• Evolution #4658 (Nouveau) : Améliorer la classe .offscreen

  11 février 2021

  Bonjour,

  Ayant eu un cas où la classe n’avait pas caché complètement un border à un élément, j’ai cherché comment on faisait de manière moderne et accessible.

  Fichier à modifier : https://git.spip.net/spip/dist/src/branch/master/css/clear.css#L74

  Méthodes : https://webaim.org/techniques/css/invisiblecontent/#techniques

  Donc, il faudrait remplacer la méthode actuelle par :
  

  <span class="CodeRay"><span class="class">.offscreen</span> {
      <span class="key">position</span>: <span class="value">absolute</span>;
      <span class="key">left</span>: <span class="float">-10000px</span>;
      <span class="key">top</span>: <span class="value">auto</span>;
      <span class="key">width</span>: <span class="float">1px</span>;
      <span class="key">height</span>: <span class="float">1px</span>;
      <span class="key">overflow</span>: <span class="value">hidden</span>;
  }
  </span>

  ou plus moderne :
  

  <span class="CodeRay"><span class="class">.offscreen</span> {
      <span class="key">clip</span>: <span class="error">r</span><span class="error">e</span><span class="error">c</span><span class="error">t</span>(<span class="float">1px</span>, <span class="float">1px</span>, <span class="float">1px</span>, <span class="float">1px</span>);
      <span class="key">clip-path</span>: <span class="error">i</span><span class="error">n</span><span class="error">s</span><span class="error">e</span><span class="error">t</span>(<span class="float">50%</span>);
      <span class="key">height</span>: <span class="float">1px</span>;
      <span class="key">width</span>: <span class="float">1px</span>;
      <span class="key">margin</span>: <span class="float">-1px</span>;
      <span class="key">overflow</span>: <span class="value">hidden</span>;
      <span class="key">padding</span>: <span class="float">0</span>;
      <span class="key">position</span>: <span class="value">absolute</span>;
  }
  </span>

• ffmpeg add scaled logo with two outputs

  24 février 2020, par yellowmn

  I want to add a scaled logo with 2 outputs.

  For 1 output this works for me :

  -filter_complex '[1:v]scale=156:94,overlay=main_w-overlay_w-10:10'

  But it does not work for 2 outputs in one ffmpeg command.

• Running PowerShell command in Universal Windows Platform C#

  6 juin 2017, par stephen

  So I am trying to write a basic application to cut and export a subsection of a video. I have come across (and decided to use) the FFMPEG command line tools to do the cropping. This seemed straight forward (https://stackoverflow.com/a/5047426/6728859), but Universal Windows apps do not support System.Diagnostics.Process. Instead, it was suggested that they do support Powershell, which means I could do it by following (https://blogs.msdn.microsoft.com/kebab/2014/04/28/executing-powershell-scripts-from-c/). However, I get the following errors

  Cannot find type System.SystemException in module CommonLanguageRuntimeLibrary

  Cannot resolve Assembly or Windows Metadata file 'System.Configuration.Install.dll'

  From my limited understanding System.SystemException was removed in UWP, and I’m not sure where to find System.Configuration.Install.dll.

  Now to get PowerShell I had to include System.Management.Automation which I got from C:\Program Files (x86)\Reference Assemblies\Microsoft\WindowsPowerShell\3.0 which doesn’t seem correct to me, but I could be wrong.

  Is it possible to run commands in a UWP, or does anyone have any suggestions ?
