A bitmap library (think BitArray, BitVector32, or Bit Index -- not bmp) written in C# with more functionality than the .NET library options.
Bitmap.NET runs on .NET Standard 2.0, supports arbitrary bitmap lengths, and supports the following operations:
- Per-bit Get
- Per-bit Set
- Union with another bitmap
- Intersection with another bitmap
- Invert the bitmap
- Set a range of bits to a value
- Set all bits to a value
- Efficiently get the set of all
Truebits
Look at the test for some simple examples.
