Method Detail

initialize

public void initialize(String pdfDocumentPath,
              int bufferSize,
              boolean allowAsyncInitialization)

Initializes TextExtractor instance.

Parameters:

pdfDocumentPath - Path to a pdf document.

bufferSize - Maximum size of content in bytes that can be kept in memory.

allowAsyncInitialization - Allows async initialization of resources.

initializeAlternative

public void initializeAlternative(String pdfDocumentPath)

Initializes TextExtractor instance.

Parameters:

pdfDocumentPath - Path to a pdf document.

buildProperties

public long buildProperties(com.aspose.pdf.groupprocessor.ByteRange range,
                   com.aspose.pdf.groupprocessor.PdfTreeNode parentNode)

Builds tree of nodes those contain all pdf parameters with their values.

Parameters:

range - Byte range where to parse parameters.

parentNode - Initial (root) node for building tree.

extractJustValue - For recursive calling. Just shows that next recursive function should find parameter value but not parameter itself.

Returns:

Last index of the parsed range.
