Class LocationAwareTextExtractingPdfContentRenderListener.LocationOnPage

java.lang.Object
  com.itextpdf.text.pdf.parser.LocationAwareTextExtractingPdfContentRenderListener.LocationOnPage

All Implemented Interfaces:

Comparable<LocationAwareTextExtractingPdfContentRenderListener.LocationOnPage>

Enclosing class:

LocationAwareTextExtractingPdfContentRenderListener

private static class LocationAwareTextExtractingPdfContentRenderListener.LocationOnPage
extends Object
implements Comparable<LocationAwareTextExtractingPdfContentRenderListener.LocationOnPage>

Represents a chunk of text, it's orientation, and location relative to the orientation vector

Field Summary

(package private) int	distParallel parallel distance to the orientation unit vector (i.e.
(package private) int	distPerpendicular perpendicular distance to the orientation unit vector (i.e.
(package private) Vector	endLocation the ending location of the chunk
(package private) int	orientationMagnitude the magnitude of the orientation - this consists of just the Y component of the orientation vector this seems to work for now, but we may need to move to a different mechanism once we run into PDFs with different text orientation (This is just not an area that's been tested yet)
(package private) Vector	orientationVector unit vector in the orientation of the chunk
(package private) Vector	startLocation the starting location of the chunk
(package private) String	text the text of the chunk

Constructor Summary

LocationAwareTextExtractingPdfContentRenderListener.LocationOnPage(String string, Vector startLocation, Vector endLocation)

Method Summary

private static int	compareInts(int int1, int int2)
int	compareTo(LocationAwareTextExtractingPdfContentRenderListener.LocationOnPage rhs) Compares based on orientation, perpendicular distance, then parallel distance
private void	printDiagnostics()
boolean	sameLine(LocationAwareTextExtractingPdfContentRenderListener.LocationOnPage as)

Field Detail

text

final String text

the text of the chunk

startLocation

final Vector startLocation

the starting location of the chunk

endLocation

final Vector endLocation

the ending location of the chunk

orientationVector

final Vector orientationVector

unit vector in the orientation of the chunk

orientationMagnitude

final int orientationMagnitude

the magnitude of the orientation - this consists of just the Y component of the orientation vector this seems to work for now, but we may need to move to a different mechanism once we run into PDFs with different text orientation (This is just not an area that's been tested yet)

distPerpendicular

final int distPerpendicular

perpendicular distance to the orientation unit vector (i.e. the Y position in an unrotated coordinate system)

distParallel

final int distParallel

parallel distance to the orientation unit vector (i.e. the X position in an unrotated coordinate system
