@Ash Hmm... dark line? It doesn't work with semi-transparent objects IMO. In order for it to work as intended, you need all the pixels on the edge to be opaque. Also, it will place a very tiny line (barely visible) around it if it has a very light color. ------- The feather plugin in the "grow" mode still use Gaussian Blur, and therefore produce blurred results on the edges, instead of clearcut anti-alias. You can see the difference in these pictures (left: feather 1px, grow, right: anti-alias, amount: 5)

@david.atwell Yes, progressive transparency. Here's how the code works: 1. take a pixel, and determine whether it's a solid or transparent one. 2. if it's a transparent one, change the color to the nearest solid pixel, and the alpha value to the average of the surrounding pixels (with a little bit of tweaking to make it not so blurred). @Ash I intended it to be the Photoshop-quality feather, but then I couldn't make it to feather at different amount of pixels.

Smooth out the edges.

Ok, so as you know, Boltbait's feather plugin uses Gaussian Blur to soften the edges. I have always found it doesn't quite work the way I wanted. So, I wrote another plugin for smoothing edges, but still keep it clear, not blurred. With this plugin, the result will be clear and smooth, just like any other anti-aliased shapes. Amount: pretty self explanatory. Slide it around to see different effects. Strength: opaqueness of the "feathering" Default 980 for anti-aliasing. Turn it down for feathering. Soft outline/None: Default is on. If turned on, it would darken the edge a little bit to make it clearer. If the image has light colors, turn it off, or else there would be an ugly dark outline. Example: let's feather a cat... (cut from Bob's siggie). Before: the edge is too hard, and jagged After: the edge is smoothed out (anti-aliased)! This plugin can also blur the edges with a medium-high amount and low strength Download Source: Enjoy! Update1: added "strength" slide bar and expand "Amount" to 30 Update2: FULLY fixed transparency bug! Update3: added "soft outline" slider to adjust edge enhancement Update4: fixed "no anti-alias on low alpha" bug. The plugin should now antialias equally for any alpha value. Also, added a menu icon!

Png can be optimized. I use Irfanview to save it with highest compression.

Couldn't you just set myForm.Opacity?

Fixed a few minor bugs.

Lolz almost forgot about it... *done*

Dunno... but Windows has serious memory leak... beware of that. Usually restarting the computer will solve problems like that.

I think Irfan View should do the job. It's a good image viewer too.

You can just reverse the primary color and the secondary color. Btw, thanks for the great responses!

Update: fixed transparency bug. Also, improved the render a little bit (it should be smoother now), and added a menu icon.

Fixed selection bug. It should now be able to apply effect to selected areas. I'm trying to solve the transparency bug... It should be done pretty soon.

Fine. I thought everybody knows what it is... it's very common in image manipulation programs. EDIT: screenshots added

Meh the bevel effect available in most image editing programs (except pdn) This effect will be under the menu Effects->Renders Primary color = highlight Secondary color = shadow Example: Ash's tiger: -> A few buttons on Ash's siggie: This link appears to be broken (09 Feb 2013 - EER) >> dll: http://jason.jjtchiu.com/downloads/Bevel_v1.4.0.0.dll Download the DLL from the attachment at the bottom of this post. source: int Amount1=7; //[0,200]Depth int Amount2=20; //[0,100]Strength 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); int left = (int)selection.Left; int top = (int)selection.Top; int right = (int)selection.Right; int bottom = (int)selection.Bottom; 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]; //top if ((x-left) >= (y-top) && (y-top) <= Amount1 && x+(y-top) < right) { CurrentPixel = transformPixel(y-top, CurrentPixel, PrimaryColor); } //left else if ((y-top) >= (x-left) && (x-left) <= Amount1 && (x-left)+y < bottom) { CurrentPixel = transformPixel(x-left, CurrentPixel, PrimaryColor); } //bottom else if ((x-left) >= (bottom-y) && (bottom-y) <= Amount1 && x+(bottom-y) <= right) { CurrentPixel = transformPixel(bottom-y, CurrentPixel, SecondaryColor); } //right else if ((y-top) >= (right-x) && (right-x) <= Amount1 && (right-x)+y < bottom) { CurrentPixel = transformPixel(right-x, CurrentPixel, SecondaryColor); } dst[x,y] = CurrentPixel; } } } } ColorBgra transformPixel(float px_from_edge, ColorBgra CurrentPixel, ColorBgra NewColor) { //set amount of background interference 0~1 (ie how much it blends to the background) float diff = (float)(0.05 + px_from_edge/Amount1); float strength = (float)((float)(100 - Amount2) / 100 + (float)0.35); diff = diff * strength; if (diff > 1) { diff = 1; } else if (diff < 0) { diff = 0; } //some vars just for convenience, more readable float div = diff + 1; float invrt_diff = 1 - diff; //we set the RGB to primary color if it is completely transparent (black is the default) //That should solve if (CurrentPixel.A == 0) { CurrentPixel.R = NewColor.R; CurrentPixel.G = NewColor.G; CurrentPixel.B = NewColor.B; } //and we are ready to color the pixels //ex: if 70% background interference //we have 70% of original color's R plus 30% of the new color's R CurrentPixel.R = (byte)((invrt_diff * (float)NewColor.R) + (diff * (float)CurrentPixel.R)); CurrentPixel.G = (byte)((invrt_diff * (float)NewColor.G) + (diff * (float)CurrentPixel.G)); CurrentPixel.B = (byte)((invrt_diff * (float)NewColor. + (diff * (float)CurrentPixel.); //transparency values need special manipulation to prevent bad-looking renders float temp = CurrentPixel.A + NewColor.A; if (temp > 255) { temp = 255; } temp = ((int)CurrentPixel.A + temp) / 2; if (CurrentPixel.A < 255) { temp = temp * (1 + (float)invrt_diff); } if (temp > 255) { temp = 255; } CurrentPixel.A = (byte)temp; //and we are done return CurrentPixel; } Enjoy! Update1: fixed selection bug. The plugin should now be able to apply filter to selected areas. Update2: fixed transparency bug. It should now render correctly. Update3: moved to Effects->Renders Update4: fully fixed transparency "color" Bevel_v1.4.0.0.zip

In the layer with the circle, change the transparency to 128.

Anyways, when did this become 2 pages? :shock: My eyes are bad these days...

Can somebody compile a package that works in Visual Studio .Net 2003? I haven't got around to upgrade my 4-year-old program yet. Right now I can only use codelab...

Done Nope, I wrote the code from scratch. ------------------------------------------------------------------------------- Update: fixed transparency bug. You can now apply the plugin using a semi-transparent brush color and it will multiply the color to the background just like what it does when you use the line/curve tool.

Added "Antialias Level" option and a simple menu icon

Uh... you can't add a byte to a int.

Added brush width slide bar.

Wow, thanks so much for the tut!

Yeah, but this plugin take options like brush width and exact amount of pixels between lines. :wink:

I've been searching for a plugin that makes diagonal lines for a long time... Since I couldn't, I decided that maybe I should make one myself! It turned out to be a lot easier than I thought, and here it is! The plugin will be placed under Effects -> Render Download Source: Enjoy! Update1: added brushwidth slide bar. Update2: added antialias level & menu icon. Update3: fixed transparency bug. Update4: added angle slide bar. Update5: added colorwheel, alpha slide bar, fixed more transparency issues
