IMAQ JPEG image conversion problem string

Hi, I'm using the format JPEG decode VI to decode an image string I get a camera at Black fins. It works fine when I run VI himself, but when I use it as a subvi the program crashes. Anyone have advice?

This is a picture of my program

It's the way the file is returned to the camera

'I '. «#IMJxs0s1s2s3...» » Enter the JPEG compressed video image

x = size of the frame in pixels:
1 = 80 x 64, 3 = 160 x 120, 5 = 320 x 240, 7 = 640 x 480, 9 = 1280 x 1024

s0s1s2s3 = size of the image in bytes (s0 * 256 ^ 0 + s1 * 256 ^ 1 + s2 * 256 ^ 2 + s3 * 256 ^ 3).
... = full frame JPEG

Note that sometimes the 'I' command returns nothing if the robot camera is busy, then the 'I' command should be called as many times as necessary until a framework is returned

I changed the format JPEG decode VI by changing the plans of red and blue color. I don't know if this caused the problem though.

  • IMAQ write bmp conversion problem

    I automatically tries to get a 3-d chart to write the content of the image in a bitmap image, I am currntly using the property node "get image", and then the 'write' but gives a bitmap of poor quality as well. I found simply right-clicking on the front panel and with the help of "copy data" and then paste it into ms paint gives really good quality. (see attachment) So:

    There are two ways to write a bmp file, as I discovered: [n/b, I am running 8.2 lv]

    writing & imaq write

    the of writing requires an input of a cluster with the image data it contains in the form of a 1 d table, the bmp of writing imaq simply to an input image.

    Q: is there a good way to convert between them as the of writing returns less Muslim bitmaps imaq writing is capable of.

    Or is it a way to dirrectly read an image other than 'get image' use 3d as a method node? or data 'copy' lets get data wrote?

    Hi John,.

    If you set number of bits of the image get invoke node to be 24, that this feature will also define the bitmap that you write to drop to 24 bits.  Simply connect to a constant of 24 to terminal nodes invoke bit depth.

  • IMAQ flatten image for the 64-bit version of string


    I noticed customer odd based on vision "flatten image chain" on labview 64-bit edition. In my program I use flatten image to the string (with compression to JPEG and kind of flatten Image) to compress and send data to another application. I noticed on the compressed image color missmatch. I say red (255,0,0) 32-bit RGB image and I flattened for string and then save this string as a binary JPEG using Write to vi. When I open the file of the picture is blue (0,0,255). It doesen't matter how data is written (big endian, little endian or native) the result is always the same. 32-bit edition Labview, the code worked correctly.

    I reported a bug in the NC and I'm still waiting for a solution to this problem.

    LabVIEW: labview professional development system 2010 32/64 bits (with vision development module) completely v10.0f2 lie

    Systems: labview 64 bit on windows 7 64 bit-> flatten image to string-> false color

    LabVIEW 32-bit on windows 7 64 bit-> flatten image to String-> colors OK

    LabVIEW 32-bit on windows 7 32 bit-> flatten image to String-> colors OK

    A picture of the block diagram that I used to test the conversion is attached.

    See you soon

    Hi 3DVision.

    I think I see the problem... you code looks like he expects that out of "flattening the image of the chain" will actually be a JPG file as a string, because you have chosen to use the JPG compression options. However, this is not the way that VI is intended to be used. It is simply a way to convert an image type of Vision in a string representation which can be easier to haul around (for example via the network, the user file format, etc.). It is a parallel to normal 'flatten' that can be used on any type of data from LabVIEW. The format of this string is the owner and has provisions for storing information that is specific to the Vision images that cannot be represented in the file formats normal image (overlay information, benchmarking, custom, etc. data info). If you are save the string flattened in a file and expects to open as a normal JPG file, it is unlikely to work properly. The only way that it would be guaranteed to work is if you switch to the corresponding VI "unflatten chain. I don't know why it works in 32-bit mode, but it sounds like a lucky fluke.

    For your use case, you probably want to use the VI "IMAQ write the string. This does not give a result string that is identical to the specified file format.

  • At work, in Adobe Acrobat Standard XI, how can I retrieve or convert a PDF image into a JPEG image?

    December 26, 2014

    At work, in Adobe Acrobat XI - current Standard of Document conversion, to article 6 - export all Images, I clicked on this option, and it took me to a registration screen where a JPEG option came.  When I clicked it, and clicked on the desktop, he said:


    "Adobe Acrobat".
    Acrobat cannot extract all the images in this document (my. PDF document).  Only the images that contain bitmap or raster data can be extracted.

