Tips for cropping an image using CSS with dimensions specified for width, height, and x and y coordinates

As I work on implementing a cropping feature using react-easy-crop, my goal is to store the user's image along with pixel coordinates that dictate their preferred cropping area.

My objective is to utilize the parameters provided by react-easy-crop in order to crop the banner image for display on a user's profile.

The use of react-easy-crop, which relies on react-image-crop, involves the following parameters:

{ width: integer, height: integer, x: integer, y: integer }

Applying CSS style:

I am seeking guidance on how to use this data to render a cropped image using CSS.

(While aware of alternative CSS cropping methods, I specifically aim to utilize the aforementioned data.)

Implementing Javascript approach:

I have made attempts to convert the Image URL into a blob or base64 format for cropping purposes, but encountered CORS errors when dealing with images hosted on Azure blobs. Instead of tackling security concerns, I would prefer a solution that leans towards CSS implementation.

Answer №1

Welcome to the world of coding! I stumbled upon these 2 interesting articles that might be helpful:

Based on my research, it seems like setting width and height with CSS alone isn't possible. The workaround is using HTML like this:

<img src="assets/images/image.png" width="50" height="50">

One suggestion from G-Cyrillus is utilizing the object-fit property.

In terms of X and Y adjustments, you can experiment with padding-left: 5px and margin-left: 5px. Remember, margin affects the outside while padding influences the inside.

I hope this information proves useful for your coding projects! Happy coding!
