RotationFilter Class
Rotates the image around its center in a clock-wise direction.
Namespace: Lumia.Imaging.Transforms
Assembly: Lumia.Imaging (in Lumia.Imaging.dll) Version: 255.255.255.255
Syntax
public sealed class RotationFilter : IFilter,
__IRotationFilterPublicNonVirtuals
'Declaration
Public NotInheritable Class RotationFilter
Implements IFilter, __IRotationFilterPublicNonVirtuals
public ref class RotationFilter sealed : IFilter,
__IRotationFilterPublicNonVirtuals
Lumia.Imaging.Transforms.RotationFilter = function();
Type.createClass(
'Lumia.Imaging.Transforms.RotationFilter',
null,
Lumia.Imaging.IFilter,
Lumia.Imaging.Transforms.__IRotationFilterPublicNonVirtuals);
Remarks
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.
Examples
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);
