exifdata | write JPEG EXIF metadata in pure JavaScript | Base64 library

On my iOS app written in Swift I need to take pictures and save them on gallery; as Apple documentation, all the pictures are taken in landscape also if the phone is in portrait; if we save the picture as-is it will be saved 90° rotated.

The question: How can I correctly manage the device orientation when saving picture?

Thank to some searches I used this solution:

I am able to upload images using Uppy on my react app:

Upon selection and upload of an image, I see a preview of the image, along with options to remove it, add more, etc.:

After clicking the "Continue" button, the state of reporting (from const [reporting, setReporting] = useState(false);) is set to true, which I think triggers a re-render of the DOM, including the disappearance of the UploadManager component, which contains the Uppy dashboard pictured above. Now, instead, a component is rendered:

I am trying to use filepond for my assignment, but I can't get exifdata from photos.

for example, as I expected

Iam trying to execute an exif command using subprocess. The command is :

I'm fairly new to React and currently working on a project that uses exif-js library to read image EXIF data, see sample code below. EXIF.getData(file, callback) is the method from this library for reading the given image and performing some other tasks in the callback. In my component, I defined a function (doSomething) to be used by the callback. But when I try to call the function this.doSomething(), it throws error: this.doSomething is not a function.

In their documentation, they explained that In the callback function you should use "this" to access the image..., so it looks like this is being used to refer the file inside the callback, that's why there is no such method on the file object.

So question is: how do I call my other functions in the same component, if this is referring to something else in the library callback?

I'm building an Electron app that manages a collection of photographs on an NAS. That NAS has two logical volumes, named "alpha" and "beta". For reasons I want to understand (and fix!), my app gets an ENOENT error whenever it tries to run CLI tools against files on beta, but not when it runs CLI tools against alpha. Additionally, it is permitted to perform regular FS operations (e.g. readdir, stat, even rename) against files on both volumes without error. For example: the app first learns about the files on beta because it scans the filesystem using find; that scan succeeds.

I'm using the CLI tool exiftool to extract image metadata from all these files (e.g. dimensions, capture device, etc). Here's the command my app runs, using child_process.spawn:

My view controller opens a directory, counts the file types therein and stores the results in a dictionary [String:Int] of filetypes and count. I have a TableView that displays this.

The first time I open a directory the ViewController correctly displays the information in the FileTypeTableview. If I try to open another directory, execution gets to the line:

XPComment and XPKeywords does not appear when writing exif metadata.

I am running Python35 in windows 8.

I have a python script that obtains exif metadata from typical jpg image files. It is seen to 'work', but runs into a 'no such file or directory problem' whenever I type a new filename into the script.

For example - I place two images 182830.jpg and 182833.jpg into my directory C:\Python35\Scripts

My python script (which I grabbed from stack-exchange and tinkered with to make it work - shown below) is also placed in the same directory, and this script will actually run properly from the IDLE editor for Python35. Or at least, the script will run when first applied to the image file '182830.jpg'
