Exact Plain Text Strategy Extracts Simple Plain Text By Glyphs
The exact plain text strategy is simliar to the plain text strategy but it uses the detail level of the glyph strategy to extract the text. That said it will recreate the resulting text by sorting, comparing and concatenating individual glyphs and will ignore existing text items from the PDF document.
Especially in concunction with e.g. a rectangle filter this strategy will return much more precise result.
The strategy is represented by the
The result will be also a standard PHP string.
The exact plain text strategy makes use of the glyph strategy which extracts each single glyph including its metrics in the order in which it appears in the PDF data stream.
If a space between words is "faked" by a character spacing value this strategy is able to recognize this as a word separator!
An instance has to be created individually and passed to the main class:
$strategy = new \SetaPDF_Extractor_Strategy_ExactPlain(); $extractor = new \SetaPDF_Extractor($document); $extractor->setStrategy($strategy);
You can get a string result by this strategy by calling the
getResultByPageNumber() method for each individual page:
