Wolfgang Fahl commented on PDFBOX-4054:
---------------------------------------
[poppler][1]'s
pdftotext -bbox-layout
will create xhtml which has a
flow/block/line/word
structure e.g.
<flow>
<block xMin="333.000000" yMin="270.150000" xMax="360.004000"
yMax="275.150000">
<line xMin="333.000000" yMin="270.150000" xMax="360.004000"
yMax="275.150000">
<word xMin="333.000000" yMin="270.150000" xMax="342.896500"
yMax="275.150000">Your</word>
<word xMin="347.047500" yMin="270.150000" xMax="360.004000"
yMax="275.150000">Bank</word>
</line>
</block>
</flow>
You can select the details e.g. with [xmlstarlet][2]
xmlstarlet sel \
-N x="http://www.w3.org/1999/xhtml"; \
-t \
-m "//x:word" \
-v "concat(.,'-',./@xMin,'-',./@yMin,'-',./@xMax,'-',./@yMax)" \
-n \
input.html
which will give you the words and positions line by line. Just modify these
things to your need.
Your-333.000000-270.150000-343.503500-275.150000
Bank-347.707500-271.150000-360.991000-276.150000

> Key: PDFBOX-4054
> URL: https://issues.apache.org/jira/browse/PDFBOX-4054
> Project: PDFBox
> Issue Type: Improvement
> Affects Versions: 1.8.13
> Environment: any
> Reporter: Wolfgang Fahl
> Priority: Critical

> https://stackoverflow.com/questions/25109969/how-to-extract-a-paragraph-from-a-pdf-file-and-store-its-position/48119163?noredirect=1#comment83218312_48119163
> describes a need that pdftotext -bbox-layout fulfills by supplying structural
> information
> for the text extraction.
> There has been no PDFBox answer for a while so I assume such a feature is
> missing.
> A similar approach would be a useful improvement ot PDFBox and much wanted
> for certain applications - e.g. when the position of a text on a page is
> important for it's meaning.
> The poppler xhtml approach supplies for example:
> <flow>
> <block xMin="333.000000" yMin="270.150000" xMax="360.004000"
> yMax="275.150000">
> <line xMin="333.000000" yMin="270.150000" xMax="360.004000"
> yMax="275.150000">
> <word xMin="333.000000" yMin="270.150000" xMax="342.896500"
> yMax="275.150000">Your</word>
> <word xMin="347.047500" yMin="270.150000" xMax="360.004000"
> yMax="275.150000">Bank</word>
> </line>
> </block>
> </flow>
> flow/block/line/word is a hierachy and you get position information for block
> and line.
> PdfBox could supply similar information via callbacks.
