coloraide - 0.1.0a20

Published by facelessuser over 3 years ago

0.1.0a20

  • FIX: Fix lab-d65 which was not using the correct white point in all places.
coloraide - 0.1.0a19

Published by facelessuser over 3 years ago

0.10a19

  • FIX: Ensure that subclassed Color objects are normalized when performing operations with more than one color to
    prevent issues in case one subclassed object has overridden important functions.
  • FIX: Spaces like lab, lch, etc., which specify certain channels as percent only should require the color()
    format to only accept percentages for those channels and output those channels as percentages when converting to a
    string.
coloraide - 0.1.0a18

Published by facelessuser over 3 years ago

0.10a18

  • NEW: Refactor of internals.
  • NEW: interpolate and steps can now accept multiple colors and will return an interpolation function that spans all
    specified colors via the range of [0..1].
  • NEW: Better control over piecewise interpolation: setting stops, adjusting options per segment, etc.
  • NEW: compose can now accept multiple colors and will return a result where all colors are layered on top of each
    other.
  • NEW: new method does not need to be a classmethod. Make it a normal method on the instance.
  • NEW: Add Jzazbz and JzCzhz color spaces.
  • NEW: Add D65 variants of CIELAB, CIELCH, and XYZ.
  • NEW: Add ICtCp color space and Delta E ITP method.
  • FIX: Actually make mix default to lab like interpolate and friends do.
coloraide - 0.1.0a17

Published by facelessuser over 3 years ago

0.1.0a17

  • FIX: Ensure that both the Bradford CAT and the XYZ transformation matrix all use ASTM E308-01 white points. This fixes a number of conversion issues when going to and from D65 to D50 color spaces.
coloraide - 0.1.0a16

Published by facelessuser over 3 years ago

0.1.0a16

  • NEW: Make mix use the same space logic as interpolate and step. Colors are mixed in CIELAB unless space is set to a different color space.
  • NEW: Add support for blend modes as specified in [Compositing and Blending Level 1][compositing-level-1].
  • NEW: Rename overlay to compose as all compositing (including blend modes) is done through compose now.overlay is still present and is deprecated and will be removed at some future point before a stable release. compose will assume sRGB space unless a different space is specified, but overlay will function as it always did.
  • FIX: Fix some small internal issues with in_place logic.
coloraide - 0.1.0a15

Published by facelessuser over 3 years ago

0.1.0a15

  • NEW: The adjust parameter on interpolate, steps, and mix has been dropped. Instead, a general purpose method
    has been added to the Color object to mask one or more channels at a time. This can be used to create a temporary
    color with masked channels for the purpose of interpolation.
  • FIX: Ensure that when alpha is NaN that it is handled in overlay.
  • FIX: When using raw data in the color() function, and there is too little data, fill data with NaN.
  • FIX: Fix issue where API interpolate method does not pass out_space parameter down.
  • FIX: Disabling or forcing alpha did not work properly for HSL colors via to_string.
  • FIX: contrast and luminance should use XYZ with a D65 white point, not the default XYZ space which uses a D50
    white point.
  • FIX: Fix bug in Delta E 2000 algorithm.
coloraide - 0.1.0a14

Published by facelessuser over 3 years ago

0.1.0a14

  • NEW: sRGB string output parameter hex_upper has been renamed to just upper. Expose it in documentation as well.
coloraide - 0.1.0a13

Published by facelessuser over 3 years ago

0.1.0a13

  • FIX: More efficient calculation of CIELAB, following CIE 15.3:2004. Results are still the same, but it makes the math a little simpler.
  • FIX: HSV did not always set hue to NaN when saturation was 0.
  • FIX: Give better conversion results by having HWB colors pass through HSV instead of sRGB.
  • FIX: Fix slight issue with REC.2020 and ProPhoto color space conversion. Small issue when using <= when < was desired.
coloraide - 0.1.0a12

Published by facelessuser over 3 years ago

0.1.0a12

  • FIX: More stable saturation calculation for HSL to ensure divide by zero doesn't occur. 2(V - L) / (1 - abs(2 * L - 1)) is likely to yield zero in the denominator when L is very small, while the equivalent (V - L) / min(L, 1 - L) is not.
coloraide - 0.1.0a11

Published by facelessuser over 3 years ago

0.1.0a11

  • FIX: Ensure that when hex, compress, and names is enabled in to_string for srgb that colors will still match the color name if the color can be compressed.
coloraide - 0.1.0a10

Published by facelessuser over 3 years ago

0.10a10

  • FIX: Address two divide by zero cases in HSL algorithm. Was missing some special cases when luminance equals 1 or 0.
coloraide - 0.1.0a9

Published by facelessuser over 3 years ago

0.1.0a9

  • FIX: Ensure all cases, in regards to gamut mapping, are done the same.
coloraide - 0.1.0a8

Published by facelessuser over 3 years ago

0.1.0a8

  • NEW: Remove workaround to force cylindrical colors to overlay in non-cylindrical spaces. Allow colors to be overlaid in any color space. Original issues related to allowing cylindrical spaces as been fixed. Overlaying in cylindrical spaces may not make sense, but it is no longer prohibited.
  • FIX: Ensure color comparison will yield true if two channels have NaN.
coloraide - 0.1.0a7

Published by facelessuser over 3 years ago

0.1.0a7

  • FIX: Fix issue with translation of an input that is compressed hex with a specified alpha.
coloraide - 0.1.0a6

Published by facelessuser over 3 years ago

0.1.0a6

  • FIX: Don't return detached color spaces from steps. Ensure they are wrapped with a Color object on return.
coloraide - 0.1.0a5

Published by facelessuser over 3 years ago

0.1.0a5

  • FIX: Fix an issue where update can fail due to a color space detached from a parent.
  • FIX: Adjust fit tolerance to be a little more forgiving, but make an adjustment for in_gmaut in relation to
    HSL as saturation can be wildly out of range for an sRGB color that is only slightly out of gamut.
  • FIX: Ensure in_gamut handles NaN properly.
coloraide - 0.1.0a4

Published by facelessuser over 3 years ago

0.1.0a4

  • NEW: Use NaN to track undefined hues.
  • NEW: Remove is_hue_null and add new API function is_nan to test if any channel is currently set to NaN.
  • NEW: Remove get_default from the Color class and instead allow properties that can be overridden when
    subclassing the Color object.
coloraide - 0.1.0a3

Published by facelessuser over 3 years ago

0.1.0a3

  • FIX: Color object API was missing the ability to receive the premultiplied argument.
coloraide - 0.1.0a2

Published by facelessuser over 3 years ago

0.1.0a2

  • NEW: Expose access to srgb-linear color space. This is mainly for development and testing and not listed in docs currently.
  • FIX: Cylindrical spaces, when calling overlay can now request to be overlaid in a different space. This is because alpha composition does not work well in cylindrical spaces. HSL, HSV, and HWB will now request overlay to be done in sRGB, and LCH will request overlay to be done in LAB.
  • FIX: Add support for premultiplied alpha when interpolating via premultiplied option.
coloraide - 0.1.0a1

Published by facelessuser over 3 years ago

0.1.0a1

  • NEW: Initial alpha release. Library is experimental and API is unstable.
