Construct a word list for a rectangular region.
void pdfBuildWordListFromRect2(PDFHandle pdf, int page, double x0, double y0, double x1, double y1)
This function constructs a word list for a rectangular region of a page.

The rectangle is defined by two opposite corners: (x0, y0) and (x1, y1). The coordinates are in PDF coordinate space.

After building a word list, call pdfGetNumWords and pdfGetWord to access the words.

XpdfText holds a word list for one page or region at a time. If you call pdfBuildWordList or pdfBuildWordListFromRect2 again, the new word list will replace the previous one.

Word ordering within the word list is affected by the text extraction mode - see the "Setting parameters" section in the function list.

/* make word list for (200,300)-(500,400) on page 1 */ pdfBuildWordListFromRect2(pdf, 1, 200, 300, 500, 400);
