This release moves some functionality out of DitherPunk and into ColorQuantization.jl and UnicodeGraphics.jl.
braille is faster and supports new printing methods via UnicodeGraphics.jl,
e.g. braille(img, method=:block) (#97)- Add support for
AbstractColorQuantizers from ColorQuantization.jl for color palette dithering (#98)
Fix bug in DomainError (8fae2d)
Move clustering functionality into ColorQuantization.jl (#98)- Add Aqua.jl quality assurance tests (#99)
- Update dependencies (#98)
Replace UnicodePlots.jl dependency with custom braille implementation (#91)- Revert default metric to
DE_2000 for higher image quality (#92)
Update documentation to show off new functionality (#88)
- Use faster default color difference metric
DE_AB (#87)
Note: this was reverted in PR #92, released in DitherPunk v3.0.3.
This breaking release of DitherPunk raises the minimum Julia version requirement from 1.0 to 1.6 (#82).
- Add default method
FloydSteinberg, such that dither can be called without passing an algorithm (477c98e)
- Add default method for
braille (#85)
- Add option to invert
braille output (#85)
- Lazily load Clustering.jl and UnicodePlots.jl (#77)
- Updated docs (#73)
Refactored ErrorDiffusion algorithms:
Deprecate keyword color_space (#73)- Remove
colorspace argument (#84)
- Turn
clamp_error into a keyword argument (#86)
- Performance improvements (#73)
- Drop OffsetArrays.jl dependency (#73)
- Column-first iteration (#80)
- Fix bug where kwargs were not accessible in
SimpleErrorDiffusion (#73)
- Fix colormap index overflow bug (#78)
- Downsample image before clustering (#71)
- Type stability fixes (#66)
- Fix doc build (#65)
- Color space for error diffusion can now be selected. Defaults to
XYZ, a change from previous RGB color space. Changes outputs and speeds up color error diffusion. (#63)
- Speed up color ordered dithering. (#62)
- Better docstrings for error diffusion algorithms. (#63)
- Added ASCII dithering example to docs. (#64)
- Ordered dithering algorithms now support custom color palettes. (#53)
- Color palette generation with Clustering.jl has been made accessible as
DitherPunk.get_colorscheme. (#58)
- Fixed docstring warnings. (#56)
- Added three advanced examples to docs. (#58)
- Color dithering methods now return IndirectArrays. (#47)
- Performance enhancements. Most noticeable for color methods. (#47)
- Dropped dependency on TiledIteration. (#47)
invert_map is now a keyword argument of ordered dithering constructors. (#50)
This release introduces some breaking changes due to an API overhaul and adds new functionality through conditional dependencies:
- Dithering color images without specifying a color palette will now automatically apply per-channel binary dithering. (#45)
- Because of the previously mentioned change,
SeparateSpace and its type AbstractFixedColorDither are not needed anymore and were removed. (#45)
- Enhanced error message when trying to use color palettes on methods that don't support them (Julia >=1.5). (#45)
- Support for ColorSchemes.jl. (#45)
- Support for Clustering.jl: automatically generate color palettes via K-means clustering. (#45)
- Support for UnicodePlots.jl: print binary images using Unicode Braille patterns with
braille . (#45)
- Error diffusion kwargs are now accessible. (#45)
