virtual void GR_Win32Font::_clearAnyCachedInfo (  )  [inline, protected, virtual]

Reimplemented in GR_Win32USPFont.

GR_Win32CharWidths* GR_Win32Font::_getCharWidths (  )  const [inline, protected]
void GR_Win32Font::_updateFontYMetrics ( HDC  hdc,
HDC  printHDC 
) [protected]

hdc -- handle to the primary DC on which we draw printHDC -- handle to the DC on which we want to measure the font (typically the printer) can be NULL (in which case hdc will be used

NB: the caller must ensure that the corresponding HFONT is already selected onto the DC represented by printHDC (or hdc if NULL).

bool GR_Win32Font::glyphBox ( UT_UCS4Char  g,

) [virtual]

UT_Rect of glyph in Logical units. rec.left = bearing Left (distance from origin to start) rec.width = width of the glyph = distance from the origin to the top of the glyph rec.height = total height of the glyph

This function will only work on win NT -- check the return value before doing anything with the rectangle (win9x implementation would have to use GetGlyphOutlineA() and convert the UT_UCS4Char to an appropriate ansi value

Implements GR_Font.
