I need to set image source dynamically, please note my image is in somewhere on the Network, here is my code
BitmapImage logo = new BitmapImage();
logo.BeginInit();
logo.UriSource = new Uri(#"pack://application:,,,\\myserver\\folder1\\Customer Data\\sample.png");
logo.EndInit(); // Getting the exception here
ImageViewer1.Source = logo;
Exception:
The URI prefix is not recognized
None of the above solutions worked for me. But this did:
myImage.Source = new BitmapImage(new Uri(#"/Images/foo.png", UriKind.Relative));
You just need one line:
ImageViewer1.Source = new BitmapImage(new Uri(#"\myserver\folder1\Customer Data\sample.png"));
The pack syntax you are using here is for an image that is contained as a Resource within your application, not for a loose file in the file system.
You simply want to pass the actual path to the UriSource:
logo.UriSource = new Uri(#"\\myserver\folder1\Customer Data\sample.png");
None of the methods worked for me as i needed to pull the image from a folder instead of adding it to the application.
The below code worked:
TestImage.Source = GetImage("/Content/Images/test.png")
private static BitmapImage GetImage(string imageUri)
{
var bitmapImage = new BitmapImage();
bitmapImage.BeginInit();
bitmapImage.UriSource = new Uri("pack://siteoforigin:,,,/" + imageUri, UriKind.RelativeOrAbsolute);
bitmapImage.EndInit();
return bitmapImage;
}
You are all wrong!
Why? Because all you need is this code to work:
(image View) / C# Img is : your Image box
Keep this as is, without change ("ms-appx:///) this is code not your app name
Images is your folder in your project you can change it.
dog.png is your file in your folder, as well as i do my folder 'Images' and file 'dog.png'
So the uri is :"ms-appx:///Images/dog.png"
and my code :
private void Button_Click(object sender, RoutedEventArgs e)
{
img.Source = new BitmapImage(new Uri("ms-appx:///Images/dog.png"));
}

I have a picture in the resources that I have been loading using the following code:
var path = new Uri("pack://application:,,,/DocumentHandlingTouch;component/Resources/pdf.jpg", UriKind.Absolute);
My computer crashed in between builds and now it doesn;t load that picture onto the canvas at all any more.
Any Ideas?
Please check if you have set the build action of the image files to 'Resource' in your project.
var pdfimage = new Image();
BitmapImage src = new BitmapImage();
src.BeginInit();
src.UriSource = new Uri(#"pack://application:,,,/DocumentHandlingTouch;component/Resources/pdf.jpg", UriKind.Absolute);
src.EndInit();
pdfimage.Source = src;
I want to save am image from [URL : https://www.example.com/folders/file.jpg][1]
in an object of BitmapImage
I tried the following :
BitmapImage b = new BitmapImage();
b.SetSource(new Uri("https:www.example.com/folders/file.jpg", UriKind.RelativeOrAbsolute));
But its not working. Why?
This code test and work for me:
Image MyImage = new Image();
// Create source.
BitmapImage bImage = new BitmapImage();
bImage.UriSource = new Uri(#"https:www.example.com/folders/file.jpg", UriKind.RelativeOrAbsolute);
// Set the image source.
MyImage.Source = bImage;
Tell me if work for you or need more info. Good luck man!
I am trying to add Images to a GridView, but the images never actually show.
Instead, I'm just display the class name in a Thumbnail looking layout.
Here is the code that I have been tweaking
public async void setImage(string url) {
Byte[] imageBytes = await httpClient.GetByteArrayAsync(url);
MemoryStream stream = new MemoryStream(imageBytes);
var randomAccessStream = new MemoryRandomAccessStream(stream);
BitmapImage image = new BitmapImage();
await image.SetSourceAsync(randomAccessStream);
imagesGrid.Items.Add(image);
}
Thanks for the help. I ended up with the following block that works.
public void setImage(string url) {
Image img = new Image();
img.Source = new BitmapImage(new Uri(url));
imagesGrid.Items.Add(img);
}
This is because you're adding BitmapImages to your visual tree. BitmapImages are not visual elements. What you need to do is create an Image and set the Source property to the URI of your image file. There are a number of examples of this in xaml and also code on my blog here.
