Member Function Documentation

virtual void makVrv::DtGridLinesDrawer::setChannel ( DtOsgChannel *  channel )

virtual

Set the channel to draw the grid lines on.

virtual void makVrv::DtGridLinesDrawer::setChannelDimensions ( int  startChannelX, int  startChannelY, int  endChannelX, int  endChannelY  )

virtual

Set the channel dimensions.

Reimplemented in makVrv::DtGeocentricGridLinesDrawer.

virtual void makVrv::DtGridLinesDrawer::setupOverlay ( )

virtual

Get the overlay to use for our channel.

virtual void makVrv::DtGridLinesDrawer::setupFont ( )

virtual

Get the font to use fron the font manager.

virtual double makVrv::DtGridLinesDrawer::lookupClosestLatLonSpacing ( double  minimumSpacingRadians )

virtual

Find the best allowable lat,lon spacing given the minimum requirement.

virtual double makVrv::DtGridLinesDrawer::lookupClosestCartesianSpacing ( double  minimumSpacing )

virtual

Find the best allowable cartesian spacing given the minimum requirement.

virtual double makVrv::DtGridLinesDrawer::lookupClosestGarsSpacing ( double  minimumSpacing ) const

virtual

Find the best allowable GARS spacing given the minimum requirement. Note that this can return -1.0 which is a 'don't draw' indicator.
