示例1: RenderInternalAsync
private Task<RenderResult> RenderInternalAsync(IImageProvider source, Size sourceSize, IImageProcessor processor, RenderOption renderOptions)
{
if (source == null)
{
throw new NullReferenceException("source");
}
processor.OnBeforeRender();
var renderAtSourceSize = (renderOptions & RenderOption.RenderAtSourceSize) == RenderOption.RenderAtSourceSize;
var renderSize = processor.CanRenderAtPreviewSize && !renderAtSourceSize ? PreviewSize : sourceSize;
Debug.WriteLine(string.Format("RenderEffectAsync {0} sourceSize = {1}, renderSize = {2}", processor.Name,
sourceSize, renderSize));
var stopwatch = Stopwatch.StartNew();
var effect = processor.GetEffectAsync(source, sourceSize, renderSize);
if (effect.IsSynchronous)
{
return FinishRender(effect.Result, stopwatch, renderOptions, renderSize);
}
else
{
return effect.Task.ContinueWith(effectTask => FinishRender(effectTask.Result, stopwatch, renderOptions, renderSize), TaskContinuationOptions.OnlyOnRanToCompletion).Unwrap();
}
