ID2D1RenderTarget::SetDpi method (d2d1.h)

  • Article

Sets the dots per inch (DPI) of the render target.

Syntax

void SetDpi(
  FLOAT dpiX,
  FLOAT dpiY
);

Parameters

dpiX

Type: FLOAT

A value greater than or equal to zero that specifies the horizontal DPI of the render target.

dpiY

Type: FLOAT

A value greater than or equal to zero that specifies the vertical DPI of the render target.

Return value

None

Remarks

This method specifies the mapping from pixel space to device-independent space for the render target. If both dpiX and dpiY are 0, the factory-read system DPI is chosen. If one parameter is zero and the other unspecified, the DPI is not changed.

For ID2D1HwndRenderTarget, the DPI defaults to the most recently factory-read system DPI. The default value for all other render targets is 96 DPI.
