Unerase ?


Recommended Posts

I understand that the eraser tool sets a layer's alpha to zero. Is the image information discarded at this point, or is there a way to unerase? Some sort of "paint on alpha" tool would be cool. Sorry if this has already been discussed. I tried to search, really :-)

No sorry, this isn't possible with our toolset. While it's true that the eraser simply works on the alpha channel, we don't have a tool for setting the alpha channel to 255.

Although a CodeLab script to do this is trivial:

void Render(Surface dst, Surface src, Rectangle rect)
{
   for(int y = rect.Top; y     {
       for (int x = rect.Left; x         {
           ColorBgra c = src[x, y];
           c.A = 255;
           dst[x, y] = c;
       }
   }
}

I drew some red brush strokes, erased it all with the Eraser tool, and then this script "restored" the stuff I'd just "hidden."
