I will post a tut for it in the next day or so.

For a different type of effect using a similar technique you could also make a polaroid collage out of just one picture like this: Same basic technique, different end effect. sorry about the quality of the picture but I shrunk it down from a larger version so it looks a bit jagged on the edges of the photos, but you get the idea.

My bad. I didnt have that one and I really had thought I had downloaded all the plugins.

Still playing around with the Codelab and thought I would try to create a rainbow effect. Here is what I came up with. Run on just a blank page it will create something like this: But my use for it was to do something like this. Right now it just creates the rainbow as you see it here with the colors stretching vertically down the page. It works for selections as well, but only rectangular ones. It still creates something with weird shaped selections, but it is all screwed up and I cant seem to wrap my hands around how to program around it. Also, if I had more programming experience I would have liked to have set this up like a gradient tool, but at least for now it just does the rainbow. I have set up three selection bars for Red, Green and Blue starting colors. You can create different rainbow effects by playing with the starting colors, but the default settings will give you your standard rainbow (though for some reason the size of the image can affect how far down the color scale it gets. For example on an 800x600 image it seems to stop at light blue, but for a smaller images reaches purple and even sometimes makes it back to red - which was the intent when programming it). Here is the code in case anyone is interested. int Amount1=255; //[0,255]Red Start int Amount2=0; //[0,255]Green Start int Amount3=0; //[0,255]Blue Start void Render(Surface dst, Surface src, Rectangle rect) { PdnRegion selectionRegion = EnvironmentParameters.GetSelection(src.Bounds); // Delete any of these lines you don't need Rectangle selection = this.EnvironmentParameters.GetSelection(src.Bounds).GetBoundsInt(); long CenterX = (long)(((selection.Right - selection.Left) / 2)+selection.Left); long CenterY = (long)(((selection.Bottom - selection.Top) / 2)+selection.Top); ColorBgra PrimaryColor = (ColorBgra)EnvironmentParameters.PrimaryColor; ColorBgra SecondaryColor = (ColorBgra)EnvironmentParameters.SecondaryColor; int BrushWidth = (int)EnvironmentParameters.BrushWidth; int l = 1; int p = 1530 / rect.Right; int r = Amount1; int g = Amount2; int b = Amount3; 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]; // TODO: Add pixel processing code here if (x == rect.Left) { r = Amount1; g = Amount2; b = Amount3; } switch(l) { case 1: g = g + p; if (g > 255) { g = 255; l = 2; } break; case 2: r = r - p; if (r < 0) { r = 0; l = 3; } break; case 3: b = b + p; if (b > 255) { b = 255; l = 4; } break; case 4: g = g - p; if (g < 0) { g = 0; l = 5; } break; case 5: r = r + p; if (r > 255) { r = 255; l = 6; } break; case 6: b = b - p; if (b < 0) { b = 0; l = 1; } break; } // Access RGBA values this way, for example: CurrentPixel.R = (byte)r; CurrentPixel.G = (byte)g; CurrentPixel.B = (byte)b; // CurrentPixel.A = (byte)PrimaryColor.A; dst[x,y] = CurrentPixel; } } } } Thanks to Miguel for showing me the 'switch' routine to use (which apparently runs faster than a bunch of if statements). I incorporated it into this and remembered to add an icon this time. Let me know what you think. here is the link to the plugin http://Spongey437.googlepages.com/rainbow3.dll

I was looking for a way to make vertical or horizontal lines across a whole image (or a selected region) and who knows, maybe this is already out there somewhere but I also wanted to play around with the CodeLab so i thought I would write it up myself. So here is what it will create - Pretty simple, and even with my limited knowledge of programming I was able to use CodeLab to come up with it. The effect has two slider bars. The first sets the width between the lines (defaults to 10, and I maxed it out at 100, minimum is one but that actually just paints the whole page one color). It uses whatever your primary color selected is as the color of the lines. The second slider is just to determine whether you want Vertical or Horizontal lines (1 for vertical, 2 for horizontal). Here is the source code in case anyone was interested - like I said it is a pretty simple code but it might help some new people see how CodeLab works. Thanks to BoltBait for his tutorials on writing CodeLab plugins as well, they were very helpful. Looking at the code below, all it does is check to see if you want it horizontal or vertical. Then it goes through every pixel and calculates whether that pixel is a factor of the width that you have set. If it is, it writes to that pixel, if not it does nothing. int Amount1=10; //[1,100]Width int Amount2=2; //[1,2]X - Y void Render(Surface dst, Surface src, Rectangle rect) { PdnRegion selectionRegion = EnvironmentParameters.GetSelection(src.Bounds); // Delete any of these lines you don't need Rectangle selection = this.EnvironmentParameters.GetSelection(src.Bounds).GetBoundsInt(); long CenterX = (long)(((selection.Right - selection.Left) / 2)+selection.Left); long CenterY = (long)(((selection.Bottom - selection.Top) / 2)+selection.Top); ColorBgra PrimaryColor = (ColorBgra)EnvironmentParameters.PrimaryColor; ColorBgra SecondaryColor = (ColorBgra)EnvironmentParameters.SecondaryColor; int BrushWidth = (int)EnvironmentParameters.BrushWidth; 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]; // TODO: Add pixel processing code here if(Amount2 == 1) { if (x % Amount1 == 0) { // Access RGBA values this way, for example: CurrentPixel.R = (byte)PrimaryColor.R; CurrentPixel.G = (byte)PrimaryColor.G; CurrentPixel.B = (byte)PrimaryColor.B; CurrentPixel.A = (byte)PrimaryColor.A; } } if(Amount2 == 2) { if (y % Amount1 == 0) { // Access RGBA values this way, for example: CurrentPixel.R = (byte)PrimaryColor.R; CurrentPixel.G = (byte)PrimaryColor.G; CurrentPixel.B = (byte)PrimaryColor.B; CurrentPixel.A = (byte)PrimaryColor.A; } } dst[x,y] = CurrentPixel; } } } } Well, that's it - my first plugin. Here is the link to the dll - http://Spongey437.googlepages.com/lines.dll Also, this effect will appear in the Render submenu in PdN. I don't know about you guys but I wish all the effects were subgrouped in some way as there are a ton of them now and they go off the page. Lines.zip

Well, in reply to jsonchiu's request to post something that can be done with it (Great plugin BTW - I had posted a tutorial on how to do this manually earlier) here is a cool looking frame I came up with using just the bevel effect here. Request - any way that you can get it to support odd shapes? Right now it only creates square box bevels. So if you select a round shape, it doesnt work quite right on it. Anyway, here's the pic

Very nice.

Other things you could try to get rid of some of the roughness are the median blur, or try the oil painting effect. I usually use that to smooth things out a bit.

First you have to save it online somewhere, then just use the location for that site and image.

Try this tutorial for doing that. http://paintdotnet.12.forumer.com/viewtopic.php?t=4196

When you save it as a .JPG image, in PDN in gives you the option to select how much you want to change the quality. It usually defaults to 100%, but if you change it to 50% you might still keep a decent image but it will decrease the file size. Also, try a saving it as a few different file types - GIF files are typically the smallest I think. PNG files are typically much larger.

Awesome tutorial - very detailed and easy to follow. Here is mine

You can do it with two pictures but I find that it flows best if the two images come from one picture - the spiderman/venom one was from one picture (as were the other two).

Using the "Let's make a software box" tutorial, I came up with this:
