It’s only useful for very tiny images. Base64 encoded files are larger than the original. The advantage lies in not having to open another connection and make a HTTP request to the server for the image. This benefit is lost very quickly so there’s only an advantage for large numbers of very tiny individual images.
I found a solution for my issue: Bitmap bImage = newImage; // Your Bitmap Image System.IO.MemoryStream ms = new MemoryStream(); bImage.Save(ms, ImageFormat.Jpeg); byte[] byteImage = ms.ToArray(); var SigBase64= Convert.ToBase64String(byteImage); // Get Base64
‘Faster’ is a hard thing to answer because there are many possible interpretations and situations: Base64 encoding will expand the image by a third, which will increase bandwidth utilization. On the other hand, including it in the file will remove another GET round trip to the server. So, a pipe with great throughput but poor … Read more
The Node btoa() and atob() functions are the only ones that have been deprecated. However, if you’re working on the DOM code (front-end) and see this deprecated notice, you can use the window object to get around it. window.atob() For more info
The following functions will achieve your desired result: var base64result = reader.result.split(‘,’)[1]; This splits the string into an array of strings with the first item (index 0) containing data:image/png;base64 and the second item (index 1) containing the base64 encoded data. Another solution is to find the index of the comma and then simply cut off … Read more
Latest and greatest way to do this: Node supports file and buffer operations with the base64 encoding: const fs = require(‘fs’); const contents = fs.readFileSync(‘/path/to/file.jpg’, {encoding: ‘base64’}); Or using the new promises API: const fs = require(‘fs’).promises; const contents = await fs.readFile(‘/path/to/file.jpg’, {encoding: ‘base64’});
I try to avoid text only answers; including code is best practice but the question about storing images comes up frequently and it’s not really covered in the documentation so I thought it should be addressed at a high level. Generally speaking, Realm is not a solution for storing blob type data – images, pdf’s … Read more
Heres a function. Can’t remember where I got it from. Public Function EncodeFile(strPicPath As String) As String Const adTypeBinary = 1 ‘ Binary file is encoded ‘ Variables for encoding Dim objXML Dim objDocElem ‘ Variable for reading binary picture Dim objStream ‘ Open data stream from picture Set objStream = CreateObject(“ADODB.Stream”) objStream.Type = adTypeBinary … Read more
If you set content-type to image/jpeg, you should give just the jpeg data, without the base64 crap. But you’re treating the result as if it was html. You’re effectively building a data uri, which is ok, but as you noted, only as an uri. So leave the content type as it is (text/html), and echo … Read more
It’s not possible bit-by-bit but 3 bytes at a time, or multiples of 3 bytes at time will do!. In other words if you split your input file in “chunks” which size(s) is (are) multiples of 3 bytes, you can encode the chunks separately and piece together the resulting B64-encoded pieces together (in the corresponding … Read more
