[jira] [Created] (PDFBOX-1201) PDFTextStripperByArea y coordinate
shifted "up"
PDFTextStripperByArea y coordinate shifted "up"
-----------------------------------------------
Key: PDFBOX-1201
URL: https://issues.apache.org/jira/browse/PDFBOX-1201
Project: PDFBox
Issue Type: Bug
Components: Text extraction
Affects Versions: 1.6.0
Reporter: Ilija Pavlic
Priority: Minor
The text stripper region seems to be shifted up from the given coordinates, causing lines below the region to be included and ones above the defined region to be included.
...
PDPage page = (PDPage) allPages.get(0);
PDFTextStripperByArea stripper = new PDFTextStripperByArea();
Rectangle2D.Float region = new Rectangle2D.Float(x, y, width, height);
stripper.addRegion("test region", region);
// overlay the region with a cyan rectangle to check if I got the coordinates and dimensions right
PDPageContentStream contentStream = new PDPageContentStream(document, page, true, true);
contentStream.setNonStrokingColor( Color.CYAN );
contentStream.fillRect(x, y, width, height);
contentStream.close();
stripper.extractRegions(page);
String content = stripper.getTextForRegion("test region");
...
document.save(...);
...
The cyan rectangle overlays the desired region exactly when viewing the saved output document. On the other hand, stripper misses a couple of lines at the bottom of the rectangle and includes couple of lines above the rectangle.

(was: It seems like the missed text is part of the larger text box that starts and ends outside the capture region but the text itself is located inside the capture region. )
