Description
Extracts text from parser.The function extracts the text of a page with the same algorithm that DynaPDF.FindText uses to find text on a page. In order to get exactly the same result the flag "SortTextX" must be set.
The function DynaPDF.ExtractText of the PDF instance calls in fact this function internally.
The optional parameter Area defined using left, bottom, right and top can be set to restrict text extraction to that rectangle. The rectangle must be defined as if the page would be viewed in a PDF viewer. That means in bottom up coordinates and the orientation must be considered. The page coordinate system is de-rotated before text extraction starts since this produces better results. The width and height must be calculated from the crop box if set, or from the media box otherwise. Note also that the width and height must be exchanged if the orientation is 90, -90, 270, or -270 degrees.
