In addition, how to get Base64 data from HTML5 canvas?
get base64 data canvas The canvas in HTML5 has a method called toDataURL () that you can call to turn a HTML5 canvas into a PNG image and to get the image data of that canvas. By default it will give you a base64 representation of the image in PNG format. In simpler terms: you will get a PNG image but it has been encoded in base64.
Similarly, how to convert a Base64 image into an image file? The first solution that you may implement and probably the only idea that will occur to everybody, when you need to upload a Base64 image into the server, is to upload this file as a string and then convert it to a file in the server side.
Consequently, can a PDF file be displayed as a Base64 string?
Just for the record: pdf.js is able to display PDF files encoded as base64 strings. Maybe the problem of @kakaluote444 is that the string itself was buggy.
And, how to get the image data from canvas?
To get the image data URL of the canvas, we can use the toDataURL () method of the canvas object which converts the canvas drawing into a 64 bit encoded PNG URL. If you'd like for the image data URL to be in the jpeg format, you can pass image/jpeg as the first argument in the toDataURL () method. Base64 Encoding of canvas Easy to use.