I haven't tested this but it should be something like this:
Image img = new Image();
img.Source = new BitmapImage(new Uri(url));
imagesGrid.Items.Add(img);
I am working on a Windows 8 app. I need to know how to programmatically set the Source of an Image. I assumed that the Silverlight approach would work. However, it doesn't. Does anybody know how to do this? The following will not work:
string pictureUrl = GetImageUrl();
Image image = new Image();
image.Source = new Windows.UI.Xaml.Media.Imaging.BitmapImage(new Uri(pictureUrl, UriKind.Relative));
image.Stretch = Stretch.None;
image.HorizontalAlignment = Windows.UI.Xaml.HorizontalAlignment.Left;
image.VerticalAlignment = Windows.UI.Xaml.VerticalAlignment.Center;
I get an Exception that says: "The given System.Uri cannot be converted into a Windows.Foundation.Uri."
However, I can't seem to find the Windows.Foundation.Uri type.
I just tried
Image.Source = new BitmapImage(
new Uri("http://yourdomain.com/image.jpg", UriKind.Absolute));
And it works without problems... I'm using System.Uri here. Maybe you have a malformed URI or you have to use an absolute URI and use UriKind.Absolute instead?
This is what I use:
string url = "ms-appx:///Assets/placeHolder.png";
image.Source = RandomAccessStreamReference.CreateFromUri(new Uri(url));
Well, Windows.Foundation.Uri is documented like this:
.NET: This type appears as System.Uri.
So the tricky bit isn't converting it into a Windows.Foundation.Uri yourself - it looks like WinRT does that for you. It looks like the problem is with the URI you're using. What is it relative to in this case? I suspect you really just need to find the right format for the URI.
This example uses a FileOpenPicker object to obtain the storage file.
You can use whatever method you need to access your file as a StorageFile object.
Logo is the name of the image control.
Reference the following code:
var fileOpenPicker = new FileOpenPicker();
fileOpenPicker.ViewMode = PickerViewMode.Thumbnail;
fileOpenPicker.SuggestedStartLocation = PickerLocationId.PicturesLibrary;
fileOpenPicker.FileTypeFilter.Add(".png");
fileOpenPicker.FileTypeFilter.Add(".jpg");
fileOpenPicker.FileTypeFilter.Add(".jpeg");
fileOpenPicker.FileTypeFilter.Add(".bmp");
var storageFile = await fileOpenPicker.PickSingleFileAsync();
if (storageFile != null)
{
// Ensure the stream is disposed once the image is loaded
using (IRandomAccessStream fileStream = await storageFile.OpenAsync(Windows.Storage.FileAccessMode.Read))
{
// Set the image source to the selected bitmap
BitmapImage bitmapImage = new BitmapImage();
await bitmapImage.SetSourceAsync(fileStream);
Logo.Source = bitmapImage;
}
}
check your pictureUrl since it was what resulted in the exception.
but this should work as well
img.Source = new BitmapImage(new Uri(pictureUrl, UriKind.Absolute));
it should have nothing to do with Windows.Foundation.Uri. since winrt will handle it for you.
Try this format:
ms-appx:/Images/800x600/BackgroundTile.bmp
The given System.Uri cannot be converted into a Windows.Foundation.Uri
<Image Name="Img" Stretch="UniformToFill" />
var file = await KnownFolders.PicturesLibrary.GetFileAsync("2.jpg");
using(var fileStream = (await file.OpenAsync(Windows.Storage.FileAccessMode.Read))){
var bitImg= new BitmapImage();
bitImg.SetSource(fileStream);
Img.Source = bitImg;
}
I'm trying to get all images from a directory in WP7. I already use
var temp = Directory.GetFiles(#"\Pictures");
but it doesn't seem to work.
by the way i also tried the isolated storage solution. but none of those solution seems to work.
Is i a wp7 limitation?
you shoud use following code for images from the resources:
Uri uri = new Uri(uriString, UriKind.Relative);
String originalUriString = uri.OriginalString;
Uri resourceStreamUri = originalUriString.StartsWith("/", StringComparison.Ordinal) ? new Uri(originalUriString.TrimStart('/'), UriKind.Relative) : uri;
StreamResourceInfo streamResourceInfo = Application.GetResourceStream(resourceStreamUri);
if (null != streamResourceInfo)
{
stream = streamResourceInfo.Stream;
BitmapImage bitmapImage = new BitmapImage();
bitmapImage.SetSource(stream);
Image image = new Image();
image.Source = bitmapImage;
}
Probably, you should use IsolatedStorageFile.GetFileNames instead.

You probalby have your pictures as Resource and not as Content. Right click on images in your solution and change the Build Action to Content.
