v2.0.0

Advisories and Breaking Changes

Major breaking changes

• Due to the new unmanaged memory engine, we had to redesign our pixel processing and low level memory management API-s. The most visible change is that the GetPixelRowSpan() methods have been replaced with ProcessPixelRows() variants. This was done to guarantee memory safety. For more details see:
  • 2.0 documentation on Working with Pixel Buffers
  • 2.0 documentation on Memory Management
  • Pixel processing breaking changes & API discussion - #1739
• Png and Jpeg now decode to pixels formats closer to the encoded format when using the non-generic API. (For example Jpeg now decodes to Image<Rgb24> instead of Image<Rgba32>.) This was done to reduce memory usage and remove some surprises for users.
• We've dropped the old NetStandard 1.3 target. This targeted frameworks not supported by Microsoft and was adding overhead to development.

Complete list of breaking PR-s

• Add Abgr32 pixel type, extend IPixel - #1886 via @ynse01, @antonfirsov, @JimBobSquarePants
• Remove netstandard 1.3 target - #1888 via @JimBobSquarePants
• ImageFormatDetector Configuration Cleanup - #1936 via @JimBobSquarePants
• Unmanaged pooling MemoryAllocator - #1730 via @antonfirsov
• Png - Preserve Pixel Format for Non-generic decode. - #1861 via @JimBobSquarePants
• Decode Jpeg into Rgb24 when pixel type not specified. - #1773
