ID2D1RenderTarget::SetDpi method
Sets the dots per inch (DPI) of the render target.
Syntax
virtual void SetDpi( FLOAT dpiX, FLOAT dpiY ) = 0;
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
This method does not return a value.
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.
