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 83 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 90 of file groupview.h.

GRE::GROUP* GRE::GROUPVIEW::GetGroup

(

)

const [inline]

Get associated GRE::GROUP.

Definition at line 94 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 103 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 98 of file groupview.h.

double GRE::GROUPVIEW::GetRotationAngle

(

)

const [inline]

Get rotation angle.

Definition at line 108 of file groupview.h.

double GRE::GROUPVIEW::GetRotationCos

(

)

const [inline]

Get rotation cosine.

Definition at line 112 of file groupview.h.

double GRE::GROUPVIEW::GetRotationSin

(

)

const [inline]

Get rotation sine.

Definition at line 116 of file groupview.h.

GRE::VIEW* GRE::GROUPVIEW::GetView

(

)

const [inline]

Get associated GRE::VIEW.

Definition at line 120 of file groupview.h.

bool GRE::GROUPVIEW::Is3D

(

)

const [inline]

Determine if drawing in 3D.

Definition at line 124 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 132 of file groupview.h.

void GRE::GROUPVIEW::ResetRendered

(

GRE::RENDERTARGET

target = GRE::RENDERTARGET_GroupAll

)

Reset rendered status so redraws.
