v0.3.0

New

• SIMD support for the following functions using AVX2 (new default feature simd to enable this behavior)
  • tone::brightness()
  • tone::saturation()
  • colorspace::rgb_to_grayscale()
• simd module
  • adds_256_u8()
  • adds_n_256_u8()
  • deinterleave_3_rgb_256_u8()
  • deinterleave_4_rgb_256_u8()
  • avg_256_u8()
  • avg_alpha_256_u8()
  • avg_checked_256_u8()

Changes

• Switched from using f64 to f32 for speed
• Separated tone::brightness_lab() and tone::contrast_lab() into their own functions

Bug Fixes

• Fixed bug in tone::brightness()

v0.2.3

• Added optimizations for some functions

v0.2.2

• Made documentation more thorough

• Moved the math module into the util module

• Added filter::laplacian()

• Added filter::laplacian_of_gaussian()

• Added filter::normalize_laplacian()

v0.2.1

• Replaced enums::Tone::Xyz with enums::Tone::Lab, which seems to work better for brightness and contrast
  adjustments

• Added parallel feature for enabling multithreading

• Added PixelIter struct for iterating over an image by pixels

• Added morphology module functions:

  • erode()
  • dilate()
  • majority()
  • open()

v0.2.0

Structural Changes

• Separated functions in previous core module into separate modules
• Added multithreading support for some functions (indicated by the _par suffix in the function name) via
  rayon

Modifications

• image::Image::new() renamed to image::Image::from_slice()
• filter::median_filter() and filter::alpha_trimmed_mean_filter() re-implemented using a faster algorithm based on
  Ben Weiss' fast median filtering algorithm

New Stuff

• image::Image::from_vec()
• image::Image::from_vec_of_vec()
• image::Image::from_vec_of_slice()
• image::Image::get_pixel_unchecked()
• image::Image::get_pixel_mut_unchecked()
• util::get_2d_coords()
• util::math::cubic_weighting_fn()
• util::math::clamp_zero()
• util::math::sinc_norm()
• util::math::lanczos_kernel()
• util::math::separate_kernel()
• convert::scale_channels()
• enums::Scale::{Bicubic, Lanczos}
• From trait implementations between common Image<T> types
• transform::scale() now supports bicubic interpolation and Lanczos resampling methods for image scaling

Bug Fixes

• Fixed bug in filter::derivative_mask()

v0.1.1

Structural Changes

• Moved all core submodules to be directly under the core module
• Moved enum submodule out of the util module and into its own module

New Functions

• core::gamma
• core::median_filter
• core::alpha_trimmed_mean_filter
• core::bilateral_filter
• util::summed_area_table
• util::rectangular_intensity_sum
