public final class EscherGraphics2d
extends java.awt.Graphics2D
Important:
One important concept worth considering is that of font size. One of the difficulties in converting Graphics calls into escher drawing calls is that Excel does not have the concept of absolute pixel positions. It measures it's cell widths in 'characters' and the cell heights in points. Unfortunately it's not defined exactly what a type of character it's measuring. Presumably this is due to the fact that the Excel will be using different fonts on different platforms or even within the same platform.Because of this constraint you have to calculate the verticalPointsPerPixel. This the amount the font should be scaled by when you issue commands such as drawString(). A good way to calculate this is to use the follow formula:
multipler = groupHeightInPoints / heightOfGroupThe height of the group is calculated fairly simply by calculating the difference between the y coordinates of the bounding box of the shape. The height of the group can be calculated by using a convenience called
HSSFClientAnchor.getAnchorHeightInPoints()
.

public void fillPolygon(int[] xPoints, int[] yPoints, int nPoints)
This draws the polygon, with nPoint
line segments.
The first nPoint - 1
line segments are
drawn between sequential points
(xPoints[i],yPoints[i],xPoints[i+1],yPoints[i+1]
).
The final line segment is a closing one, from the last point to
the first (assuming they are different).
The area inside of the polygon is defined by using an even-odd fill rule (also known as the alternating rule), and the area inside of it is filled.
