pdfGetWordCharBox
Get the bounding box of a character in a word.
void pdfGetWordCharBox(PDFWordHandle word, int charIdx,
double *xMin, double *yMin, double *xMax, double *yMax)
This function returns the bounding box of
the
charIdxth character in a word (whose
handle was obtained with pdfGetWord).
The xMin, yMin, xMax,
and yMax coordinates are in a coordinate space that
places (0,0) at the top-left corner of the page and has 72 units per
inch (same coordinate system as used by pdfExtractTextFromRect).
This function works on Unicode characters (used internally in
XpdfText). The pdfGetWordLength function returns the number of
Unicode characters.
This function is identical to pdfGetWordCharBox2 except that it
returns points in a top-down coordinate space.
