January 25, 2019π Improvements since beta-5
Resize

~2.5x). On .NET Core 2.1 now we downscale images faster than System.Drawing (#731, #781) - Using
~30%less memory during resize (#731, #781) - #719 - Keep one pixel if aspect ratio respecting resize would set a dimension to 0.

Other
π New API-s and API changes
- Split pixel blending and alpha composition API-s (#641, #679)
- β Add API-s to preserve format-specific metadata after decoding images, so it won't be lost when they are being reencoded. (#693)
- Image formats are now public (#701)
- π¨ #741 - Add generic palette quantizer, refactor + werner palette
Optimizations
- #671 - Use span directly for DetectFormat
- β‘οΈ #710 - Optimized parallel pixel processing
- β‘οΈ #742 - Clean up and optimize byte<->float and Rgba32 <-> Vector4 conversion
- β‘οΈ #751 - Introduce optimized conversion methods for RGBA-like types

- #715 - Use clean buffer when detecting format
- #753 - Added missing length check that caused an ArgumentNullException (#750)
- #726 - Throw when crop rectangle exceeds source bounds.
- Mathematically correct Gaussian Blur (#789)

v1.0.0-beta5 Changes
August 05, 2018π₯ Breaking changes
π All processing extension methods have been moved to the
SixLabors.ImageSharp.Processingnamespace to improve API discoverability for vanilla VS and VS Code users. (#645) Sub namespaces likeSixLabors.ImageSharp.Processing.Transformsdo no longer exist! You have to remove these using statements from your code:using SixLabors.ImageSharp;using SixLabors.ImageSharp.PixelFormats;using SixLabors.ImageSharp.Processing; // The only namespace required for processing extensions!uΜΆsΜΆiΜΆnΜΆgΜΆ ΜΆSΜΆiΜΆxΜΆLΜΆaΜΆbΜΆoΜΆrΜΆsΜΆ.ΜΆIΜΆmΜΆaΜΆgΜΆeΜΆSΜΆhΜΆaΜΆrΜΆpΜΆ.ΜΆPΜΆrΜΆoΜΆcΜΆeΜΆsΜΆsΜΆiΜΆnΜΆgΜΆ.ΜΆTΜΆrΜΆaΜΆnΜΆsΜΆfΜΆoΜΆrΜΆmΜΆsΜΆ;ΜΆ // COMPILATION ERROR!
π
image.SavePixelData()APIs have been removed in favour ofimage.GetPixelSpan()(#628)π§
Configuration.ParallelOptionshas been replaced withConfiguration.MaxDegreeOfParallelism(#667)
π Improvements since beta 4:
- π Fixed all remaining issues with .NET Core 2.1
- Jpeg improvements:
- π Introduce
PixelResolutionUnitinImageMetaData, fix #490 (#649) - PNG improvements
- β‘οΈ Optimized font rendering by caching glyphs (#614)
- π Improved Gif and Quantization performance when using diffusion by
~600%(#637) - Cross target .NET Core 2.1 (#604)
- Histogram Equalization (#644)
- Deeper
System.MemoryAPI integration:- Span overloads for
Image.Load()andImage.DetectFormat()(#618) image.GetPixelSpan()andimage.GetPixelRowSpan()extension methods for fast pixel data manipulation (#607)Image.WrapMemory(...)for native interop use-cases (#660)- The
MemoryAllocatorAPI is now public and shared across all SixLabors projects (#665)

v1.0.0-beta4 Changes
May 31, 2018π Improvements since beta 3
- π Full support for .NET Core 2.1
- π Fixed a bug related to drawing large and complex shapes (eg. pages of text)
- Gradient brushes
- Projective non-affine transforms (tilt, perspective)
- π Improved the robustness of our Jpeg decoder:
