Use enumerations for ease of use

[HolyOne]

Hello,
I see that i have to input some string values as parameters which makes me go search a lot of documentation.
for example

NetVips.Image.Thumbnail(path, w, h, crop: "attention"))
Why not use

public enum CropParameters { attention , someotheroption, ... }

The reason for this was that passing strings was more dynamic (and maintainable), since there is no need to release a new NetVips version every time a new enumeration is added within libvips.

But I agree, I think using enumerations instead of strings makes more sense. I had an attempt to implement this, see commit 19486a7 on the enum branch. If you want to test this, you can use the nightly version of NetVips. Add the https://ci.appveyor.com/nuget/net-vips feed in the <packageSources> section of your NuGet.config:

<packageSources>
  <add key="netvips-nightly" value="https://ci.appveyor.com/nuget/net-vips" />
</packageSources>

And update NetVips to 2.0.0 (build number 239 - prerelease). I'll try to release this as v2.0.0 soon.

NetVips v2.0.0 is now available. Thanks for reporting this!
