It automates a bunch of steps that I make when fixing landscape pictures. It is obviously not right for everything, but I find it useful. Hopefully you will too.

Download the Landscape.dll as part of my plugin pack here: https://forums.getpaint.net/index.php?/topic/32048-v

If you have trouble installing this plugin, post your troubles here.

Enjoy. B)

For those that are interested in such things, here is the CodeLab source:

I really like this plugin.

BoltBait is there any way to have a tilt option for the horizon line? sometimes the horizon just isn't smack dab across the screen in straight line.

the work around I've been using is larger canvas and rotating the image then applying plugin then re righting the picture. not absolutlely ideal. but only way I can think to do this. is there another method I'm not thinking of?

In CodeLab:

1. CTRL+I and click on Update (the selected control)

2. Replace the original code: 

AdjustmentPixel.R = Utility.ClampToByte(NewR);
AdjustmentPixel.G = Utility.ClampToByte(NewG);
AdjustmentPixel.B = Utility.ClampToByte(NewB);

with 

AdjustmentPixel.R = Int32Util.ClampToByte((int)NewR);
AdjustmentPixel.G = Int32Util.ClampToByte((int)NewG);
AdjustmentPixel.B = Int32Util.ClampToByte((int)NewB);

Since you created CodeLab in the first place, could you teach me how to apply two effects in a plugin? I'm working on a HDR plugin and I'm trying to add a "Brightness/Contrast" effect to it before the "Gaussian Blur" effect - but I seem to get errors. Any tips and help?

Where can I find the "download " for this landscape -Plugin? I lost all my plug ins when I HAD to upgrade from Windows7 to W10. I could not find the plug in paks I used when I first  Downloaded Paint.net. I am trying to find them all.  Why is everything changing making it a daily hourly search? Any help would be appreciated. Thanks 

Here is one of my Designs. It is Day 6 of the creation, and God has just created the Elephant, the male and his female. I love art work. Paint.net is the Best tool on the market. I really need my Plug -ins.
