public MetadataQueryReader GetMetadataQueryReader()Returns
GetThumbnail()
HRESULT IWICBitmapFrameDecode::GetThumbnail([Out] IWICBitmapSource** ppIThumbnail)
public BitmapSource GetThumbnail()Returns
TryGetColorContexts(ImagingFactory, out ColorContext[])
Get the ColorContext of the image (if any)
public HResult TryGetColorContexts(ImagingFactory imagingFactory, out ColorContext[] colorContexts)Parameters

Remarks
When the image format does not support color contexts,
TryGetColorContexts(ImagingFactory)
Get the ColorContext of the image (if any)
public ColorContext[] TryGetColorContexts(ImagingFactory imagingFactory)Parameters
imagingFactoryImagingFactory
Returns
- ColorContext[]
null if the decoder does not support color contexts; otherwise an array of zero or more ColorContext objects
