[jira] [Commented] (PDFBOX-1201) PDFTextStripperByArea y coordinate shifted "up"

["Ilija Pavlic (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PDFBOX-1201?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13179954#comment-13179954 ] 

Ilija Pavlic commented on PDFBOX-1201:
--------------------------------------

Manually shifting the region considerably lower still misses the lines even though they are generously covered by the cyan rectangle. Defining the region to start (x, 0f, width, height) captures the region.

> 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.

> Rectangle2D.Float region = new Rectangle2D.Float(x, y, width, height);

> // 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);

> 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.
