Show HN: Canvas engines performance comparison – PixiJS, Two.js, and Paper.js

“My understanding is canvas also applies AA the rectangle lines still look AA just at a higher DPI. It looks to me like the rectangles done in WebGL are drawn at the scaled resolution (1920 x 1080) vs the unscaled resolution (3840 x 2160), whereas the canvas is DPI aware and…”

Show HN: Canvas engines performance comparison – PixiJS, Two.js, and Paper.js

“FWIW the code in the post doesn't use sprites. I think it is done intentionally because not all of the engines support sprites. As someone mentioned in this thread if PixiJS would use sprites, it could be 10x faster.”

Benchmark: snapDOM vs html2canvas

“Yes, the default capture output is a svg dataurl. But there many other export options. This lib was made as an internal tool for another project called Zumly that is zoomable engine and the svg format was the faster output I found. But then I realized that could be an…”

Benchmark: snapDOM vs html2canvas

“For the 1st example, snapdom is not only faster, but actually correct, while html2canvas has some artifacts (on Linux/Firefox)”

Show HN: Nexus.js - Fabric.js for 3D

“Ha, that brings me back trying to make Fabric.js somehow usable for a 3D viewport at a startup I was working at a while ago. (We used esm.js instead of WASM for the 3d engine, to give you an idea) It was a lot of wrangling and unexpected behavior, and we ultimately ended up…”

Rough.js: Create graphics with a hand-drawn, sketchy, appearance

“I used it to implement the "Sketchify" generator in Boxy SVG ( ). It is especially nice that Rough.js has very few dependencies and can run inside a web worker.”

Consider option to remove blank space around signature

“I need to use the sig image later in my app and the blank space around the sig can be a bit of a pain. I added an option to remove this blank space so that the image returned when I get the data is the cropped signature. I'm not sure if this would be useful to others, and I am…”

Capturing biometric data with the sign

“Hello. Is it possible to get biometric data associated to the sign? I say, writing speed, number of lines, etc. I need to be sure that the user doesn't reject the authenticity of his own sign for legal purposes. This component is the only one I've seen that writes a smooth sign,…”

Pixelorama snap

“Hi! I saw that someone ( probably @Schweini07 ) already registered the "pixelorama" name in the snap store. This is great! I have already a working snap version of pixelorama 0.6 and I would like to share it with you so you don't have to [waste your time reinventing the wheel](…”

High CPU Usage

“Hello, i notified that the Pixelorama eats 2 cpu cores while in idle completely. I have a laptop with Intel Core i7 7600U (2 Cores - 4 Threads) running Fedora 31. Pixelorama is permanently at 50-60% in htop, for comparison the godot editor at only 5%.”

License

“Sorry for reopening this issue. But could you please reconsider the right license option for this? As such this work is good and your option for LGPL allows commercial usage. However, given the LGPL v3 nature that user be given a choice to replace the module with any other…”

SVG and PNG files won't validate in Illustrator and InDesign respectively

“Hi, this is an amazing tool and I'm excited to use it. I'd like to be able to modify the output however Illustrator and InDesign won't open the files citing validation issues. W3C markup validator suggests there's no character encoding declared at the document level. Help? thank…”

Two.js

“Text is actually pretty tricky in WebGL. Lots of ways to do it, all very dependent on your application. I think it would be better to keep it out of the library but allow plugins/etc to compose easily with the rest of two.js. Maybe the author could utilize some npm modules to…”

Two.js

“You can do quite a bit with "circles and squares". Two.js focuses on Path drawing and has robust SVG interpretation for complex vector shapes. I've found the portability to be fantastic. For instance runs svg on iOS and canvas on Android. Two.js makes it simple to run either on…”

IAN library and OpenClipart symbols can no longer be inserted.

“It worked fine in 2.8.1, but testing with the 3.x branch, it no longer works. Interestingly, the smiley and logo demo images still work fine. Is there something that needs to be changed in SVGEdit, or in the external libraries? Thanks!”

Chrome is unusable when selecting lots of paths

“Open SVG-edit with the SVG file pasted below and then drag-select a bunch of the paths. You can see that Chrome has a hard time rendering the select boxes and keeping up with the mouse. No similar problem exists in Firefox which keeps up just fine. # Features”

Vtracer: Next-Gen Raster-to-Vector Conversion

“> Comparing to Potrace which only accept binarized inputs (Black & White pixmap), VTracer has an image processing pipeline which can handle colored high resolution scans. tl;dr: Potrace uses a O(n^2) fitting algorithm, whereas vtracer is entirely O(n). What is the Big-O of the…”

Vtracer: Next-Gen Raster-to-Vector Conversion

“TIL about from "Comparison of raster-to-vector conversion software" which does already list vtracer (2020) visioncortex/vtracer: Vector graphics Rotoscoping: Sprite (computer graphics) E.g. pygame-web can do SVG sprites; so that you don't have to do pixel art and sprite scaling…”

canvg: JavaScript SVG Parser and Renderer on Canvas

“Hey all! The first commit is almost 10 years old now but many are still finding a use case for our canvg library, which takes an svg string and renders it on a canvas. We just released v3 which is a complete rewrite in TypeScript and support for OffscreenCanvas as well as…”

Support for elements

“_From [[email protected]]( on August 05, 2010 14:25:18_ As requested by an SVG-edit user [1], it would be nice to have support for elements. Thanks! [1] _Original issue:”
