◆ getDevicePixelRatio() [1/2]

virtual double SoViewerProxy::getDevicePixelRatio ( )

inlinevirtual

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

Reimplemented in SoResolutionIndependentViewerProxy.

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 >

ML_OPENGL_END_NAMESPACE T GLHiDPIScale ( T x )

Convenience template function to scale a value.

Definition at line 68 of file mlGLHiDPI.h.

References mlrange_cast(), and T.

◆ glLineStippleScaled()

MLOPENGL_EXPORT void glLineStippleScaled	(	GLint	factor,
		GLushort	pattern )

Sets the line stipple pattern.

The resulting pattern multiplier is guaranteed to be at least 1.

◆ glLineWidthScaled()

ML_OPENGL_START_NAMESPACE MLOPENGL_EXPORT void glLineWidthScaled ( GLfloat width )

Sets the width of rasterized lines.

The resulting line with is guaranteed to be at least 1.0.

◆ glPointSizeScaled()

MLOPENGL_EXPORT void glPointSizeScaled ( GLfloat size )

Sets the diameter of rasterized points.

The resulting point size is guaranteed to be at least 1.0.
