LocalBoostFilter Class

Manually boost and enhance images with unequal illumination.

Namespace: Lumia.Imaging.Adjustments
Assembly: Lumia.Imaging (in Lumia.Imaging.dll) Version: 255.255.255.255

Syntax

public sealed class LocalBoostFilter : IFilter, 
    __ILocalBoostFilterPublicNonVirtuals

'Declaration
Public NotInheritable Class LocalBoostFilter
    Implements IFilter, __ILocalBoostFilterPublicNonVirtuals

public ref class LocalBoostFilter sealed : IFilter, 
    __ILocalBoostFilterPublicNonVirtuals

Lumia.Imaging.Adjustments.LocalBoostFilter = function();

Type.createClass(
    'Lumia.Imaging.Adjustments.LocalBoostFilter',
    null,
    Lumia.Imaging.IFilter,
    Lumia.Imaging.Adjustments.__ILocalBoostFilterPublicNonVirtuals);

Remarks

The image is analyzed and segmented into a dark part and a light part. The two parts are processed separately and are finally blended together to produce a modified image.

Examples

using (var filterEffect = new FilterEffect(source))
{
    // Initialize the filter and add the filter to the FilterEffect collection
    var filter = new LocalBoostFilter(1.5, 0.8, 0.8, 0.8);

    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, "LocalBoostFilter.jpg", outputImageSize);
