Prerequisites
Description
This is one of those monster PRs that everyone hates but since it touches all image formats was unavoidable.
This PR stems from the v4 roadmap discussion here.
It does three things.
Two bridging metadata types
FormatConnectingMetadata
andFormatFrameConnectingMetadata
have been introduced along with interfacesIFormatMetadata
,IFormatMetadata<TSelf>
,IFormatFrameMetadata
,IFormatFrameMetadata<TSelf>
which enforce conversion APIs between all our format metadata types.Naming conventions, type usage, and behavior has also been normalized across all our metadata types.
PixelColorType
has been expanded to allow for exotic types not used in our own pixel formats and is now present alongsidePixelComponentInfo
andPixelAlphaRepresentation
in thePixelTypeInfo
instance returned withImageInfo
