Is there a way to get ID2D1Bitmap from an ID2D1Image ? ID2D1Effect::GetOutput() only returns ID2D1Image . I need ID2D1Bitmap , as it is feature rich.

@thebluetropice You could try to create a Bitmap ( ID2D1DeviceContext::CreateBitmap ) with D2D1_BITMAP_OPTIONS_TARGET flag , And then you could set and draw the effects output to this Bitmap. I suggest you could refer to the thread: https://stackoverflow.com/questions/31118397/direct2d-convert-id2d1image-to-id2d1bitmap

Thank you for the response.

Indeed, I read the thread you refer to before asking this question. However, it's uses ID2D1DeviceContext::SetTarget() to convert from ID2D1Image to ID2D1Bitmap, which is weird.
I am looking for better way here.

A comment in the answer says:

This is actually the correct way to do it (although with error handling :)

Is this the only way to convert from ID2D1Image to ID2D1Bitmap?

Edit: I guess yes, this is the only way... :I

As far as I'm concerned, this is the only way. It seems that you could only uses ID2D1DeviceContext::SetTarget() to convert from ID2D1Image to ID2D1Bitmap.
