How to create a custom Pixel Format?

[Jacbo1]

How do I implement a custom pixel format for R8? The docs say the pixel formats are extensible so I looked at the source code and tried implement an R8 pixel format by copying and adapting the A8 struct but then found out 2 of the methods called in the A8 struct are internal i.e. cannot be accessed from an implementing project. At least one of these is required for it to work. new PixelOperations() required as part of implementing IPixel<R8> and PixelTypeInfo.Create<R8>() (or maybe PixelTypeInfo itself) and internal only.

new PixelOperations() required

The PixelOperations<T> type is not abstract, and the constructor is public, you should be able to instantiate a new PixelOperations<R8>(). Subclassing is needed to optimize conversion operations: you can create your own R8PixelOperations : PixelOperations<R8> subclass and override methods with optimized ones.

PixelTypeInfo.Create<R8>() (or maybe PixelTypeInfo itself)

You can use one of the public constructors to instantiate a PixelTypeInfo. Create<TPixel> is really just a thin wrapper around them.
