winJS(CameraCaptureUI)如何预览(完成)并将(?)图片保存到磁盘?
我做了很多研究,尝试了很多不起作用的东西。 所以我需要的是:winJS(CameraCaptureUI)如何预览(完成)并将(?)图片保存到磁盘?,camera,windows-runtime,windows-8.1,winjs,Camera,Windows Runtime,Windows 8.1,Winjs,我做了很多研究,尝试了很多不起作用的东西。 所以我需要的是: 获取图片(工作) 显示为用户预览(工作) 在图片库中创建图像(工作) 将预览作为该图像保存到本地图片文件夹(缺少) 谢谢 我捕获一张图片并将其显示在页面上,如下所示: function captureImage() { //S1: Create a new Camera Capture UI Object var cam = Windows.Media.Capture.CameraCaptureUI(); var n
function captureImage()
{
//S1: Create a new Camera Capture UI Object
var cam = Windows.Media.Capture.CameraCaptureUI();
var name = document.getElementById('ticketnum').innerHTML+'.jpg';
var folder = Windows.Storage.KnownFolders.picturesLibrary; //was windows.storage
//S2: Perform an Async operation where the Capture
// Image will be stored as file
cam.captureFileAsync(Windows.Media.Capture.CameraCaptureUIMode.photo)
.done(function (data) {
if (data)
{
//S3: Create a URL for the capture image
// and assign it to the <Img>
var urlpic= window.URL.createObjectURL(data);
document.getElementById('imgCapture').src
= urlpic;
//**save picture to memory as ticket number, creating new img, how to put the file inside?
folder.createFileAsync(name, Windows.Storage.CreationCollisionOption.replaceExisting) //creates new file?
.then(function (file) {
//file.copyAndReplaceAsync(window.URL.createObjectURL(data));
// HOW TO SAVE IMAGE TO pictures library?
});
}
}
, error);
document.getElementById('txtserver').value = "Done";
//save image to memory?
//clean up resources
}
函数captureImage()
{
//S1:创建一个新的摄影机捕获UI对象
var cam=Windows.Media.Capture.CameraCaptureUI();
var name=document.getElementById('ticketnum').innerHTML+'.jpg';
var folder=Windows.Storage.KnownFolders.picturesLibrary;//是Windows.Storage
//S2:执行异步操作,其中捕获
//图像将作为文件存储
cam.captureFileAsync(Windows.Media.Capture.CameraCaptureUIMode.photo)
.完成(功能(数据){
如果(数据)
{
//S3:为捕获图像创建URL
//并将其分配给以下是答案:
function testSavePictureDisk() {
// S1: Create a new Camera Capture UI Object
var cam = Windows.Media.Capture.CameraCaptureUI();
//location?
var name = document.getElementById('ticketnum').innerHTML + '.jpg';
var folder = Windows.Storage.KnownFolders.picturesLibrary; //was windows.storage
// S2: Perform an Async operation where the Capture
// Image will be stored as file
folder.createFileAsync(name,
Windows.Storage.CreationCollisionOption.replaceExisting) //creates new file?
.then(function (file) {
cam.captureFileAsync(Windows.Media.Capture.CameraCaptureUIMode.photo)
.done(function (data) {
if (data) {
//S3: Create a URL for the capture image
// and assign it to the <Img>
document.getElementById('imgCapture').src = window.URL.createObjectURL(data);
//**save picture to memory as ticket number
data.moveAndReplaceAsync(file);
//**end testing for local save
}
}
, error);
document.getElementById('txtserver').value = "Done";
//save image to memory?
//clean up resources
});//end of new file creation
}
函数testSavePictureDisk(){
//S1:创建一个新的摄影机捕获UI对象
var cam=Windows.Media.Capture.CameraCaptureUI();
//地点?
var name=document.getElementById('ticketnum').innerHTML+'.jpg';
var folder=Windows.Storage.KnownFolders.picturesLibrary;//是Windows.Storage
//S2:执行异步操作,其中捕获
//图像将作为文件存储
folder.createFileAsync(名称,
Windows.Storage.CreationCollisionOption.replaceExisting)//是否创建新文件?
.then(函数(文件){
cam.captureFileAsync(Windows.Media.Capture.CameraCaptureUIMode.photo)
.完成(功能(数据){
如果(数据){
//S3:为捕获图像创建URL
//并将其分配给
台阶
创建新文件
捕获一张图片并预览它
将图片移动到文件
是的,您发现从捕获中返回的“数据”变量是一个StorageFile对象,如果查看其属性,您将看到camera capture在您的temp appdata位置创建了一个文件。因此,您可以使用其moveAsync或MoveAndResplaceAsync方法将其传输到另一个位置。
