Parameters

image

The Windows.UI.Xaml.Media.ImageSource object containing the image data to convert.

options

Options to control the conversion operation. Currently there are no extra options and the value of this parameter must be set to ConvertFromImageOptions.None

Return Value

WinRT

Microsoft WinRT currently offers support for 32-bits/pixels only. So the result from this method will always be a Leadtools.RasterImage object with RasterImage.BitsPerPixel equal to 32.

Use the ConvertToImageSource method to convert a LEADTOOLS Leadtools.RasterImage into a WinRT Windows.UI.Xaml.Media.ImageSource object.

The conversion works by copying the image data over to the new destination. Currently, there is no support for sharing memory between a Leadtools.RasterImage and a Windows.UI.Xaml.Media.ImageSource.

For more information refer to RasterImage and WinRT.

For an example, refer to RasterImageConverter.
