dlib 0.14.0 - 9 Jul, 2018

No changes since dlib 0.14.0 beta1.

dlib 0.14.0 beta1 - 8 Jul, 2018

Important: dlib now officially doesn't support macOS. This is an act of protest against Apple's drop of OpenGL support. While you probably still can use dlib's platform-independent and Posix-based functionality under macOS, there's no guarantee that this will continue, and compatibility issues will not be addressed. Read detailed manifesto here.

  • dlib.image
    • Breaking change: SuperImage.pixelFormat now returns uint instead of PixelFormat. This allows extending dlib with custom pixel formats while maintaining compatibility with PixelFormat. Values from 0 to 255 are reserved for dlib, values 256 and above are application-specific. This change is just a new convention and will not break any existing logics, though explicit cast to PixelFormat may be required in some cases. Comparisons such as img.pixelFormat == PixelFormat.RGB8 will work fine.
    • PixelFormat.RGBA_FLOAT is now deprecated, use FloatPixelFormat.RGBAF32 from dlib.image.hdri instead.
    • Saving to HDR is now supported (saveHDR functions in dlib.image.io.hdr).
    • New filters: dlib.image.filters.histogram (generates an image histogram) and dlib.image.filters.binarization (image thresholding using Otsu's method).
    • ACES tonemapper (hdrTonemapACES) and average luminance function (averageLuminance) in dlib.image.hdri.
    • Improved dlib.image.canvas. Path rasterizer now natively does anti-aliasing. Fixed bug with rendering on non-square images.
  • dlib.audio
    • Synthesizer framework (dlib.audio.synth). It allows to write synthesizers and use them to 'render' sounds, like in DAWs. Three built-in synthesizers are available: SineWaveSynth, SquareWaveSynth, FMSynth. To write actual data to Sound objects, two functions are available: fillSynth and mixSynth.
  • dlib.math
    • New module dlib.math.smoothstep with sigmoid-like functions: hermiteSmoothstep, rationalSmoothstep.
  • dlib.core
    • DMD 2.081.0 compatibility fix in dlib.core.stream.
  • Misc
    • Added latest DMD (2.081.0, 2.080.1) and LDC (1.10.0) to Travis CI config. CI builds for macOS were stopped for reason mentioned above.

dlib 0.13.0 - 14 May, 2018

No changes since dlib 0.13.0 beta1.

dlib 0.13.0 beta1 - 9 May, 2018

  • dlib.async has been removed for security reasons. Currently there are no active contributors to maintain the package and fix bugs, so it is considered not safe to use due to potential data corruption or loss. There's async branch for those who still want to use it, but for new projects it is strongly recommended to consider using more actively developed alternatives, such as vibe-core or Tanya.
  • dlib.image
    • New module dlib.image.canvas that provides Canvas class, a vector graphics engine inspired by HTML5 canvas. Currently it supports rasterizing arbitrary polygons and cubic Bezier paths, filled and outlined. It renders to user-provided SuperImage.
    • Improved HDR file decoder. Now it supports HDR files with magic string #?RGBE.
    • Reinhard and Hable tonemappers in dlib.image.hdri: hdrTonemapReinhard and hdrTonemapHable.
    • New filters in dlib.image.filters.edgedetect: edgeDetectLaplace and edgeDetectSobel.

    • Fixed bugs in dlib.image.arithmetics module.
  • dlib.math
    • New functions in dlib.math.vector: reflect, refract, faceforward.
    • New functions in dlib.math.utils: min2 and max2.
  • dlib.geometry
    • New functions in dlib.geometry.bezier: bezierTangentVector2 and bezierTangentVector3.
  • Misc
    • Added latest DMD (2.080.0, 2.079.1) and LDC (1.9.0, 1.8.0) to Travis CI config.
    • dlib now does CI under Windows using AppVeyor.

dlib 0.12.2 - 7 Nov, 2017

  • Enum constants of type Vector now can be assigned to variables.

  • dlib.core
    • New module dlib.core.ownership - a Delphi-like object ownership system. Objects are registered to parent object, which automatically deletes them when gets deleted itself. In many cases this can be a convenient trade-off between fully automatic and fully manual memory management.

    • Nanosecond modification time precision support in stat under Posix.
  • dlib.math
    • New direct solver (solve) in dlib.math.linsolve based on LUP decomposition.
  • dlib.geometry
    • Frustum-sphere intersection test (intersectsSphere) for dlib.geometry.frustum.
  • dlib.coding
    • Breaking change: dlib.coding.huffman is merged with dlib.image.io.jpeg.

  • dlib.memory - new tools and interfaces to generalize memory allocation. There is Allocator interface, similar to Phobos' IAllocator, but simpler. There are also several implementations of this interface: Mallocator (malloc based allocator) and MmapPool (block based allocator for Posix systems with mmap/munmap support).
  • dlib.serialization - a new home for XML (and, hopefully, other markup languages in future). dlib.xml is deprecated, but left with public imports for compatibility purpose
    • XML parser (dlib.serialization.xml) is now fully GC-free
  • dlib.network
    • dlib.network.socket, a cross-platform socket API. Supports Windows and Posix
