protected override unsafe void OnDraw(IDeviceContext deviceContext)

    deviceContext.DrawImage(Environment.SourceImage);  // preserve background

    // find out where our selection is located
    RectInt32 selection = Environment.Selection.RenderBounds;

    // variables
    int boxSize = Amount2/2;
    int Spacing = Amount3+1;
    int doubleSpacing = Amount3*2;
    int thickness = 2;
    int rndHeight, rndWidth; 
    int step = boxSize*7/10;

    // define your brush and stroke style
    ISolidColorBrush fillBrush = deviceContext.CreateSolidColorBrush(LinearColors.LightGray);
    ISolidColorBrush outlineBrush = deviceContext.CreateSolidColorBrush(LinearColors.Black);
    IStrokeStyle boxStrokeStyle = deviceContext.Factory.CreateStrokeStyle(StrokeStyleProperties.Default);

    // setup drawing mode
    deviceContext.AntialiasMode = AntialiasMode.Aliased;  // or .PerPrimitive

    Random rnd = new Random();
        for (int y = selection.Top; y < selection.Bottom; y += step)
    {
        for (int x = selection.Left; x < selection.Right; x += step)
        {

           //if source pixel is opaque )
           
            rndWidth = rnd.Next(Spacing, doubleSpacing);
            rndHeight = rnd.Next(Spacing, doubleSpacing);

            deviceContext.FillRectangle(x-rndWidth, y-rndHeight, boxSize, boxSize, fillBrush);    
            deviceContext.DrawRectangle(x-rndWidth, y-rndHeight, boxSize, boxSize, outlineBrush, thickness, boxStrokeStyle);    
        }
    }
}

     

    I haven't figured out how to poll the source pixel yet, so I'm just filling selections at the moment. Still, I think looks great! :mrgreen:

    I think the OPDG uses a fixed set of box sizes

    Hadn't considered that. I'll have a look and see if I can make six or seven boxes work.

    Here is a classic script to help you determine when you are on the edge of a selection...

    Nice! Thank you @BoltBait

    Hope that helps... I've found it better to use 'using' statements to ensure graphics objects get disposed of.

    Thanks Red.

    FWIW, the classic effect system is getting deprecated, and soon -- I strongly encourage you to switch to BitmapEffect or GpuEffect (or probably [PropertyBased]GpuDrawingEffect in this case).

    Quite right. I will change of course. The posted code was something from a year or so ago (I just had another play with it to remember where I got to).

    I could use a little help on this one ;)

     

    I'm trying to recreate an outlining effect I saw on Watabou's one-page dungeon generator. I want to surround an object with little gray boxes something like this image.

     

    box-outlining.png

    I had a very rough stab at it. Basically my plan was to step through the image and test the transparency of the target pixel. If it was transparent, throw a little box around it. The code I wrote trying to hack this out was truly awful.

    Since I have no intention of redoing it, I think it would be best to delete this post. Anyway, it's not a big loss for the pdn community.

     

    I disagree. I think this plugin is too good to lose.

     

    If you're willing to release the source code I'm sure someone will recompile and publish it.

    April Update

     

    One new plugin this month:

     

    Warp text along a path xod Writes text along a user-specified path. The plugin uses the SkiaSharp library, so you need to put all three files from the ZIP file into the Effects folder.

     

    *please note* this plugin is currently undergoing revision/rerwrite to make it conform to standards.

     

    There is also the inclusion of an older plugin - which had been missed (thanks @toe_head2001) Alpha Mask (aka Apply Alpha Mask) from @BoltBait's Plugin Pack.

    Can I modify rectangular selection?

    in Paint.NET Discussion and Questions

    Posted

    ^this.

     

    Make the selection & hit the M key twice to enter "modify-the-selection-mode". Click & drag the nubs and/or rotate the selection border the until you have the perfect alignment of the selection rectangle. Press M once more to revert to normal "Move" mode so you can drag/rotate/resize the image region.

     

    Or, if you want to modify the selection border on the fly.....

     

    Hold down the second mouse button (in addition to the first)! The selection border can be dragged around as you are making the selection. In this mode, the keyboard arrow keys move the selection border by one pixel (or 10 pixels if the CTRL key is also held down) for pixel-perfect placement.

    How do I Erase along a drawn line? And Warp Text along a path?

    .I would find the ability to draw an "Eraser LIne" (straight or curved) VERY useful. Draw the line with the line drawing tool, then click on the eraser,

     

    Workaround:

    1. Draw your line on a new blank layer.
    2. Activate the Magic Wand tool 🪄
    3. Click on the transparent area (not the line) to select everything except the line
    4. Invert the selection with Ctrl + I
    5. Activate the layer you want the line removed from
    6. Press the Delete key
    7. Hide or delete the layer you drew the line on.

    2. Is Paint.net capable of this type of Text Formation?

     

    Yes, try this brand new plugin by @xod:

    Good morning.

Is it possible to reduce the size of a photo, while retaining the number of pixels and the entire photo? In other words, is it possible to reduce the size of a photo while retaining all its quality?

I would be happy to have an answer on this.

Thank you and good luck to you.

     

    Reducing the image size reduces the number of pixels.

    • If you want to print the photo at a smaller size, try increasing the DPI (Dots Per Inch) setting in the printing dialog.
    • If you want the file size to be smaller, choose Save As and specify the JPG extension, then lower the quality setting. Specify a different file name so you don't overwrite the original image.

    Sorry didn't make it clear. I uninstalled paint.net properly via Control Panel. I later found some residual files, which I removed.

     

    There may still be files lurking around. Do try the link that @Tactilis suggested:
