Question

我正试图用棕褐色滤镜打印出一张照片，但它只打印了两次相同的（未经编辑的）照片。如何在底部使用我的棕褐色代码？代码将图片转换为灰度，然后是棕褐色。

import images.*;

public class Sepia{

 public static void main(String[]args){
  APImage image = new APImage("lobster.jpg");
  image.draw();
  APImage aCopy = image.clone();
  for (Pixel p: aCopy){
     int red = p.getRed();
     int green = p.getGreen();
     int blue = p.getBlue();
     int average = (red + green + blue) / 3;
     p.setRed(average);
     p.setGreen(average);
     p.setBlue(average);

     if (red < 63){
       red = (int)(red *1.1);
       blue = (int)(blue * 0.9);
     }else if (red < 192){
       red = (int)(red*1.15);
       blue = (int)(blue *0.85);
     }else{
       red = Math.min((int)(red*1.08),255);
       blue = (int)(blue *0.93);
     }

     aCopy.draw();
     aCopy.save();
   }
 }
}

在抽奖前尝试添加此内容。

    function calcDistance(origin1,destinationB){
        var geocoder = new google.maps.Geocoder();
        var service = new google.maps.DistanceMatrixService();
        var temp_duration = 0;
        var temp_distance = 0;
        var testres;
        service.getDistanceMatrix(
            {
                origins: [origin1],
                destinations: [destinationB],
                travelMode: google.maps.TravelMode.DRIVING,
                unitSystem: google.maps.UnitSystem.METRIC,
                avoidHighways: false,
                avoidTolls: false
            }, function(response, status) {
                if (status !== google.maps.DistanceMatrixStatus.OK) {
                    alert('Error was: ' + status);
                    testres= {"duration":0,"distance":0};
                } else {
                    var originList = response.originAddresses;
                    var destinationList = response.destinationAddresses;
                    var showGeocodedAddressOnMap = function (asDestination) {
                        testres= function (results, status) {
                        };
                    };
                    var duration_total;
                    for (var i = 0; i < originList.length; i++) {
                        var results = response.rows[i].elements;
                        geocoder.geocode({'address': originList[i]},
                            showGeocodedAddressOnMap(false));
                        for (var j = 0; j < results.length; j++) {
                            geocoder.geocode({'address': destinationList[j]},
                                showGeocodedAddressOnMap(true));
                            temp_duration+=results[j].duration.value;
                            temp_distance+=results[j].distance.value;
                        }
                    }
                    testres= {"duration":temp_duration,"distance":temp_distance};
                }
            }
        );
    }

    result = calcDistance(source,dest);
