• Revision 99218 : Signalé par Dut : lorsque l’option de date de création de la fiche est ...

  19 août 2016, par marcimat@… — Log

  Signalé par Dut : lorsque l’option de date de création de la fiche est coché en configuration,
  la page d’édition de profil sur l’espace public affiche des morceaux de code javascript.
  Effectivement, depuis le passage en <div></div> des formulaires SPIP, nos expressions régulières
  de capture peuvent se planter encore plus qu’avant, vu que ça en cherche par défaut qu’une
  fin de . Et il peut y en avoir plusieurs dans le bout de code qu’on souhaite capturer.
  Ça se voyait moins avec les , moins présents dans les saisies de formulaire.
  Ici, non seulement la saisie date peut générer des <div></div> internes en plus, mais elle a aussi
  du HTML dans du code javascript.
  On se crée donc une fonction qui crée une expression régulière beaucoup plus sophistiquée
  et complexe pour obtenir une balise avec un attribut spécifié, et son contenu interne,
  même s’il contient des fermetures de la même balise.
  Cette fonction pourrait être ajoutée dans SPIP je pense ; après quelques tests tordus,
  elle semble fonctionner.
  Ainsi inscription3_regexp_capturer_balise(’class’, ’editer editer_cextra_creation’, true)
  signifie qu’on recherche une classe ’editer ...’ sur une balise div (par défaut),
  le true signifiant que le nom de classe peut être n’importe où dans l’attribut.
  False est plus adapté à la recherche d’attribut ’id’ par exemple.

• How can I simply replace the colors using the color masks on this image and then save it ? With RGBA channels as example

  31 août 2020, par karl-police

  So I got this GIF here :

  


  

  


  As you can see, it has Red, Green and Blue in it. And it also has a full transparency in it. This was composed together with FFMPEG out of images that looked exactly like that.

  


   

  


  Then, with FFMPEG I "decomposed" the RGB and Alpha channels using the filter "extractplanes".

  


  The gallery of that, in correct order starting from up to down, can be found here :

  I am not sure if this actually helps me or if I'm supposed to decompose them. Because apperantly now, after decomposing them, I'm supposed to modify them, but I'm not really sure how. It's like how do I modify the red channel that only has black and white, so all at the end, will match to the specified HEX color that I want it to be to.

  


   

  


  Now, my question is. How do I exactly make the color changing happen ? Can I do this simply with JavaScript ? Is it possible to do with FFMPEG, if possible without ImageMagicks ? Maybe a programming language where not much installation is needed to do that ?

  


  What I understood is that. These channels basically contain values from 0 to 255 with black and white. I think the "brightness" is that what 0 and 255. So something inbetween, would be like grey.

  


  So basically, like we do (255,0,0) for red. In these channels, if I want red somewhere I need to put one fully white pixel on the red channel and on all the other channels, there has to be a fully black pixel.

  


  That's the concept. Now is the question, how can I do this ?

  


   

  


  At the end I want to make it look like the colors this one has, as example :

  


  

  


  This is from a game. So basically that's how it looks like in the game. And the game files only use these RGBA template sprites.

  


   

  


  I asked a similar question here : How to change colors of an image using RGBA and more channels independently of their color

  


  But somehow, I might didn't seem to explain it that well.

  


   

  


  I made a thing here to test around with things. I guess that's nearly close, but the lines are kinda weird. jsfiddle.net/qsgazubk

  


• I cannot play a mp3 file on Discord's voice channel using discord.py

  1er décembre 2024, par ra1ned

  I am creating a discord bot that plays lofi for me. It does not play a song for me even though it shows a green indicator on a voice channel.

  


  Here's what I've written :

  


  if message.content == "!join":
    await message.author.voice.channel.connect()
    await message.channel.send("Successfully connected")

if message.content == "!play":
    if message.guild.voice_client is None: 
        await message.channel.send("use !join")
        return
    
    await message.channel.send("playing a song rn")
    print('*** playing a song rn')
    
    message.guild.voice_client.play(discord.FFmpegPCMAudio('lofi.mp3'))


  


  I put FFmpeg.exe and lofi.mp3 in the same directory as this script.
Also, it is strange that FFmpeg does not return any exception nor output on console although it seems to have failed to load the file. I have seen people who had the same problem, but it seems like that they get some error messages, unlike me.

  


  Here's the output on console after using !join

  


  2024-12-01 16:59:39 INFO     discord.voice_state Connecting to voice...
2024-12-01 16:59:39 INFO     discord.voice_state Starting voice handshake... (connection attempt 1)
2024-12-01 16:59:40 INFO     discord.voice_state Voice handshake complete. Endpoint found: japan8946.discord.media
2024-12-01 16:59:40 INFO     discord.voice_state Voice connection complete.


  


  after using !play, it only displays the message I wrote :

  


  *** playing a song rn


  


  Can someone help me with this ?
