#an-image-element-id Play with image base64 encode CSSĬreate a “url” with a base64 encoded data for “background-image” attribute. Passes a base64 encoded data directly into “src” attribute via a data URI. The following is an example of data URI of a base64 encoded image: data:image/png base64,iVBORw0KGgoAAAANSUhEUgAAAAQAAAADCAIAAAA7ljmRAAAAGElEQVQIW2P4DwcMDAxAfBvMAhEQMYgcACEHG8ELxtbPAAAAAElFTkSuQmCC HTML The second part: a base64 encoded string of the image.The first part: declare a base64 encoded image.A data URI is split into 2 parts separated by a comma: Simply embed a data URI into a HTML or a CSS file. In the experiment, base64 solution is the winner. With a large image, web browser need to wait for the whole base64 coded stream before rendering below elements.įig 2 : In, the author did an experiment to compare size and transportation of small images (16x16) between binary files and base64 encoded strings.This requires more transportation on the wire, which might be exceptionally painful on mobile networks. Base64 encoding data is bigger than their original binary representations roughly 33% in size.Embedding base64 encoded images in CSS files is much more simple than using sprites.Especially, it is extremely effective for small images. Base64 encoded images help to reduce number of HTTP requests.So it is suitable to embed a base64 encoded image into an XML document or an email message.

However, we may need to store base64 encoded strings into somewhere such database in order to present them on a web dynamically.ĭetail of how to embed an image with base64 encode can be found at Online Image To Base64 Converter Pros and cons In other words, base64 encoded image data is packaged in HTML or CSS payloads. Specifically, we will embed image data directly into HTML or CSS files by base64 encoded strings instead of declaring URLs to image files. In fact, there is a completely different way to display images on a web without any extra HTTP request for image files, called displaying images with data URI. Working with PowerShell and WPF makes me realize that *this* is what I always wanted coding to be.Fig 1 : The above figure demonstrates that a web browser makes 3 different HTTP requests for 3 resource files. $thisistheimage.source = $bitmap Show form Take note in the XAML as to where the variable name was taken. $bitmap.EndInit() Freeze() prevents memory leaks.

The code contains comments that explains each step. Note the image being used in both the popup and the notifyicon itself:īelow is the simplified code I used to display the icon within my application popup. Here's what it looks like in my application. I knew base64 would be the answer, and ultimately, some C# code from StackExchange helped me figure out what needed to be done. I plan to share it, and wanted to use a non-standard icon, but didn't want to require a separate download. I'm currently building a notification module to let me know when VMware vCenter alerts go off in my home lab.
