High DPI
Enabling PerMonitorV2 is recommended.
Application.SetHighDpiMode(HighDpiMode.PerMonitorV2);Windows then hands the control a physical-pixel client area instead of scaling a bitmap, and the control scales its own drawing for a crisp result.
Rendering to an arbitrary Graphics
| Member | What it does |
|---|---|
RenderTo(graphics, width, height, scale) | Renders at a logical size you give |
RenderFrame(graphics, physicalWidth, physicalHeight) | Physical pixels (zoom included) |
Useful for generating thumbnails or writing images headlessly.
Printing
using var doc = control.CreatePrintDocument();
doc.Print();It returns a PrintDocument, so you can hand it straight to the standard print dialog or a
print preview. See Printing and Page Setup.
