imagedata | Unified method of retrieving an ImageData instance | Runtime Evironment library

What you need is data in your imageData from the frontend and use resize function in sharp module.

Here's an example on how to resize the image to 150 pixels in width:

When you configure your photo settings originally, request a preview image by setting the previewPhotoFormat. Now you will be able to get the photo's previewCGImageRepresentation and now you are in a world of pixel data that you'll be able to deal with.

According to the MDN, createImageData doesn't copy the image data from the buffer.

imagedata An existing ImageData object from which to copy the width and height. The image itself is not copied.

You don't need to create a separate imageData anyway;

Let's break down the error message:

• Thread 1: Exception:

  An Objective C exception was thrown from Thread 1 of your program (that's probably the main thread). Not particularly interesting/insightful.

• -[AVCapturePhotoOutput capturePhotoWithSettings:delegate:]

  This syntax describes the Objective-C method that threw the exception. The method's selector is capturePhotoWithSettings:delegate:, and it belongs to the AVCapturePhotoOutput class. The - indicates that it's an instance method (where a + would have indicated it's a class method).

• If you specify a non-nil format dictionary in your settings ...`

  This is the case, you called capturePhoto(with: settings, ... with settings that aren't nil.

• your delegate must respond to the selector captureOutput:didFinishProcessingPhoto:error:

  The system is complaining that you passed a delegate that does not respond to the selector captureOutput:didFinishProcessingPhoto:error: (In Swift, the method is imported as photoOutput(_:didFinishProcessingPhoto:error:)).

  That is, your delegate doesn't define any methods with that name. You decided to pass self (whatever that is, I don't know without context) as the delegate: capturePhoto(..., delegate: self).

  Whatever the type of self is, it already conforms to the AVCapturePhotoCaptureDelegate protocol (or else this would never have compiled). But it does not implement this method, which is optional by the protocol, but mandatory in this context.

• or the deprecated captureOutput:didFinishProcessingPhotoSampleBuffer:previewPhotoSampleBuffer:resolvedSettings:bracketSettings:error:

  This is just telling you that instead of captureOutput:didFinishProcessingPhoto:error:, you could instead fix this issue by implementing captureOutput:didFinishProcessingPhotoSampleBuffer:previewPhotoSampleBuffer:resolvedSettings:bracketSettings:error:, but since that's deprecated, you probably shouldn't use it.

So in all, whatever the type of self is, you need to make sure it implements the method photoOutput(_:didFinishProcessingPhoto:error:)

Unlike context.getImageData(), gl.readPixels() reads pixel data starting from the bottom-left corner, not from the top-left corner. You can apply a transformation on tempCanvas and draw it onto itself after putting the image data like this:

Try this if it helps

Rather sending formdata and slug to vuex attach slug to formData like that

When adding "late" to a variable, you guarantee which variable will be initialized, so it makes no sense to compare it to null, because it can never be null. If you compare a variable with "late" without having initialized an exception occurs.

In your case, the best option is to use a bool variable to monitor progress.

Support for SVG is a new feature of Microsoft Office 365. That's why it is not fully supported by apache poi until now (May 2021, apache poi 5.0.0).

To implement that support in Excel one needs to know how Excel inserts SVG images. It converts the images to PNG for backwards compatibility. And it puts both, the SVG image as well as the PNG image, into the workbook. Then it shows the PNG image as a shape in the drawing. That shape has an additional reference to the SVG image, so if Excel 365 is used, the SVG image can be got too.

To implement that support in apache poi following is needed:

1. A SVG to PNG converter. There Apache Batik Transcoder can be used.

2. An extended XSSFWorkbook which provides either a separate addSVGPicture method or provides support for SVG in addPicture method. But extending XSSF... classes is not as simple as it could be, because of some weird decisions to make members or methods private.

3. A XSSFRelation.IMAGE_SVG to provide creating relations while creating pictures and shapes. But XSSFRelation is not extendable at all. So extending the low level POIXMLRelation is needed.

4. An extended XSSFPictureData to provide support for needed picture constructors for the new POIXMLRelation.

Following code provides all that. It is commented where needed.

In the function processPhotosRequest there is a mapping from FlickrPhoto to Photo objects which is done so the data can be stored in Core Data but it is not those objects that should be returned so the row
