UT_sint32 &  iStart,

) [inline, protected]

Calculates the extents of string corresponding to glyphstring from *character* offset iStart to iEnd (excluding iEnd);

iDir is the visual direction of the text

pUtf8 pointer to the corresponding utf8 string; can be NULL if pLogOffsets is provided

pLogOffsets is array of logical offsets (see gr_UnixPangoRenderInfo::m_pLogOffsets); if NULL, it will be calculated using the corresponding utf8 string and pointer returned back; the caller needs to delete[] it when no longer needed.

On return iStart and iEnd contain the offset values that correspond to the returned extent (e.g., if the original iStart and/or iEnd are not legal character postions due to clustering rules, these can be different from the requested values).

void GR_CairoGraphics::justify ( GR_RenderInfo &  ri  )  [virtual]

We take the same approach as with Uniscribe; we store the justification amount in a separate array of the ri and add it to the offsets before we draw. We will probably need some static buffers to speed things up

It requires as input RI.m_iJustificationAmount and RI.m_iJustificationPoints. These are determined in fp_TextRun using calculations in layout units

void GR_CairoGraphics::measureRenderedCharWidths ( GR_RenderInfo &  ri  )  [virtual]

This function is called after shaping and before any operations are done on the glyphs. Although Pango does not have a separate character placement stage, we need to scale the glyph metrics to appropriate zoom level (since we shape % zoom).

NB: this is probably not ideal with int arithmetic as moving from one zoom to another, and back we are bound to end up with incorrect metrics due to rounding errors.
