Convert Svg To PNG Javascript

As UXD you have quite a lot of scope to influence scalability. The most important steps you can take are to minimise the number of HTTP requests (client latency AND server load) and the size of the data returned (latency and band both across the internet and within your server network and between your (micro)services). To achieve this from the UI the important point is to reduce the amount of UI state (e.g. content) that you need to retrieve as follows bine requests - for example ask for page-able batch APIs from the server API rather than a one-by-one API maximise your smart markup - use Javascript (e.g. ) and CSS behaviour especially within a single-page application cache well - use HTTP cache headers cache request state (e.g. objects from HTTP-served JSON) press well - minify your JS don your JSON gzip your HTTP use scalable in multiple sizes serve in SVG and use a HTML canvas to convert to PNG in the browser Doing any of the above will make a big difference - doing all of them will make your app stand head-and-shoulders overpeting apps.

If you are looking for a web solution for visualizing large dataset without installing any apps D3 and other svg output based visualizing libraries will fail to give you performance. Problem with such libraries is due to the fact the svg DOM elements eat too much of RAM. As a result even on being served on robust servers these apps hog on the client's RAM like a leech ultimately causing DOMs to break or the browser to crash. A better alternative is Canvas based libraries or if you are good at basics JS and PHP itself can be coded for canvas. Good point is Canvas itself is treated as single DOM and hence single page code hosted in minimal ram server can host good apps if client dont have very low RAM (nothing works at low RAM). Except that there is a possibility that canvas will still run on such low RAMs. PLUS there are opotions to convert them to PNG one is ( Canvas2PNG s ) library. Cons are canvas isnt vector. So if you at some point think that you need to resize your chart you have to recode and believe me its much longer coding than svg. Several JS library based on canvas. 1.
