我正在用JAVA编写ESRI几何压缩算法,我用这个link。JAVA中的ESRI几何压缩算法
使用中提供的链接提到的指令,这是我的当前代码:
public static void main(String[] args) {
String dirPoints = "-118.356654545455,34.1146;-118.356436363636,34.1143272727273;-118.356418181818,34.1142363636364;-118.356490909091,34.1137636363636";
String compressedGeometry = "";
double xPointPrev = 0.0;
double yPointPrev = 0.0;
int coefficient = 55000;
String coefficient_32 = Integer.toString(coefficient, 32);
compressedGeometry = coefficient_32 + compressedGeometry;
String[] path_XY = dirPoints.split(";");
for (int i = 0, leni = path_XY.length; i < leni; i++) {
String[] xy = path_XY[i].split(",");
double pointX = Double.parseDouble(xy[0].trim());
double pointY = Double.parseDouble(xy[1].trim());
int xDifference = (int) Math.round(coefficient * (pointX - xPointPrev));
int yDifference = (int) Math.round(coefficient * (pointY - yPointPrev));
String xDifference_32 = Integer.toString(xDifference, 32);
compressedGeometry += xDifference_32;
String yDifference_32 = Integer.toString(yDifference, 32);
compressedGeometry += yDifference_32;
xPointPrev = pointX;
yPointPrev = pointY;
}
System.out.println(compressedGeometry);
}
预期输出: “+ 1lmo-66l1f + 1p8af + C-F + 1-5-4-Q”
但我得到这个:“1lmo-66l1g1p8afc-f1-5-4-q”
我错过了什么?任何帮助,高度赞赏。 谢谢,
谢谢,我的问题现在解决了。 –
