Loading an image in QImage sometimes has the wrong rotation

I am loading an Image into QImage - to say - the camera - but sometimes the Rotation is not correct.

Any way to solve this problem?

Yes, but it is nowhere near as easy as it should be.

Basically, you need to use libexif to read the properties of rotating the image, then use the QTransform to spin to the correct orientation.

This patch usually appears when I did the search for examples on how to do and seems to pretty much cover the process:

  • My incoming mail has the wrong date and time on this subject. How can I fix it?

    incoming mail has the wrong date and time when they arrive in my Inbox.

    The timestamp on an e-mail comes from two places, time on the mail server settings and the settings of the time on your PC.  This time setting includes the current time, the time zone and setting time summer time.  If one of them is off, the timestamp will be wrong.  You can check on your PC, but not those on the mail server.

  • Home App has the wrong address for my house

    I am creating a location of automation in the Home app on iOS 10. The problem is that this app and only this app, does not show my house to the right place.

    My contact card has the right address it and maps shows my house to the correct place. Home app shows a marker a few blocks away and I don't know where he is from this place, because I can't find any way to change the address of a House HomeKit.

    In addition, address location automation search does not at all. He suggested addresses in places ranging from nearby towns to the country across the ocean, but nothing for the town that I live.

    If this had happened to me, I remove and re-add my house such as described here (bottom):

  • Cannot get rid of loaded xml image scroller when navigate off the page.

    I have a thumb wheel loaded xml that stays on the screen when I leave the frames where it exists.

    This is the upward I tried to solve this problem. It has been suggested that I put a mc on the frames with the scrolling of the image and call it dummy_mc.

    Then I put the code on frameworks that are not supposed to have thumb scroller:

    dummy_mc. Visible = false;

    function removeScrollerF2(e:Event=null):void {}

    If (scroller) {//prevents a problem if you were to use the same navigation code after having removed the scroll}

    scroller.removeEventListener (Event.ENTER_FRAME, moveScrollerThumbs);

    removeChild (scroller);

    scroller = null;  If, when you want to create your clipping, it does not need to be re-created, delete this line of code.

    }

    trace ("dummy2_mc works on null");

    }

    dummy_mc.addEventListener (Event.REMOVED_FROM_STAGE, removeScrollerF2);

  • saved file has the wrong timestamp

    I have Dreamweaver MX2004 installed on two PCs, both have this problem... (the two Win XP home sp3)... When I save a file with DW time is 2 hours before my system clock. Even if I just upload (FTP) a file with good time... She is replaced to 2 hours in advance. I find this curious y at - it a setting or tweak somewhere? It only occurs with DW.

    PLEASE IGNORE MY PREVIOUS ANSWER. THE HIDEOUS JIVE FORUM SOFTWARE ALLOW ME TO CHANGE IT.

    Upon further research, it seems logical (not a bug because it works as expected) in the behavior of timestamp in MX 2004 that changed in later versions of DW (from v.8)

    http://kb2.Adobe.com/CPS/400/kb400972.html#how_dw_determines_change

    «So that Dreamweaver MX 2004 knew for some distance and local files were identical, Dreamweaver MX 2004 set the local timestamp to match remote timestamp after each put or get.» This led to a question of ease of use, since now, you don't really know when a file has been updated locally. Dreamweaver 8 changes is no longer the local file date/time stamp to match the distance of time after putting / if then it will reflect the local time, when the file last saved. »

    I'm afraid I don't see any way to change this behavior without upgrading to CS4. I don't see Adobe issuing a patch for MX 2004, given that the code has been created at the time when Macromedia owned DW.

  • Siri on mac has the wrong person as "My Info".

    Just finished macOS installation of Sierra and Siri works very well except that he thinks I'm my daughter. When I ask "who am I?", he gets it wrong and shows the map of my daughter. When I ask about me, it shows my card (even marked as "self") as if I was just another contact.

    I checked in the Contacts app and I'm correctly identified on 'my profile', nothing special on the daughter card.

    I can't find a way to change the card associated with 'my info' as you can in settings of Siri on iOS.

  • How to load an image stored in the database to the point of the Image

    Hi all

    Please help me to load an image to an element of the image, the IMAGE is stored as BLOB in the database.

