Upload a photo from iPhone camera with PhoneGap
Getting a photo from an iPhone camera to the internet is the first step in any photo-sharing app. Here is a snippet of code using PhoneGap that uploads a photo from an iPhone to a webserver.
function onBodyLoad()
{
document.addEventListener(“deviceready”,onDeviceReady,false);
}
function onDeviceReady()
{
try{
navigator.camera.getPicture(onCaptureSuccess, onCaptureFail);
}
catch(ex)
{
alert(ex);
}
}
function onCaptureSuccess(imageURI)
{
try
{
$.ajax({
type: “POST”,
url: “http://distance.freetextuk.com/upload.aspx”,
data: { image: imageURI}
}).done(function( msg ) {
$(“#imgLoad”).attr(“src”,”http://yourserver.com/uploads/” + msg);
}).fail(function(a,b){
alert( “Failed to save:” + b);
});
}
catch(ex)
{
alert(ex);
}
}
function onCaptureFail()
{
alert(“Failed to capture!”);
}
protected void Page_Load(object sender, EventArgs e)
{
string strImage = Request.Form[“Image”];
if (string.IsNullOrEmpty(strImage))
{
Response.Write(“Image field not provided”);
return;
}
byte[] b = System.Convert.FromBase64String(strImage);
var strRealPath = Server.MapPath(“~/uploads/”);
var strRandomFile = System.IO.Path.GetRandomFileName() + “.jpg”;
FileStream fs = new FileStream(strRealPath + strRandomFile, FileMode.CreateNew);
fs.Write(b, 0, b.Length);
fs.Close();
Response.Write(strRandomFile);
}
Note, that you will need to create an “uploads” folder, and give this folder write permissions.
Network Programming in .NET 
I want to capture an image in a Phonegap app, then I send it to a remote server with web service. net.
I use the webService :
[WebMethod]
public bool SavePhoto(Guid IdPrestation, Guid IdPhoto, byte[] ImgIn)
{
System.IO.MemoryStream ms = new System.IO.MemoryStream(ImgIn);
System.Drawing.Bitmap b =(System.Drawing.Bitmap)System.Drawing.Image.FromStream(ms);
//Si le repertoire n’existe pas alors on le crée
// if (! RepertoirePhotoExist(IdPrestation))
//{
System.IO.Directory.CreateDirectory(HttpContext.Current.Server.MapPath(“Photos/” + IdPrestation.ToString()));
//}
string strFichier = HttpContext.Current.Server.MapPath(“Photos/” + IdPrestation.ToString() + “/” + IdPhoto.ToString() + “.jpg”);
// Si le fichier existe alors
if (System.IO.File.Exists(strFichier))
{
System.IO.File.Delete(strFichier);
}
else
{
b.Save(strFichier, System.Drawing.Imaging.ImageFormat.Jpeg);
}
return true;
}
please help.
