[jira] Created: (PDFBOX-583) TextPosition#getIndividualWidths
returns negative values
TextPosition#getIndividualWidths returns negative values
--------------------------------------------------------
Key: PDFBOX-583
URL: https://issues.apache.org/jira/browse/PDFBOX-583
Project: PDFBox
Issue Type: Bug
Components: Text extraction, Utilities
Affects Versions: 1.0.0
Reporter: Villu Ruusmann
Priority: Critical
I was notified by Peter Costello (peterwcostello at gmail dot com) that there has been a regression in PDFStreamSource, which results in TextPosition returning negative individual character widths. This could happen, because I only tested with TextPosition#getWidth(), but not with TextPosition#getIndividualWidths(). Below is the original message:
Bug introduced to /pdfbox/trunk/src/main/java/org/apache/pdfbox/util/PDFStreamEngine.java on revision 885904
Line 422 changed to:
float widthText = glyphMatrixStDisp.getXPosition() - glyphMatrixEndDisp.getXPosition();
Polarity of width now negative. Should be
float widthText = glyphMatrixEndDisp.getXPosition() - glyphMatrixStDisp.getXPosition();
