DO NOT REPLY [Bug 45391] New: Line dimensions are not proper when read from a PPT

https://issues.apache.org/bugzilla/show_bug.cgi?id=45391

           Summary: Line dimensions are not proper when read from a PPT
           Product: POI
           Version: unspecified
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: HSLF
        AssignedTo: dev@...
        ReportedBy: vinu.kumar@...

Sampe ppt for the bug

Following code is for reading a line in the ppt and converting to a graphics
object.

// Read all shapes
...

if  (type == ShapeTypes.Line)
{
  Line l = (Line)s;
  Rectangle a = l.getAnchor();
  int w = a.width;
  int h = a.height;
  double x = a.getX();
  double y = a.getY();

  BufferedImage img = new BufferedImage(w,h,BufferedImage.TYPE_INT_RGB);
  Graphics2D g = img.createGraphics();
  l.draw(graphics);
  // ... Draw the image

}

The issue is the height and width returned from anchor is smaller that actual
size.

If a ppt has a table, the table is drawn half.

Anchor doesn't take into account the line width.
If you want to draw individual lines you need to set the image dimensions
as max(linewidth, anchor.width) and max(linewidth, anchor.height):

   Rectangle2D a = l.getAnchor2D();
   double w = Math.max(a.getWidth(), l.getLineWidth());
   double h = Math.max(a.getHeight(), l.getLineWidth());

   BufferedImage img = new BufferedImage((int) Math.round(w), (int)
Math.round(h), BufferedImage.TYPE_INT_RGB);

Regards,
Yegor
