示例1: drawOneKey
import ij.process.ImageProcessor; //導入方法依賴的package包/類
void drawOneKey(SiftKeypoint key, ImageProcessor ip) {
double x = (int) Math.rint(key.x);
double y = (int) Math.rint(key.y);
int u0 = (int) x;
int v0 = (int) y;
double phi = key.orientation;
double scale = key.scale;
double dx = magnification * scale * Math.cos(phi);
double dy = magnification * scale * Math.sin(phi); // NOTE: angle runs reversed
int u1 = (int) Math.rint(x + dx);
int v1 = (int) Math.rint(y + dy);
ip.setColor(boxColor);
ip.drawRect(u0-1, v0-1, 3, 3);
ip.setColor(lineColor);
ip.drawLine(u0,v0,u1,v1);
}
