How to print an iframe with base64 data?

Printing an iframe with base64 data can be done by first converting the base64 data into an image, and then printing the image. Here is a step-by-step guide on how to achieve this:

1. Retrieve the base64 data from the iframe: Get the base64 data from the iframe source using JavaScript. You can access the iframe content using the contentWindow property and extract the base64 data from it.
2. Convert the base64 data into an image: Use JavaScript to convert the base64 data into an image. You can do this by creating a new Image object, setting its source to the base64 data, and then drawing the image onto a canvas element. var canvas = document.createElement('canvas'); var ctx = canvas.getContext('2d'); var image = new Image(); image.onload = function() { canvas.width = image.width; canvas.height = image.height; ctx.drawImage(image, 0, 0); }; image.src = 'data:image/png;base64,' + base64Data;
3. Print the image: Once the image is created, you can print it using the window.print() method. This will open the print dialog allowing the user to print the image. window.print();
4. Clean up: After the image is printed, you may want to remove the canvas element from the DOM to clean up. document.body.removeChild(canvas);

By following these steps, you can print an iframe with base64 data in your web application.
