public void getStyleMetrics(float pointSize, float[] metrics, int offset)

The length of the metrics array must be >= offset+4, and offset must be >= 0. Typically offset is 4. This method will store the following elements in that array before returning: metrics[off+0]: strikethrough offset metrics[off+1]: strikethrough thickness metrics[off+2]: underline offset metrics[off+3]: underline thickness Note that this implementation simply returns default values; subclasses can override this method to provide more accurate values.
