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)

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?
