Selection/non Selection Bottom

[moc426]

I want to draw on the last row ( 5 pixel height ) of an image or image selection.

Why does this always return true, when looping thru rect?

    for(int y = rect.Top; y < rect.Bottom; y++)
    {
        for (int x = rect.Left; x < rect.Right; x++)
        {

if ( y > (rect.Bottom - 5) )

Paint.NET runs effects in multiple threads, and to do that it slices up the source surface into a whole bunch of thin strips. rect is only giving you the bounds of one of those strips. To find the size of the whole selection use the Rectangle returned by:

EnvironmentParameters.GetSelection(***).GetBoundsInt()

//*** needs to be the bounding rect of the whole source surface, but getting that value will vary depending on what overload of the Render() method is being called. For CodeLab, use src.Bounds

Hey bud, thanks for the information!
