Examples of org.apache.poi.hwpf.model.PicturesTable

org.apache.poi.hwpf.model.PicturesTable
Holds information about all pictures embedded in Word Document either via "Insert -> Picture -> From File" or via clipboard. Responsible for images extraction and determining whether some document�s piece contains embedded image. Analyzes raw data bytestream �Data� (where Word stores all embedded objects) provided by HWPFDocument. Word stores images as is within so called "Data stream" - the stream within a Word docfile containing various data that hang off of characters in the main stream. For example, binary data describing in-line pictures and/or formfields an also embedded objects-native data. Word picture structures are concatenated one after the other in the data stream if the document contains pictures. Data stream is easily reachable via HWPFDocument._dataStream property. A picture is represented in the document text stream as a special character, an Unicode \u0001 whose CharacterRun.isSpecial() returns true. The file location of the picture in the Word binary file is accessed via CharacterRun.getPicOffset(). The CharacterRun.getPicOffset() is a byte offset into the data stream. Beginning at the position recorded in picOffset, a header data structure, will be stored. @author Dmitry Romanov