    Please give me the code to load that image into the next key element based on certain conditions as employee number should correspond with the identification number of the photo.

    Thanks in advance.

    If you have a table with a column of type blob and some identify and want to show this blob content as a picture in a form?

    -Create a new block based on this table, make sure that the element type of the blob column is image.
    -In the key-nextitem (or another location where you want to upload the image), put something like:

    GO_BLOCK('IMAGEITEMBLOCK');
    SET_BLOCK_PROPERTY('IMAGEITEMBLOCK', ONETIME_WHERE, 'ID=' || varContainingTheIdValue);

  • I asked firefox to block an image on my blog, but firefox has blocked all images on the blog, there are no images in posts, pages, the theme, each image have been removed from the blog. Is it possible to restore the images.

    Hi, I was working on my wordpress blog that uses the theme "Intrepidity". I wanted to remove a header image I added to the header but could not find a way to remove, so I click right for an option. the option I took was "do you want firefox to block the image? I clicked Yes, and this is the last time I saw a picture on the blog. Firefox has deleted all the images in the blog, even the side bars are gone, the header is not more, every single photo on the post, pages disappeared. The blog is just a shell now. Is there a way I could have restored the blog images. This is the name of the blog:
    http://www.weightlosscontrolreviews.com/

    With the display site, click the site identity button (for more details about what it is to see the How do I know if my connection to a Web site is secure? article), and then click more information. This will open the page info dialog box.

    First, select the permissions tab, make sure that 'Load the Images' is set to allow (default selection should work as well)

    Then select the media tab, and then click the first item in the list. Use the down arrow key to scroll the list. If any element has the option 'Images of block of (field name)' selected, deselect the option.

    This should hopefully solve your problem, but see also the problems that cause to not show images.

    Some add-ons can also block images, for example, if you have AdBlock Plus installed, make sure that you have not accidentally created a filter to block images.

  • VDM 2012 Algorithms.MatchPattern2 SP1 has the image of the model

    My application requires (acquisition and treatment) fast enough repetitive image<100ms per="" cycle).="" kind="" of="" "realtime"="" processing,="" i'd="" prefer="" not="" doing="" post="" image="">

    Currently the image processing takes ~ 200ms per cycle (mainly grey filtering image).

    ~ 150ms of this time is taken by load images from disk or cloning model images of the model (using the flatten/unflatten visionimage).

    The reload or cloning is that the Algorithms.MatchPattern2 has the image of the model during execution, i.e. I have to reload or clone images model each acquisition/processing cycle.

    Ideally, configuration I would like to provide 1 x set of images of model for processing application that is reused (without cloning) each treatment cycle to a time of 50ms ~ process.

    Patches or a workaounds?

    Thanks for the reply Rob.

    Note: I use .net VDM and coding in c# libraries.

    My purchase is decoupled from my transformation. The main reason to mention the acquisition should provide a bit of context to my question.

    I first thought that my large KING was originally the processing time increased (initial duration process = ~ 230ms). Then I reduced the sizes of my Kings and improved the execution time = ~ 190ms.

    I am currently creating a model images table and passing to the function (essentially by 9 x 1 x OCR and correspondence to the model) image processing.

    When I remove the model image cloning code (visionimage flatten/unflatten), the image processing function runs in 50-60ms but runs only once. On the second cycle of the excution, it throws an exception.

  • How can I determine the type of image to be used before loading an image?

    I'm developing an application using VB 2005 which measures two 8-bit or 16-bit image files. When I saw the picture, I find that I have to set the type of image the image buffer before playback of the image in it. For example, if I read a 16-bit image in a buffer of 8 bits, the image is truncated. I guess I could read the image in a 16-bit buffer and retype it if the pixel values are less than 255.

    Is there a better way to do it? Can I determine the number of bits of an image before loading in a buffer?

    Thank you!

    Hi Steverino,

    Olivia is incorrect... VDM has a function called GetFileInfo which does just what you want. It only reads the header of the image but does not load the entire image in memory. It will give you various properties such as the bit depth.

    I think that on the new .NET support, there can exist here: NationalInstruments.Vision.Analysis.Algorithms.GetFileInformation.

    Thanks to the ICB and our legacy of .NET support, it's probably a similar name.
