Convert base64 for use with rect.fills imageHash

The Plugin API says that images should be converted to Uint8Array.

Thank you. I realized I was trying to do the conversion inside code.ts but it needs to happen in ui.html. In ui.html I’m using a helper function to convert the base64 string.

  function _base64ToUint8Array(base64) {
    var binary_string = window.atob(base64);
    var len = binary_string.length;
    var bytes = new Uint8Array(len);
    for (var i = 0; i < len; i++) {
      bytes[i] = binary_string.charCodeAt(i);
    }
    return new Uint8Array(bytes.buffer);
  }

hey you have any idea about this error “figma_app.min.js.br:5 unhandled promise rejection: Error: in set_fills: Expected “fills.[0].imageHash” to have type string but got undefined instead”
im giving uint8array for imagehash

You should have passed a Uint8Array as an argument to the createImage method. This method will return an Image object in which you can get the value of the hash property and use this value to set the fill.

I want to note that in Figma there are methods for encoding/decoding Base64.

Hello,

I’m currently developing a Figma plugin that converts Figma frames into HTML and CSS code. However, I’m facing challenges when it comes to generating responsive CSS for each node within the frames.

I would love to know if anyone has experience or solutions for dynamically generating responsive CSS for individual Figma nodes, such as handling different screen sizes, layout adjustments, and element resizing/positioning based on Figma’s design constraints.

Any tips, best practices, or resources would be greatly appreciated!

Thank you in advance!
