--------------------------------------
Summary: Text extraction reports zero character widths
Key: PDFBOX-2584
URL: https://issues.apache.org/jira/browse/PDFBOX-2584
Project: PDFBox
Issue Type: Bug
Components: Text extraction
Affects Versions: 1.8.8, 2.0.0
Reporter: Pavel Misurkin
We are using PDFBox API to get position of characters within a document
Have found a problem with one document:: text extraction properly extracting
text but set all character's width to zero
Code is pretty simple
{code}
File input = new File("stip_2c.pdf");
document = PDDocument.load(input);
PDFTextStripper extractor = new PDFTextStripper();
Writer output = new StringWriter();
extractor.writeText(document, output);
{code}
We are examining then value of Extractor.charactersByArticle member for
characters widths
- Have found the issue in 1.8.4
all chars widths were == zero
- in version 1.8.8
all chars widths were == zero except whitespaces.
See new validation added in 1.8.8

{code} if (spaceWidthText == 0)
{
spaceWidthText = 1.0f; // if could not find font, use a generic
value
} {code}
- in version 2.0.0 problem still exists
