Пример

Вот C#/VB.NET код, который демонстрирует, как добавить визуальный инструмент, который изменяет яркость видимой области просмотрщика изображений, в просмотрщик изображений.

VB.NET


''' <summary>
''' Adds the visual tool, which changes brightness of visible area of image viewer, to the image viewer.
''' </summary>
''' <param name="imageViewer">The image viewer.</param>
''' <param name="imageBrightness">The image brightness value in percents. Valid values are from -100 to 100.</param>
Public Sub AddVisualToolForProcessingVisibleAreaInImageViewer(imageViewer As Vintasoft.Imaging.Wpf.UI.WpfImageViewer, imageBrightness As Integer)
    ' create command for changing of image brightness
    Dim changeBrightness As New Vintasoft.Imaging.ImageProcessing.Color.ChangeBrightnessCommand()
    ' set the command parameters
    changeBrightness.Brightness = imageBrightness

    ' create an instance of the ImageViewerProcessingTool class
    Dim viewerProcessingTool As New Vintasoft.Imaging.Wpf.UI.VisualTools.WpfImageViewerProcessingTool()
    ' specify that visual tool must use the command for processing visible area in image viewer
    viewerProcessingTool.ProcessingCommand = changeBrightness

    ' set the tool as the current tool of the ImageViewer
    imageViewer.VisualTool = viewerProcessingTool
