Sign in to view. Is this on an iOS device the images are being taken? The photo was taken with iphone but I am experiencing this problem in desktop. Is it going to be a case of reading EXIF data manually, or can we expect a fix?

Is there a CSS property? If necessary, this angle is then rounded and normalized as described above for an value. The browser can rotate the image, but the web application needs to give the advice how to rotate this explicitly.
I've written a little php script which rotates the image. Be sure to store the image in favour of just recalculate it each request.
As the previous poster said, you will need to rotate the image itself. That way you will avoid that viewers that do respect the orientation tag will rotate it again. You can then use the JPG files thus obtained in a webpage without worrying about that stuff:. It includes a demo index. Latest Safari Firefox hasn't fully implemented this see Bugzilla issue As for the standard, the image-orientation property is now marked deprecated on the latest CSS Images Level 3 spec draft :.

Is there a way to tell browsers to honor the jpeg exif orientation? Ask Question. Asked 7 years, 8 months ago. Active 2 days ago. Viewed 34k times. I know that the automatic rotation of JPG files is disabled in browsers. They can not enable it because it would break the layout of some websites. Possible workaround is to set the IMG elements orientation style dynamically via script based on preprocessed image file names which contain a suffix to indicate the proper orientation.
But this still require preprocessing. I imagine the response will be in the browser code. I think the best answer is here: stackoverflow. Active Oldest Votes. And then you put the image into the background of an element and boom! Out of the blue it's upside-down or sideways. Even Firefox only gets one of these cases right the img, but not the background : softov.

You can use it on images in the browser, either from an image or a file input element. Install exif-js through NPM :. Then add a script tag in your an HTML in the best position referencing your local file.
As a second parameter you specify a callback function. In the callback function you should use this to access the image with the aforementioned metadata you can then use as you want. You can access it's properties to get data like the image captionthe date a photo was taken or it's orientation.
You can get all tages with EXIF. Or get a single tag with EXIF. The tag names to use are listed in EXIF. Tags in exif. Important : Note that you have to wait for the image to be completely loaded, before calling getData or any other function.
It will silently fail otherwise. You can implement this wait, by running your exif-extracting logic on the window.
Or on an image's own onLoad function. Because it fires before images are loaded. Note there are also alternate tags, such the EXIF. See the source code for the full definition and use. Check the included index. To not slow down this is optional, and you need to call EXIF. This is an open source project. Please contribute by forking this repo and issueing a pull request. The project has had notable contributions already, like reading ITPC data.
Latest commit 53b0c7c Nov 7, Exif is short for Exchangeable image file format. A standard that specifies the formats to be used in images, sounds, and tags used by digital still cameras. In this case we are concerned with the tags standard and how it is used in still images.
This page will show you all the data recorded from your camera when a photo was taken, the camera type, lens, aperture, exposure settings, etc. This lead to the realization that we could parse Exif data while the photo is being uploaded, then expose this to the user while they are editing their photos in the Uploadr before they even hit the Upload button. Why would we need to parse Exif on the client-side, if we are parsing it already on the server-side?
Parsing Exif on the client-side is both fast and efficient. It allows us to show the user a thumbnail without putting the entire image in the DOM, which uses a lot of memory and kills performance. When they drag those photos into the Uploadr, BOOM, we show them the data they have already entered and organized, eliminating the need to enter it twice. Web workers allow us to offload the parsing of byte data into a separate cpu thread.
Then when a user adds an image to the Uploadr we create event handlers for the worker. When a web worker calls postMessage we capture that, check for Exif data and then display it on the page. Any additional processing is also done at this time. Using Blob. The Exif specification states that all of the data should exist in the first 64kb, but IPTC sometimes goes beyond that, especially when formatted as XMP.
I'm trying to reduce images in client side before uploading them to preserve users' bandwidth and storage space in server side, while keeping informations about the original shot. One drawback of this technique is loss of metadata Exifsuch as date and time, position, orientation Extracting exif datas can be done via Exif JS or other library. But I didn't find how to put these informations in the reduced file in canvas object, base64 url or php side.
There is no easy way to do this. There is no mechanism to insert custom or additional chunks into the file format from the browser-side of things. It's possible to do but not just straight forward.
The file format specification will be necessary. An optional, and perhaps better approach in this case, would be to extract the EXIF chunk, format it as a JSON object and send that as meta-data to the server. You just need to make server side "aware" of that it need to consider the meta-data for the image received. The client doesn't get to cause arbitrary events to fire on the socket.
It is always a message event. Using the same client, try this server code in your connection handler: socket. If the height or width of the canvas is 0, the string "data:," is returned. This is most likely the cause for some images to fail to receive a proper dataUrl.
If you don't "override" the loadComponent method then the default component loader's loadComponent will be invoked which only calls the loadViewModel if you've provided a viewModel config option.
In your getConfig method you are returning a config with require which means that your require. Having a Line series: To modify the line thickness, change the series format.
Ie: Chart1. You can use. I don't understand why it would give me two hellos back? Because the first entry in the array is the overall match for the expression, which is then followed by the content of any capture groups the expression defines.