    I've tried several others in Adobe Acrobat Standard XI so trying desperately to be "save under" or convert to JPEG options but nothing allows you to convert my PDF to a JPEG image - and I have 10 of these images to try to convert then why nothing works for me in Adobe Acrobat Standard XI?  Can what preferences or options I change or put in order for that to work in Adobe Acrobat Xi Standard?  What exact measures I can take to fix this problem, because it drives me crazy?

    Export of images n ° USE FOR YOU, for the reasons he explained in the message. Forget it...

    I expect the Save as options to be there, but it is perhaps not in Acrobat Standard. It should be under file > save as > Image.

  • When using an accept custom attribute on an input file his show all files rather than the files that I choose (accept = "image/jpeg, image/gif, image/png, image)

    Hi, I am trying to use the entry of the file accept to limit the type of file that the user can choose when downloading a file. in fact, I have two problems that I can't understand our:

     1. If i am using the value "image/*" its limit the user to all the images but if i am using a custom
         limit e.g. "image/jpeg,image/gif,image/png,image/bmp" its show all the limits in the select box but the
         default value for ths user is "All Files". In Chrome and IE10 its working as needed.
     2. When i am trying to limit to "swf" files using the value "application/x-shockwave-flash" its show "All Files".
         In Chrome and IE10 its working as needed.

    I use Windows 7.

    Thank you.

    Well, it seems you do what it says in the documentation:

    Firefox actually allow you to drop a folder that is not on the list? In other words, is the problem of acceptance is ignored, or that the filter does not display the dialog box?

  • How to save multiple JPEG images in a single file

    I scanned 22 photos (1800 KB total) and I need to transfer all of them for a job application.

    The problem is, when I'm on the job site and I hit the icon of the file attached, I can only select one file.

    The site will only allow a single file transfer only.

    So, is it possible to save all jpeg in jepg files one file, so I can send them into a single file?

    What email program are you using? If you used Windows Mail for example, you could highlight all 22 JPEG files, and then drag them into the text box of a new message and they will settle.
    You can put all the JPEG images in a single folder and then right-click | Send to | Compressed (zipped) folder and attach that. The recipient would save the file and then right-click | Extract all.
  • Why "Windows Live Photo Gallery" open automatically every time I have save a jpeg image?

    Whenever I have save a JPEG of a website for Windows Live Photo Gallery automatically opens.

    This has only started happening recently. How can I stop too?
    I went to options and clicked the 'open Windows Live Photo Gallery after importing files' option, but it still appears.
    It seems to only be with jpeg images.

    Hello Michael,

    Has probably had a modified default parameter. To do this: go to control panel and select default programs. When that opens the first series to select your default programs, when this window opens select Windows Live Photo Gallery in the left column and choose defaults for this program on the right side. When this window opens, make sure that the JPEG is not selected. Save your changes and then OK yourself.

    And to the home page by default, select programs associate any type of file or Protocol with a program. When this window opens to scroll to the bottom of the left side of the window until you get registration .jpeg. If the default associated program isn't one you want, go to top right and click on change program... When this window opens, either select a program from the list, select one of the other list of programs, or click Browse and select the program in the Explorer style list that is offered.

    Let me know if this solves the problem for you.

    Kind regards


  • Cannot open jpeg images in my email. They are deformed with a grey block.

    Cannot open jpeg images in my email.  They are deformed with a grey block. I see only a tiny portion of the upper part of the image.  Tried to save the image on my disk hard but could not be opened.  For example: If the size of the image, I'm saving about 800 K, I'll save the image (that I can not open) in a folder on my hard drive.  When I check the properties of the image, it is much smaller, around 8 or 9 K.  Spent an hour on the phone with HP, but couldn't find a solution.  When starting my computer in Mode without fail and go to my email account, I can see the full image.  Would appreciate suggestions in deca a system recovery.  Thank you

    Hi Larry,

    Cannot open any jpeg full image. I'll help you with this problem.

    1. have you made changes on the computer recently?

    2. what security software is installed on the computer?

    3. are you able to open any image with other file extensions?

    4. what application you use to open the images?

    As you can see the full image in safe mode, let's try the following steps.

    Method 1.

    A clean boot to test if any element of service or third party application startup is causing this issue.

    How to troubleshoot a problem by performing a boot in Windows Vista or Windows 7:

    Note: Once you have finished troubleshooting, follow step 3 in the article to start on normal startup.

