I mean this part:
{code}
BoundingBox bbox = font.getBoundingBox();
if (bbox.getLowerLeftY() < Short.MIN_VALUE)
{
// PDFBOX-2158 and PDFBOX-3130
// files by Salmat eSolutions / ClibPDF Library
bbox.setLowerLeftY(- (bbox.getLowerLeftY() + 65536));
}
// 1/2 the bbox is used as the height todo: why?
float glyphHeight = bbox.getHeight() / 2;
// sometimes the bbox has very high values, but CapHeight is OK
PDFontDescriptor fontDescriptor = font.getFontDescriptor();
if (fontDescriptor != null)
{
float capHeight = fontDescriptor.getCapHeight();
if (capHeight != 0 && (capHeight < glyphHeight || glyphHeight == 0))
{
glyphHeight = capHeight;
}
}
{code}
That should somehow be replaced with some of the code from
DrawPrintLocations.calculateGlyphBounds() to get a {{glyphHeight}}.

> Project: PDFBox
> Issue Type: Bug
> Components: Text extraction
> Affects Versions: 2.0.7
> Environment: Operating system: Windows 7 (64 bit).
> Reporter: Navnath Kumbhar
> Labels: how-to

> Hello Support Team,
> I am working on a project which parses a whole PDF document and stores the
> extracted text in some .txt file which can be read by other product.
> My issue is regarding extracting the text inside the cell of a table:
> *x,y co-ordinates of the text inside the cell are not getting correctly.*
> Y value of the last text line in the cell is getting larger than cell's max-Y
> value.
> I have attached the test file with this bug.
> As you can see in the test document, there is one cell along-with text in it
> and a text paragraph next to that cell.
> x-y coordinates that I get from pdfbox for all the paths (two vertical and
> two horizontal lines) of the cell are:
> (in x1,y1,x2,y2 format)
> Horizontal line 1: [100,88,220,88]
> Horizontal line 2: [100,120,220,120]
> Vertical line 1 : [100,88,100,120]
> Vertical line 2: [220,88,220,120]
> (Y values of the above paths are final values by subtracting the actual value
> given by pdfbox from height of the page as I see that for paths, y-values are
> processed from bottom to up)
> And bounding box of the last line in that cell is : [102,114,59,7] and hence
> max-Y of that line becomes 121 (min-Y + height)
>
> So, if we consider max-Y value of that cell (i.e. 120) and that of last line
> in that cell (i.e. 121), clearly, that line goes out of that cell.
> What can be the possible reason for this?
> Thank you in advance!
> Regards,
> Navnath Kumbhar
