Save Image from working.
    I was able to access the file by renaming Images.htm to a real file name using the ES File Explorer app. But... if you save images often, that would get old fast.
    Note: I think the name Images.htm came from the Google images results page that I was saving from, and the file name will depend on the site. When I saved from a site where the images had their own names, .jpeg was appended instead of .htm.

  • After a few downloads, using "Save image as..." causes Firefox to download the image again even though its already on the screen.

    You would think that having downloaded an image and displayed it on the screen, Firefox would be able to save the image to disk (using right-click, "Save image as...") without need of downloading it all over again. But that's exactly what it does after just a few image saves.
    This can be both expensive and time consuming when I happen to be working via a mobile or dial-up connection, which is often.
    Any ideas?

    As an addendum, the 10.6.8 OS has also been sluggish when I log in or out of my computer (my old PowerBook G4 boots faster after being off).  Otherwise, everything else seems normal.

  • Very slow when using "Save Image as..."

    When I try to use "save image as...", firefox almost always hangs and then eventually downloads the file, then returns control to me, whereas before firefox 5, this was instantaneous and I could right click and save on several in succession without the long delay...please help??

    As an addendum, the 10.6.8 OS has also been sluggish when I log in or out of my computer (my old PowerBook G4 boots faster after being off).  Otherwise, everything else seems normal.

  • File names when using "Save Image As..."

    I am using Safari for Windows to read Gmail. When I open an image and want to save it, I right-click on "Save Image As..." Instead of displaying the images file name in "File name:" it always says "mail" requiring me to re-type the file name for every photo I save. It also saves every file as "All Files" instead of as a jpg image which my photo viewer does not recognize as even being there.
    Any help would be appreciated.

  • Acquire and save images at high frame rates

    I am attempting to acquire and save images at a rate of 3000 fps for approximately 100 ms using a JAI 6740GE GigE camera, LabView 2011, and IMAQdx.  I can acquire the images at the necessary rates, but am dropping images when I try to save them.  The current test program I am working with contains a producer loop for acquiring the images, converting them into an array, and putting them into a queue, and a consumer loop to write the arrays to a TDMS file.  Currently I can acquire and save the images at a rate of approximately 1200 fps before I begin losing a few frames.  The code is attached below.  I would appreciate any ideas to be able to save the images without dropping frames.

    Hi Rox,
    How are you verifying that you are loosing the frames during the saving and not during the acquisition? Are you able to determine where you are dropping frames? Is it at the beginning, the end or randomly? Thank you!

  • "Save image" button of Camera Raw does not save JPEG with modifications made.

    I am using Bridge CC to process my RAW images and make modifications to some JPEG images as well.  I have no need to further alter images in Photoshop at the moment, so I do all modifications in Camera Raw. After altering my images, I then press the "save image" button at the left bottom corner of Camera Raw and choose the settings to save in JPEG.  However, when I upload these JPEG images to a website or when I email them, the image is uploaded without the modifications I had done!  It seems to me that Camera Raw is saving JPEGs the same way it does for RAW images, in a non-destructive manner, only attaching instructions for the images to be displayed properly on Photoshop. But when I save an image in JPEG, I expect the image to be saved entirely with the modifications I made while still keeping the original RAW file.  What goes on then?  What is Camera Raw doing and how do I get to save a modified image in JPEG with Camera Raw?  Would you please explain?
    Many thanks for your help,
    Beza

    Hi,
    What version of camera raw and operating system are you using?

  • 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.

  • Downloading images used to go automatically to the last folder used to save images, even when reopening Firefox. In just the past few days, possibly coinciding wih the most recent updates, the folder defaults to the 'Downloads' folder. This is most annoyi

    Downloading images used to go automatically to the last folder used to save images, even when reopening Firefox. In just the past few days, possibly coinciding wih the most recent updates, the folder defaults to the 'Downloads' folder. This is most annoying. What happened? Internet Explorer 8.0 did the same thing. This was one of the reasons why I started using Firefox to download all images. I went into Tools>Options and it only lets me set another folder. I dont want to set a specific folder I want it to always go to the last folder used. So what gives?
    == This happened ==
    Every time Firefox opened
    == possibly when the most recent updates were installed, a few days ago

    Thanks jscher 2000. I guess I didn't make it clear. "It restarts with all the addons activated, and resumes with the tabs that were open before closing it." IE, it's running fine now with all the extensions activated. Everything is OK now.
    So something in the Firefox code was causing the bad behavior. It's not essential that I find out what the problem was - I'm just curious. And if anybody else has this same problem, it might be nice to have it corrected at the source.

  • Right click - save image keeps saving to wrong location

    I moved my firefox profile over from my old computer.
    Now when i do right click -> save image as, it SOMETIMES defaults to C:\Users\test\Documents. Which was my old default location.
    I have changed it to C:\Users\Question\Documents on my current computer but it randomly changes back to C:\Users\test\Documents. I cannot find a pattern that causes it to change, but it seems to happen mainly after i restart my computer (not always though).
    Can someone please tell me how to get it to change to C:\Users\Question\Documents PERMANENTLY?

    Oh right i forgot the first answer to every problem is "reinstall firefox".
    Does anyone have a suggestion that does not involve reinstalling firefox and wiping my profile?

  • 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..

  • Firefox stops responding when trying to "save page" or "save image"

    Windows 7 64 bit and Firefox 28. When trying to 'Save Page' or 'Save Image' the save dialogue window is nearly blank, then info bar shows 'not responding'. I have tried all the tips in the support pages. Resetting Firefox, Starting Firefox in 'Safe Mode'. Upgrading graphics driver to latest version. Turning off 'Hardware Acceleration' in options. Nothing resolves the problem. This issue has only recently started, the last time I tried saving an image it worked fine, certainly prior to Microsoft's most recent 'upgrade Tuesday'.
    Edit:
    Checked the save dates of the last images I successfully saved from within Firefox and compared them to my windows update log. The Microsoft March 'Update Tuesday' was installed on March 14th. My last successfully saved Firefox images were saved the following day on March 15th. Thus it is unlikely that the Firefox saving issue is a result of a Windows Update corruption. So the question is what changes have Mozilla made to Firefox between 15th and 24th March 2014 ???

    I understand that finding a root cause is ideal, and I would be happy to further investigate this with you.
    Since it is still happening in Safe Mode [https://support.mozilla.org/en-US/kb/troubleshoot-issues-with-plugins-fix-problems please try to troubleshoot the plugins and extensions]
    The other route is to troubleshoot the downloads folder and antivirus to make sure the downloading of the image is not having an issue either. [http://mzl.la/LJ0h2w]
    In the meantime there is an add on that enables this [https://addons.mozilla.org/en-US/firefox/addon/save-images/ Save Images]
    Please post back with your results, there have been other reports, but no issue filed yet.
