Detailed Description

Base class for all your drawing needs.

Constructor & Destructor Documentation

virtual MGD::CONTEXT::~CONTEXT ( ) [virtual]

MGD::CONTEXT::CONTEXT ( MGD::DEVICE * disp ) [protected]

Default Constructor.

Member Function Documentation

ERRVALUE MGD::CONTEXT::_DrawGlyph ( MGD::FONT * font,

double x,

double y,

double baseangle,

const MGD::STRINGDATA & gidstr,

int num

) [inline, protected]

Draw the nth glyph in gidstr at the given location.
The default implementation just calls the font->DrawGlyph() method. Special devices could elect to output the glyph itself. The gidstr.m_str is the string being drawn (in Unicode)
Definition at line 3248 of file mgd2.h.

double MGD::CONTEXT::_NextGlyphPosition ( MGD::FONT * font,

double * x,

double * y,

double baseangle,

const MGD::STRINGDATA & gidstr,

int num,

double SpaceExtra = 0.0,

double GlyphExtra = 0.0

) [inline, protected]

Update the x and y parameters as if the nth glyph in gidstr had just been rendered.
The default implementation just calls the font->NextPosition() method, which uses the m_pos[] settins in the gidstr. Returns the change in x (used to calculate string with by passing base angle of 0) SpaceExtra and GlyphExtra are added between each space and each glyph (including spaces) to acheive "full" justification. This function could be made virtual, but that would be a bad idea.
Definition at line 3327 of file mgd2.h.

ERRVALUE MGD::CONTEXT::AddExteriorToClip ( const LRECT2D & rect )

Add to the clip mask drawing exclusion area using a rectangle.
Areas OUTSIDE the rectangle will be clipped (i.e., they won't draw) The default method twiddles bits in a clip device which is used as a bitmask through which all FillSpans operate. ( Currently only used in autolabl.c, and only) Should be replaced by IntersectClipRegion()

ERRVALUE MGD::CONTEXT::AddToClip ( const REGION2D & region )

Add to the clip mask drawing exclusion area using a REGION2D.
Areas added will NOT draw (i.e. they WILL be clipped). The default method clears bits in a clip device which is used as a bitmask through which all FillSpans operate.

ERRVALUE MGD::CONTEXT::AddToClip ( const POLYLINE & polyline )

Add to the clip mask drawing exclusion area using a POLYLINE.
Areas added will NOT draw (i.e. they WILL be clipped). The default method clears bits in a clip device which is used as a bitmask through which all FillSpans operate.

ERRVALUE MGD::CONTEXT::AddToClip ( const LRECT2D & rect )

Add to the clip mask drawing exclusion area using an LRECT2D.
Areas added will NOT draw (i.e. they WILL be clipped). The default method clears bits in a clip device which is used as a bitmask through which all FillSpans operate.

ERRVALUE MGD::CONTEXT::AddToClip ( const DRECT2D & rect )

Add to the clip mask drawing exclusion area using a DRECT2D.
Areas added will NOT draw (i.e. they WILL be clipped). The default method clears bits in a clip device which is used as a bitmask through which all FillSpans operate.

int MGD::CONTEXT::AllocPrivDataIndex ( ) [static]

Allocate a private data index.
This is uses as an argument to GetPrivData and SetPrivData

bool MGD::CONTEXT::Calculate3dDepthFunction ( const DPOINT3D & p1,

const DPOINT3D & p2,

const DPOINT3D & p3,

const double viewPlaneDistance,

const bool isPerspective,

const MAT3X3 & matrix

)

Calculate 3d depth function for given three points.

Parameters:

p1 Points defining a plane

viewPlaneDistance View plane distance

isPerspective Perspective or orthogonal projection

matrix Transformation from destination rectangle to canonical view plane

bool MGD::CONTEXT::CheckZ ( const bool isPerspective,

const float checkvalue,

const float value

) [inline, static, protected]

Definition at line 3211 of file mgd2.h.

void MGD::CONTEXT::ClearClipMask ( )
