Constructor Details

DrawPrintTextLocations

public DrawPrintTextLocations(PDDocument document,
 String filename)
                       throws IOException

Instantiate a new PDFTextStripper object.

Parameters:

document -

filename -

Throws:

IOException - If there is an error loading the properties.

Method Details

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.

showGlyph

protected void showGlyph(Matrix textRenderingMatrix,
 PDFont font,
 int code,
 Vector displacement)
                  throws 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:

IOException - if the glyph cannot be processed

calculateGlyphBounds

private Shape calculateGlyphBounds(Matrix textRenderingMatrix,
 PDFont font,
 int code)
                            throws IOException

Throws:

IOException

stripPage

private void stripPage(int page)
                throws IOException

Throws:

IOException

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.
