Lumia.Imaging.Transforms.RotationFilter = function();

Type.createClass(
	'Lumia.Imaging.Transforms.RotationFilter',
	null,
	Lumia.Imaging.IFilter,
	Lumia.Imaging.Transforms.__IRotationFilterPublicNonVirtuals);

Dimensions of the resulting image are such that the rotated image fits snuggly inside it.

Areas outside the original image are rendered in black.

The resulting image dimensions may never exceed (16383, 16383). An exception will be thrown during rendering if this is the case.

using (var filterEffect = new FilterEffect(source))
{
    // Initialize the filter and add the filter to the FilterEffect collection
    var filter = new RotationFilter(15.0);

    filterEffect.Filters = new IFilter[] { filter };

    // Create a target where the filtered image will be rendered to
    var target = new WriteableBitmap(width, height);

    // Create a new renderer which outputs WriteableBitmaps
    using (var renderer = new WriteableBitmapRenderer(filterEffect, target))
    {
        // Render the image with the filter(s)
        await renderer.RenderAsync();

        // Set the output image to Image control as a source
        ImageControl.Source = target;
    }

    await SaveEffectAsync(filterEffect, "RotationFilter.jpg", outputImageSize);
