enable image brush to be only draw a portion of the source image

antonfirsov

Implementation and tests look good.

We need to clean up the terminology used in API naming and docs, because currently it feels confusing to me. The problem is that IPath can be used for many things in the Drawing library, it's name doesn't carry the purpose (which I personally dislike, but it's a common practice in drawing libraries). My recommendation is to use the term "Region" (or an equivalent unambiguously descriptive term) in parameter/property names & docs for IPath defining a region to fill, or boundary for a recursive processor.

We also need to find a better name for the new Clip method.

Update: Taking another look, I don't dislike Clip that much anymore, but I think we should still consider alternatives.

I would consider renaming path to region everywhere.

-        public IPath Shape { get; }
+        public IPath Path { get; }


I think "region" is a better name when it's about filling:

Suggested change

public IPath Path { get; }

public IPath Region { get; }

+        public static IImageProcessingContext Clip(


I think Clip is a very generic overloaded and ambiguous name, doesn't help API discoverability in this case.

I wouldn'be afraid of going verbose here, for example ProcessInsideRegion would be a better name for this.

JimBobSquarePants · 2021-07-25T15:27:22Z

@antonfirsov I've applied a lot of renaming and updated XML docs based on your suggestions. I found that I was straying into #94 territory though as I waded through each connected method so have stopped where I am for now.

I maintained Clip as the method name (I think people will get it) and renamed the processor ClipPathProcessor

I'm merging this. We can do a final API review before RC1