    Method 2.

    You can also try disabling the firewall and check if that helps.

    Turn the firewall on or off Windows:

    Note: You should not turn off Windows Firewall unless you have another firewall enabled. Turning off Windows Firewall may make your computer (and your network, if you have one) more vulnerable to damage caused by worms or hackers.

    Method 3.

    You can run the Microsoft Safety Scanner to make sure that the computer is virus-free.

    Microsoft safety scanner:

    Warning of Security Scanner: there could be a loss of data while performing an analysis using the Microsoft safety scanner to eliminate viruses as appropriate.

    LR 5.7 cannot find my files already edited because I accidentally deleted them. I have original and exported raw files edited JPEG images on an external hard drive. How to get back on LR the possibility to repeat already published photos complete with a history of editing? Thank you.

    Thank you Joe Maniac.  I deleted the original linked files on my internal hard drive which were dng files, but had copies of the raw files edited and edited the exported raw files (in JPEG format).  I don't have copies of dng files.  So what I ended up having to do was import the original raw files which then made a DNG copy on my internal hard drive.  The link has not changed, but now the files were back in the original track for missing photo alerts disappeared and I was able to see my change history.  The process has been painful, but without the dng, I had nothing to do a link to more if at least re-import them files has recreated the dng.  I don't know if there was an easier way, but it seemed that the problem did not the link deletion.  I use LR for a few years, but it was a rookie mistake, precipitated by my hard drive being so jammed up I ended up delete what I shouldn't.  I should have just moved the dng and the link to an external hard drive. Thanks again.

  • Cannot open jpeg image

    I use Adobe photoshop 7.0 and usually when I open a jpeg image it just opens but some jpeg images will not open correctly. There is this image to jpeg when I try to open it it either displays an error message that it is not the right type of file or shows a dialog box, as if I'm trying to open a new blank page custom and wonder what size, transparency, etc. and no matter what I select always opens a blank page and I couldn't see the image that is supposed to be there. In other programs, it will open normally and show normal jpeg image in the image viewer or GIMP image editor but curiously won't open in Adobe Photoshop. I tried to open the same file in the GIMP image editor and open the file but when I try to save the file, strangely he advises me to export the file before you save it. I think that the jpeg file may have the invisible layers that photoshop can't handle, but I could not get rid of the layers correctly. I tried to flatten the image and to export the file to a normal jpeg file and remove all the invisible layers, but even after all this, when I save it as a normal jpeg file and open it again in adobe photoshop it still cannot open the file. Anyone know how I can force the program to display the image and or get rid of it permanently from the weird layers or markers that prevented it to open in Adobe Photoshop?

    Thank you for your help Nancy. Your process worked almost completely. The exception is that when I tried to copy the image to a Web page as Firefox (I have not internet Explorer), it became not the Adobe Photoshop Clipboard and therefore could not be pasted. However, I simply recorded the image of a Firefox window as a different file name and that solved the problem. Now the copied image can be opened in Adobe Photoshop. Thank you for your help.



  • Export to PDF error - cannot read a jpeg image, but I do not know what jpeg image.

    I created a (A5) document in Indesign cs6 with 116 pages. Because I would like to print the book I want to export it in pdf format. Normally it is no problem for me, but now, I got the following error message: "error occurred during playback of JPEG images. Image may be damaged or incompatible. Re-save the image with different settings, and then try again. "It's pretty boring, because my book contains 631 links, most of which are .jpg. Anyone know how I can know what image gives the error?

    What is remarkable is the following. Because it is a very large file, InDesign automatically cut into paragraphs (with names like 'A5 V' or 'A5 V3'). Closer to the problem, I tried to export each paragraph (all between 3 and 30 pages) in pdf format. But I managed to do that, then you would think that there is nothing wrong with the document at all. But when I try to export the document as a whole still once I always get this error message on the JPEG image. It takes a few minutes (between 30 and 40 percent of export) before I get the error.

    Is that what I should have tried that I forgot? I hope someone can help me with this problem.

    If you are able to export as sections it is almost certainly not actually a problem with the image, but a problem not enough system resources to complete the work. It's not uncommon that large complexes PDF exports.

    Try to restart and then immediately open ID and try again the first thing of the export. If it works fine. If this isn't the case, you can combine your sections in a single PDF file in Acrobat Pro.

    I think that the problem is due to the version of gcc. It seems that inDesign SDK is outdated.
