Example 1 with PDFPageHelper

use of annis.libgui.PDFPageHelper in project ANNIS by korpling.

the class EventExtractor method parseSalt.

/**
 * Converts Salt document graph to rows.
 *
 * @param input
 * @param showSpanAnnos
 * @param showTokenAnnos
 * @param mediaLayer  A set of all annotation layers which should be treated as special media layer.
 * @param annotationNames
 * @param replaceValueWithMediaIcon If true the actual value is removed and an icon for playing the media file is shown instead.
 * @param startTokenIndex token index of the first token in the match
 * @param endTokenIndex token index of the last token in the match
 * @param pdfController makes status of all pdfviewer available for the
 * events.
 * @param text If non-null only include annotations for nodes of the specified text.
 * @return
