Clipboard access from plugins


Recommended Posts

I'm updating a plugin that uses the clipboard, and I believe I read fairly recently that there were new PDN routines for accessing it. However I did several forum searches, and couldn't find anything. Could someone either give me a link, or better yet, provide a description of the new methods.

Just let CodeLab write the code for you.


CodeLab: File > New, choose the Clipboard Effect choose your canvas. Generate code to see what you get.

Surface wrk = null;

private Surface clipboardSurface = null;
private bool readClipboard = false;

protected override void OnDispose(bool disposing)
    if (disposing)
        // Release any surfaces or effects you've created
        wrk?.Dispose(); wrk = null;
        clipboardSurface?.Dispose(); clipboardSurface = null;


// This single-threaded function is called after the UI changes and before the Render function is called
// The purpose is to prepare anything you'll need in the Render function
void PreRender(Surface dst, Surface src)
    if (wrk == null)
        wrk = new Surface(src.Size);

    if (!readClipboard)
        readClipboard = true;
        clipboardSurface = Services.GetService<IClipboardService>().TryGetSurface();
    // Copy from the Clipboard to the wrk surface
    for (int y = 0; y < wrk.Size.Height; y++)
        if (IsCancelRequested) return;
        for (int x = 0; x < wrk.Size.Width; x++)
            if (clipboardSurface != null)
                //wrk[x,y] = clipboardSurface.GetBilinearSample(x, y);
                //wrk[x,y] = clipboardSurface.GetBilinearSampleClamped(x, y);
                wrk[x,y] = clipboardSurface.GetBilinearSampleWrapped(x, y);
                wrk[x,y] = Color.Transparent;

// Here is the main multi-threaded render function
// The dst canvas is broken up into rectangles and
// your job is to write to each pixel of that rectangle
void Render(Surface dst, Surface src, Rectangle rect)

    // Step through each row of the current rectangle
    for (int y = rect.Top; y < rect.Bottom; y++)
        if (IsCancelRequested) return;
        // Step through each pixel on the current row of the rectangle
        for (int x = rect.Left; x < rect.Right; x++)
            ColorBgra SrcPixel = src[x,y];
            ColorBgra WrkPixel = wrk[x,y];
            ColorBgra DstPixel = dst[x,y];

            ColorBgra CurrentPixel = WrkPixel;

            // TODO: Add additional pixel processing code here

            dst[x,y] = CurrentPixel;
