Andreas Meier commented on PDFBOX-2252:
---------------------------------------
I want provide a new patch to address this Problem, unfortunately the
layout/format of my code is different than the one in the pdfbox svn trunk. I
have already added and activated pdfbox-eclipse-formatter.xml to my IDE, but I
am still missing something.
Is there a cleanup configuration or some other formatting configuration I
missed?
Example:
{code:title=PDFTextStripper.java|borderStyle=solid}
/**
* a list of regular expressions that match commonly used
* list item formats, i.e. bullets, numbers, letters,
* Roman numerals, etc. Not meant to be
* comprehensive.
*/
private static final String[] LIST_ITEM_EXPRESSIONS = {
"\\.",
"\\d+\\.",
"\\[\\d+\\]",
"\\d+\\)",
"[A-Z]\\.",
"[a-z]\\.",
"[A-Z]\\)",
"[a-z]\\)",
"[IVXL]+\\.",
"[ivxl]+\\.",
};
{code}
is formatted to sth. like that:
{code:title=PDFTextStripper.java|borderStyle=solid}
/**
* a list of regular expressions that match commonly used list item formats,
i.e. bullets, numbers, letters,
* Roman numerals, etc. Not meant to be comprehensive.
*/
private static final String[] LIST_ITEM_EXPRESSIONS = { "\\.", "\\d+\\.",
"\\[\\d+\\]",
"\\d+\\)", "[A-Z]\\.", "[a-z]\\.", "[A-Z]\\)", "[a-z]\\)",
"[IVXL]+\\.", "[ivxl]+\\.", };
{code}

> Key: PDFBOX-2252
> URL: https://issues.apache.org/jira/browse/PDFBOX-2252
> Project: PDFBox
> Issue Type: Bug
> Components: Text extraction
> Affects Versions: 1.8.6, 2.0.0
> Reporter: Amir
> Priority: Critical
> Fix For: 2.1.0
>
> Attachments: PDFTextStripper.java.patch, atest.pdf, overlap.jpg,
> test.pdf, wikipedia_dl_lyric_test.pdf
>
>
> When the input document of PDFTextStripper is a combination of right-to-left
> and left-to-right languages, the output characters of one language is
> reversed.
> A sample bilingual pdf document is attached.
> PDFTextStripper has a variable "isRtlDominant" in "writePage" function, which
> is defined as follows: boolean isRtlDominant = rtlCount > ltrCount;
> This class clearly count the number of rtl characters and decide if the whole
> content should be revered or not. It's not true, it must operate on each
> word, not the whole document.
