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 3264 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 3343 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.
