Invert Alpha

A Simple Plugin to Invert the Alpha Channel



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.

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

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

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));

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.
