1.0.0 beta5

Breaking changes

• All processing extension methods have been moved to the SixLabors.ImageSharp.Processing namespace to improve API discoverability for vanilla VS and VS Code users. (#645) Sub namespaces like SixLabors.ImageSharp.Processing.Transforms do 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!
u̶s̶i̶n̶g̶ ̶S̶i̶x̶L̶a̶b̶o̶r̶s̶.̶I̶m̶a̶g̶e̶S̶h̶a̶r̶p̶.̶P̶r̶o̶c̶e̶s̶s̶i̶n̶g̶.̶T̶r̶a̶n̶s̶f̶o̶r̶m̶s̶;̶ // COMPILATION ERROR!

• image.SavePixelData() APIs have been removed in favour of image.GetPixelSpan() (#628)
• Configuration.ParallelOptions has been replaced with Configuration.MaxDegreeOfParallelism (#667)

Improvements since beta 4:

• Fixed all remaining issues with .NET Core 2.1
• Jpeg improvements:
  • ~28% faster Jpeg Decoder (#643)
  • Fix #624 (Decoder bug, -> PR #625)
  • Fix #646 (ICC decoding bug, -> PR #647)
• Introduce PixelResolutionUnit in ImageMetaData, fix #490 (#649)
• PNG improvements
  • Exif support for PNG (#616)
  • Support for 16bit PNGs (#613)
• Optimized font rendering by caching glyphs (#614)
• Improved Gif and Quantization performance when using diffusion by ~600% (#637)
• Cross target .NET Core 2.1 (#604)
• Histogram Equalization (#644)
• Deeper System.Memory API integration:
  • Span overloads for Image.Load() and Image.DetectFormat() (#618)
  • image.GetPixelSpan() and image.GetPixelRowSpan() extension methods for fast pixel data manipulation (#607)
  • Image.WrapMemory(...) for native interop use-cases (#660)
  • The MemoryAllocator API is now public and shared across all SixLabors projects (#665)

1.0.0 beta4

Improvements since beta 3

• Full support for .NET Core 2.1
• Fixed a bug related to drawing large and complex shapes (eg. pages of text)
• Gradient brushes
• Projective non-affine transforms (tilt, perspective)
• Improved the robustness of our Jpeg decoder:
  • A large part of the implementation has been replaced, allowing to parse a wider range of incorrectly encoded images
  • Better ICC reader
• Basic System.Memory API integration: Image.LoadPixelData() and SavePixelData() are now able to consume spans
• Improved .Fill(color) performance and added a constructor initializing images with a default fill color

v1.0.0-beta3

Improvements since beta 2

• Breaking change: Refactored the namespaces to logical groups based on functionality.
• Introduced a full memory management API that allows fine grained control of how ImageSharp manages large buffers.
  • For the default pooling memory management implementation we managed to halve the memory footprint of the library without significant loss in speed.
• Made codecs easier to use. The performance of the Jpeg decoder is doubled since the first beta!
• Introduced a new metadata-only decoding API with the help of the community.
• Introduced new affine transform methods that allow the composition of affine transforms.
• Refactored all filters (Hue, Brightness, Saturation etc) to match the behaviour described in the W3C specification.
• Introduced static instances of reusable algorithms for use as method parameters.
• Fixed the resampling processes to correctly blend semi-transparent output.
• Many other performance improvements and bug fixes.

1.0.0 beta2

Beta Release

• Added new netstandard 2.0 target to take advantage of performance improvements
• Increased the speed of the Jpeg decoder by 100%-200% for most images
• Normalized and improved animated Gif output
• Revised API for IImageFrameCollection<T> (image.Frames). From now, it is responsible for managing the lifecycle of image frames. Added CloneFrame(idx) and ExportFrame(idx) methods to copy/move individual frames into new images.
• Various Png performance improvements and fixes
• Expanded range of decodable Bmp types
• ref returning extension methods for low-level/interop scenarios. (Only for advanced users, familiar with pointer arithmetics!)
• Many other bug fixes
