Member Function Documentation

void GRE::GROUPVIEW::CheckRendered (   )

Check if existing renderings are still valid.

ERRVALUE GRE::GROUPVIEW::ComputeTrans (   )

Compute all transformations.

ERRVALUE GRE::GROUPVIEW::DrawActiveOverlay (   )

Draw all 'active' elements to overlay buffer.

const GRE_VIEWPOINT3D* GRE::GROUPVIEW::Get3dViewPoint (   )  const [inline]

Get 3D viewpoint. Definition at line 80 of file groupview.h.

const LRECT2D& GRE::GROUPVIEW::GetDeviceRectUsed (   )  const [inline]

Get device rectangle used for rendering. This is a nominal rectangle based on layer extents and may not account for symbology and marginalia. Returned rectangle may not be suitable for clipping during drawing, but will be suitable for selection of source object elements. Definition at line 87 of file groupview.h.

GRE_GROUP* GRE::GROUPVIEW::GetGroup (   )  const [inline]

Get associated GRE_GROUP. Definition at line 91 of file groupview.h.

RENDERBUFFER& GRE::GROUPVIEW::GetRenderBuffer (  RENDERTYPE  RenderType  )  [inline]

Get rendering buffer for specified rendering type (non-const). Parameters: RenderType  Rendering type Definition at line 100 of file groupview.h.

const RENDERBUFFER& GRE::GROUPVIEW::GetRenderBuffer (  RENDERTYPE  RenderType  )  const [inline]

Get rendering buffer for specified rendering type (const). Parameters: RenderType  Rendering type Definition at line 95 of file groupview.h.

double GRE::GROUPVIEW::GetRotationAngle (   )  const [inline]

Get rotation angle. Definition at line 105 of file groupview.h.

double GRE::GROUPVIEW::GetRotationCos (   )  const [inline]

Get rotation cosine. Definition at line 109 of file groupview.h.

double GRE::GROUPVIEW::GetRotationSin (   )  const [inline]

Get rotation sine. Definition at line 113 of file groupview.h.

GRE_VIEW* GRE::GROUPVIEW::GetView (   )  const [inline]

Get associated GRE_VIEW. Definition at line 117 of file groupview.h.

bool GRE::GROUPVIEW::Is3D (   )  const [inline]

Determine if drawing in 3D. Definition at line 121 of file groupview.h.

bool GRE::GROUPVIEW::Is3dStereo (   )  const

Determine if drawing 3D in stereo.

bool GRE::GROUPVIEW::IsGroupOverlappedDevice (   )  const [inline]

Determine if group overlaps view device display area. Definition at line 129 of file groupview.h.

void GRE::GROUPVIEW::ResetRendered (  GRE::RENDERTARGET  target = GRE::RENDERTARGET_GroupAll  )

Reset rendered status so redraws.
