◆ getDevicePixelRatio() [1/2]

virtual double SoViewerProxy::getDevicePixelRatio ( )

inlinevirtual

Returns the ratio between physical pixels and device-independent pixels for the viewer.

Reimplemented in SoResolutionIndependentViewerProxy, and SoQtViewerProxy.

Definition at line 221 of file SoViewerProxy.h.

◆ getDevicePixelRatio() [2/2]

static double SoViewerElement::getDevicePixelRatio ( SoState * state )

static

Convenience method which calls the corresponding method of SoViewerProxy.

◆ GLHiDPIScale()

template<class T >

T GLHiDPIScale ( T x )

Convenience template function to scale a value.
