MadJik Posted December 4, 2011 Share Posted December 4, 2011 Donut distortion Effect Plugin What's this? It would be more handy if I can find some good math skills to help me with sinus & co. formulas. Don't hesitate to PM if you like to solve my problem! I'm not really happy with this distortion effect as I've not find the correct formula to apply what I had in mind. But for now it gives some good results enough to be published. How does it works? The initial idea was to distort the image by a rotation between 2 circles and so create something like a Donut aspect. This is to illustrate the idea: The red Arc should be the distortion of the green segment. The result for now is just a distortion between 2 circles... and I named it the Donut effect! Before: After: I've found 4 modes of distortions: This is a test of the modes on lightrays: Download the DLL Plugin Donut.dll Here is the DLL The MadJik's All plugins package is available ! http://forums.getpaint.net/index.php?showtopic=7186 How to install Close Paint.net Classic version of Paint.net Unzip and (re)place the DLL in your Effect folder usually: C:/Program Files/Paint.NET/Effects Microsoft Store version of Paint.net Unzip and (re)place the DLL in your Effect folder usually: /My Documents/paint.net App Files/Effects/ You have to adapt for your language My Documents The User interface This plugin is added to the menu Effects, submenu Distort. External radius (0,1000, dft 300) Set the size of the donut by choosing its radius. Internal radius (0,1000, dft 100) Set the size of the hole of the donut. Unit (checkbox, dft unchecked) unchecked: External and internal raduis values are in pixels checked: The values are in 1/1000 based on the smallest size of the selection. - ex: for a 800x600 image, 1000 represents the full raduis of 600 = 300px This is usefull to redo the effect over the image with a small selection here and there: Distortion angle (-360,+360, dft 10) This value is issued to set the "strength" of the distortion. Quality Increasing the quality is slowering the rendering a bit, and should reduce the pixelisation. Effect Mix This is a slider to mix the final image with the orignal image to make the effect more or less subtile. Mode Choose the distortion mode (Soft, medium, hard, distroy).
