Question

设置correctOrientation：true，然后解决图像旋转问题并设置缩略图 - 但图像路径为：file：//storage/emulated/0/Android/data/com.examole.helloworld/modified.jpg？149028394994

如果没有correctOrientation：true，则图像路径为：file：///storage/emulated/0/DCIM/Camera/1490345556009.jpg

尝试使用correctOrientation设置另一个图像时：true，则不会设置最新选择的图像。以下是您的参考代码：

navigator.camera.getPicture(captureSuccess, onFail, {quality: 50,
        destinationType: Camera.DestinationType.FILE_URI,
        sourceType: Camera.PictureSourceType.SAVEDPHOTOALBUM,
        mediaType: Camera.MediaType.PICTURE,
        correctOrientation: true,
        allowEdit: true
 });

先谢谢。

Answer 1

You can try this,      

  $(document).on('click','.capture_photo',function(){
                navigator.camera.getPicture(onPhotoDataSuccess, onFail, {
                  quality : 75,
                  destinationType : Camera.DestinationType.DATA_URL,
                  sourceType : Camera.PictureSourceType.CAMERA,
                  encodingType: Camera.EncodingType.PNG,
                  popoverOptions: CameraPopoverOptions,
                  saveToPhotoAlbum: false 
                });
            }); 
        // to call the success function of capture image(onPhotoDataSuccess)
             function onPhotoDataSuccess(imageData) { 
              sessionStorage.setItem("img_api",imageData);
              $('#captureimg').attr('src','data:image/jpeg;base64,' + imageData);
                App.show_toast("Profile image updated successfully!");
            }
       //onfail
    onFail(message) { alert('Failed because: ' + message); }

Answer 2

我已经解决了这个并发布了我的答案

navigator.camera.getPicture(captureSuccess, onFail, {quality: 50,
        destinationType: Camera.DestinationType.FILE_URI,
        sourceType: Camera.PictureSourceType.SAVEDPHOTOALBUM,
        mediaType: Camera.MediaType.PICTURE,
        correctOrientation: true,
});

var captureSuccess = function(mediaFiles) {
     var fD = mediaFiles;
     window.resolveLocalFileSystemURI(fD, function(fileEntry) {
       fileEntry.file(function(fT) {
         var fname = fileEntry.nativeURL.substr(fileEntry.nativeURL.lastIndexOf('/') + 1);
         fileTransferUpload(fD,fname);
       }, function() {
       console.log('error');
       });
    }, onFError);
};

上面的方法fileTransferUpload只会在src中设置图像路径。

成功回调函数，接收到图像路径，并且没有从此路径获取nativeURL，我已在src中设置路径本身。

这是一个更好的解决方案（涉及挖掘一些Java文件，但需要大约8秒）

在CameraLauncher.java中（在cordova-plugin-camera / src / android文件夹中）

//Old:
String modifiedPath = getTempDirectoryPath() + "/modified"+".jpg";
this.callbackContext.success("file://" + modifiedPath + "?" + System.currentTimeMillis());

AKA只是在文件名中移动时间戳。

//New:    
String modifiedPath = getTempDirectoryPath() + "/modified"+  System.currentTimeMillis() +".jpg";
this.callbackContext.success("file://" + modifiedPath);

Answer 4

document.addEventListener("deviceready",onDeviceReady,false);
    var pictureSource;   // picture source
    var destinationType; // sets the format of returned value
    function onDeviceReady() {
        pictureSource=navigator.camera.PictureSourceType;
        destinationType=navigator.camera.DestinationType;
    }

抱歉，您想要添加此代码。
