[Anti-alias of B&W drawing]

You could select all the white with magic wand  , press delete and then run antialias assistant or feather once your done create a new layer :AddNewLayer: and move down  :MoveLayerDown: and fill with white using paint bucket   and then flatten the image  :Flatten: Ctrl+Shift+F or (menu item)Image -> Flatten Image

TIP: Hold shift while selecting the white, then you select all white, even if some of the white is "sealed"

[CodeLab v6.12 for Paint.NET 5.0.12 (Updated February 11, 2024)]

PDN crashed when i wrote

private UnaryPixelOps.Desaturate

and then pressed space

Tried this twice, crashed both times

[High Pass v1.2]

This is a simple High Pass filter i created, it took me around 20 minutes for the base, used some extra hours for extra things

Some sample images

The base image:

Surface blur mode:
 


Samples for Indirect UI version with less options:

@ReMake has very kindly rebuilt this plugin to resolve some UI issues.  His version(s) replaces the previously available ZIP.

[Sharpening?]

Thanks, but i found another way to do it   I think i will release it tomorrow, need to get an icon and i have to shut down my computer now   it got a few more settings than photoshop's version but more simple 

[Sharpening?]

 I was fiddling with codelab today at school trying to create a highpass filter like the one in photoshop, i ended up having the same effect like the one in photoshop with a radius of 1 and mine with a radius of 3, mine turned out to be more smooth and i noticed that it only needed to be sharpened a bit to end up like photoshop's, my problem is i dont know how to sharpen it, i already called a gaussian  blur so i can't run another effect like that as i understand, codelab source is below

#region UICode
 int Amount1 = 10; // [0,100] Radius
#endregion


// Setup for using Invert pixel op
private UnaryPixelOps.Invert invertOp = new UnaryPixelOps.Invert();

// Setup for using Normal blend op
private UserBlendOps.NormalBlendOp normalOp = new UserBlendOps.NormalBlendOp();

void Render(Surface dst, Surface src, Rectangle rect)
{
    // Setup for calling the Gaussian Blur effect
    GaussianBlurEffect blurEffect = new GaussianBlurEffect();
    PropertyCollection blurProps = blurEffect.CreatePropertyCollection();
    PropertyBasedEffectConfigToken BlurParameters = new PropertyBasedEffectConfigToken(blurProps);
    BlurParameters.SetPropertyValue(GaussianBlurEffect.PropertyNames.Radius, Amount1);
    blurEffect.SetRenderInfo(BlurParameters, new RenderArgs(dst), new RenderArgs(src));
    // Call the Gaussian Blur function
    blurEffect.Render(new Rectangle[1] {rect},0,1);

    // Now in the main render loop, the dst canvas has a blurred version of the src canvas
    for (int y = rect.Top; y < rect.Bottom; y++)
    {
        for (int x = rect.Left; x < rect.Right; x++)
        {
            ColorBgra CurrentPixel = src[x,y];

            CurrentPixel = invertOp.Apply(CurrentPixel);
            ColorBgra cp = dst[x,y];
            cp.A = Int32Util.ClampToByte(cp.A / 2);
            CurrentPixel = normalOp.Apply(CurrentPixel, cp);
            CurrentPixel = invertOp.Apply(CurrentPixel);
            
            dst[x,y] = CurrentPixel;
        }
    }
}

Tried some different sharpening code i found with google, they didn't work.

Would be nice if i could adjust the sharpness too

[Lightning v1.1]

New version! v1.1 is out!

Added Triangle and Star shapes for gradient options

Gradient control (gradient mode, angle, width, height and show gradient) are now disabled when "Use premade gradient" is checked

Changed default width to 10% and default angle to 90

Link in the first post is updated

[Lightning v1.1]

 Well, would just ask you what you would think of a checkbox "Repeat gradient" So, lets say we take ellipse, set the width to 50 then it will draw the ellipse 2 times by the side of each other, width 25, 4 ellipses, just asking if you would think it makes the UI too complicated  , and on a side note i'm working on a triangle gradient, i can take gradient request but it's not 100% sure ill make them if they're too complicated   

[Lightning v1.1]

Alright, updated the link in the first post, my friend said it worked for him so please try it if you have crashing problems

[Lightning v1.1]

I use 32 bit.

Tried it with multiple wild settings adjustments, no problem so far.

Hmmm, wondering whats causing the problem then, but good to hear it isn't 64 bit only   Was getting afraid of using a lot of time tomorrow in school to figure out how to get it working on 32 bit 

[Lightning v1.1]

I'm using a 32bit OS, it crashed when I was adjusting some values.

Then chances are it's only for 64bit then :S will be looking on it on a virtual machine probably

[Lightning v1.1]

The plugin keeps crashing for me.

Here's the error details

{error}

Strange, a friend of mine also told me about it crashed at him, but no matter what i do i cant recreate it, i also asked my friend how he got it crashing his answer was "I just changed some values with transparent background and 2 layers"

So now i ask you, how did you get it crashing?

edit: Are you using 32bit? I asked my friend he says he use 32bit (OS), dont know if thats the problem, but to others if it works/not works are you then using 32bit or 64bit?

[Lightning v1.1]

 Fixed a problem with the lightning rendering in selections not at point 0,0 - file updated 

[A plug-in request... If anyone has the time and the know how...]

The second one looks like Harmony's sketchy brush. Not sure which came first, though.

I would say the second one looks more like Your link's web brush

[Lightning v1.1]

Hello, this is my first plugin, if you think recognize it then it might be true (clicky clicky).

I have been working on it for some time now, and i think it's ready to be released, i got a lot of help from EER and MadJik

And it does what it say, it creates a lightning BUT without you need to start by drawing a gradient, but it's still possible to use a premade gradient

Some screenshots of what it can do

The most obvious use:
 

Gradients are also possible:
 

And the the not-at-all obvious use:
 

Hope you enjoy using it

If you searched abit you could easily find a smudge tool

[Is there a way to hide controls with IndirectUI?]

Yes

[Is there a way to hide controls with IndirectUI?]

I would like to know if there's a way to hide controls with IndirectUI or do i have to make the UI myself? If i have to design the UI myself could you then give me a sample? I'm using visual studio for this project but i got no idea how to make the UI myself

Thanks in advance

Got a little bug when i tried the new version

[Is it ok to minimize PDN with a plugin?]

No, you shouldn't be doing anything to the Paint.NET UI.

Effect plugins are for rendering content to a layer. FileType plugins are for bringing in content from a stream.

When you try to go outside these boundaries you introduce side effects that may cause Paint.NET to get confused, or users to get confused. Or if your error handling isn't perfect, things can crash or do other stuff. You also make it much more difficult for me going forward to ensure compatibility with your plugin. You may have something that works with whatever the latest version is, but you have no guarantee that later versions of Paint.NET will respond to what you're doing (or that it'll respond correctly, or that it'll respond to the restore command, etc). If you do stuff like this, I'm much more likely to just block your plugin from loading than I am to ensure it still works in the next version.

Ok, thought so, just asked to be sure
