Extract text from a rectangular region.
extractTextFromRect([in] int page, [in] double x0, [in] double y0, [in] double x1, [in] double y1, [out, retval] BSTR *text)
This function extracts text from a rectangular region on a page, and returns the resulting text in a string.

The rectangle is defined by two opposite corners: (x0, y0) and (x1, y1). The coordinates are in a coordinate space that places (0,0) at the top-left corner of the page and has 72 units per inch.

extractTextFromRect throws an error if text extraction is prohibited by this PDF file.

See the "Setting parameters" section in the function list for settings that affect text extraction.

This function is identical to extractTextFromRect2 except that it takes points in a top-down coordinate space.
