------------------------------------
Summary: PDFTextStripper groups unrelated chunks into words
Key: PDFBOX-4313
URL: https://issues.apache.org/jira/browse/PDFBOX-4313
Project: PDFBox
Issue Type: Bug
Components: Text extraction
Affects Versions: 2.0.11
Reporter: Emilian Bold
I have the text "10" and "11" and they get merged into to "1110" word.
Coordinates are:
1 575.36 x 227.4 w 4.447998 h 5.736
1 579.752 x 227.4 w 4.447998 h 5.736
1 526.2 x 227.4 w 4.447998 h 5.736
0 530.59204 x 227.4 w 4.447998 h 5.736
The bug is in in this chunk:
{{{
// test if our TextPosition starts after a new word would be
expected to start
if (expectedStartOfNextWordX !=
EXPECTED_START_OF_NEXT_WORD_X_RESET_VALUE
&& expectedStartOfNextWordX < positionX &&
// only bother adding a space if the last character
was not a space
lastPosition.getTextPosition().getUnicode() != null
&&
!lastPosition.getTextPosition().getUnicode().endsWith(" "))
{
line.add(LineItem.getWordSeparator());
}
}}}
which seems to add a word separator only if the next char is "after" the
current word. It never expects that the next char might be "before" the current
word.
I guess this could also be framed as a RTL problem, but the PDF is a plain PDF,
it just seems that Oracle Reports generates these chunks in the reverse order.
