The translation is lossy so * many features are not supported and some just aren't implemented yet. If * in doubt test the specific calls you wish to make. Graphics calls are * always performed into an EscherGroup so one will need to be created. * <p> * <b>Important:</b> * <blockquote> * 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. * <p> * Because of this constraint we've had 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: * <pre>{@code * multiplier = groupHeightInPoints / heightOfGroup * }</pre> * <p> * The 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 * {@code HSSFClientAnchor.getAnchorHeightInPoints()}. * </blockquote> */ public class EscherGraphics extends Graphics { private static final Logger LOG = LogManager.getLogger(EscherGraphics.class); private final HSSFShapeGroup escherGroup; private final HSSFWorkbook workbook; private final float verticalPointsPerPixel; private final float verticalPixelsPerPoint; private Color foreground; private Color background = Color.white; private Font font; /** * Construct an escher graphics object. * * @param escherGroup The escher group to write the graphics calls into. * @param workbook The workbook we are using. * @param forecolor The foreground color to use as default. * @param verticalPointsPerPixel The font multiplier.
