In the question title you write about string conversion, but in the question you talk about binary data (picture) so here is a function which makes a proper conversion starting from PNG picture binary data (details and reversal conversion are here). This answer is based on the original code and DOES NOT include updates to that code posted in other answers here. Approach 1: Using Download attribute The download attribute simply uses an anchor tag to prepare the location of the file that needs to be downloaded. Do US public school students have a First Amendment right to be able to perform sacred music? so the solution to the deprecation warning on web JS, use window.btoa First thing that comes to my mind - try to render your image to SVG (using domtoimage.toSvg), then render it yourself on canvas and try to play with that canvas' resolution somehow.It's probably possible to implement such feature as some kind of rendering option in the lib itself, so you can pass image dimensions in pixels. Image Generation typically takes 2-5 seconds in Phantom, in my experience. Based on the code proposed by Joe Dyndale and as suggested in comment by Marius, it is possible to improve the performance with IE7 by constructing the result with an array instead of a string. Unreserved characters have no such meanings. NOTE: There is a known issue, that this will not work with SVG. Render HTML 2022-09-16 15:18:34 1663312714. Even when the HTML inside the SVG exceeds the size of the image it wil draw onto the canvas correctly.

Directly from Mozilla, two nice functions for this purpose. What does "use strict" do in JavaScript, and what is the reasoning behind it? The is_dst parameter has no effect when using non-pytz timezone implementations. I fixed the encodeURIComponent part but the nested object part still holds true. This isnt a problem if youre actually treating the string as a byte array, but if youre trying to do something else then youll have to encode it first. or if possible can you please re-write it? body If you write encodeURIComponent(",") in your JavaScript console, then you will also get %2C. The sets of reserved and unreserved characters and the circumstances under which certain reserved characters have special The characters allowed in a URI are either reserved or unreserved. Maybe this is supposed to not work, but at least I'd like to understand why then. I just made it more readable and made methods marked as private in the comments in the original actually be private by using the revealing module pattern. i didn't test and won't test it :). By this example, you can now see your image in
tag where id = 'real'. To trigger a file download on a button click we will use a custom function or HTML 5 download attribute. JavaScript URL encoding normally replaces a space with a Object But it often encodes what online decoders cannot decode! with "5 is close to what you are looking for, but it's somewhat convoluted. And with decodeURIComponent You can also quickly check a character's hexadecimal equivalent with: $ echo -n , | xxd -p 2c Share. How do I remove a property from a JavaScript object? When the migration is complete, you will access your Teams at stackoverflowteams.com, and they will no longer appear in the left sidebar on stackoverflow.com. It's used to convert strings to base64 any non-drunk coder would have called it. This question and its answers pointed me in the right direction. Sets or returns the behaviour of the background and border of an element at page-break, or, for in-line elements, at line-break. Have you come across anything that operates faster than PhantomJS? forEach undefined Run it and zoom in with your browser to see that the resolution does not diminish as you zoom in. -S, --show-error Show error. Try with different scalings. Take a screenshot of a webpage with JavaScript? I try to use this function and I receive the error: Caused by: org.mozilla.javascript.EcmaError: TypeError: Cannot find function replace in object teste teste teste I'm trying to encode .txt with "teste teste teste". The following reference topics provide you with more information about controlling access to your IoT Device Provisioning Service. Grants delete access to the device registration status. This is MUCH better than html2canvas. It works, but these variables will overwrite any existing ones with the same name outside this function. -s, --silent Silent mode. Non-anthropic, universal units of time for active SETI. It was fixed by replacing such references with "Base64": You can use btoa (to Base64) and atob (from Base64). And then you can use a PDF to image tool like imagemagick. Error InvalidCharacterError: The string to be encoded contains characters outside of the Latin1 range. In this article. Conversely, if is_dst=False the time would be interpreted as 2:30 standard time (equivalent to 3:30 local time). This determination is dependent upon the rules established for reserved characters by individual URI schemes. Do any Trinitarian denominations teach from John 1 with, 'In the beginning was Jesus'? You are right. JavaScript I have rewritten these encoding and decoding methods by hand with the exception of the hexadecimal one into a modular format for cross-platform / browser compatibility and also with real private scoping, and uses btoa and atob if they exist due to speed rather than utilize its own encoding: https://gist.github.com/Nijikokun/5192472. The Service API is used to retrieve registration state and remove device registrations. Same as the Headless Chrome Screenshot solution, with the exception of considerable contribution to global warming. If you use code from webtoolkito info do not forget about copyright: /** * * Base64 encode / decode *, All that is needed to make it safe for most binary encoding/decodings it to remove the questionable, @Marius: I'm wondering why they would they even include. With -s, make curl show errors when they occur Grammar and types And I added a little extra feature: a checkbox so that you can make the PNG-image transparent if you like. How can we create psychedelic experiences for healthy people without drugs? This is also useful when the base64 encoding is non-standard; in my case the "/" character wasn't used, and the "?" cburgmer.github.io/rasterizeHTML.js/rasterizeHTML.allinone.js, https://www.chromestatus.com/feature/5706745674465280, http://www.freakyjolly.com/convert-html-document-into-image-jpg-png-from-canvas/, https://html2canvas.hertzen.com/dist/html2canvas.js, Making location easier for developers with new data primitives, Stop requiring only one assertion per unit test: Multiple assertions are fine, Mobile app infrastructure being decommissioned. Content=-Type Why is there no passive form of the present/past/future perfect continuous?
