ANSWER
Answered 2022-Mar-23 at 12:46what exacly would you like to change? which property?
you can use map method and iterate thought each array item and change there any property
const newUpdatedArray = array.map(i => ({...i, type: 'new type', version: Math.random()}))
in my example I changed type and version in each object

I've seen this problem online e.g:

QUESTION
I am building c# contact manager desktop application where you can choose an avatar image from the file and later crop it. The original image is properly displayed after cropping, replacing the original one. However, later, upon attempting to register the account the image appears to be Null with such an error being displayed:
System.ArgumentNullException: „Value cannot be null. (Parameter 'encoder')”
The method for uploading an image to the register page:
...ANSWER
Answered 2021-Nov-15 at 13:51My guess is that the failure occurs due to pictureBoxProfileImage.Image.RawFormat. You just replaced pictureBoxProfileImage.Image, but what rawFormat does a new Bitmap(...) have? While I cannot find any documentation about it, I would guess that it does not have any valid rawFormat at all.
So I would try to either replace it with something like ImageFormat.Png, or save the rawFormat from the original bitmap to use when saving.
QUESTION
I need to be able to use loadFromJSON with canvas resolutions/aspect ratios other than the one that the JSON data was generated at, while maintaining the relationships of the graphic elements and centering everything within the canvas.
I have tried every solution I've seen or have come up with. At this point I don't know if it is my logic that is bad, my arithmetic or my coding.
Functional code is included here (stripped of my failed "attempts"). Only the first function matters – the rest is UI boilerplate and JSON data. Here's a JS Fiddle if that is easier: https://jsfiddle.net/sunny001/a8thqd0z/24/
Details: I save the JSON data with custom width and height properties so that I know the resolution/aspect ratio the data was created at. I then use those properties to determine how to scale things. The canvas is always set to the size of the window, which can vary. I've seen some solutions which use the canvas "zoom" property but I can't do that because the app allows the user to zoom in on the documents they are annotating.
Background This is for a desktop electron app where the user can annotate text documents, so accurate positioning matters. The user can create and present the annotations in a window mode or full screen.
ANSWER
Answered 2021-Feb-17 at 21:34Finally solved this after trying many different approaches (and much anguish).
The gist is to select all objects and then scale and center. A tricky thing is that the first object in my data is an image which all the drawn elements need to stay in register with. So I first correct the image path and then, after the selection has been scaled, I shift the selection to that the image remains centered on-screen.
Looking at the code now, I can see places to optimize it (e.g. since there is only ever one image in my data, there is no need to loop through all the remaining data after the images has been found)

The following code crops a portion of an image. I'd like to get the image data for the cropped area in base64, and I tried to do it using context.toDataURL():
ANSWER
Answered 2020-Dec-10 at 19:26You're attempting to save an image that's been fetched from an external source. CORS does not allow this unless the site the image has been fetched from explicitly has you whitelisted:
For security reasons, browsers restrict cross-origin HTTP requests initiated from scripts. For example, XMLHttpRequest and the Fetch API follow the same-origin policy. This means that a web application using those APIs can only request resources from the same origin the application was loaded from unless the response from other origins includes the right CORS headers.
If you need to save image information, use an image that you have local access to (e.g. from your assets folder or a file upload).
QUESTION
I have a canvas and I am loading this canvas as JSON data. I want it to give me an alert() when it clicks on an empty place except objects on the canvas. How can I do this?
canvas.on('selection:cleared') code works when I add an element to the canvas, but I want it to work on the canvas that I loaded as JSON data.
ANSWER
Answered 2020-Nov-14 at 15:55You can listen to mouse:up and check if there is active object (canvas.getActiveObject()). If not, the point is empty.
QUESTION
I have a canvas and I am loading this canvas from JSON. There are two group elements and they have their own ID (ID: 1047,1048). I keep the ID numbers to be deleted in an array of 1048,1049,1050.
...ANSWER
Answered 2020-Nov-09 at 20:49You can filter the all the objects based on their id, if the id is in the list, remove the item. Like this:

Install cropy
You can use cropy like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
