Steps to rotate a jpeg image selected from an HTML input field and then convert it into a base64 string

My current project involves using Angular to display an HTML image file. I have access to the EXIF data and am looking for a way to rotate the image client-side based on this information. Right now, I am saving the image as a base 64 string but need to implement a method for rotating it within the browser.

Answer №1

Here is a guideline to achieve this:

  • Start by obtaining the image from an input source
  • Proceed to write the image on Canvas
  • Rotate the canvas as needed
  • Export the modified image

You can check out a practical demonstration of these steps: image rotation example
Remember to run this on a server environment (e.g., using the serve module) for canvas security reasons


Hopefully, this information proves helpful.
