QUESTION

React - unable to use `this` to call component methods in callback function

Asked 2021-Jun-13 at 23:19

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?

You need to bind this of the class to the doSomething handler. This can be done in the constructor

Indicates that you're trying to load Xdebug twice. One time successfully so that it shows up in php -m, and one time with the wrong path, which gives this error. You need to find the wrong line in all of the ini files that are being loaded. You can find all the ini files that are being loaded with php --ini.

More efficient method to take picture from Android in-app-cam and upload it to server

Asked 2021-May-22 at 08:28

I'm building an app that require method to take picture from in-app camera, but for some Android devices (old device or low ram), it's quite freeze when taking picture triggered. Is there any code i can modify or optimize to make user experience feels better?

...

ANSWER

Answered 2021-May-22 at 06:28

In general, I would advise you to step through your code and look at large memory resources you're generating on each line and consider setting those to null aggressively as you move throughout the method if you're done.

For example, you have a variable called temp which is size "Y" bytes that you appear to rotate and then never use temp after that. If picture is a rotated copy of temp then you have now used 2Y bytes of memory to keep temp and picture. I suspect if you simply set temp to null after creating picture, you might free up half that memory that your older/slower phones are going to badly need.

Take that same concept and follow through with the rest of your method to see if you can find other optimizations. Basically anywhere you're creating a copy of the image data you're not going to use, you should immediately set it to null so the garbage collector can throw it away aggressively.

Your composer.json already lists symfony/symfony as a required package. This contains symfony/mime - as long as you are using Symfony v4.3 or later. The MIME component did not exist before that.

How to write orientation data with exifinterface directly to image buffer (or rotate the image itself)?

Asked 2021-May-11 at 09:32

I'm taking images using the Camera2 API.

As far as I understand, if the device is rotated during image capturing, you can set the corresponding rotation to the jpg file using the exifinterface. However, I do not store the image to a file, but rather send the image buffer - which I receive from the capture request - directly to a remote client via LAN:

For JPEG images:

Use the CaptureRequest directly and set the value for the tag JPEG_ORIENTATION according to the devices orientation. I simply used the display rotation, since only values of 0, 90, 180, 270 are allowed anyway:

On an Android 11 device the OS is very picky concerning extensions.

You can create .jpg, .png and .webp files in DCIM directory and maybe other image files.

But not .tmp files as they are no image files.

So you are victim of the ExifInterface programmers.

If they had decided for .jpg.jpg and not for .jpg.tmp you would not have this trouble.

File an issue/report.
