Reflective Objects and Text

[KevinTunis]

How do you create reflective objects and text in v 3.0?

[trickman]

this should be moved in General discussion.

You can use the gradient plugin in order to create a reflection.

Flip what you want to reflect.

Move it to the correct position.

Set colors ALPHA to: Primary: 255; Secondary: 0

Use the gradient plugin with alpha only checked.

You can use the gradient plugin in order to create a reflection.

For 3.0 there is the Gradient tool, hehe...

(I still use the plugin when I don't want to worry about "drawing" the gradient)

Here is what I want to do. I have been testing different ways to do this and none have been successful so I thought I might just come back here and ask. I have an image of a server with a white background; normally what I would do is save it as a gif and make the white background transparent. In Paint.NET, I am not sure how this is done or what would be my best option. Than I would create my banner, in this case I wanted to gradient the color from a navy blue to a black at the bottom. The white background would then become the blue to black background; the server would than reflect in the black portion of the background. Could anybody take me through the steps to accomplish this?

Kevin Tunis:

what you could do is selc all the white (the backround) and then use the gradient tool. When you have something selected, paint.net only lets you work on that selection. I hope this helps, i didn't really understand what you want to do though.

Use the codelab for that:

Cut the shadow first, and delete remaining blue pixels...

Tada!!!!

Humm! I would like to use this effect but i don't know how to use a codelab so i must to wait for the BolBait's dll

munchkinmann, can you use the image that MadJik created and explain how you select the white background and gradient this background from navy to black?

MadJik, can you tell me more about codelab and how to install/use it?

[MadJik]

Well! CodeLab is a plug-in here:

http://paintdotnet.12.forumer.com/viewtopic.php?t=1096

I'm not the one to explain CodeLab. It uses C# programming language.

The Code for reflection is here:

Read the topics behind this links... This is from where I started...

Madjik ? It doesn't work ! The .cs into the samples folder included in codelab zip work fine but not the code for reflections made by Boltbait . However i have followed the instructions but nothing happens...

[MadJik]

This is the code is used:

void Render(Surface dst, Surface src, Rectangle rect) 
{ 
   int depth = 100;    // maximum distance of the reflection 
   int MaxAlpha = 128; // darkest reflection (255-0, default 128) 
   int ignore = 0;     // bottom pixels of object to ignore 

   PdnRegion selectionRegion = EnvironmentParameters.GetSelection(src.Bounds); 
   Rectangle selection = this.EnvironmentParameters.GetSelection(src.Bounds).GetBoundsInt(); 
   ColorBgra CurrentPixel; 
   for(int y = rect.Top; y < rect.Bottom; y++) 
   { 
       for (int x = rect.Left; x < rect.Right; x++) 
       { 
           if (selectionRegion.IsVisible(x, y)) 
           { 
               CurrentPixel = src[x,y]; // Get the current pixel 
               if (CurrentPixel.A == 0) // is it transparent? 
               { 
                   int y1=0; 
                   int yd=0; 
                   for (y1=y; y1 > 0; y1--) 
                   { 
                       if ((y1 != selection.Top) && (src[x,y1].A == 0)) 
                       { 
                           yd++; 
                       } 
                       else 
                       { 
                           break; 
                       } 
                   } 
                   if (y1+1-yd-ignore >= 0) 
                   { 
                       CurrentPixel=src[x,y1+1-yd-ignore]; 
                       if (CurrentPixel.A > 0) 
                          if (yd                           { 
                              // fade the reflection out 
                              CurrentPixel.A = (byte)((MaxAlpha/depth)*(depth-yd)*CurrentPixel.A/255); 
                          } 
                          else 
                          { 
                              CurrentPixel.A = 0; // totally faded at this point 
                          } 
                   } 
               } 
               dst[x,y] = CurrentPixel; 
           } 
       } 
   } 
}

I just changed paremeters Depth = 250 and MAxAlpha = 255 for this server!

Open CodeLab and Copy/paste this code.

Important !

The background must be transparent.

(White or Black will also be "reflected").

PS: DLL for this code is now available here...
