QUESTION

Why is my gaussian blur approximation half strength?

Asked 2021-May-21 at 06:28

I've implemented the stackblur algorithm (by Mario Klingemann) in Rust, and rewrote the horizontal pass to use iterators rather than indexing. However, the blur needs to be run twice to achieve full strength, comparing against GIMP. Doubling the radius introduces halo-ing.

...

ANSWER

Answered 2021-May-21 at 06:28

Note that what you have implemented is a regular box filter, not stackblur (which uses a triangle filter). Also, filtering twice with a box of radius R is equivalent to filtering once with a triangle of radius 2*R, which explains why you get the expected result when running blur_horiz twice.

Struggling to upload my node.js application to azure

First, make sure what services you use, AWS or Azure Web App Services ?

Whatever services you use, I recommand you use git to deploy your web app.

You just make sure your web app can run successfully in local. And the port you use like app.set('port', process.env.PORT || 3000); or const port = process.env.PORT || 3000. Which means you can success run in local with 3000 port.

For more details, you can see my answer in another post.

You can refer to the way of troubleshooting when deploy web app by Action. Hope my answer can help you.

How to include "require" in PhpStorm for my JavaScript code?

Asked 2019-Aug-09 at 19:53

I am using the line canvg('canvas', svg); in my code. This means I need canvg.js.

I have included canvg.js in my html header. However it gives me an error that "require is undefined".

For those that don't know the first two lines of canvg.js are:

Answered 2019-Aug-09 at 19:53

Simple answer is that the file you have included is not supposed to be run in browser, as it uses the CommonJS syntax that can only be used in server-side code run by node.js.

You have to make sure to include the browser version of your library that doesn't have any require() calls, like:

Upgrading Webpack from 2.7 to 4.35 blank page IE11

Asked 2019-Jul-15 at 12:12

I'm working on a project where I want to update the Webpack 2.7 config to the newer 4.35 for optimization and cleaning purpose. I rebuild from scratch my configuration, works on every browser (Firefox, Chrome, Edge) but not IE11. No error in the console, a blank page.

I'm using SASS, SCSS, CSS, JS and Vue

I tried to use the previous configuration but I have to update to many things and I failed to compile in the end. I try not to upgrade every package but only Webpack and the ones that needed to upgrade for compatibility purpose. I also already tried Vue-CLI as it's a Vue project, but same issue. I needed to rewrite every predefined configuration to work for my project...

canvg SVG rendering to wrong format

Asked 2019-Mar-21 at 14:30

I have a piechart with labels and legend which looks fine in SVG but as soon as I use canvg to transform it to canvas some formats are missing / get wrong. SVG:

Canvas:

I already inline the CSS to apply all CSS settings but still the format does not match.

Any ideas? Is this a (canvg) bug or am I doing s.th. wrong?

ANSWER

Answered 2019-Mar-21 at 14:30

Basically it was a combination of lack knowledge and a bug.

First of all, all relevant CSS styles have to be inlined when using canvg. Second, there was a bug in canvg using tspans and text-anchors.

Here is the (more or less) working code:

SVG to Image export performance issues (using canvg / XMLSerializer / getComputedStyle)

Asked 2019-Mar-06 at 09:57

I am using canvg to convert a chart svg to an image. We have the issue that by default not all CSS attributes are applied to the image so we ended up using getComputedStyle in a loop.

This is a total mess under performance aspects if we have 10 or even 20 charts to be exported at once.

Answered 2019-Mar-06 at 09:57

I have managed to solve the performance problems of exporting C3 SVG charts to PNG by avoiding to use getComputedStyle.

Browsing the issues in C3 I found issue #313

https://github.com/c3js/c3/issues/313

For others http://www.nihilogic.dk/labs/canvas2image/ might also be a good place to look at but I found a solution at https://gist.github.com/aendrew/1ad2eed6afa29e30d52e#file-exportchart-js-L29.

I have changed the code from using angular to d3 and now it works (for me).

Hopefully this might help others having the same issue.

Here the working code. Please note: the css styles are only examined and inlined once.

Your PDF is A4 size; which is 595 x 842 (considering it as 72 PPI). But your image Canvas is 600 x 450. That creates issue. Try reducing the Canvas size passed to doc.addImage method. Like,
