Constructor Detail

DrawPrintTextLocations

public DrawPrintTextLocations(PDDocument document,
                              java.lang.String filename)
                       throws java.io.IOException

Instantiate a new PDFTextStripper object.

Parameters:

document -

filename -

Throws:

java.io.IOException - If there is an error loading the properties.

Method Detail

main

public static void main(java.lang.String[] args)
                 throws java.io.IOException

This will print the documents data.

Parameters:

args - The command line arguments.

Throws:

java.io.IOException - If there is an error parsing the document.

showGlyph

protected void showGlyph(Matrix textRenderingMatrix,
                         PDFont font,
                         int code,
                         Vector displacement)
                  throws java.io.IOException

Description copied from class: LegacyPDFStreamEngine

Called when a glyph is to be processed. The heuristic calculations here were originally written by Ben Litchfield for PDFStreamEngine.

Overrides:

showGlyph in class LegacyPDFStreamEngine

Parameters:

textRenderingMatrix - the current text rendering matrix, T_rm

font - the current font

code - internal PDF character code for the glyph

displacement - the displacement (i.e. advance) of the glyph in text space

Throws:

java.io.IOException - if the glyph cannot be processed

calculateGlyphBounds

private java.awt.Shape calculateGlyphBounds(Matrix textRenderingMatrix,
                                            PDFont font,
                                            int code)

Throws:

java.io.IOException

stripPage

private void stripPage(int page)
                throws java.io.IOException

Throws:

java.io.IOException

writeString

protected void writeString(java.lang.String string,
                           java.util.List<TextPosition> textPositions)
                    throws java.io.IOException

Override the default functionality of PDFTextStripper.

Overrides:

writeString in class PDFTextStripper

Parameters:

string - The text to write to the stream.

textPositions - The TextPositions belonging to the text.

Throws:

java.io.IOException - If there is an error when writing the text.

usage

private static void usage()

This will print the usage for this document.
