Paintnet plugin pack outline3/20/2024 ![]() Here is a plugin that Illnab1024 wrote to paste from the clipboard into your current selection. Rick explained to me that you can only access the clipboard from an STA thread. The one on the right is more smooth than the one on the left.Īccessing the clipboard from a Paint.NET plugin is somewhat tricky. Once you run this, zoom in and look at the two lines that were drawn. Then, we need to set the SmoothingMode of the canvas, like this: Just like when drawing text, when drawing lines and shapes to the canvas, we need to be sure to copy the source canvas to the destination canvas before drawing our stuff. G.DrawString(Amount1, SelectedFont, Brush1, column, row) SelectedFont = new Font("Arial", Amount3) If font creation fails, use Arial font SelectedFont = new Font(Amount2.Name, Amount3) G.TextRenderingHint = .SingleBitPerPixelGridFit SolidBrush Brush1 = new SolidBrush(Amount5.ToColor()) Create a brush and graphics surface to write on Int row = (int)Math.Round(((Amount6.Second + 1) / 2) * (selection.Bottom - selection.Top)) Int column = (int)Math.Round(((Amount6.First + 1) / 2) * (selection.Right - selection.Left)) Determine where the text will be written Pair Amount6 = Pair.Create( 0.0, 0.0 ) // Location String Amount1 = "Test" // TextįontFamily Amount2 = new FontFamily("Arial") // Fontīyte Amount4 = 1 // Smoothing|None|Anti-Alias|ClearTypeĬolorBgra Amount5 = ColorBgra.FromBgr(0,0,0) // Color Choose your method and select the corresponding line below to add to your script: There are several methods you can choose from in order to anti-alias text. In order to anti-alias, just specify the graphics TextRenderingHint. Typically, if you don't specify that your text should be rendered with an anti-alias effect it will come out very blocky. Starting with this simple script, let's take a look at what it would entail to add more options and anti-alias the text. Of course, this is a very simple example and there is much room for improvement. G.DrawString("Paint.NET Rocks!", SelectedFont, Brush1, selection.Left, selection.Top) Graphics g = new RenderArgs(dst).Graphics įont SelectedFont = new Font("Arial", 16) SolidBrush Brush1 = new SolidBrush(Color.Red) And, since we won't be looping over every single pixel in the destination canvas, you might as well get rid of those inner loops too! ![]() We also won't need any of the variables (except the first one, selection), so get rid of them. Well, for this simple example, we won't need any UI controls, so delete those. Access RGBA values this way, for example: Int BrushWidth = (int)EnvironmentParameters.BrushWidth įor (int y = rect.Top y < rect.Bottom y++)įor (int x = rect.Left x < rect.Right x++) Int CenterY = ((selection.Bottom - selection.Top) / 2)+selection.Top ĬolorBgra Primar圜olor = (ColorBgra)EnvironmentParameters.Primar圜olor ĬolorBgra Secondar圜olor = (ColorBgra)EnvironmentParameters.Secondar圜olor Int CenterX = ((selection.Right - selection.Left) / 2)+selection.Left Rectangle selection = EnvironmentParameters.GetSelection(src.Bounds).GetBoundsInt() Delete any of these lines you don't need Void Render(Surface dst, Surface src, Rectangle rect) The easiest way to do that is to copy all pixels from Src to Dst, then render the text to the Dst canvas. In order for this to work properly, we must ensure that every pixel is written to the destination canvas. Rendering text to the image is interesting because when you are rendering text, not every pixel is written. I hope you find something here that is useful to you. I have collected these ideas here in one place so that you and I could find them easily when getting ready to write a plugin. ![]() Most of the scripts here I wrote myself and some I did not. I have also included here some other tips and tricks that I have learned along the way. but, what if you don't want to write to every pixel? Like, say, rendering text on the canvas or drawing lines/shapes? Well, we can also do this type of thing with CodeLab. ![]() For example, you understand that a plugin must write to every pixel in the destination canvas. But, you may have some ideas for plugins that just don't fit the normal mold. If you've been following along so far, you have learned a great deal about how plugins work and are put together. Now that you've mastered those effects, it is time to move on to something a little more off the wall. If you haven't already done so, please go back and review the following:īack? OK, good.
