Someone helped me get this code for taking a picture using xamarin forms labs camera:
picker = DependencyService.Get<IMediaPicker> ();
task = picker.TakePhotoAsync (new CameraMediaStorageOptions {
DefaultCamera = CameraDevice.Rear,
MaxPixelDimension = 800,
});
img.BackgroundColor = Color.Gray;
Device.StartTimer (TimeSpan.FromMilliseconds (250), () => {
if (task != null) {
if (task.Status == TaskStatus.RanToCompletion) {
Device.BeginInvokeOnMainThread (async () => {
//img.Source = ImageSource.FromStream (() => task.Result.Source);
var fileAccess = Resolver.Resolve<IFileAccess> ();
string imageName = "img_user_" + User.CurrentUser().id + "_" + DateTime.Now.ToString ("yy_MM_dd_HH_mm_ss") + ".jpg";
fileName = imageName;
fileAccess.WriteStream (imageName, task.Result.Source);
fileLocation = fileAccess.FullPath(imageName);
FileStream fileStream = new FileStream(fileAccess.FullPath(imageName), FileMode.Open, System.IO.FileAccess.Read);
imageUrl = (string)test[0]["url"];
img.Source = imageUrl;
});
}
return task.Status != TaskStatus.Canceled
&& task.Status != TaskStatus.Faulted
&& task.Status != TaskStatus.RanToCompletion;
}
return true;
});
It saves the image, but the actual size of the phone picture taken is huge, is there a way to resize it.
UPDATE: The original answer is not useful, see below for updated answer. The issue was the PCL library was very slow and consumed too much memory.
ORIGINAL ANSWER (do not use):
I found an image I/O library, ImageTools-PCL, which I forked on github and trimmed down what wouldn't compile in Xamarin, keeping the modifications to minimum and the result seems to work.
To use it download the linked repository, compile it with Xamarin and add the DLLs from
Build
folder to your Forms project.To resize an image you can do this (should fit the context of your question)
UPDATED ANSWER:
Get Xamarin.XLabs from nuget, learn about using Resolver, create an IImageService interface with
Resize
method.Implementation for iOS:
Implementation of the service for Android:
