PDFBox get begintext sezione (BT) ET coordinate

Question

Per favore qualcuno può aiutare a ottenere le coordinate reali di pixel per PDF begintext sezioni? Sto usando PDFBox per recuperare i testi da file PDF, ma ora ho bisogno di ottenere Rects sorounding che le sezioni di testo / paragrafi.

$contents = $page->getContents();
$contentsStream = $page->getContents()->getStream();
$resources=$page->getResources();
$fonts = $resources->getFonts();
$xobjects = $resources->getImages();
$tokens=$contentsStream->getStreamTokens();

mi piacerebbe ottenere l'output qualcosa di simile funzione PrintTextLocations fa per ogni parola / carattere. Posso ottenere in basso a sinistra e coordinare, ma come ottenere la larghezza e la parte superiore coordinata?

PrintTextLocations:

Answer 1

... come sezione BT fornisce le coordinate in basso a sinistra, è necessario analizzare attraverso tutte le parole / le lettere contenute in blocco BT corrente per ottenere tutte le altre coordinate. Prima altezza parola + BT bottom = top, max (a sinistra coordinare + larghezza) = destra, ultima parola in basso = coordinata in basso.

Spero che questo aiuta qualcuno ...

stringa Esempio per una singola lettera:

string[32.94,35.099976 fs=8.0 xscale=1.0 height=4.4240003 space=2.2240002 width=3.959999]p

Estratte, analizzato e la linea preparato:

32.94,35.099976 fs=8.0 xscale=1.0 height=4.4240003 space=2.2240002 width=3.959999
