Invert Alpha

A Simple Plugin to Invert the Alpha Channel

  Download

 

Invert Alpha is a simple plugin that inverts your Alpha Channel based off of your set tolerance. This plugin is most useful when dealing with transparency gradients, creating alpha masks, and more. To use this plugin, simply extract the zip file to your Effects folder and restart Paint.NET. Then go to Adjustments-> Invert Alpha. Toying with the tolerance is recommended to discover some more interesting uses for this plugin.

Your first real plugin! Hurrah!

I expect Liquefy next

[Mike Ryan]

Dont hold your breath to long

Also, I want to give my thanks to Pyrochild for helping me out with this basic plugin.

Don't say that - people will think it's another prank!

[Mike Ryan]

Lol, then I also want to say this is NOT a prank.

Also, thanks to BoltBait for publishing Code Lab and making my first plugin possible :wink:

Thus giving the further impression that it is, in fact, a prank.

Good plugin, mostly I just use a transparent gradient, I don't really change it around, but congrats on the plugin.

[Simon Brown]

I look forward to seeing your plugins in future.

[R3VENGE]

nice plugin i look forward to seeing more of your works

[Truelove]

Very useful with HDR lighting...

This is CodeLab code:

Enjoy!

[Mike Ryan]

TrueLove, while it is a basic plugin I would prefer that the source to any or all of my plugins be distributed solely by me. But I am glad that you enjoy using this plugin, and I hope it is a good start for future plugins from me.

[Truelove]

Sorry if something going wrong, I've just wrote this source by myself to recreate your work. That's will not happen again.

[Mike Ryan]

Not a real problem at all. And you wrote it exactly as i wrote it, that is why I got confused.

[BoltBait]

If that's true, you have a bug in your code. You should use Utility.ClampToByte in there somewhere...

[Mike Ryan]

...?

What bug? Who is buggin around?

Anyways, this plugin is going to be superseded soon with some extra features. It will be entitled 'Alpha Works' and I wish I could confirm some extra features. Until then, good night to you all!

[Truelove]

I imagine broken brain, when will try to rewrite new "Alpha Works" code...

[Truelove]

Don't know right I'm or not, but this is new Utility.ClampToByte() code:

#region UICode
int Amount1 = 0; // [0,255] Transparensy
#endregion

void Render(Surface dst, Surface src, Rectangle rect)
{
   PdnRegion selectionRegion = EnvironmentParameters.GetSelection(src.Bounds);
   ColorBgra CurrentPixel;
   int R, G, B;
   byte A;
   for(int y = rect.Top; y < rect.Bottom; y++)
   {
       for (int x = rect.Left; x < rect.Right; x++)
       {
               CurrentPixel = src[x,y];
               R = (int)CurrentPixel.R;
               G = (int)CurrentPixel.G;
               B = (int)CurrentPixel.B;
               A = (byte)(int)(Amount1 - CurrentPixel.A);
               dst[x,y] = ColorBgra.FromBgra(Utility.ClampToByte(,Utility.ClampToByte(G),Utility.ClampToByte(R),Utility.ClampToByte(A));
       }
   }
}

I will begin working on Alpha Works as soon as I get some more testing in with IndirectUI.

[Mike Ryan]

Alright, Alpha Works is finished but not compiled yet. I need Code Lab to start behaving correctly and I will make the big upload.

CodeLab is fine. It's your script... Don't use anything but alphanumeric characters in the .cs file name of your effect. CodeLab uses that filename as your namespace... "namespaces" must be alphanumeric without spaces. I have added a note about this to CodeLab's help file.

[Mike Ryan]

Great! Expect an update sometime tommorow (hopefully)
