Constructor Detail

PrintTextLocations

public PrintTextLocations()
                   throws IOException

Instantiate a new PDFTextStripper object.

Throws:

IOException - If there is an error loading the properties.

Method Detail

main

public static void main(String[] args)
                 throws IOException

This will print the documents data.

Parameters:

args - The command line arguments.

Throws:

IOException - If there is an error parsing the document.

writeString

protected void writeString(String string,
                           List<TextPosition> textPositions)
                    throws 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:

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

showGlyph

protected void showGlyph(Matrix textRenderingMatrix,
                         PDFont font,
                         int code,
                         String unicode,
                         Vector displacement)
                  throws IOException

This method was originally written by Ben Litchfield for PDFStreamEngine.

Overrides:

showGlyph in class PDFStreamEngine

Parameters:

textRenderingMatrix - the current text rendering matrix, T_rm

font - the current font

code - internal PDF character code for the glyph

unicode - the Unicode text for this glyph, or null if the PDF does provide it

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

Throws:

IOException - if the glyph cannot be processed
