I want to rotate an image with mouse. So mouse could be there any place not ine middle of the picture. How this can be done?
What is the bounding rect for the new rotated image.
Any help will be very much appreciated.
Best regards
Agha Khan
teichgraf has applied patch #17681.
Comment:
Added. Thanks! :)
var modifiedImage = WriteableBitmapExtensions.RotateFree(all[3], 30, false); writeableBmp.Blit(newRect(0, 0, 1000, 1000), modifiedImage, newRect(0, 0, 1000, 1000));Unfortunately there no no option where I could mention center of rotation and always rotates around center of image. Also I have now I have no idea of bounding Rect, so I placed very large Rect(0,0,1000,1000) , which is not ideal either.
WriteableBitmap wbmp = BitmapFactory.New(1, 1).FromByteArray(binary);
} // If the file path and name is entered properly, and user has not tapped 'cancel'..
if (file != null)
{
var property = await file.Properties.GetImagePropertiesAsync();
WriteableBitmap wb = new WriteableBitmap((int)property.Width, (int)property.Height);
using (IRandomAccessStream fileStream = await file.OpenAsync(Windows.Storage.FileAccessMode.Read))
{
await wb.SetSourceAsync(fileStream);
byte[] binaryImage = wb.ToByteArray();
Model.Client.Photos.Add(binaryImage);
}
}
The WriteableBitmapEx library is a collection of extension methods for the
WriteableBitmap. The WriteableBitmap class is available for all XAML flavors including Windows Phone, WPF, WinRT Windows Store XAML, (Windows 10) UWP and Silverlight. It allows the direct manipulation of a bitmap and can be used for image manipulation,
to generate fast procedural images by drawing directly to a bitmap and more.
The WriteableBitmap API is very minimalistic and there's only the raw
Pixels array for such operations. The WriteableBitmapEx library tries to compensate that with extensions methods that are easy to use like built in methods and offerGDI+ like functionality. The library extends the WriteableBitmap class with elementary and fast (2D drawing) functionality, conversion methods and functions to combine (blit) WriteableBitmaps.
The extension methods are grouped into different C# files using a partial class approach. It is possible to include just a few methods by using the specific source code files directly or the full functionality via the built binaries.
The latest binaries are always available as
NuGet package.
WriteableBitmapEx was also ported to Windows Embedded.
See the Issue Tracker for a list of features that will be added in the future.
GDI+ like drawing functionality for the WriteableBitmap.
Support for Windows Phone Silverlight, Windows Phone WinRT, desktop Silverlight, WPF, Windows 8/8.1 WinRT XAML and Windows 10 UWP.

The WriteableBitmapEx methods are much faster than the XAML Shape subclasses. For example, the WriteableBitmapEx line drawing approach is more than 20-30 times faster as the Silverlight Line element. So if a lot of shapes need to be drawn and anti-aliasing or other SIlverlight Shape properties are not needed, the WriteableBitmapEx methods are the right choice.

The WriteableBitmapEx library has its origin in several blog posts that also describe the implemenation and usage of some aspects in detail. The blog posts might be seen as the documentation.

The WriteableBitmapEx library is a collection of extension methods for the
WriteableBitmap. The WriteableBitmap class is available for all XAML flavors including Windows Phone, WPF, WinRT Windows Store XAML, (Windows 10) UWP and Silverlight. It allows the direct manipulation of a bitmap and can be used for image manipulation,
to generate fast procedural images by drawing directly to a bitmap and more.
The WriteableBitmap API is very minimalistic and there's only the raw
Pixels array for such operations. The WriteableBitmapEx library tries to compensate that with extensions methods that are easy to use like built in methods and offerGDI+ like functionality. The library extends the WriteableBitmap class with elementary and fast (2D drawing) functionality, conversion methods and functions to combine (blit) WriteableBitmaps.
The extension methods are grouped into different C# files using a partial class approach. It is possible to include just a few methods by using the specific source code files directly or the full functionality via the built binaries.
The latest binaries are always available as
NuGet package.
WriteableBitmapEx was also ported to Windows Embedded.
See the Issue Tracker for a list of features that will be added in the future.
GDI+ like drawing functionality for the WriteableBitmap.
Support for Windows Phone Silverlight, Windows Phone WinRT, desktop Silverlight, WPF, Windows 8/8.1 WinRT XAML and Windows 10 UWP.
