To convert a base64 image to a blob image in Ionic, you can use the atob() function to decode the base64 string into a binary string, then create a Blob object from it. Here's an example:

// Convert base64 image to blob image

const base64String = 'your base64 image string';

const byteCharacters = atob(base64String);

const byteNumbers = new Array(byteCharacters.length);

for (let i = 0; i < byteCharacters.length; i++) {

    byteNumbers[i] = byteCharacters.charCodeAt(i);

}

const byteArray = new Uint8Array(byteNumbers);

const blob = new Blob([byteArray], {type: 'image/jpeg'});

Now you have the image data in a Blob object, which you can use as needed in your Ionic app.
